Can You Reheat Salmon? The Complete UK Guide to Safe Reheating

Can you reheat salmon? Leftover salmon is one of life's small pleasures — unless you ruin it by reheating it the wrong way. Whether it's a fillet from last night's dinner, a slice of salmon en croûte, or a bowl of salmon pasta, the question is the same: can you reheat salmon safely?

Quick Overview
This guide explains can you reheat salmon safely, including when it is safe, when it is not, and the key food safety rules to follow when storing and reheating leftovers.

Whether you are reheating a plain salmon fillet or leftover dishes like pasta, rice, fishcakes, or en croûte, this guide walks you through:
✅ The safest way to cool and store cooked salmon
✅ How to reheat salmon using the oven, air fryer, hob, microwave, and other methods
✅ Why salmon should only be reheated once
✅ Common mistakes that increase food poisoning risk
✅ FAQs like can you reheat salmon the next day, can you reheat salmon twice, and more

The short answer is yes. You can reheat salmon, and when it is done correctly, it can taste nearly as good as it did fresh from the oven or pan. The key is to use gentle heat, store it properly, and reheat it only once.

According to the Food Standards Agency (FSA), there are an estimated 2.4 million cases of foodborne illness in the UK each year. Improper food handling and reheating practices, including reheating fish incorrectly or leaving it at unsafe temperatures for too long, can increase the risk of food poisoning. While salmon is generally safe to reheat, following proper food safety guidance helps ensure both quality and safety.

This guide explains how to reheat salmon using a range of methods, including the oven, air fryer, hob, and microwave. It also provides specific guidance for reheating salmon pasta, salmon en croûte, salmon fishcakes, salmon patties, and other leftover salmon dishes, along with essential food safety recommendations to help keep your leftovers safe to eat.

How Many Times Can You Reheat Salmon?

You should only reheat salmon once. The Food Standards Agency (FSA) recommends reheating any food — including fish — only a single time. Reheating salmon multiple times increases the risk of bacterial growth and foodborne illness, and each time it is reheated, the quality, texture, and flavour will continue to deteriorate.

While it is technically possible to reheat some foods safely more than once (provided they are properly stored and reach the correct temperature each time), salmon is particularly unforgiving. It dries out quickly, and its delicate oils can develop a strong, unpleasant odour with repeated heating.

The guidance is clear: reheat only the amount you plan to eat. If you have a large portion of leftover salmon, divide it into smaller portions before refrigerating so you only ever reheat what you need.

This is an important consideration when asking can you reheat salmon, as safe handling and portion control are just as important as the reheating method itself.

UK Food Safety Rules: What You Need to Know First

Before you reheat salmon — or consider can you reheat salmon and rice safely — three core food safety rules apply: cool food quickly after cooking, store it correctly in the fridge, and reheat it thoroughly until piping hot.

The Food Standards Agency (FSA) advises reheating food to at least 75°C in the centre — a temperature sufficient to destroy harmful bacteria that may develop during storage.

Here is what UK food safety guidance says specifically about fish and salmon:

• Cool it within one hour of cooking. Leaving cooked salmon at room temperature for too long allows bacteria to multiply in the food hygiene “danger zone” (between 8°C and 60°C).
• Refrigerate promptly. Store in an airtight container at or below 5°C.
• Consume within 2–3 days. Food safety experts recommend eating refrigerated cooked fish within this timeframe.
• Reheat only once. The FSA guidance is clear: food should not be reheated more than once.
• Ensure it is piping hot throughout. Steam should be visible and there should be no cold spots. If using a food thermometer, the centre should reach at least 75°C.
• When in doubt, discard. If the salmon smells off, looks slimy, or has been left out of the fridge for more than two hours, it should not be eaten.

For dishes containing fish and dairy — such as salmon pasta or salmon en croûte with cream cheese — extra caution is advised, as these ingredients can shorten shelf life. In such cases, many food safety guidelines recommend consuming within one to two days.

How to Store Leftover Salmon Correctly 

Correct storage is the foundation of safe reheating. To safely handle leftovers — including when considering can you reheat salmon and rice — cool cooked food within one hour, store it in an airtight container, refrigerate at or below 5°C, and consume within 2–3 days.

Do not leave salmon covered on the worktop or loosely wrapped in foil at room temperature, as this increases the risk of bacterial growth.

Practical storage tips:

• Allow salmon to cool for no more than 30–60 minutes before refrigerating.
• Use an airtight container to preserve moisture and prevent odours spreading in the fridge.
• Store salmon separately from ready-to-eat foods to avoid cross-contamination.
• If combining salmon with rice, refrigerate promptly. Rice requires extra care as it can contain Bacillus cereus spores, which survive cooking and may multiply if left at room temperature.

