Recipe Notes and Expert Tips

  • Quality Potatoes: Start with high-starch potatoes like Russets for a firmer, crispier texture that holds up well in the casserole.
  • Properly Precook: If you’re using fresh potatoes, make sure to parboil them first. This cuts down on the baking time and helps with texture.
  • Season Well: Don’t underestimate the power of salt, pepper, and your chosen spices. Season the hash browns before mixing them with other ingredients.
  • Mix-in Magic: Add-ins like diced onions, bell peppers, or cooked veggie bacon can elevate your hashbrown casserole to the next level.
  • Use the Right Dish: Opt for a baking dish that allows the casserole to spread evenly, ensuring consistent cooking.
  • Let It Rest: After you pull it out of the oven, give your casserole a few minutes to settle. This makes it easier to cut and allows the flavors to meld.

How To Store Leftover Hashbrown Casserole

Store your cheesy casserole in the fridge covered with aluminum foil for up to three days and freeze for up to three months.
