This creamy, savory casserole is a weeknight lifesaver. It combines frozen hash browns, chicken sausage, and sharp cheddar in a slow cooker for a hands-off, comforting meal that feels indulgent but is packed with protein.
Use frozen hash browns to prevent a watery casserole. Avoid opening the lid during cooking. For a gluten free version, use a certified GF cream soup. For extra protein, swap sour cream for plain Greek yogurt.
