Remove the package of Gardein Golden Fishless Filets from the freezer while you prepare the coating.
Mix the pecans, cornmeal, flaxseed, water, and Cajun seasoning blend in a small bowl that will fit a whole fillet. Once mixed together it will be a very thick batter.
Using your hands, press the coating on the top and bottom of a filet, then as you flatten it with your palms cover the edges as well. Get small bit of the batter as you need to cover the whole filet.
Once coated, place on a piece of parchment paper cut for your air fryer that leaves 1 inch around the inside of the basket for the air to flow through. (alternatively, you can use round dumpling parchment paper with holes.
Repeat until the basket is full but not crowded. Cook at 390 degrees (or 400 degrees depending on how high your air fryer goes), for 10 minutes. Flip and cook for 3 to 5 minutes more, or until the center is piping hot. (Check this by putting a fork in the center and carefully touching it.)
Note: If you have a small air fryer you may need to make this in 2 batches.
I recommend serving with rice and hot sauce. I used my Instant Pot dirty rice recipe and you can find it here.
One serving is 2 filets, but with the pecan coating you may find that light eaters only need one. This recipe makes a total of 6 filets.
