This set-and-forget casserole is the ultimate weeknight comfort food. Savory sausage, tender hash browns, and a rich, cheesy sauce come together effortlessly in your slow cooker. It's a hearty, satisfying meal that simmers all day, filling your home with a welcoming aroma.
Use frozen hash browns directly from the freezer; thawing will make the casserole soggy. For a lighter version, use turkey sausage and low-fat dairy. This casserole can be assembled the night before and refrigerated, then cooked the next day.
