Create the breading. Mix almond flour, paprika, onion powder, dried thyme, dried oregano, garlic powder, salt, and black pepper in a shallow dish or bowl.
Crack the eggs into a separate bowl and whisk them until well beaten.
Preheat your air fryer to 400ºF (204ºC).
Bread the chicken legs. First, dip the chicken legs into the beaten eggs, ensuring they're fully coated. Then, cover the chicken legs with the almond flour mixture, pressing gently to adhere the flour and seasonings to the chicken.
Transfer the chicken to the air fryer basket in a single layer. Spray the breaded chicken legs with avocado oil. There should be no white spots.
Air fry the keto chicken at 400ºF (204ºC) for 16 - 20 minutes. After the first 10 minutes, flip the chicken legs and spray more avocado oil on top if necessary. Continue air frying until the chicken legs reach an internal temperature of 165ºF (74ºC).
Once done, transfer the keto fried chicken to a plate lined with paper towels to remove any excess oil. Let the chicken rest for 5 minutes.
Serve and enjoy with your favorite keto-friendly dipping sauce, a side salad, or some cauliflower rice for a satisfying meal.
