1 cup sour cream
2 teaspoons garlic powder
1 teaspoon seasoned salt
1/2 teaspoon fresh ground black pepper
1 1/2 cups freshly grated Parmesan cheese, divided
3 pounds boneless chicken breasts, trimmed of excess fat
Preheat oven to 375°F. Lightly coat a 9×13 baking dish with nonstick spray and set aside.
In a medium bowl, mix together the sour cream, garlic powder, seasoned salt, pepper, and 1 cup of Parmesan cheese.
Place the chicken breasts evenly into the pan. Spread the sour cream mixture on top of the chicken. Sprinkle with the remaining Parmesan cheese.
Bake for 25-30 minutes, or until the chicken is cooked through.
Turn the oven to broil and place the pan under the broiler for 2-3 minutes until lightly browned on top.
Store airtight in the refrigerator for up to 3 days.
Reheat on microwave or in oven at 350°F for 10 minutes.
