Loaded Mashed Potato Casserole

Step 4: Assemble the Casserole

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish. Spread the mashed potato mixture evenly into the dish, smoothing the surface with a spatula.

Sprinkle the remaining cheddar cheese over the top. Add the reserved bacon and green onions for a beautiful finish.

Brush the surface lightly with melted butter to encourage a golden top during baking.

Step 5: Bake Until Golden

Cover the casserole loosely with aluminum foil and bake for 20 minutes.

Remove the foil and continue baking for another 10 to 15 minutes, or until the cheese is fully melted and bubbly around the edges.

For an extra golden top, broil for 2 to 3 minutes at the end of the baking time. Watch carefully to prevent burning.

Step 6: Rest and Serve

Remove the casserole from the oven and allow it to rest for about 5 minutes before serving. This helps the casserole set and makes it easier to scoop.

Garnish with additional green onions if desired.
