Ingredients
  • 1 (30 ounce) package frozen shredded hash brown potatoes, thawed
  • 2 cups (8 ounces) shredded cheddar cheese
  • 1/2 cup plus 2 Tablespoons melted butter, divided
  • 16 ounces sour cream
  • 1/2 teaspoon pepper
  • 1 can (10.5 ounces) condensed cream of chicken soup, NOT diluted
  • 2 cups coarsely crushed Corn Flakes cereal (I used about 3 1/2 cups of whole Corn Flakes to equal 2 cups crushed)
Instructions
  1. Preheat oven to 350 degrees F. Spray a 9 x 13-inch baking dish with cooking spray and set aside.

  2. In a large bowl, whisk or stir together shredded cheese, 1/2 cup of the melted butter, sour cream, pepper and condensed soup.

  3. Fold in the thawed shredded potatoes. Transfer potato mixture to the prepared baking dish.

  4. Next, prepare the topping for the casserole by combining the crushed Corn Flakes with the remaining 2 tablespoons of melted butter in a small bowl until the cereal is coated. Sprinkle on top of the potato mixture in the baking dish.

  5. Bake, uncovered, for 40-45 minutes (or until heated through and topping is browned).

Can Hash Brown Casserole be Made the Night Before?

Can Hash Brown Casserole be frozen?

Yes! You can safely freeze this hash brown breakfast casserole before baking. Thaw in the refrigerator overnight before baking.

Alternatively, you can freeze the casserole after baking as well! Allow a baked casserole to come to room temperature before wrapping tightly and freezing for up to 3 months.

How to Reheat Hash Brown Casserole:

To reheat leftovers or to reheat a previously baked (and then frozen) hash brown casserole, bake in oven at 350 degrees for approximately 30 minutes, or until heated through. If you would like to prevent further browning on top, simply place a loose cover of foil over top of the casserole while it's reheating in the oven.
