Preheat your oven: Start by preheating your oven to 400°F (200°C). Prepare a baking dish by greasing it lightly to prevent sticking.
Prepare the breadcrumb mixture: In a medium bowl, combine 1/2 cup of grated Parmesan cheese, 1/2 cup of Panko breadcrumbs, 2 tsp of garlic powder, 1 tsp of Italian seasoning, salt, and pepper to taste. Mix well to ensure that all dry ingredients are evenly distributed.
Brush the chicken: Take your four boneless, skinless chicken breasts and brush them with 2 tbsp of olive oil. This will help the breadcrumb mixture stick and create a beautifully golden crust.
Coat the chicken: Once the chicken breasts are evenly brushed with olive oil, generously coat each piece with the breadcrumb mixture, pressing down slightly to ensure the coating adheres well.
Arrange in the baking dish: Place the coated chicken breasts in the greased baking dish. Drizzle 1/4 cup of melted butter evenly over the top of the coated chicken to enhance flavor and crispiness.
Bake to perfection: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the chicken is golden brown and registers 165°F (74°C) in the thickest part when tested with a meat thermometer.
Garnish and serve: Once the chicken is cooked through, remove it from the oven, garnish with freshly chopped parsley, and serve immediately.
