Our creamy chicken and rice casserole seems old-school, but comes together fast, so you can enjoy it for a weeknight dinner. This comforting, nostalgic dish uses rotisserie chicken and precooked or leftover rice to streamline prep. Quick-cooking mushrooms and frozen peas round out the dish, which is bathed in a flour-thickened brothy sauce enriched with sour cream for an irresistibly creamy texture. Once assembled, the casserole only needs 15 minutes in the oven—just enough time to make a salad to round out the meal.
