Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes. Lightly spray the basket to prevent sticking.
Prep the fish: Pat fillets dry with paper towels.
Dry fish browns better and won’t steam.
Season: In a small bowl, mix salt, pepper, garlic powder, onion powder, paprika, and oregano. Brush fish with olive oil, then coat evenly with the spice blend. Add lemon zest if using.
Optional crunch: Sprinkle panko lightly over the top of each fillet and press gently so it adheres.
Air fry: Place fillets in a single layer, leaving space between pieces.
Cook 8–10 minutes for 1/2-inch fillets, 10–12 minutes for thicker cuts. No flipping needed unless your air fryer runs hot on one side.
Check doneness: The fish should flake easily with a fork and reach 145°F (63°C) in the thickest part. If not, cook 1–2 minutes more.
Finish and serve: Squeeze fresh lemon over the top and shower with chopped herbs.
Serve with a simple salad, roasted veggies, or rice.
