If you love seafood, then there’s no better way to enjoy it than fresh off the grill or out of the frying pan. However, if you’ve got some leftovers lying around, reheating fish can be a daunting task – especially without ending up with dry and overcooked fish.

The good news is that reheat fish in oven is one of the easiest ways to go about it. Whether you’re dealing with fillets, steaks, or whole fish, it takes minimal effort, and with these simple tips, you’ll have your fish reheated perfectly every time.

“You don’t want your lips to touch water when eating a piece of grilled fish, but neither do you want to choke on something too dry. Following the right reheating techniques are key to preserving the delicate flavour profile” says famous chef Rick Stein

There are several approaches to warming up fish in the oven, depending on what kind of texture and finish you prefer. You could bake it, broil it, or even use foil to create a makeshift “steamer.” With each method having its own advantages and disadvantages, understanding how they work will help you pick which one suits the type of fish you’re reheating best.

So, whether you’re working with freshly cooked salmon, cod, trout, tuna, or any other type of fish, we’ve got you covered with this guide on how to reheat fish in oven so that you don’t need to worry about wastage or ruining your delicious meal again!

Preheat Your Oven

When it comes to reheating fish in the oven, preheating your oven is an essential step. This not only helps with cooking the fish evenly, but it also ensures that the fish stays tender and moist.

Set The Temperature

The temperature at which you should set your oven largely depends on the type of fish you are reheating. In general, most types of fish can be reheated between 325-350 degrees Fahrenheit.

“Reheat baked or broiled fish fillets by setting them inside foil packets and placing them in a 350-degree oven until hot. Reheat breaded fish fillets by putting them on a wire rack and placing this inside a baking sheet lined with foil. Heat at 375 degrees F for five minutes or until crispy.” -Kristie Collado

For delicate fish such as salmon or trout, lower temperatures may be preferred to prevent overcooking. Similarly, if you are reheating a larger piece of fish, it may require a slightly lower temperature and longer cooking time than smaller pieces.

Wait For The Oven To Reach The Desired Temperature

A common mistake when reheating fish in the oven is not allowing the oven to properly preheat. It’s important to wait until the oven reaches the desired temperature before placing the fish inside.

“If the oven isn’t hot enough, fish will cook unevenly and won’t reach the right internal temperature,” according to Good Housekeeping’s food experts.

This can result in unevenly cooked fish that’s dry on the outside and cold on the inside.

Prepare The Baking Sheet

To prevent the fish from sticking to the baking sheet and ensure even cooking, it’s important to prepare the baking sheet properly. One option is to lightly coat the baking sheet with cooking spray or oil.

Another popular method is to line the baking sheet with parchment paper, which not only prevents sticking but also helps with easy cleanup afterwards.

“Place the fish on a greased baking tray (or onto some grease-proof paper on top of your oven tray). Make sure the pieces aren’t touching each other so that they cook evenly.” -BBC Good Food

When placing the fish on the baking sheet, ensure that there is enough space between each piece to prevent overcrowding and allow for even cooking.


Reheating fish in the oven can be a quick and easy way to enjoy leftovers without sacrificing taste or texture. By following these simple steps to preheat your oven, set the right temperature, allow the oven to reach the desired temperature, and prepare the baking sheet properly, you’ll be able to enjoy perfectly cooked and deliciously tender fish every time!

Wrap The Fish In Foil

If you want to reheat fish in the oven, wrapping it in foil is one of the best options. This method will keep your fish moist while maintaining its texture and flavor. Here’s how:

Choose The Right Type Of Foil

The first step in wrapping fish in foil is choosing the right type of foil. You can use either regular aluminum foil or heavy-duty aluminum foil. Heavy-duty foil is thicker and more durable than regular foil, which makes it ideal for larger pieces of fish. However, if you don’t have heavy-duty foil on hand, regular foil will do just fine.

Make sure that the entire piece of fish is covered with the foil, leaving no room for air to escape. This will help retain moisture and protect the fish from burning.

Season The Fish Before Wrapping

Before wrapping the fish in foil, season with salt, pepper, butter, herbs, or any seasoning of your choice. Adding lemon slices also helps to enhance the flavor. This step is essential as seasoning will lock in the flavors releasing a rich aroma during the reheating process.

Note: If using dry heat as an option, make sure to drizzle oil all over the fish before adding the seasoning evenly.

