Start by patting the chicken breasts dry with a paper towel. This helps them brown nicely and makes that seasoning stick better. You will feel the surface getting a little tacky, so do not skip this step. Remember, wet chicken does not crisp!
In a bowl, mix the grated parmesan, ranch seasoning, garlic powder, smoked paprika, salt, and cayenne. The aroma of the spices will start to mix, creating a savory scent. Just be cautious not to put in too much cayenne unless you like it spicy!
Spread the mayonnaise over each chicken breast evenly. This adds moisture and helps everything stick. The silky texture feels great and will give a nice crust later. Just ensure the chicken is fully coated for the best result.
Sprinkle the parmesan mixture over the mayo-coated chicken, pressing it in slightly to adhere. You will see the chicken becoming beautifully coated. Make sure it is evenly covered, or some bits will not cook as well.
Before you place the chicken in, preheat the air fryer so it is hot when you add your chicken. You want it to be nice and warm, which gives the chicken that perfect golden finish. Skipping this step can lead to uneven cooking.
Gently place the chicken breasts in the air fryer basket in a single layer. You will hear a satisfying sizzle as they cook. Avoid crowding the basket since that can result in soft spots instead of crispy ones.
Toward the end, be sure to check the internal temperature. You want it cooked through, but not overdone, or the chicken will dry out. Relying solely on time is not foolproof; each air fryer can vary a bit.
Once done, let the chicken rest for a few minutes before cutting into it. You will be greeted with juicy, flavor-packed bites. Skipping the resting period can make it tougher, so take that moment! Enjoy your meal!
