Rinse and dry the cauliflower head well with paper towels.
Place the head of cauliflower in a large bowl and spray the bottom with avocado oil.
Flip the cauliflower over and spray with oil and then pour the Buffalo sauce over the top and brush to cover the whole head.
Move to the air fryer basket and cook at 400˚ for 20 minutes. Depending on the size of your cauliflower it may take a few minutes more or less to cook.
Spray with oil again and cook another 5 minutes. This helps the sauce get crispy.
Squeeze the lime juice over the entire head prior to serving.
Enjoy!
