How to Make Mashed Potato Casserole

Peel and chop the Yukon Gold potatoes into chunks, ensuring they're evenly sized for consistent cooking. Place them in a large pot filled with cold salted water, bringing it to a gentle boil.
-
Boil the potatoes for 15–20 minutes until they're fork-tender. This step is crucial for achieving that creamy texture; you want them soft enough to mash easily.
-
Drain the potatoes carefully, returning them to the pot after draining. Let them sit for a minute, allowing steam to escape and enhancing their fluffiness.
-
Mash the potatoes using a masher, ricer, or hand mixer until they’re smooth and creamy. Feel free to make them as rustic or as velvety as you prefer!
-
Mix in the unsalted butter, sour cream, milk or heavy cream, and cream cheese, if using. Stir until everything is fully incorporated and the mixture is luxurious and creamy.
-
Season with salt and black pepper to taste. If you opted for garlic, fold it in at this stage; it'll lend a delightful savory note to your casserole.
-
Transfer the mashed potatoes into a buttered 9×13-inch baking dish and smooth out the top with a spatula, ensuring an even layer for beautiful baking.
-
Optional: Dot the top with additional butter or sprinkle cheese for an extra indulgent layer before baking, creating a golden and bubbly crust.
-
Bake at 350°F (175°C) for 25–30 minutes until the casserole is heated through and lightly golden. Keep an eye on it for that perfect crust!