The Oven Method (Best Overall) {#oven-method}

The oven is the best overall method for reheating salmon. It heats the fish gently and evenly, preserving moisture and texture without drying it out or producing a strong fishy odour. When considering can you reheat salmon, the oven method is widely regarded as the most reliable and food-safe approach. Set your oven to 160°C fan / 180°C conventional, loosely cover the salmon with foil, and reheat for 10–15 minutes until piping hot throughout.

Step-by-Step Instructions

• Remove salmon from the fridge and allow it to sit at room temperature for about 10 minutes. This helps it reheat more evenly and is an important step when asking can you reheat salmon safely.
• Preheat your oven to 160°C fan / 180°C conventional (Gas Mark 4).
• Place the salmon on a baking tray or oven-safe dish.
• Add moisture such as a drizzle of olive oil, a squeeze of lemon juice, or a splash of water.
• Cover loosely with foil to trap steam and retain moisture.
• Reheat for 10–15 minutes, depending on thickness.
• Ensure it is piping hot throughout before serving (at least 75°C in the centre).

Tips for Oven Reheating

• Thicker fillets may need up to 15 minutes, while thinner pieces may only need 8–10 minutes.
• Avoid high heat, as it will dry out the fish and negatively affect texture.
• A low and slow approach is best for anyone wondering can you reheat salmon without losing quality.

The Air Fryer Method (Quickest and Easiest) {#air-fryer-method}

The air fryer is a fast and effective method for reheating salmon, producing a lightly crisp exterior while keeping the inside moist. If you are asking can you reheat salmon, the air fryer is one of the most convenient modern solutions. Preheat to 180°C and heat for 5–7 minutes until piping hot.

Step-by-Step Instructions

• Preheat the air fryer to 180°C for 2–3 minutes.
• Place the salmon in the basket, skin-side down if applicable. Avoid overcrowding.
• Add a light drizzle of oil or a squeeze of lemon if needed.
• Cook for 5–7 minutes, checking halfway through.
• Ensure it is piping hot throughout before serving.

Tips for Air Fryer Reheating

• Excellent for salmon skin, which becomes crisp while the inside stays tender.
• Salmon en croûte and salmon Wellington reheat well at 180°C for around 10 minutes.
• Fishcakes and salmon patties also reheat well, becoming crisp on the outside and hot in the centre.
• Compared with can you reheat salmon in the microwave, the air fryer generally gives better texture and flavour.

The Skillet Method (Best for Crispy Edges) {#skillet-method}

Reheating salmon in a skillet is quick and enhances flavour by creating lightly crispy edges. Heat a non-stick pan over a medium-low heat, add a small amount of butter or olive oil, and gently warm the salmon for 2–3 minutes per side. If you are considering can you reheat salmon, this method is ideal for fillets and fishcakes.

Step-by-Step Instructions

• Heat a non-stick frying pan over medium-low heat (do not use high heat).
• Add a teaspoon of butter or olive oil and allow it to melt gently.
• Place the salmon in the pan, skin-side down if applicable.
• Cook for 2–3 minutes per side, turning gently.
• Baste with pan juices or a splash of water to maintain moisture.
• Ensure the centre is piping hot before serving.

Tips for Skillet Reheating

• A squeeze of lemon at the end improves flavour and reduces any fishy aroma.
• Works particularly well for fishcakes and salmon patties.
• Low heat is essential for anyone asking can you reheat salmon without overcooking it.

The Stovetop Method (Fast and Flexible) {#stovetop-method}

The hob is the best method for reheating salmon combined with sauces, pasta, or rice. When considering can you reheat salmon pasta, the stovetop is the most effective way to maintain texture and prevent drying out.

It is also important when thinking about can you reheat salmon in the microwave, as microwave reheating can sometimes cause uneven heating in mixed dishes.

For Salmon Pasta

• Add pasta to a pan with a small splash of water or cream.
• Heat gently over low-medium heat, stirring regularly.
• If using a cream-based sauce, add a tablespoon of cream to restore texture.
• Heat until steaming hot throughout.
• This is especially important when considering can you reheat salmon pasta safely.

For Salmon and Rice

• Place rice in a pan with a splash of water.
• Cover with a lid and heat gently over low heat, stirring occasionally.
• Ensure both rice and salmon are steaming hot throughout before serving.

Food Safety Note

• Rice should always be cooled within one hour of cooking, refrigerated promptly, and only reheated once.
• This is especially important when considering can you reheat salmon with rice, due to the higher food safety risks associated with improperly stored rice.

