Prep time: 10 minutes
Cook time: 8 to 10 minutes
Total time: 18 to 20 minutes
What You’ll Need
- 4 tilapia fillets, about 6 ounces each
- 1 tablespoon olive oil
- 1 tablespoon melted butter
- 1 1/2 teaspoons Cajun seasoning
- 1/2 teaspoon garlic powder
- 1/2 teaspoon paprika
- 1/4 teaspoon onion powder
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon lemon juice
- 1 tablespoon chopped fresh parsley
- 1 lemon, cut into wedges

Tools Required
- Air fryer
- Small mixing bowl
- Measuring spoons
- Pastry brush or spoon
- Tongs
- Plate or tray
Pro Tips
- Pat the tilapia dry really well before seasoning. This helps the oil and spices stick better.
- Do not crowd the air fryer basket. Leave a little room around each fillet so the hot air can move.
- Check the fish early. Tilapia is thin, so it can go from perfect to overcooked pretty fast.
- Add the lemon juice after cooking for the freshest flavor.
- Use a little melted butter at the end for extra richness and shine.
Substitutions and Variations
- Swap tilapia with cod, catfish, or haddock. Just adjust the cook time if the fillets are thicker.
- Use blackening seasoning instead of Cajun seasoning for a slightly deeper flavor.
- Add a pinch of cayenne if you want more heat.
- Use avocado oil instead of olive oil.
- Finish with a little honey butter if you want a sweet and spicy twist.
Make Ahead Tips
You can mix the seasoning blend up to a week ahead and keep it in a small sealed container. You can also pat the tilapia dry and season it a few hours early, then refrigerate it until you are ready to cook.
Air Fryer Cajun Tilapia Recipe
Mixing the recipe and instructions together makes this easy to follow from start to finish.
Step 1: Preheat the air fryer and prep the fish
Preheat your air fryer to 400°F for about 3 minutes. While it heats, pat 4 tilapia fillets dry with paper towels and place them on a plate or tray. Dry fish seasons better and cooks up with a nicer texture.
Step 2: Make the Cajun seasoning mix
In a small bowl, stir together 1 1/2 teaspoons Cajun seasoning, 1/2 teaspoon garlic powder, 1/2 teaspoon paprika, 1/4 teaspoon onion powder, 1/4 teaspoon salt, and 1/4 teaspoon black pepper until evenly mixed.

Step 3: Coat the tilapia
Brush both sides of the 4 dried tilapia fillets with 1 tablespoon olive oil. Sprinkle the seasoning mix evenly over both sides of the fish, pressing gently so the spices stick. The fillets should look well coated but not heavily packed.

Step 4: Air fry the tilapia
Place the seasoned tilapia fillets in the air fryer basket in a single layer. Air fry at 400°F for 8 to 10 minutes, depending on thickness. The fish is done when it flakes easily with a fork and reaches 145°F in the center.

Step 5: Finish with butter, lemon, and parsley
Transfer the cooked tilapia to a round plate. Drizzle with 1 tablespoon melted butter, then sprinkle with 1 tablespoon chopped fresh parsley and 1 tablespoon lemon juice. Serve with lemon wedges on the side.

Why This Recipe Works (Quick Science)
Tilapia is a lean fish, which means it cooks quickly. The air fryer uses hot circulating air, so the outside gets lightly crisp while the inside stays tender. The olive oil helps the seasoning stick and helps the surface brown a little better. The melted butter added at the end brings back richness, while the lemon juice brightens the flavor and balances the spices.
Common Mistakes
- Not drying the fish first: Wet fish will not hold the seasoning as well.
- Overcooking the tilapia: Since tilapia is thin, it can dry out fast. Start checking around 8 minutes.
- Using too much salt: Cajun seasoning often already has salt, so keep that in mind.
- Crowding the basket: The fish cooks better when air can move around it.
- Adding lemon juice before cooking: This can make the texture less ideal and can wash off the seasoning.

Leftovers and Storage
Store leftover tilapia in an airtight container in the fridge for up to 2 days. Reheat in the air fryer at 350°F for 2 to 3 minutes or until warmed through. Try not to microwave it too long, or the fish can turn rubbery. Leftover tilapia is also great flaked into tacos, rice bowls, or salads.
FAQ
Can I use frozen tilapia?
Yes, but thaw it first and pat it very dry before seasoning. That helps the texture and flavor.
How do I know when tilapia is done?
It should flake easily with a fork and look opaque in the center. The internal temperature should reach 145°F.
Is this recipe very spicy?
It has a little kick, but it is not overly hot. You can reduce the Cajun seasoning or choose a mild blend if you want less heat.
Do I need to flip the fish?
Usually no, especially for thin fillets. If your air fryer runs hot on one side, you can gently flip halfway through.
Can I make this without butter?
Yes. The butter adds richness, but the recipe still works with just olive oil and lemon juice.
