For the casserole:

  • 32 oz frozen shredded hash brown potatoes *thawed
  • 2 c shredded cheese (Cheddar or a blend) *try 1 cup Cheddar and 1 cup Colby Jack
  • 1 c finely diced onion (white or yellow)
  • 1 c sour cream
  • 10.5 oz cream of celery soup *sub. cream of mushroom
  • 4 tbsp salted butter, melted
  • 1/4 tsp salt, or to taste

For topping:

  • 2 heaping cups plain corn flakes, gently crushed *NOT frosted
  • 4 tbsp salted butter, melted


  • Thaw potatoes for approximately 10 minutes before assembling. Preheat oven to 350°F. Thoroughly grease a 9in x13in. casserole dish. Set aside.
  • In a large mixing bowl, stir together potatoes, cream soup, sour cream, onion, cheeses, salt and 4 tbsp melted butter. Mix well until all potatoes are covered and all ingredients are evenly distributed.
  • Pour potato mixture into greased casserole dish and fill, leveling the top.
  • In a small bowl, combine the gently crushed corn flakes with the remaining 4 tbsp melted butter. Stir until corn flakes are evenly coated.
  • Pour buttered corn flakes on top of casserole mixture and spread to evenly cover. Press some of the topping down slightly to avoid too many loose flakes.
  • Bake uncovered on 350°F for 55-60 minutes, or until top is lightly browned.
    Let stand for 10 minutes before serving. Refrigerate any leftovers, up to 4 days.


  • You can make this recipe in 2 smaller glass dishes (6 to 8 cups each) and bake for 45-50 minutes, until browned. Enjoy one right away then freeze the other for later.
  • To make ahead: assemble everything but the corn flake topping and cover in the refrigerator for up to 2 nights. Remove from fridge and top with corn flake mixture then bake as instructed.
  • To freeze: bake as directed then cool. Top with foil or parchment and cover with an airtight lid. Freeze for up to 1 month (due to dairy and sour cream). To reheat from frozen: bake on 350 degrees F, covered with foil, until heated through.
