This easy, flavorful, Gluten-Free Breakfast Casserole is the perfect one-pan dish. Packing a punch with buttery hash browns, scrambled eggs, savory sausage, and melty cheese, this dish brings all the best breakfast foods together in a single bite. Every major breakfast we have usually includes this awesome dish!
I love making this easy breakfast for my family anytime. However, we especially enjoy it on Easter and Christmas morning with our BEST gluten-free cinnamon rolls.
One of the best things about it is that it can be made the night before and stored in the refrigerator to bake up first thing in the morning.
You can also make these quick and easy banana egg oat pancakes from our friend Erin at Meaningful Eats for a sweet accompaniment.
Can you use a different breakfast meat in this recipe?
Yes, you can sub in turkey sausage but be sure to flavor it with 1/4 tsp. sage and some salt and pepper. Chorizo (like in this chorizo frittata), Canadian bacon or leftover ham also work great.
You could also sub in crispy chopped bacon. Go extra meaty and use both bacon and sausage to really please your taste buds!
Pro Tip: One of my favorite ways to create more flavor and color is to add fresh vegetables! Red and green bell peppers are great as are canned diced green peppers. I also like adding in chopped green onions, mushrooms or even asparagus.
Are store-bought hash browns gluten free?
While many store bought hash browns are gluten free, be sure to always check. I’ve been surprised how many have wheat flour or other gluten ingredients in them.
Look for a brand that is labeled gluten free and if you have celiac disease, make sure it wasn’t made in a facility where gluten was present.
How to make gluten-free breakfast casserole
How to make gluten-free breakfast casserolePreheat the oven to 350 degrees. In a large bowl whisk eggs, salt and pepper (as shown in photo 1).

Can you make this ahead of time?
I love assembling this delicious breakfast casserole recipe the night before, especially on holidays. I then cover it with tinfoil and bake it the next morning as directed in the recipe.
Can it be frozen?
Yes, if you want to freeze the casserole and reheat it later. Simply prepare as normal and pre-bake the casserole for 30 minutes. Cool to room temperature and then cover tightly with aluminum foil. You can freeze it for 1-2 months.
When you are ready to enjoy, remove it from the freezer and reheat in a 350˚F oven for 1 hour with the foil on.
Uncover and bake for another 30 minutes until completely warmed through and the cheese is browned on top.
Can you make this dairy free?
Absolutely. A couple of my kiddos have dairy allergies so we’ve been exploring how to make many of our recipes without that delicious dairy. This breakfast recipe calls for cheese and butter, but you can substitute your favorite brand of dairy-free cheese and vegan butter.

I have a few questions/comments:
1. Why does the recipe call for frozen hashbrowns? Do they get thawed before assembling? I am going to put it together tonight and bake it in the morning….so do I assemble it with frozen hashbrowns?
2. I am going to use more eggs than called for 2 or 3 more. I am assuming that I would add extra ingredients (peppers,onions,mushrooms) to the eggs and then pour over the frozen potatoes….right?
3. Do the extra ingredients need to be cooked first?
4. Is the foil off for baking?
Chandice says
If you assemble it the night before, just pull it out and let it sit for 10 minutes before baking. Yes we use frozen hash browns and no they don’t get thawed before. It’s fine if they thaw in the fridge for an overnight assembly though. You can add all the extra add ins like veggies you want and it’s up to you if you want them cooked before or not. It isn’t necessary. You can also add more eggs but you may have to cook it longer. You can bake with foil off or on depending on how crispy you want the top cheese. I like to bake with it off.
