Recipe Information
Ingredients
- 4 pieces chicken breasts
- 1 cup mayonnaise
- 1 cup sour cream
- 1 cup Parmesan cheese, grated
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried Italian seasoning
- 0.5 teaspoon salt
- 0.5 teaspoon black pepper
- 1 cup panko breadcrumbs
- 2 tablespoons unsalted butter, melted
- 2 tablespoons fresh parsley, chopped (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
Place the chicken breasts into the prepared casserole dish in a single layer.
In a mixing bowl, combine the mayonnaise, sour cream, grated Parmesan cheese, garlic powder, onion powder, Italian seasoning, salt, and black pepper. Mix well until creamy and smooth.
Evenly spread the mayonnaise mixture over the chicken breasts, ensuring they are well-coated.
In a small bowl, mix together the panko breadcrumbs and melted butter until the breadcrumbs are moistened.
Sprinkle the breadcrumb mixture evenly over the chicken and mayonnaise mixture.
Place the casserole dish in the preheated oven and bake for 30-35 minutes, or until the chicken is fully cooked (internal temperature of 165°F) and the breadcrumb topping is golden brown.
Remove the casserole from the oven and let it rest for 5 minutes before serving.
Optional: Garnish with freshly chopped parsley for added color and flavor.
