How to Make Twice Baked Potato Casserole
-
Preheat Oven: Start by preheating your oven to 375°F (190°C). This step is crucial as it ensures the casserole cooks evenly throughout, resulting in a creamy and comforting dish.
-
Prepare Potatoes: Wash and prick the potatoes with a fork. Bake them in the oven for 45-60 minutes until they’re fork-tender. The skins should be slightly crispy while the insides remain soft.
-
Cool and Cube: Once baked, plunge the potatoes into ice water for easy peeling. After a few minutes, remove them, peel the skins, and cut the potatoes into cubes—this helps in mixing them nicely!
-
Mix Ingredients: In a large bowl, combine the potato cubes, unsalted butter, sour cream, milk, onion powder, garlic powder, salt, pepper, half of both the cheddar and Monterey Jack cheese, half the bacon, and half of the green onions. Mash everything together until well-mixed and creamy.
-
Assemble Casserole: Spoon the potato mixture into a greased casserole dish and top it with the remaining cheese, bacon, and green onions. The golden cheese on top will make it extra inviting!
-
Bake: Cover the dish with foil and bake for 30 minutes. Then, uncover and bake for an additional 10 minutes, or until heated through and the cheese has melted into a bubbly goodness.
Optional: Garnish with extra green onions for a fresh pop of color and flavor.
