Why Air Fryer Is the Best Way to Reheat Fish?

Retains the Original Texture

Reheating fish can be a tricky task, as it often turns out dry and overcooked. However, reheating fish in an air fryer is a game-changer, as it helps to retain the original texture of the fish. The circulating hot air in the air fryer ensures that the fish is evenly heated from all sides, which keeps it moist and juicy.

“By cooking food with rapidly circulating hot air, created by a top-mounted fan, air fryers produce a crispy exterior without the need for excess oil, making them a healthier option for frying.”

Whether you have leftover grilled or baked fish, the air fryer works wonders to keep your fish tasting just like freshly cooked. Simply preheat the air fryer at 350°F for 5 minutes, then place the fish inside and cook for 3-4 minutes on each side, depending on the thickness of the fish fillets.

Healthier Option

In addition to retaining the original texture of the fish, reheating fish in an air fryer is also a much healthier option compared to traditional methods such as pan-frying or microwaving. As mentioned earlier, air fryers use rapid circulation of hot air to cook the food, resulting in a crispy exterior without the need for excess oil.

When we reheat fish using traditional methods such as pan-frying, it usually requires additional oil to prevent sticking and drying out the fish. This added oil can significantly increase the calorie content of the dish. In contrast, reheating fish in an air fryer uses little to no oil, hence cutting down on calories and fat intake.

“Air-fried foods have a lower fat content than deep fried foods, which can cut down on calories.” -Harvard Health Publishing

Quick and Easy

The air fryer is an excellent kitchen gadget that saves both time and energy. Reheating fish in the air fryer is no exception. It is indeed quick and easy. Unlike reheating food on the stovetop or oven, the air fryer requires little to no preheat time, hence making it ideal for busy weeknights when you want to reheat something quickly without much effort.

When using an air fryer to reheat fish, there’s also no need for constant monitoring or flipping like traditional methods required. Simply place the fish inside the air fryer basket, turn on the machine, and let the hot circulating air do the magic. You’ll appreciate how the process is hassle-free, leaving you with plenty of free time.

“An Airfryer could be just what you’ve been looking for as it allows you to cook food up to three times faster while still being healthy with less oil usage than traditional frying methods.”

No Need for Additional Oil

If you’re fond of consuming fish but are worried about maintaining health goals, it’s best to reheat leftovers in an air fryer that doesn’t require additional oil. Fish soaks up added oils, leading to higher calorie intake and more unhealthy effects in your diet. The fantastic thing about air fryers is that they don’t require any extra oil to crisp up the fillet. Your food comes out golden brown, with no excess grease or calories associated with it.

Listed below are some essential tips to maintain the crispy texture of your reheated fish:

  • Place the fish at the bottom of your air fryer basket to avoid it from blowing around.
  • Preheat your air fryer for a minimum of 5 minutes before thawing frozen fish or reheating leftovers.
  • Set your timer and flip your fillets halfway through cooking, especially when you’ve got thick cuts like salmon or cod pieces.
  • If reheating battered fish, avoid overloading the basket with too many pieces. This will prevent the hot air from circulating correctly and delivering crispy results.

An air fryer is undoubtedly the best way to reheat fish. It retains the original texture of the fish, keeps it moist and juicy without any added oil, making it a healthy option for frying, reheats quickly and uniformly, resulting in crispiness without hassle.

What Type of Fish Can You Reheat in Air Fryer?

Cooked fish is a healthy and delicious meal for many people. However, when leftovers are kept in the fridge or freezer, they can quickly dry out and lose their flavor. Fortunately, an air fryer can be a great solution to reheat leftover fish while maintaining its moisture and texture. But not all types of fish are suitable for reheating in an air fryer. Let’s take a closer look at some of the best fish choices that can be easily reheated using this method.

White Fish

Whitefish is one of the most versatile types of fish, and it can be found in many different recipes around the world. Some popular whitefish species include cod, halibut, sole, and haddock. Whitefish has a delicate texture and mild flavor, which makes it perfect for various cooking techniques, including baking, steaming, grilling, and frying. When you plan to reheat your leftover whitefish in the air fryer, make sure to brush it with olive oil or melted butter to prevent drying out and enhance its flavor.

