The good news is there are several approaches to reheating fish, so the trick is simply to find which method is best. 

Can You Reheat Fish? 

While it is possible to reheat fish, this dish is one that can be reheated to disastrous effects. The truth is you can reheat pretty much any food that has been refrigerated or frozen.  

Can You Reheat Fish?

The question is whether you can reheat it in a way that returns it to its original state– the flavors, the aromas, even its appearance. Or at least something close to its original state. 

It all comes down to approach. Some foods are better reheated in the oven or an air fryer, like breaded or deep-fried foods. Other foods are well-served by a grill reheat, like baked or grilled dishes. 

For fish, the best approach is likely going to be a grill or an air fryer and much less likely to be the microwave. 

Should You Reheat Fish? 

But we’re talking about fish here. Never mind can you reheat fish, should you reheat fish? 

We hear all the time about the dangers of poor preparation of fish. Does reheating pose the same issues? 

The goal of this article, of course, is to provide you with some tips for reheating fish. But it’s always a good idea to do your own research as to whether you should be reheating this particular food.  You can get started with this article by the US Sun that reports it to be perfectly safe. 

How to Reheat Fish in the Oven 

Reheating fish in the oven is probably one of the best approaches. It takes a little bit longer than the other ways, but it almost guarantees your fish will maintain its moisture. 

  1. Place your fish fillets on a wire rack set on a rimmed baking sheet. 
  2. Cover the entire baking sheet with aluminum foil and tuck the foil around the edges of your pan. The goal here is to prevent your fish from drying out in the hot oven. 
  3. Warm your fish in the oven at 275 degrees Fahrenheit.  
  4. After 15 minutes, check the temperature of your fish to be sure it has reached between 125 to 130 degrees Fahrenheit. 
  5. If the fish is still too cool, allow it to heat for another 5 minutes and check again. 
  6. Serve and enjoy! 

How to Reheat Fish in the Microwave 

Microwaves are not the best option for reheating fish as they can easily overcook it, leaving it rubbery. However, if a microwave is your only option, follow these steps: 

  1. Place your fish in a microwave-safe dish with a microwave-safe cover. Remember, we want to retain as much moisture as we can. 
  2. Set your microwave to low power, 30-40% should be good. 
  3. Microwave your fish in 30-second intervals until it is heated all the way through. These short bursts will allow you to check on your fish before it dries out. You can also flip the fish every time you check on it to ensure it heats all the way through. 

How to Reheat Fish in an Air Fryer 

Another favorite approach is reheating fish in an air fryer. 

  1. Set your air fryer to the reheat setting. Your temperature should be between 325-350 degrees Fahrenheit. 
  2. Set your timer for 7 minutes. 
  3. Spray your fish fillets with olive oil to help them retain moisture. 
  4. Place the fish in your air fryer basket or tray for 4 minutes, ensuring you allow space between your fillets. 
  5. Flip the fish.  
  6. Allow the fillets to sit in the air fryer for another 3 minutes. 
  7. Serve and enjoy. 

How to Reheat Fish on a Grill 

Reheating fish on a grill can be super convenient if you’re already grilling. Remember, the goal here is to cook it low and slow. On your grill that means cooking it over low indirect heat. 

  1. Wrap each individual fillet loosely in aluminum foil. This will allow the steam created during cooking to be trapped in the foil and help your fish stay moist. 
  2. Place the wrapped fish on the grill over indirect heat. 
  3. Just like in the oven, you’ll want to give your fish 15-20 minutes, checking it for that internal temperature of 125-130 degrees Fahrenheit. 

How to Reheat Fish in a Toaster Oven 

Oh, the toaster oven. The go-to appliance for college students and young people out on their own for the first time. 

The toaster oven can actually be a great way to reheat fish as it provides gentle, even heating. 

Like with the grill, wrap your individual fillets in aluminum foil to trap any steam created. 

Set the toaster oven between 275 and 350 degrees Fahrenheit but no higher. 

Because this appliance is smaller and more compact, you’re going to want to check on your fish after 10 minutes and then every 2-3 minutes after that, inserting your thermometer each time until you observe the 125 degrees Fahrenheit internal temperature. 

How to Reheat Fish in a Pan on the Stove 

Realize that if you want to reheat fish in a pan on the stove, you will get a bit of a fishy smell. The smell is totally normal and does not necessarily mean that your fish has gone bad. 

How To Reheat Fish in a Pan on the Stove

Place a skillet on the stove on low heat.  

Add olive oil to the bottom of your pan just to cover the surface. 

Once the oil has heated in your pan, add your fish fillets, allowing space in between them, and cover the skillet. 

Check on your fish every 3 minutes to be sure it is heating thoroughly, but only flip every 6 minutes or so to prevent your fish from getting flaky. 

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

And now for the winner! 

The best way to reheat fish is using the oven. Yes, it is the longest wait, but the wait is worth it. 

It is the best way to slowly heat up your fish from the inside out while also maintaining its moisture.