You can also add some vegetables like tomatoes, onions, garlic, zucchini, etc., to complement the dish. Place the seasoned fish in the center of the foil, then fold up the sides of the foil tightly to create a sealed pouch.

“We recommend checking the temperature (145 degrees F) at the thickest part of the food being served to guarantee safe consumption.” -USDA

Place the wrapped fish onto a baking sheet or pan, depending on the size of your fish. It is always suggested to use a baking pan instead of an oven rack to avoid any direct heat contact preventing burning.

Reheat in a pre-heated 350 degrees Fahrenheit oven for 10-15 minutes or until the internal temperature reaches 145°F. You don’t need to flip the fish during reheating, but you can do so halfway through if desired. Check ongoingly and when done remove the fish from the foil pouch, serve with vegetables and enjoy!

“When it comes to reheating cooked fish, whether it be previously grilled salmon or shrimp scampi, once again, thorough heating to at least 145˚F is key.” -Erika Giovanetti

Wrapping fish in foil before reheating in the oven is an excellent way to preserve its moisture and retain its flavors. Ensure to choose the right type of foil, season appropriately, and reheat thoroughly using correct cooking temperatures to prevent bacterial growth that could cause food poisoning.

Place The Fish On A Baking Sheet

If you’re looking to reheat your leftover fish, the oven is a great option. It’s efficient and can keep your fish tasting delicious if done correctly. Preheat your oven to 275°F and line a baking sheet with aluminum foil. Then, place your leftover fish on the baking sheet.

It’s important that you don’t overcrowd the baking sheet. Make sure there is space between each piece of fish, so they heat evenly. If you have multiple pieces of fish, try to arrange them in one layer rather than stacking them on top of each other. This will ensure that each piece is heated thoroughly.

Arrange The Fish Evenly

To make sure each piece of fish heats evenly, arranged it slightly apart from each other. Use a fork or spatula to flake any large pieces into smaller sections. Avoid leaving any single portion too large as it can increase your cook time and affect the taste of the dish.

You should take care not to squish the fish so much that it falls apart when curling up. Additionally, ensure that no bones are sticking out, as this could cause issues while heating, resulting in dry uneven cooked fish.

Add Vegetables And Herbs For Flavor

The key to adding flavor back into reheated fish is using herbs and vegetables. After placing your fish on the baking sheet, add some veggies like mushrooms and breadcrumbs sautéed together for additional texture and moisture. Add little sprigs of thyme or basil along with finely chopped garlic before placing the fish lay over the veggie mix.

In essence, the idea here is to create an aromatic infusion to counteract the added blandness created by the refrigeration process. Allowing herbs to do their work can make your fish taste as if you had made your dish afresh.

Drizzle With Olive Oil

Add a drizzle of olive oil over the top of the fish, ensuring that it covers each piece. Olive oil will help keep the fish moist and prevent it from drying out during the reheating process. If you don’t have any other flavors or vegetables, extra-virgin olive oil is a simple way to add additional herby notes.

This also helps create a layer between the fishpiece t like when prepared freshly; this makes for an excellent texture, making it easier to reintroduce delicate items back into meals.

“The right oil can bring out the hidden flavours in different types of fish not featured before.” -Gioia Caputi

Once the fish has been arranged on the baking sheet with its seasoning oven-top, place it in the preheated oven. Let the fish heat up for approximately 15 minutes or until thoroughly cooked through. After taking it out, you would notice the food becoming less bland and more flavorful by following these steps.

You may decide to use a meat thermometer to confirm whether your fish’s internal temperature has attained the proper range of 135-140°F, which ensures that all bacteria are obliterated upon consumption.

To season again once properly heated, sprinkle salt across the tray (not only the surface of the fish), then serve immediately alongside your preferred side dishes with some lemon slices on your plate.

Reheating fish leftovers doesn’t just give them a second chance at being consumed; it allows someone to enjoy many benefits accompanying well-preserved food. Additionally, implementing the advice given assures one eating healthy food while saving money embodied memories.

