Place chicken breasts in a bowl or shallow baking dish and cover with buttermilk.
Cover the dish with plastic wrap and refrigerate for a minimum of 3 hours.
Pounding Chicken
Remove chicken from the buttermilk and place either in a small plastic bag or between two pieces of plastic wrap.
Flatten the chicken breasts to approximately ½ inch to ¾ inch thick using a meat pounder. Your goal is a relatively uniform thickness.
Breading Mixture
Combine the flour, baking powder, and spices in a shallow baking pan.
Use a fork to combine the mixture thoroughly.
Breading the Chicken
Dredge each piece of chicken in the flour and spice mixture. Be sure to coat the entire surface thoroughly.
Cooking Option #1 - Deep Frying
Using a deep-fryer or large skillet, heat oil to 130℃/265℉.
If the oil is too hot, you will burn the breading before reaching the required internal temperature of 75℃/165℉.
Working with one piece of chicken at a time, submerge the chicken into the hot oil.
Cook chicken on each side for 5-8 minutes or until the breading is golden and crunch. The internal temperature of the chicken needs to reach 75℃/165℉.
It is important to note that the temperature of the cooking oil will drop during the cooking process. Therefore, allow the oil to reheat before frying your next piece.
Once the chicken reaches the correct temperature and desired golden brown, crunchy texture, remove it from the hot oil and place it on a wire rack over paper towels to allow it to drain.
Cooking Option #2 - Air Frying
Preheat the air-fryer to 204℃/400℉.
Add chicken to the air-fryer basket.
Spritz the surface of the chicken with cooking spray.
Cook for 10-15 minutes. Then pause the air-fryer and flip the chicken.
Cook for 10-15 more minutes or until the chicken reaches the desired level of crispiness.
The internal temperature of the chicken needs to reach 75℃/165℉.
Assembling the Sandwiches
Place a finished chicken breast on a brioche bun. Add any condiments and garden vegetables you desire.
Enjoy!!
