Step 1

In a large bowl, break up the crab meat with a fork. Stir in the almond flour, parsley, green onion, Old Bay, salt, and pepper until well combined.

Step 2

Stir in the egg, mayo, and mustard until the mixture is well moistened. Use your hands to form into 4 patties, each about 3/4 inch to 1 inch thick. Place on a waxed paper lined plate and refrigerate at least 30 minutes.

Step 3

Spray or brush the air fryer rack with oil (I used avocado oil spray). Brush melted butter over both sides of the crab cakes and place on the rack.

Step 4

Air fry at 350F for 10 minutes, carefully flipping halfway through cooking.

Step 5

For the mayo, whisk the ingredients together in a small bowl. Serve the crab cakes with lemon and a dollop of spicy mayo.
