Spicy Baked Picnic Chicken

cooking spray

1 cup buttermilk

1 (1.25 ounce) package taco seasoning mix, divided

⅛ teaspoon cayenne pepper

1 cup bread crumbs

1 cup grated Parmesan cheese

¼ cup all-purpose flour

½ teaspoon onion powder

½ teaspoon salt

¼ teaspoon ground black pepper

4 skinless, boneless chicken breast halves

Preheat the oven to 375 degrees F (190 degrees C). Spray a broiler pan with cooking spray.

Whisk buttermilk, 1 teaspoon taco seasoning, and cayenne pepper together in a bowl.

Mix remaining taco seasoning, bread crumbs, Parmesan cheese, flour, onion powder, salt, and black pepper together in a separate bowl.

Dip chicken in buttermilk mixture; coat with bread crumbs mixture. Place coated chicken in broiler pan.

Bake in the preheated oven until chicken is longer pink in the center and coating is crispy, 30 to 35 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
