Brush both sides of each fillet lightly with olive oil.
Mix the paprika, garlic powder, onion powder, salt, and black pepper, then season both sides of the tilapia evenly.
For breaded tilapia, lightly press each fillet into 2–3 tablespoons of panko breadcrumbs or fine cornmeal, coating both sides.
Preheat the air fryer to 400°F (200°C) for about 3 minutes.
Lightly spray the air fryer basket with oil to help prevent sticking.
Place the tilapia fillets in a single layer, leaving space between them for proper air circulation.
Air fry at 400°F (200°C) for 7–9 minutes. No flipping is needed for fresh or thawed fillets.
Check that the fish is opaque and flakes easily with a fork. For the most accurate result, the thickest part should reach 145°F (63°C).
Remove from the air fryer, squeeze fresh lemon juice over the fillets, and garnish with fresh parsley if desired. Serve immediately.
