The best thing about this casserole – besides its delicious flavor – is that you can prepare it ahead of time and let it rest in the refrigerator overnight. Then just pop it into the oven in the morning! That means it’s perfect for Sunday brunch or holiday breakfasts when you want to enjoy a nice breakfast but don’t want to spend a lot of time fussing in the kitchen.

A lot of recipes for breakfast casserole call for cooking the hash browns before adding them in with the rest of the ingredients. I’ve found that step to not only be unnecessary but to actually interfere with the texture of the final dish. Using raw hash browns means the potato will combine with the egg into a creamy casserole with the texture of scrambled eggs.

Just be sure to defrost the hash browns and blot them dry with a kitchen towel – adding them in frozen incorporates too much liquid into the recipe and prevents the casserole from setting properly.
