I have found these tips to be helpful. 1. Brush you basket well with oil. 2. Preheat your Air fryer for 4 minutes. 3. Do not move around the fish fillets once placed in the basket for cooking. Midway take out the basket to lightly spray or brush oil on the fillets cooking. Don’t try to flip the fillets. They cook well just like this. 4. Take the fillets out of the Air fryer gently after you finished cooking them. 5. If your fillets are still sticking use a parchment paper cut to the size of your basket.
