Eating salmon in its fresh form is the best way to go. But if you know how to reheat salmon, leftover salmon can still taste incredible! 

Salmon is one of the best fish you can eat, but what happens when it gets reheated? Is that even possible?

The answer is yes; if done right, your salmon will be just as good as the day you made it. 

This guide will show you how to reheat salmon in the oven safely and easily. 

With that said, let’s begin. 

How To Reheat Salmon Using The Oven Method


After you’ve taken the salmon out of its packaging, leave it out for about an hour before cooking. If you put the fish back in the fridge immediately, it’ll start to cool down again and won’t heat up properly. 

However, you don’t want to leave it out for too long because it’ll get too warm and start to cook itself (which isn’t ideal).

Remove From Packaging And Cover With Foil

Remove salmon from its packaging and cover with foil. If you don’t have any aluminum foil lying around, don’t worry! 

You can use a piece of parchment paper—the same stuff that comes in the box with frozen pizzas—and it’ll work just fine.

Just make sure that it’s big enough to wrap around your fish filet or fillets entirely. 

The best way to do this is by placing the fish in the middle of the parchment paper. 

Then, wrap both ends over the top before folding them underneath themselves and crimping them into place at each end.

Best Way To Reheat Salmon: Place On A Baking Sheet Or Pan

Baking Sheet for Reheating Salmon

Once your fish is wrapped up tight like a little package full of goodness, put it on an oven-safe baking sheet or cake pan. 

That way, it doesn’t touch anything while cooking in case there are some splatters during the heating time. 

It’s the best way to reheat salmon without destroying its taste. 

Preheat your oven to 350°F. Set the timer for 10 minutes and place the salmon in the oven on a baking tray lined with foil or parchment paper. 

Remove when done, serve warm, and enjoy!

How To Reheat Salmon In Using The Air Fryer Method


Using the Air Fryer is the best way to reheat salmon. It makes the salmon have a crisp baked surface while still being warm and delicate.

And if you’re in a pinch for time, this method is faster than the oven.

Placing salmon in an Air Fryer with the skin side down and preheating to 360°F is a great way to reheat this fish. 

Remember to line it with parchment to keep the skin from sticking. Warm the fish in the oven for 5 minutes.

Make sure your fillet reaches an internal temperature of 125°F, before serving by inserting a thermometer.

How To Reheat Salmon Using A Skillet Or Pan 


If you don’t have a non-stick pan, spray your pan with cooking spray to ensure that the salmon will easily slide out. You can use any type of non-stick spray (butter or oil would work, too). 

Just make sure you don’t use any butter or oil for this method.

Heat the cooking pan on medium heat and add one tablespoon of butter or olive oil. 

When it’s hot, place the salmon fillet in the pan and cook for 3 minutes. Then, you can flip over and cook another 3 minutes on the other side.

Put The Salmon Skin-Side Down in The Pan. 

Once the pan is on medium-low heat, place the salmon filet skin side down. Cook for about 5 minutes until an orange color develops on your fish’s surface. 

Don’t flip your salmon yet! 

At this point, turn off the stove and move your fish to a plate or cutting board with a spatula or tongs. Let it rest while you make some vegetables or rice to serve alongside it.

Don’t worry if some skin sticks to your pan—it’ll come right off after soaking in cold water.

How To Reheat Salmon: Tips For Reheating Salmon In The Pan

  • Use a thermometer to check the temperature of your cooked salmon. Aim for a temperature of around 105 degrees Fahrenheit. If you don’t have a thermometer, cook for about three to four minutes.
  • Don’t overcook your fish! This can be tricky because it’s hard to know exactly how much heat is needed and when each piece will finish cooking in the pan. A thermometer is the best tool for this.
  • When reheating salmon, don’t use high heat settings on your stovetop (or any other heating source). That’s because it can make it dry out more quickly than necessary. Also, ensure that whatever source you use won’t burn the cooked food. This includes non-stick pans, which may react with certain foods and cause them to become toxic at high temperatures.

You should be careful not to overcook delicate fish like salmon by using low heat and covering them with a lid. Overcooking will cause the fish to dry, so don’t leave it in the oven for too long. 

How To Reheat Salmon Using The Microwave 


Microwaving salmon isn’t the best way to reheat it, but it’s the quickest.

Even though the microwave can quickly reheat leftovers, it can also dry out fish if you aren’t careful. So you need to take additional measures to prevent that from happening. 

Covering the fish and adding extra liquid to the microwave-safe container can help it stay moist and tender during cooking.

Reheating salmon in the microwave requires only a tablespoon of liquid, lemon juice, water, or sauce and a microwave-safe plate. Wrap the salmon in plastic and heat it in the microwave for 30 seconds at a time.

You can also reheat the fish and vegetables together. The salmon is kept from drying out thanks to the moisture in the vegetables.

Should You Reheat Salmon? 

Some think fish loses quality when you reheat salmon in oven or other reheating methods. Other people avoid reheating seafood altogether out of safety concerns. 

First, the salmon’s overall quality will indeed dip a little. It won’t have the same flavor as when fresh from the grill. 

But, with careful reheating, the salmon can take on an almost identical flavor to that of freshly caught fish.

Second, reheating fish raises several valid health and safety concerns. For example, the Food and Drug Administration (FDA) warns that bacteria can multiply rapidly in seafood at room temperature. 

These bacteria may survive re-heating, leaving you vulnerable to food-borne illness.

It Takes An Hour For Salmon To Get Contaminated

The salmon will get contaminated in as little as an hour if left in temps above 90 degrees. Once this time has elapsed, the safety of the salmon can’t be guaranteed by reheating. 

So it’s best to throw them away. 

It’s best to promptly wrap up any leftover salmon and store it in the fridge after dinner. Doing so will increase the fish’s shelf life when stored.

Don’t try to chill it if it’s been sitting at room temperature for too long. The common idea that bacteria can be killed or their toxins neutralized by refrigeration is false. 

Nothing can be done besides discarding the entire salmon if bacteria has already spoiled it.


If you want to reheat salmon, these ways can help you do that. We hope you enjoyed learning about all the different ways to reheat salmon. 

Remember, there are many options for cooking salmon. Of course, you can reheat salmon in the oven, but you can also try other methods. 

Microwaving the salmon isn’t the best choice, but it’s the quickest. But that shouldn’t be a problem if you know how to do it. 

We encourage you to try these methods at home and see which works best for your family.