The Microwave Method (Use With Caution) {#microwave-method}

You can reheat salmon in the microwave, but it requires care. When considering can you reheat salmon, the microwave is possible but not the preferred method due to uneven heating and texture loss. Place the salmon in a microwave-safe dish, cover with a damp piece of kitchen roll or a microwave-safe lid, and heat at 50% power in 60–90 second bursts, checking between each interval. Lower power helps reduce the risk of overcooking and minimises strong fish odour.

If the oven, air fryer, or hob is not an option, the microwave can be used — but it is widely regarded as the least recommended method.

Step-by-Step Instructions

• Place salmon in a microwave-safe dish.
• Add a very small splash of water to create gentle steam.
• Cover with a damp sheet of kitchen roll or a microwave-safe lid to retain moisture and contain odour.
• Microwave at 50% power in 60–90 second bursts.
• Check and turn between bursts to ensure even heating.
• The salmon is ready when it is hot throughout with no cold spots.
• Allow it to stand for 30 seconds before serving, as heat continues to distribute after microwaving.

Microwave Reheating for Salmon Pasta

When asking can you reheat salmon pasta in the microwave, the answer is yes — and it is generally more forgiving than reheating a plain fillet. Add a small splash of water or cream, cover loosely, and heat in 60–90 second intervals at medium or full power, stirring between each burst to ensure even heating.

This method works reasonably well for creamy pasta dishes, but texture and sauce consistency may still be affected compared with stovetop reheating. For best results, ensure the dish is steaming hot throughout before serving.

Why You Should Avoid the Microwave for Salmon {#avoid-microwave}

The microwave is the least recommended method when considering can you reheat salmon, as it heats unevenly, can dry out the fish quickly, and often produces a strong fishy odour. The high heat can overcook the outside while leaving the centre underheated.

This concern also applies when asking can you reheat salmon en croute or can you reheat salmon wellington — microwave reheating can cause pastry to become soggy while the filling heats unevenly, reducing both texture and quality.

From a food safety perspective, uneven heating is also important. The Food Standards Agency (FSA) notes that microwaves can heat food in “pockets”, meaning cold spots may remain if food is not stirred or turned properly. This is particularly relevant when evaluating can you reheat salmon safely in a microwave.

For dishes like can you reheat salmon en croute or can you reheat salmon wellington, the microwave is especially unsuitable because pastry requires dry, even heat to maintain structure and crispness.

For plain salmon fillets, the result is often a dry, slightly rubbery texture with a noticeably stronger aroma. This can also affect kitchen odours, as the smell tends to linger more when microwaved.

If you are specifically asking can you reheat salmon pasta in the microwave, it is the most acceptable microwave use case, but still requires careful stirring and short bursts to avoid uneven heating.

If the microwave is your only option, the 50% power method described above will give the safest and most controlled results. However, for best quality and consistency, the oven, air fryer, or hob remains strongly recommended based on both culinary practice and food safety guidance.

Reheating Specific Salmon Dishes {#specific-dishes}

Can You Reheat Salmon the Next Day?

Yes. Cooked salmon can be safely reheated the next day, provided it was cooled within one hour of cooking, stored correctly in the fridge at below 5°C, and reheated until piping hot throughout. When considering can you reheat salmon the next day, food safety guidance from the Food Standards Agency (FSA) is clear: it must be consumed within 2–3 days of cooking and only reheated once.

Can You Reheat Salmon and Rice?

Yes, but with care. Both salmon and rice must be piping hot throughout when reheated. Rice carries specific food safety risks because it can contain Bacillus cereus spores that survive cooking and multiply at room temperature.

• Cool rice within one hour of cooking.
• Refrigerate immediately at or below 5°C.
• Reheat only once and ensure it is steaming hot throughout.

The hob or microwave (with added moisture and frequent stirring) are both suitable methods when preparing rice-based dishes alongside salmon. This is especially important when considering can you reheat salmon safely in mixed meals.

Can You Reheat Salmon Pasta?

Yes. Salmon pasta reheats well on the hob or in the microwave. When asking can you reheat salmon pasta, the key factor is maintaining moisture and preventing the sauce from splitting.

• Add a splash of cream or milk for cream-based sauces.
• Heat until steaming hot throughout.
• Consume within 1–2 days, especially if dairy is included.

Because this dish combines fish and dairy, it has a shorter safe storage window compared with plain salmon.

Can You Reheat Salmon Pasta in the Microwave?

Yes, salmon pasta can be reheated in the microwave and is generally more forgiving than a plain fillet. If you are asking can you reheat salmon in the microwave, pasta dishes are one of the better-use cases.

