- Bake to perfection: Place the casserole in the preheated oven and bake uncovered for 40–45 minutes, or until the cheese on top is melted and lightly browned and the casserole is bubbling around the edges. If you prefer a slightly crispier topping, you can broil for 1–2 minutes at the end, watching carefully to prevent burning.
- Cool slightly before serving: Remove the casserole from the oven and let it rest for about 5 minutes before serving. This short resting time allows the creamy filling to thicken slightly and makes portioning easier. Garnish with chopped parsley or green onions if desired for a touch of color and freshness.
- Serving suggestions: Serve warm as a complete meal or alongside a simple green salad or steamed vegetables for balance. The creamy potatoes and savory beef pair beautifully with crisp or tangy sides.
Storage and Reheating Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 325°F (165°C) until warmed through, or microwave individual portions for convenience. To keep the top cheese layer from drying out, cover loosely with foil during reheating. This casserole can also be assembled ahead and refrigerated overnight before baking — just add an extra 10 minutes to the bake time.
