A stress-free, make-ahead breakfast casserole that cooks in the slow cooker overnight, featuring fluffy eggs, savory sausage, and tender hash browns. Perfect for Christmas morning or any lazy weekend.
For best texture, cook on LOW. Thaw hash browns slightly to avoid watery casserole. Do not over-whisk eggs. Let casserole rest 10 minutes before serving. Can be assembled the night before and refrigerated; add 15 minutes to cooking time if starting cold.