“Halibut works superbly in any cooking style—it’s especially nice grilled—or simply sautéed.” -Chef Michael Psilakis


Salmon is another very popular fish among seafood lovers due to its rich flavor and high nutritional value. This fatty fish is packed with omega-3 fatty acids, making it not only a tasty but also a heart-healthy addition to your diet. Salmon can be prepared in numerous ways, such as smoking, grilling, poaching, or broiling. It is important to note that salmon is quite oily, so when reheating it in the air fryer, be cautious not to overcook it as this can cause the fish to become too dry. If you prefer your salmon warm and crispy, brush it with a bit of oil or butter before placing it in the air fryer basket.

“For optimal flavor, opt for fresh wild-caught Alaskan salmon—it’s superior to farmed.” -Chef Brad Farmerie


If you are looking for a quick and easy fish meal, tilapia is an excellent choice. Tilapia has a mild flavor that pairs well with different spices and herbs, making it ideal for seasoning according to your taste preferences. Moreover, tilapia fillets are relatively thin, which means they cook quickly and evenly in the air fryer. Just like other types of fish, reheating tilapia in the air fryer requires some precautions. Before placing the fish in the basket, lightly coat it with oil or mayonnaise to avoid drying out and enable browning during the cooking process.

“Tilapia is light and flavorful, low in calories, and high in protein. It’s perfect for quick weeknight meals or fancy dinners.” -Cooking Light
  • If you want to achieve perfectly reheated fish with an air fryer, here are some additional tips:

  • Preheat your air fryer to the recommended temperature and time indicated by the manufacturer beforehand;

  • Spray or grease the air fryer basket lightly before placing the fish to prevent sticking;

  • Cover the leftover fish loosely with foil to help retain moisture while reheating;

  • Avoid overcrowding the basket by making sure each piece of fish is spaced apart so that the hot air can circulate around them evenly;

  • Check the fish temperature regularly to avoid overcooking and dryness. The internal temperature should be at least 145°F to ensure it is heated thoroughly.

Reheating fish in an air fryer can be a practical and tasty way to turn your leftovers into a new meal that tastes almost as good as the original dish. By following the tips mentioned above and choosing the right type of fish, you can make sure your reheated fish comes out moist, flavorful, and perfectly cooked with every use of your air fryer!

How Long to Reheat Fish in Air Fryer?

If you have leftovers from your fish dinner last night, no worries! You can reheat it the next day and enjoy its flavor once again. One of the best ways to reheat fish is using an air fryer. But how long does it take to do so? Here’s everything you need to know:

3-4 minutes for Thin Fillets

If you have thin fillets, such as tilapia or sole, they will reheat quickly in an air fryer. Preheat the appliance to 350°F and place the fish in the basket. Cook it for about 3-4 minutes, or until it is heated through. Avoid overcooking it, as this can dry out the fish.

Dietitian Kristin Kirkpatrick suggests that reheating fish should be done within two days after preparing it, otherwise microbes can start to grow, which may cause food poisoning.

5-6 minutes for Thick Fillets

For thicker fillets, like salmon or tuna, slightly more time is required. It’s recommended you preheat the air fryer to 400°F and cook for around 5-6 minutes. If the fillet was previously refrigerated, let it sit at room temperature for a little while before cooking to ensure even heating.

“Fish doesn’t keep well,” says Bonnie Taub-Dix, a registered dietitian nutritionist. “It’s important to always keep cooked protein chilled below 41 degrees Fahrenheit because bacteria grows between 40 and 140 degrees Fahrenheit.”

Reheating fish using an air fryer is quick and easy, but timing varies based on the thickness of the fillet. By following these tips, you’ll be able to enjoy the delicious taste of fish without it becoming overcooked or dry.

What Temperature to Reheat Fish in Air Fryer?

If you’re looking for a quick and easy way to reheat your leftover fish without losing its delicious flavor and texture, an air fryer might be the perfect solution. Air frying is a healthier alternative to deep frying that cooks your food with hot air, creating a crispy outer layer while keeping the inside moist and tender.

