A comforting and cheesy Crockpot Hamburger Potato Casserole made with layers of seasoned ground beef, tender potatoes, creamy mushroom sauce, and melted cheddar cheese. Perfect for an easy family dinner or potluck.
For extra creaminess, stir 1/2 cup sour cream into the sauce mixture.
Yukon gold potatoes hold their shape better than russets.
Vegetables like corn, peas, or green beans can be added to the layers.
For a crispy topping, transfer to an oven-safe dish and broil for 2–3 minutes before serving.