• Use 50–70% power.
• Add a splash of water or cream.
• Heat in 60–90 second intervals, stirring between each burst.
• Ensure it is piping hot throughout before serving.

Can You Reheat Salmon En Croûte?

Yes, but the oven or air fryer are strongly recommended. When considering can you reheat salmon en croute, the microwave should be avoided as it makes puff pastry soggy and heats the filling unevenly.

• Oven: 160°C fan / 180°C conventional for around 15 minutes.
• Air fryer: 180°C for approximately 10 minutes.

Both methods help preserve pastry texture while ensuring the filling is piping hot. Store in an airtight container and consume within 2–3 days, ideally within 2 days if dairy-based fillings are used.

Can You Reheat Salmon Wellington?

Yes. Salmon Wellington is the same dish as salmon en croûte, and the terms are interchangeable. The same reheating guidance applies: oven at 160°C fan for 15 minutes or air fryer at 180°C for around 10 minutes. Always ensure it is piping hot throughout before serving.

Can You Reheat Salmon Fishcakes?

Yes. When asking can you reheat salmon fishcakes, the answer is yes — and they reheat very well using dry heat methods.

• Oven: 180°C fan for 10–12 minutes
• Air fryer: 180°C for 6–8 minutes
• Hob: medium-low heat with a little oil or butter, 3–4 minutes per side

All methods produce a crispy exterior and a hot, well-textured interior. Avoid the microwave, as it can make fishcakes soggy and unevenly heated.

Can You Reheat Salmon Patties?

Yes. Salmon patties reheat very well, and when considering can you reheat salmon patties, the skillet method is particularly effective.

• Skillet (best method): medium-low heat with a small amount of oil, 2–3 minutes per side
• Air fryer: 180°C for 6–8 minutes

Both methods ensure a crisp exterior and evenly heated centre. Always confirm they are piping hot throughout before serving.

Can You Reheat Salmon Twice?

No. You should not reheat salmon twice. The Food Standards Agency advises reheating food only once. When considering can you reheat salmon, reheating more than once significantly increases the risk of bacterial growth and reduces quality.

Only reheat the portion you intend to eat.

Can You Reheat Salmon in the Oven?

Yes — and the oven remains the best overall method. When asking can you reheat salmon, the oven is the most reliable option for both safety and texture.

• 160°C fan / 180°C conventional
• Cover loosely with foil
• Add a small amount of moisture
• Heat for 10–15 minutes until piping hot throughout

Mistakes to Avoid When Reheating Salmon {#mistakes}

The most common mistakes when reheating salmon include using excessive heat, failing to cover the fish, skipping moisture, improper storage, and reheating more than once. Avoiding these errors is essential when considering can you reheat salmon safely and effectively.

1. Using Too High a Heat

High heat dries out salmon quickly and creates a strong fishy smell. Always use moderate temperatures regardless of method.

2. Not Covering the Salmon

Uncovered salmon loses moisture quickly. Always use foil in the oven or a damp cover in the microwave.

3. Forgetting to Add Moisture

A small amount of oil, water, or lemon juice significantly improves texture and prevents dryness.

4. Reheating from Frozen Without Thawing

Always defrost in the fridge overnight. The FSA advises against thawing at room temperature due to bacterial risk.

5. Leaving Salmon Out Too Long

If salmon has been left out for more than one hour, it may no longer be safe. When in doubt, discard it.

6. Reheating Salmon More Than Once

Only reheat once and only the portion you plan to eat.

7. Expecting Freshly Cooked Quality

Even well-reheated salmon will differ slightly from fresh. This is normal and should be expected when considering can you reheat salmon.

Pro Tip: Try It Cold Instead {#try-it-cold}

One of the best-kept secrets about leftover salmon is that it often tastes better cold than reheated. Cold salmon has a firm texture and clean flavour without the dryness or odour sometimes associated with reheating. It is perfectly safe to eat cold, provided it has been stored correctly. (food.gov.uk)

Cold salmon works well:

• Flaked over a green salad with lemon and capers
• In sandwiches or wraps with cucumber and dill cream cheese
• Mixed into cold pasta with a light dressing
• On crackers with crème fraîche
• With new potatoes and mustard dressing

For anyone asking can you reheat salmon the next day, cold consumption is often a practical and high-quality alternative that avoids reheating altogether.

Quick-Reference Reheating Guide {#quick-reference}

Storage reminders:

• Cool within 1 hour of cooking
• Refrigerate at below 5°C
• Consume within 2–3 days (1–2 days if combined with dairy)
• Reheat once only
• Must be piping hot (minimum 75°C at centre) before serving

Frequently Asked Questions {#faqs}

Can you reheat salmon safely?

