This brunch potato casserole is the perfect dish to serve for a cozy weekend gathering. It's a comforting blend of shredded potatoes, sour cream, cheddar cheese, and cream of chicken soup, all baked to golden perfection. The chopped onions add a delightful crunch, while the melted butter drizzled on top ensures a rich, savory flavor in every bite.
If you don't usually keep cream of chicken soup in your pantry, you might need to pick up a can at the supermarket. This ingredient is essential for adding a creamy texture and depth of flavor to the casserole. Additionally, make sure you have enough shredded potatoes on hand, as they form the base of this dish.

For freezing, portion the casserole into individual servings or keep it whole. Wrap each portion tightly with plastic wrap, then aluminum foil to prevent freezer burn. Label with the date.
Store the wrapped portions in a freezer-safe bag or container. The casserole can be frozen for up to 2-3 months.
To reheat from frozen, remove the plastic wrap and foil. Place the casserole in an oven-safe dish. Cover with foil and bake at 350°F (175°C) for 45-60 minutes, or until heated through. For a crispy top, uncover for the last 10 minutes of baking.
