• Thickness: The cooking time can vary depending on the thickness of your cod fillets. Thicker pieces may need a minute or two longer to cook thoroughly.
• Don’t Overcrowd: Make sure the cod fillets don’t overlap in the air fryer. Overcrowding can lead to uneven cooking and less crispiness.
• Check for Doneness: Use a fork to check if the cod flakes easily. This is a good indication that your fish is perfectly cooked. You can also use a meat thermometer to check the internal temperature which should read 145 °F (63 °C).
• Season to Taste: Feel free to experiment with different herbs and spices. Adding a bit of garlic powder, smoked paprika, or chili powder can introduce a new flavor profile to your dish.
• Pat Dry: Always pat the cod dry before seasoning to remove excess moisture. This helps the seasoning stick better and promotes a crispier finish.
• Use Fresh Lemon: If possible, use fresh lemon juice rather than bottled for a brighter, more vibrant flavor. Add some lemon zest or an extra squeeze after cooking to amp up the flavor.
• Frozen Cod: You can use frozen cod. Just make sure to thaw it completely and pat it dry before seasoning and cooking.
• Other Fish: This recipe works well with other white fish like tilapia, haddock, or halibut. Adjust cooking times based on the thickness of the fillets.

Storage and Reheating Instructions

• Cool and Airtight: Allow the cod to cool completely before storing it, and then transfer it into an airtight container. 
• Refrigerate: Place the container in the refrigerator as soon as possible. Cooked cod should be eaten within two days for the best quality.
• Reheating: When ready to eat, reheat the cod in the air fryer at 350°F for a few minutes until it's warmed through. You can also microwave it for a minute or until it’s heated through.
