Step 1: Pre-heat the oven to 350, and grease a baking pan (big enough to fit your chicken breasts).
Step 2: In a bowl combine 1/3 cup melted butter, 2 tablespoons minced garlic, 1 teaspoon garlic powder, and ½ teaspoon seasoning salt.
Step 3: In a separate bowl combine ¾ cup breadcrumbs, ¾ cup grated cheddar cheese, ½ cup parmesan cheese, and ½ teaspoon black pepper. Dip the chicken in the garlic/butter mixture and then roll in the breadcrumb mixture until fully coated.
Step 4: Bake in the oven for 30-35 minutes (If they are really thick, they might take a few extra minutes). Within the last 5 minutes of cooking top chicken breasts with shredded cheddar cheese.
