In a large storage bag, combine 3 cups unseasoned breadcrumbs, 2 teaspoons seasoned salt, 2 teaspoons paprika, 1 teaspoon celery salt, 1 teaspoon garlic powder, 1 teaspoon onion powder, and ½ teaspoon black pepper. Close the bag and shake until everything is well combined.
Pat the chicken dry with a paper towel, then coat each piece of chicken with a thin layer of mayonnaise or olive oil using a pastry brush.
Working one at a time, place a piece of chicken into the bag with the seasoning. Close the bag and then shake gently until the chicken is fully covered with the mixture. Remove the chicken from the bag, shaking off excess seasoning and then place the chicken onto a greased baking sheet or greased basket/tray of an air fryer. Repeat with each piece of chicken.
