Air fryer frozen tilapia is super convenient and super delicious way to mix up a weeknight dinner! Tilapia filets are a great source of lean protein and can be extremely beneficial for anyone who is looking to build muscle or eat protein that promotes tissue repair. Rich in Omega-3 Fatty Acids, there are also major heart and brain function benefits as well. There is also less mercury compared to other fish like tuna. As a nutritionist, I believe this is a great alternative for women who are pregnant or families with younger children.
My recipe is seasoned with a zesty blend of spices and then air-fried to golden perfection in a matter of minutes. It's a quick, easy, and healthy main course everyone will love.

I love fish, and I love combining it with the ease of using an air fryer. Recipes like my air fryer salmon bites are always heavily featured in my rotation, and now I've added this frozen tilapia to the mix.
Using frozen tilapia filets makes it easy to whip this recipe up anytime, especially for meal prepping, and the air fryer cooks them quickly and easily without having to defrost them. I always love looking into the refrigerator and seeing a few containers of tilapia meal prep. This is a great backup plan when needing a bit on the go, or when you are tied of back-to-back days of chicken.

Flavor Variations
- Tilapia: Any white firm white fish like orange roughy, cod, red snapper, pollock, or catfish will work in place of tilapia.
- Mild: For a more subdued flavor, omit the Cajun seasoning.
- Extra Spicy: Add cayenne for a kick of heat.
- Lemon Olive Oil: If you don't have lemon olive oil, use the same amount of lemon olive oil and add 1 teaspoon of lemon juice.
Instructions
1: Combine all the seasonings in a small bowl. Then, wash the tilapia filets and pat them dry. Coat both sides of the filets with both olive oils. Then, evenly coat both sides of the filets with the seasonings.
2: Spray the air fryer basket with olive oil and add three fillets to it. Then, place the sliced green bell peppers on top.
3: Cook the tilapia at 395 until the internal temperature reaches 145 degrees with a food thermometer.
Hint
I find it easiest to check for doneness with my food thermometer. This ensures that my tilapia is moist and flaky without being undercooked and prevents dry, overcooked fish.
Storage
Refrigerate this tilapia for up to 3 days in an air-tight container.
To reheat the tilapia, microwave individual portions at 30-second intervals until heated through.
What to Serve with Air Fryer Frozen Tilapia Filets
Serve this tilapia with rice and a flavorful vegetable side like air fryer asparagus. You can also add it to pasta dishes like Marry Me pasta or put it in place of shrimp in this blackened shrimp alfredo recipe.
Expert Tips
- Don't defrost the tilapia. This recipe was designed to cook frozen fish. If you thaw the filets, adjust the cooking time.
- It's important to rinse and dry the fish so the olive oil and seasonings stick to it readily.
- Preheat your air fryer for even cooking and the best results. It only takes a couple of minutes.

FAQ
In general, you should preheat your air fryer. Preheating only takes a few minutes, and it ensures the food cooks evenly and consistently throughout.
Many white fish varieties can be used in place of tilapia. Fish like catfish, snapper, flounder, halibut, orange roughy, and cod all have a firm texture and mild flavor like tilapia.
With this recipe, you don't have to defrost your fish. However, if you do need to defrost fish, the safest way to defrost fish is overnight in the refrigerator. This ensures there is no bacteria growth as the fish defrosts. For quicker defrosting, place the fish in cold water. NEVER defrost fish in hot water.
