Can I Reheat Salmon? Tips on Which Method Is Best

While there may be some naysayers who claim that fish is never good the next day, the argument can be made that this view is impractical. The fact is, as delicious as salmon is, there will come a time when you won’t be able to eat it all, and there will be leftovers.

Rather than throw it away, it is possible to reheat your leftover salmon to enjoy another day. True, you can ruin salmon by reheating, but if you do it right, it can be just as good as it was the first time.  

Here are some tips on how to reheat salmon properly using a few different methods. 

Can You Reheat Salmon? 

As long as you’re willing to take some time with it, salmon can be reheated beautifully. But be patient.  


Can You Reheat Salmon

Low and slow is the key to retaining all the flavor and juiciness of your fish, but if you rush it, you will risk drying it out. 

Should You Reheat Salmon? 

Fish can be a tricky food when it comes to food safety because it is particularly prone to harmful bacteria when left at room temperature for any length of time. This is true of all meats, but even more so for fish.  

If your salmon was left out and you’re not sure if it’s safe to eat, then it should be discarded. 

It should also be noted that the reheating methods we share here will not raise the temperature of your salmon to the point of eradicating harmful bacteria. So, it’s important for you to be confident that your salmon is safe before reheating it. 

How to Reheat Salmon in the Oven 

The trick here is to keep it low and be patient. The oven can be your friend if you use it wisely. 

Heat your oven to 275 degrees Fahrenheit then find something to drizzle on your salmon to keep it from drying out.  

It’s okay to get creative here. Olive oil, lemon juice, or butter will help add and retain moisture during reheating.  

Loosely wrap your salmon in foil and place on a rimmed baking sheet. Bake for about 15 minutes, being careful not to overcook. 

How to Reheat Salmon in the Microwave 

The microwave is not ideal for reheating fish as it tends to pull moisture out of whatever it’s cooking. But if this is all you’ve got, it is possible to make it work.  

If you can, set your microwave to the low setting then cover your fish with a damp paper towel and heat for 30 seconds. Flip the fish over and cook for another 30 seconds.  

How to Reheat Salmon in an Air Fryer 

The air fryer does a great job of reheating food quickly. Your job is to make sure you take it out as soon as it’s done so it doesn’t overcook.  

Heat your air fryer to 350 degrees Fahrenheit for 5 minutes then place your salmon in the fryer basket and cook for 4-5 minutes until heated through.  

Just like with the oven method, feel free to add something to make your salmon moist and flavorful while it cooks, but this isn’t strictly necessary with this method. 

How to Reheat Salmon on a Grill 

While we don’t recommend this method as ideal for reheating salmon, it can be done, especially if you have a flat-top grill like a Blackstone or a cast iron griddle pan to place on your grill. Cooked salmon can be delicate and might fall right through the grate of a charcoal or gas grill.  

No matter how you do it, though, be sure to follow the cardinal rules of low and slow. Heat your grill or griddle to a medium-low heat.  

Drizzle your salmon with olive oil and lemon juice. Wrap it in foil if you can, especially if you’re putting it directly on the grill grate. Grill for 15 minutes until heated through. 

How to Reheat Salmon in a Toaster Oven 

If you have a toaster oven and a small amount of salmon to reheat, by all means make use of this handy contraption. The technique involved is the same as using the oven, but it takes less time to cook and doesn’t heat up the house.  

How To Reheat Salmon in a Toaster

Simply follow all the steps for the oven method but cook for 10 minutes rather than 15. 

How to Reheat Salmon in a Pan on the Stove 

If you’ve got a stovetop or hotplate and a skillet, and if you don’t want a lot of fuss, you can reheat your salmon in a pan. If your salmon happens to have some skin on it, so much the better.  

Melt plenty of butter over medium heat. Add your salmon and a little bit of water or stock and cover your skillet with a lid to trap the steam.  

Cook for 5 minutes, then remove from heat. If you do have some skin on your salmon, you can remove the liquid from your pan and cook a bit longer to get your skin crispy. 

WINNER – The Best Way to Reheat Salmon Is Using the Oven 

While it’s not the fastest or most convenient method, when used properly, the oven does the best job of reheating salmon so it’s tender and juicy. It also allows for the most flexibility and creativity for repurposing your salmon for other dishes. 

Whether it’s salmon steaks or filets, with skin or without, this fish is infinitely versatile as a next day dish.
