Hashbrown Casserole Breakfast Substitutions
Olive Oil: You can substitute olive oil with avocado oil or melted butter.
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.

Made this for my family on Christmas morning and it was a huge hit. Great recipe with ingredients I had on hand and super easy to put together.
The Clean Eating Couple says
So glad you all enjoyed it!
Berni says
This probably tastes AMAZING right out of the oven, but I used this for my breakfast meal prep so I had a warm breakfast for the whole week. My husband took my 6th piece when this came out out of the oven and he really enjoyed it….maybe when I make it again this weekend, I won’t share 🙂
Berni says
I posted too soon – sorry.!! This was really really good warmed up still and lasted beyond the 3 days called out in the recipe – but I’m a risk taker . Sometimes eggs don’t do well but this worked and I’ll be making again
The Clean Eating Couple says
So glad you liked it!
Cheryl says
This was such a fantastic recipe! Doing the January whole 30 and will be traveling this week so this is the most perfect meal prep breakfast! Are used grated potatoes instead of frozen hashbrowns since I cannot find any that were whole 30 compliant. Also I did onion and garlic powder instead of basil and parsley simply because I did not have it. Turned out flavorful and robust!
Next time I will do with cheese when I’m not on w30 because I am sure that is the icing on the cake!!!
The Clean Eating Couple says
So glad you liked it, Cheryl! Thank you!!
Danielle K. says
We just made this for an easy dinner tonight and it was great! I only had 12oz sausage, but that was still enough. Other than that followed the recipe as written. My husband loved it so I’ll be putting it in a regular make ahead breakfast rotation for him to grab on his way to work.
Priscilla says
I made this for a few friends we had over this weekend & it was a hit! Everyone had seconds, and a couple— even thirds. I did half cup of red and green bell pepper each and also added spinach. Sooo tasty and filling. I had the last bit of leftovers this morning for breakfast and it was still JUST as good after reheating in the microwave. I am adding this to my recipe cards and it is going to be my “go to” when we have company over for brunch. Oh! I also added the green pepper Cholula sauce on top of my slice for an extra kick and it pairs deliciously. Thank you for this recipe!
The Clean Eating Couple says
So happy you all enjoyed it!
Wendy says
Is there a reason you don’t use salt?
The Clean Eating Couple says
Yes, because cheese and breakfast meats like breakfast sausage and bacon are high in sodium. frozen Hashbrowns also often have added salt. feel free to add it if you want but it doesn’t really need it
Leanna says

Liz kane says
Made this morning for breakfast. I am not an egg person but this was super easy and tasty! I like a bit more well done so I cooked 35min. I also like more spice so next time I’ll use a seasoned breakfast sausage or add more seasoning like red pepper flakes.
ElizabethTaylor says
This was such an easy and delicious breakfast for a crowd! It was so easy to make the night before and then just heat up the next morning.
Maggie says
I made this using my own chicken breakfast sausage made in the food processor with Penzey’s breakfast sausage seasoning for a super low point breakfast. Thanks for sharing this!!!
Sandy says
Best recipe for this dish I have ever made. Made it for some dear freinds of ours and they loved it. So easy and tasted so good! Thank you
Jen says
Have you ever made this in a muffin tin?
The Clean Eating Couple says
No I havent, sorry! It’s very easy to make in a big dish and just slice into individual portions.
Melissa says
I made this for a brunch today and everyone loved it!! I can’t have cheese so I left it out, and I used a combination of red and orange bell peppers. I also didn’t have frozen hashbrowns so I shredded some yukon gold potatoes in my food professor and partially fried them before mixing in. Absolutely delicious!
Crystal Burns says
Love this breakfast casserole. Makes good leftovers as well.
Missy Bailey says
If I cut this in half, will it be just as good?
The Clean Eating Couple says
I don’t see why not! It might need a little less time to cook!
Jerry Bouyear says
Well there is a first and last time for everything. Verry watery after baking I managed to eat it but it was like soup with a crust.
The Clean Eating Couple says
Something clearly went wrong. Did you thaw the hashbrowns? If not, that’s probably what went wrong here.
Lisa Emfinger says
I made this last week for the first time & it was fantastic! I divided the portions, refrigerated it & ate it all week after heating in the microwave 👍
