Preheat your air fryer to 375ºF for at least 3 minutes, according to the manufacturer’s instructions for your particular model.
Cut your chicken breasts in half widthwise to create two thinner pieces from each single chicken breast.
Add 1 tablespoon of avocado oil to a large bowl, then add in all of the seasonings. Whisk the seasonings and oil together until completely combined.
Add the halved chicken breasts to the bowl of oil and seasonings, tossing to coat each of the pieces in the seasoned oil.
Once the chicken pieces are well coated, add them in a single layer to the basket of the preheated air fryer. Leave plenty of room between each piece of chicken, working in batches as needed.
Cook the chicken in the air fryer for 6-10 minutes, or for 3-5 minutes per side. Make sure to flip the chicken halfway through the cooking time for even browning.
Once the chicken reaches a minimum internal temperature of 165ºF at the thickest part, it’s cooked through. Remove from the air fryer to a plate.
Repeat with any remaining chicken.
Serve and enjoy with your choice of dipping sauce, or how you prefer to serve blackened chicken.
