Convenient frozen hash browns create a crunchy crust for this cheesy egg casserole that’s great for breakfast, lunch, or dinner. A little bit of cheese combines with the potatoes to help the crust hold together and brown more deeply. Not counting salt, pepper, and nonstick spray (which we consider freebies), this recipe only requires five ingredients, most of which many people keep on hand as fridge and freezer staples. Be sure to let the casserole stand for a few minutes before cutting into it so everything has a chance to settle.

Frozen shredded hash brown potatoes
