Hash Browns or Hashbrowns?

Spell check might disagree, but you can spell it either way! Hashbrowns, hash browns, or hashed browns (whew!) are a staple at our house. But no matter how you spell it, this hashbrown breakfast casserole is a must-bake!

If you happen to have shredded hash browns handy, you can use those in place of the patties. Just distribute evenly in a half-inch layer on the bottom of the dish.

Perfect for Special Occasions or Every Day

We love a good breakfast bake for a holiday breakfast, like Christmas morning. But this casserole is easy enough for every day. I love that you can feed a crowd with the (it serves 12) or save it for the rest of the week.

Spice it Up or Down

I’ve made this hash brown casserole with Pepper Jack cheese before and it’s so good. If you want to kick it up another notch, try adding a dash of hot sauce before eating. And if you have some picky eaters, it’s okay to leave out the red and green pepper. It loses a bit of the flavor for me, but does make it more kid-friendly.
