Lightly brush or spray both sides of the frozen fillets with oil. Sprinkle generously with your preferred seasoning blend.

Step 3: Air Fry to Perfection

• Cook at 390°F for 11–14 minutes, depending on thickness

Pro Tips for the Best Results

Don’t Overcook

Halibut dries out quickly—check for flaking or test with a thermometer at the 11-minute mark.

Use Parchment or a Liner (Optional)

Helps keep delicate fillets from sticking and makes cleanup easier.

Brush with Butter or Add Sauce After Cooking

Garlic herb butter, lemon caper sauce, or a simple drizzle of olive oil takes it to the next level.

Let the Fillets Rest Before Cutting

This allows juices to redistribute for better texture and moisture.
