This 4-Ingredient Slow Cooker Mother’s Day Scalloped Potato Casserole is creamy, cheesy, and effortlessly comforting. Frozen hash browns, condensed soup, cream, and cheddar layer together in the slow cooker for an easy holiday breakfast or side dish.
Do not leave the finished casserole on WARM for more than 2 hours before refrigerating leftovers. Store leftovers in shallow containers in the refrigerator for 2 to 3 days. Reheat portions until steaming hot, adding a small splash of cream or milk if needed. The casserole can also be reheated in a covered baking dish in the oven.
