Notes

  • Store leftovers. Store leftover hash brown casserole in an airtight container in the fridge for up to 3 days. To warm up the leftover casserole, place it in the oven or air fryer until it is reheated and crispy. 
  • Freeze-baked casserole. Place the baked casserole in a freezer-safe container and store it in the freezer for up to 3 months. Reheat: Warm the casserole in the oven at 350°F for 45 minutes or until warmed through. 
  • Freeze unbaked. Assemble the casserole in a freezer-safe baking dish. Freeze without baking and keep for up to 3 months. Reheat: Add the casserole directly into the oven. Bake at 350°F for 1 hour, covered with aluminum foil, and then 30 minutes uncovered.
  • Make ahead. Assemble the unbaked casserole in the baking dish without the cornflakes. Store in the fridge, tightly wrapped, for up to 2 days. Top with cornflakes and butter and bake as usual.
