Preheat the air fryer to 400°F.

Brush the tilapia filets with olive oil and lemon juice on both sides.

Sprinkle half the garlic powder, salt, pepper, and paprika on top of the fish. Repeat on the other side of the tilapia.

Place two filets in a single layer in the basket of the air fryer and cook for 12 minutes, flipping the fish halfway through the cooking time.

After flipping the filets, top with half the parmesan cheese and continue cooking until they are golden, tender, and flaky.

Repeat with the two remaining filets. (You can cook as many fish filets as fit in your air fryer basket.)

Garnish the filets with lemon wedges and serve with your favorite side dish.