Reheat The Fish For The Right Amount Of Time

Fish is a delicate protein, and reheating it can be tricky. If you overcook the fish, it will become dry, rubbery, and unappetizing. On the other hand, if you undercook the fish, it won’t be safe to eat. Here’s how to reheat fish in the oven:

  • Preheat your oven to 350°F.
  • Take the leftover fish out of the fridge and let it come to room temperature for about 10-15 minutes. This will prevent the fish from becoming too cold on the inside while the outside cooks.
  • Wrap the fish in aluminum foil or place it in an oven-safe dish with a tight-fitting lid to help keep moisture in while cooking.
  • Place the wrapped fish or covered dish in the oven.
  • The amount of time that the fish needs to heat depends on its thickness. A general rule of thumb is to reheat fish for 10-15 minutes, but thicker cuts may need more time.

Use A Meat Thermometer To Check The Temperature

It’s important to make sure that the fish reaches an internal temperature of at least 145°F before consuming it. Use a meat thermometer to check the temperature at the thickest part of the fish.

  • If the fish has reached an internal temperature of 145°F, take it out of the oven immediately.
  • If the fish hasn’t reached the optimal temperature yet, put it back in the oven and continue reheating for a few more minutes. Be sure to check the temperature often to avoid overcooking the fish.

Using a meat thermometer is the most accurate way to ensure that the fish is fully cooked through while still maintaining its moisture and texture.

Remove The Foil During The Last Few Minutes Of Cooking

If you wrapped the fish in foil, it’s a good idea to remove the foil during the last few minutes of cooking. This will allow the fish to brown slightly on top and create a crispy crust that is delicious and visually appealing.

Be sure to keep a close eye on the fish during this process to avoid overcooking or burning it.

Let The Fish Rest Before Serving

After taking the fish out of the oven, let it rest for a few minutes before serving. This allows the juices within the fish to redistribute, making the flesh tender and juicy throughout.

If you cut into the fish right away, the juices will run out onto your plate, leaving the fish dry and flavorless.

“Reheating leftover fish may not sound appetizing if you’ve ever had a fishy-tasting dish, but it can be done without sacrificing taste or quality.” -Eat This, Not That!

With these tips, you’ll know how to reheat fish in the oven so that it comes out perfectly every time. Bon appétit!

Serve The Fish Immediately

If you want to know how to reheat fish in the oven, it’s important to remember that timing is everything when it comes to serving this tasty dish. Most people prefer their reheated fish served immediately so that it tastes as fresh and delicious as possible. Allow the fish to cool down slightly before covering it with aluminum foil or parchment paper and placing it in the oven for the reheating process.

You can check whether your fish is ready by sticking a fork into its thickest part and gently twisting it. If the flesh flakes easily and looks opaque, then it’s good to go! Take it out of the oven and serve it right away while it’s still hot and flavorful.

Plate The Fish Nicely

Once your fish has finished reheating in the oven, it’s time to plate and present it nicely to impress your guests. Start by placing the carefully heated servings on clean plates, making sure that each serving is about the same size and shape.

You can also add some color and variety to the dish by decorating the top of the fish with chopped parsley, basil, or coriander leaves. This not only enhances the look but also adds an extra layer of flavor to the dish!

Garnish With Lemon Wedges

To take things up a notch, consider adding lemon wedges as a garnish for your reheated fish dish. Not only do they provide a refreshing citrusy flavor that pairs well with most types of fish, but they also make the dish look more appealing.

“Lemon juice applied directly onto fish is one of the best ways to change a bland piece of fish into something really appetizing.” -Curtis Stone

Squeeze the lemon wedge over the fish just before serving to give it a burst of citrusy flavor. You can also garnish each plate with additional lemon wedges for those who want an extra zing!

Accompany With A Side Dish

To complete your reheated fish meal, consider complementing it with a side dish that adds flavor and texture to the overall experience. This can be anything from rice pilaf to roasted vegetables or buttered potatoes.

If you’re looking for something light and refreshing, you can also serve some salad greens dressed in a simple vinaigrette on the side, which will cleanse your palate after enjoying the complex flavors of the reheated fish.

“I like to use fresh herbs like rosemary, thyme, and parsley to add extra layers of flavor to my side dishes.” -Ina Garten


The final step is to sit down and enjoy the delicious reheated fish served warm with its beautifully paired sides and garnishes. Every bite of tender flakes soaked in flavorful juices will be a true delight for seafood lovers! Remember always to store any leftover food properly in the refrigerator or freezer so that they last longer and stay fresh.

With these tips, now you know how to reheat fish in the oven confidently and safely while getting flawless results every time. Keep in mind that timing, plating, garnishing, pairing, are all integral parts of creating a memorable dining experience that leaves everyone feeling happy and satisfied.
