Hashbrown Casserole Breakfast Substitutions
Breakfast Sausage: Breakfast sausage can be replaced with crumbled bacon or even cooked ham. Most breakfast sausages are high calorie/fat/salt so be aware. You can also use cooked breakfast sausage. Simply crumble it/chop it instead of browning it. If you are wanting to use bacon, try our Bacon Breakfast Casserole.
Veggies: Feel free to add more veggies. Spinach or other greens would be great in this casserole. You could also try our Veggie Egg Casserole!
Eggs: You can add in egg whites if you’d like a higher protein/lower fat option.
Spices: You can add more spices if you’d like or substitute in fresh herbs. For fresh herbs use double the amount compared to dried herbs.
Can I use fresh potatoes instead of frozen hash browns? Yes, you can use fresh potatoes instead of hash browns. Make sure to squeeze out all of the liquid from them. If you don’t prefer hashbrowns, try our Sausage Egg Casserole.
Cheddar Cheese: Feel free to omit cheese from this recipe to make it dairy free. You can also substitute other cheese. We think pepper jack, monterey jack, and shredded mozzarella would all work well.
Hashbrown Breakfast Casserole FAQ
Egg Hashbrown Casserole is supposed to fall and deflate some after coming out of the oven. It’s loaded with dense items like cooked sausage, veggies, and hashbrowns. All of these items are heavy so the casserole should fall a bit after it has cooked.
Yes! You can make Egg Hash Brown Breakfast Casserole ahead of time. It’s best when eaten hot out of the oven, but it can be baked and then cooled/reheated. We don’t recommend mixing this together and leaving it in the refrigerator raw. The potatoes will soak up the eggs.
You can’t leave an egg bake out overnight. Egg bakes must be refrigerated overnight or they can easily go bad and become a food safety issue.
Your hashbrown casserole could be soggy if you’re using too much liquid or you didn’t thaw your hashbrowns. The hashbrowns should be completely thawed and not frozen when added to the casserole.
Yes, you need to cook hashbrown casserole before freezing.
No, you don’t need to cover an egg bake when baking. Unless a recipe states to cover it, most egg bakes can be baked uncovered.
To thaw frozen hashbrowns for casserole simply microwave until they’re no longer cold.
How to store Breakfast Casserole with Hash Browns
How long can you keep a breakfast casserole in the refrigerator? This breakfast casserole will keep in the fridge for up to 3 days. Anything after that is questionable and a potential food safety issue.
Can you freeze Shredded Hashbrown and Egg Casserole? Yes, you can freeze Shredded Hashbrown & Egg Casserole, but we don’t recommend it. We find that frozen/reheated eggs can be a bit soggy but it will work!
Do you freeze an Egg Hashbrown Breakfast Casserole before or after baking? If you are going to freeze this breakfast casserole, cook it completely, allow it to cool, and then freeze it wrapped in freezer paper in a freezer safe Ziploc bag.
