If you love a bit of heat, this recipe is for you. Using a food processor, blend together a mixture of Cajun spices, garlic, and olive oil. Coat the chicken legs with the spicy marinade and let them sit for a while to absorb the flavors. Then, place the chicken legs in the air fryer and cook until they are crispy and cooked through. The result is a deliciously spicy and flavorful chicken dish that pairs well with a side of coleslaw or cornbread.
