Take the cod out of the package and pat it dry with paper towels. Cut it into pieces that fit in the air fryer basket.
Mince the garlic and juice the lemon if using a fresh lemon.
Using parchment paper in the air fryer will make cleanup easier. Put a piece in the bottom and put the piece of cod on top, with the skin side down.
Drizzle the fresh lemon juice and olive oil on top of the filets. Sprinkle on the paprika, salt, black pepper, and minced garlic.
Air fry the fish at 370 degrees F for 8-10 minutes, cooking until the fish is just done. Check that the internal temperature has reached 145 degrees F or that the cod flakes easily with a fork.
Serve with lemon slices and sprinkled with fresh herbs.