Yes, you can reheat salmon safely, provided you follow basic food safety rules. When considering can you reheat salmon, it is essential to cool it within one hour of cooking, store it in an airtight container in the fridge at below 5°C, and consume it within 2–3 days. When reheating, ensure it is piping hot throughout — at least 75°C in the centre — and only reheat it once.

How many times can you reheat salmon?

Only once. The Food Standards Agency (FSA) recommends reheating food only a single time. When asking can you reheat salmon twice, the answer is no — reheating more than once increases the risk of bacterial growth and significantly reduces quality, resulting in dry, less palatable fish.

Can you reheat salmon the next day?

Yes. Salmon can be safely reheated the next day if it has been properly cooled and refrigerated within one hour of cooking. If you are asking can you reheat salmon, the key requirement is correct storage and reheating to piping hot throughout. For best results, use the oven or air fryer.

Can you reheat salmon in the microwave?

Technically yes, but it is not recommended. When considering can you reheat salmon in the oven, the oven or air fryer will always provide better texture and more even heating. Microwaves tend to heat unevenly, dry out the fish, and produce a stronger fishy odour.

If you must use a microwave:

• Use 50% power
• Heat in 60–90 second intervals
• Cover with a damp sheet of kitchen roll
• Check and turn between bursts
• Ensure there are no cold spots before eating

Can you reheat salmon pasta in the microwave?

Yes, salmon pasta reheats more successfully in the microwave than a plain fillet because the sauce helps distribute heat. Add a splash of water or cream, cover, and heat in 60–90 second bursts at medium power, stirring between each cycle. This is a practical example of can you reheat salmon in the microwave safely when handled correctly.

Can you reheat salmon en croûte or salmon Wellington?

Yes. The oven (160°C fan / 180°C conventional for around 15 minutes) and air fryer (180°C for around 10 minutes) are the best methods. If you are considering can you reheat salmon in the oven, this is the preferred option for pastry-based dishes.

Avoid the microwave, as it will make the puff pastry soggy and the filling unevenly heated. Always ensure it is piping hot throughout before serving, and consume within 2 days for best quality.

Can you reheat salmon fishcakes or salmon patties?

Yes. Salmon fishcakes and patties reheat very well and maintain texture when handled correctly.

• Air fryer: 180°C for 6–8 minutes
• Oven: 180°C fan for 10–12 minutes
• Hob: medium-low heat with a little oil, 3–4 minutes per side

These methods produce a crispy exterior and hot centre. Avoid the microwave if you want to maintain texture and flavour. When asking can you reheat salmon, these are among the most reliable leftover formats.

Is it safe to eat salmon that has been left out overnight?

No. Cooked salmon should not be eaten if it has been left at room temperature for more than two hours. After this point, bacteria can multiply rapidly in the food hygiene “danger zone” (8°C–60°C). If salmon has been left out overnight, it should be discarded.

Can you reheat frozen cooked salmon?

Cooked salmon should be fully defrosted in the fridge overnight before reheating. If you are asking can you reheat salmon in the oven, this method works best after proper thawing.

• Defrost in the fridge at below 5°C
• Reheat using the oven, air fryer, or hob
• Never defrost at room temperature

What temperature should reheated salmon reach in the UK?

The Food Standards Agency (FSA) advises that reheated food should be piping hot throughout. Practically, this means the centre should reach at least 75°C. When considering can you reheat salmon, this temperature ensures harmful bacteria are destroyed.

If you do not have a food thermometer, check that:

• Steam is rising from the fish
• There are no cold spots in the thickest part
• The salmon is evenly hot throughout

Conclusion

So, can you reheat salmon? Yes — as long as it is handled safely and correctly.

Cool it quickly, store it properly in the fridge, and reheat it only once until piping hot throughout. The oven and air fryer are the best methods for fillets, while the hob works best for dishes like pasta, rice, fishcakes, and patties. The microwave should be considered a last resort due to uneven heating and texture loss.

For dishes like salmon en croûte or salmon Wellington, the oven or air fryer is strongly recommended to preserve pastry quality. If you are wondering can you reheat salmon in the oven, this is the most reliable and widely recommended method.

And remember — sometimes the best option is not reheating at all. Cold salmon is safe, convenient, and often delicious in salads, sandwiches, or light lunches.

For official guidance, refer to the Food Standards Agency at food.gov.uk, and always discard salmon if it shows signs of spoilage or has been stored incorrectly.