Not all fish are created equal, and different types of fillets require different temperatures and cooking times to reheat properly. Here are some guidelines on how to reheat fish in an air fryer:

350°F for Thin Fillets

If you have thin fillets such as tilapia, catfish, or trout, it’s recommended to reheat them at around 350°F. Preheat your air fryer for a few minutes, then place your fish fillets in a single layer in the basket. Cook for about 5-7 minutes, depending on the thickness of your fillets, until they reach an internal temperature of 165°F. You can also lightly coat the fillets with oil or butter to prevent sticking and enhance their flavor.

375°F for Thick Fillets

For thicker fish fillets such as salmon, cod, or halibut, you’ll need to raise the temperature slightly to around 375°F. This will ensure that the outside gets crispy without overcooking the inside. Again, preheat your air fryer for a few minutes and arrange your fillets in a single layer in the basket. Depending on the size and thickness of your fillets, cook them for approximately 8-10 minutes until they’re fully heated through and the internal temperature is 165°F.

400°F for Extra Crispy Texture

If you prefer your fish fillets to have an extra crispy texture, you can bump up the temperature to 400°F. This works best for thicker and denser fish such as swordfish, tuna, or mahi-mahi. Preheat your air fryer for a few minutes and place your fillets in a single layer. Cook them for about 10-12 minutes until they’re golden brown and crunchy on the outside while still juicy and tender inside.

Lower Temperatures for Delicate Fish (e.g. 325°F for Sole)

Some delicate types of fish like sole, flounder, or haddock may require lower temperatures and shorter cooking times to avoid drying out or falling apart. It’s best to reheat these types of fish at around 325°F for a few minutes, keeping a close eye on them to prevent burning or sticking. You can use a light coating of flour or bread crumbs to help them retain their shape and moisture.

“Fish is the only food that is considered spoiled once it smells like what it is.” -P.J. O’Rourke

Reheating fish in an air fryer is a convenient and healthy way to enjoy your leftover seafood without sacrificing flavor or quality. By adjusting the temperature and time according to the type and thickness of your fish, you can create a delicious and crispy dish in just a few minutes. Keep in mind that overcooking or undercooking your fish can result in dryness, toughness, or mushiness, so make sure to use a meat thermometer to check the internal temperature and adjust your settings accordingly.

How to Keep Your Reheated Fish Moist and Crispy in Air Fryer?

Use a Light Coating of Oil

When reheating fish in an air fryer, one key tip is to use a light coating of oil. This will help to keep your fish moist during the cooking process. You can either brush the fish with a small amount of oil or spray it with cooking spray before placing it in the basket of the air fryer.

It’s important not to overdo it on the oil. Using too much oil can actually make your fish greasy rather than helping it stay moist, so be sure to apply it sparingly.

Preheat Air Fryer for 3-5 Minutes

Another essential step to keeping your reheated fish moist and crispy in an air fryer is to preheat the device properly. Preheating helps to ensure that your food cooks evenly and avoids any potential hot spots.

You should preheat your air fryer for approximately 3-5 minutes before adding the fish. If you skip this step, the temperature inside the air fryer may fluctuate and lead to uneven cooking or even undercooked food.

Place Fish in a Single Layer

When reheating fish in an air fryer, it’s best to spread it out in a single layer. Overcrowding the basket can cause the fish to steam instead of getting crispy.

If you have a large amount of fish to reheat, do it in batches rather than trying to cook them all at once. Placing your fish in a single layer ensures maximum airflow, which allows the hot air to circulate freely around each piece and crisp up the exterior.

Use a Cooking Spray to Avoid Sticking

One common problem when reheating fish in an air fryer is that it can stick to the basket, making it difficult to remove and potentially causing the coating to peel off.

You can avoid this issue by using cooking spray on the bottom of the basket before adding the fish. This will create a non-stick surface and prevent your fish from sticking to the basket. Additionally, you can flip the fish halfway through the cooking process to ensure both sides are crispy.

“Preheating helps to ensure that your food cooks evenly and avoids any potential hot spots.” -Nina Olsson

With these tips in mind, you should be able to successfully reheat your leftover fish in an air fryer with moist, crispy results. Remember to use a light coating of oil, preheat the device properly, place the fish in a single layer, and use cooking spray to avoid sticking for the best outcome. Enjoy!
