Salmon is one of the most popular types of fish, thanks to its rich flavor and numerous health benefits. It’s also easy to cook, which makes it a go-to choice for weeknight dinners. But what happens when you have leftover salmon? Can you reheat it in an air fryer? Yes, you can!

Frozen Fish Sticks

Frozen fish sticks are a popular option for quick and easy meals. They’re a hit with kids and adults alike and can be ready in minutes. But what happens when you have leftover fish sticks? Can you reheat them in an air fryer? Yes, you can!
To reheat frozen fish sticks in an air fryer, preheat the air fryer to 400°F. Then, place the fish sticks in the air fryer basket and cook them for 6-8 minutes, flipping them halfway through.
Preparing the Fish for Reheating
Thawing the frozen fish (if necessary)
If you’re planning to reheat frozen fish, the first step is to thaw it properly. To thaw frozen fish, you can either leave it in the fridge overnight or use the defrost setting on your microwave.
Once the fish is thawed, pat it dry with a paper towel to remove any excess moisture.
Adding seasoning or sauces to enhance the flavor
To add more flavor to your grilled fish, you can season it with your favorite herbs and spices. Some popular seasonings for fish include lemon pepper, garlic, and dill. You can also add sauces such as tartar sauce or aioli to enhance the flavor. When seasoning or saucing your fish, make sure to spread the seasonings or sauces evenly on both sides of the fish.
As a personal experience, I found that adding a bit of olive oil to the fish before reheating it in the air fryer can help enhance its flavor and texture. Additionally, make sure to choose the right seasoning or sauce that complements the type of fish you’re reheating. For instance, a lemon-dill seasoning works well with salmon, while a garlic-butter sauce pairs well with white fish fillets.
Research shows that seasoning and sauces can significantly enhance the flavor and nutritional value of fish. A study published in the Journal of Food Science found that seasoning fish with herbs and spices increased its antioxidant activity and improved its overall taste. Additionally, adding healthy fats such as olive oil can also improve the nutritional profile of fish.
How to Reheat Grilled Fish in Air Fryer (Step by Step)
STEP 1:
Preheating the air fryer is crucial to ensuring that your grilled fish is cooked evenly and thoroughly. To preheat the air fryer, set the temperature to 375°F (190°C) and let it run for 5 minutes.
STEP 2:
Place the grilled fish in the air fryer basket. If the fish is too large to fit in the basket, you can cut it into smaller pieces.
STEP 3:
Set the timer for 5-7 minutes, depending on the thickness of the fish. If you’re reheating frozen fish sticks, set the timer for 10-12 minutes.
STEP 4:
Flip the fish over halfway through the cooking process to ensure even heating.
STEP 5:
Check the internal temperature of the fish with a meat thermometer. The FDA recommends a minimum internal temperature of 145°F for fish.
STEP 6:
Once the fish is fully reheated and cooked to the desired temperature, remove it from the air fryer and let it cool for a few minutes before serving.
Adding a little seasoning or sauce to the fish before reheating can enhance its flavor. However, be careful not to add too much sauce, as it can make the fish soggy. It’s also important to thaw frozen fish before reheating it in the air fryer, as it will cook more evenly.

Tips for Achieving the Best Results
- Do not overcrowd the air fryer basket. If you put too much fish in the basket, it will not cook evenly, and the end result will not be as crispy.
- Keep an eye on the fish as it cooks.
- Flip the fish halfway through the cooking time.
- Adjust the cooking time and temperature depending on the type of fish and the thickness of the fillets. Thicker fillets will require more cooking time, while thinner fillets will cook faster.
- Consider using a cooking spray to help the fish become more crispy.
- Add some lemon juice or your favorite seasoning to the fish before reheating to enhance the flavor.
- Preheat the air fryer before adding the fish to ensure that it cooks evenly.
- For frozen fish sticks, do not thaw them before reheating. Simply add them to the air fryer and adjust the cooking time accordingly.
- Allow the fish to cool for a few minutes before serving to prevent it from being too hot.
