This hash brown is packed full of cheesy goodness and topped with a crunchy corn flake cereal crust. Don’t plan on having any leftovers of this dish, people always go back for a second helping on this potluck dish.

Credit for this delicious baked hash brown casserole totally goes to my sister-in-law. This is her dish that she brings to Christmas dinner every year. I finally asked for her recipe after my husband wouldn’t stop talking about how good it was. I swear he filled up his plate with the baked hash brown casserole then grabbed a few bites of everything else.

After making this recipe a few times and having TONS of leftovers, I figured out I could divide the recipe up into 2 portions and freeze the second portion for another day. It freezes really well.
