Prep the jalapeño peppers by slicing them open, removing the seeds and endocarp (the whitish membrane that seeds are attached to.) to remove the heat from the jalapeños. Leave intact if you want the heat.
Dice the jalapeños in small pieces.
Add cream cheese, shredded cheese, half of the spices, diced jalapeño peppers, and chopped bacon to a mixing bowl and fully incorporate. Set aside.
Cut along the side of the breast to form a pocket in the middle. Don’t cut from end to end and don’t cut through as to butterfly the breast. Fill the pocket of chicken with the cream cheese filling, evenly distributed between the four breasts.
Season the breasts with the remaining spices and set them aside.
Add the bread crumbs to a shallow dish and pace each breast on top of the crumbs to fully coat the breast.
Place the breast in an oil-sprayed air fryer basket. Then spray the top of the breast with oil. Filling pocket facing up. Press down slightly to form a flat bottom.
Cook at 350° for 18 minutes or until fully cooked.
