FAQ
Can I cook frozen salmon in the air fryer?
Thaw salmon completely first for even cooking. Frozen salmon will cook unevenly and may be soggy inside while overcooked outside.
What if my salmon filets are thicker than 6 ounces?
Add 2-3 minutes cooking time for thicker filets. Check doneness with fork - fish should flake easily when ready.
How long will leftover salmon keep?
Cooked salmon stays fresh in refrigerator 3 days. Reheat gently in air fryer for 2-3 minutes to maintain texture.
