For a comforting Southern-style chicken rice casserole, start by preheating your oven to 350°F (175°C). In a large mixing bowl, combine cooked, shredded chicken with a can of cream of chicken soup and a cup of cooked rice. Add in a cup of milk, a handful of frozen mixed vegetables, and season with salt, pepper, and a sprinkle of garlic powder for extra flavor. Stir everything together until well combined, then pour the mixture into a greased baking dish. Top with shredded cheddar cheese for a gooey finish. Bake for about 30-35 minutes, or until bubbly and golden on top. This hearty casserole is not only easy to make but also a perfect dish to gather the family around the table. Enjoy!
