Preheat your air fryer to 375°F for 5 minutes.
Pat the chicken sausages dry with a paper towel and insert a sturdy wooden skewer into the end of each link.
In a small bowl, whisk the egg until completely smooth and slightly frothy.
Stir in the almond flour, cornmeal, baking powder, sea salt, and garlic powder until a thick, uniform batter forms.
Pour the batter into a tall, narrow glass and dip each sausage until it is fully submerged and coated.
Lightly coat the air fryer basket with avocado oil spray to prevent sticking.
Place the coated sausages in the basket and spray the tops lightly with avocado oil.
Air fry for 10-12 minutes, flipping halfway through, until the exterior is beautifully browned and crisp.
