Preheat the Oven: Start by preheating your oven to 400°F (200°C). This will give you the ideal temperature to achieve that crispy finish.
Marinate the Chicken: Take the 4 boneless, skinless chicken breasts and immerse them in 1 cup buttermilk. Let them marinate for at least 30 minutes. This step is vital as it enhances flavor and keeps the chicken moist.
Prepare the Coating: In a large mixing bowl, combine 1 cup all-purpose flour, 1 tsp paprika, 1 tsp garlic powder, 1/2 tsp salt, 1/2 tsp black pepper, 1/4 cup grated Parmesan cheese, and 1/4 cup breadcrumbs. Mix these ingredients thoroughly until well combined.
Coat the Chicken: Remove the marinated chicken from the buttermilk and allow any excess to drip off. Roll each chicken breast in the flour mixture, ensuring an even coating. This will create that irresistible crunch.
Place on Baking Sheet: Once coated, place the chicken breasts on a baking sheet lined with parchment paper. Drizzle 2 tbsp melted butter over the chicken for an extra crispy finish.
Bake: Insert the baking sheet into the preheated oven. Bake for 25-30 minutes or until the chicken is golden brown and cooked through. Flip the chicken halfway through cooking to ensure even browning.
