Preheat your oven to 375°F (190°C).
Prepare a baking dish by greasing it lightly.
In a bowl, mix the crushed Ritz crackers, Parmesan cheese, garlic powder, onion powder, salt, and pepper.
Dip each chicken breast into the melted butter, ensuring it's fully coated.
Roll the buttered chicken in the cracker mixture, pressing gently to adhere.
Place the coated chicken breasts in the prepared baking dish.
Drizzle any remaining butter over the top of the chicken.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through.
Check the internal temperature; it should reach 165°F (75°C).
Let it rest for a few minutes before serving.
