A comforting and hearty casserole featuring tender potato slices layered with a rich, savory ground beef and cheese sauce. This easy, family-friendly meal is perfect for a cozy weeknight dinner, delivering maximum flavor with minimal fuss.
For best results, ensure potato slices are patted dry to prevent a watery sauce. Letting the casserole rest before serving allows the layers to set for neat slices. This dish can be assembled a day ahead and refrigerated before baking, or frozen for up to 3 months (thaw in fridge before baking).
