Gluten-Free Breakfast Casserole is a hearty and crowd-pleasing breakfast recipe. Prepped in minutes then baked until golden brown and bubbly!
“This is my absolute favorite breakfast casserole. Even if I didn’t have to eat GF, I would still make this for my family and holiday events. So perfect and delicious!”
I don’t know if this is a Midwestern thing, but I can’t tell you how many breakfast casseroles I’ve eaten in my lifetime. Thousands, probably. Around here we make it for every occasion – holidays, baby and bridal showers, sports team breakfasts, potlucks, birthdays – I mean the list goes on and on.
Breakfast casseroles are not only great for feeding a crowd, but they’re incredibly crowd-pleasing. Hearty, cheesy, and totally delicious.
My Gluten Free Breakfast Casserole is one for the books not only because it’s so flavorful and easy, but because both gluten-free AND non-gluten-free folks absolutely love it. This easy breakfast casserole gets rave reviews anytime I serve it.
Watch How to Make It
Main Ingredients Needed
Snag the everyday items needed to whip up a hot and hearty breakfast casserole at home. Here are the main ingredients you’ll need:
- Shredded frozen hash browns: I use Ore-Ida brand, which is gluten free and has a great consistency. Unlike with my Crock Pot Breakfast Casserole, the hash browns in this casserole DO need to be thawed first, so plan ahead for that.
- Ground pork breakfast sausage: I like Jimmy Dean brand, which is gluten free, and typically stick with the “original” flavor. You could use the spicy flavor for a kick.
- Eggs
- Sour cream: adds to the overall texture and flavor of the breakfast casserole.
- Milk: whatever you’ve got in the fridge will work.
- Shredded cheese: sharp cheddar cheese lends flavor and a golden brown topping to the baked gluten free breakfast casserole.
Can I Make this Ahead of Time?
If you want to make the casserole ahead of time – at night for example, so it’s ready to bake in the morning – I recommend keeping the egg + sausage mixture separate from the hash brown mixture then combining just before baking.
We like to serve breakfast casserole with fresh salsa, guacamole, and a fresh fruit salad. Now let’s dig in!
How to Make Gluten Free Breakfast Casserole
Step 1: Brown the breakfast sausage.
Start by browning ground pork breakfast sausage and chopped shallot or onion in a large skillet over medium-high heat. Drain the sausage if necessary then set it aside to cool slightly.
Step 2: Whisk the egg mixture.
To a large mixing bowl add eggs, salt, and pepper then whisk until smooth. Next add sour cream and milk (any kind) then whisk again until smooth.
Step 3: Combine the remaining ingredients.
Finally, add the browned sausage, shredded sharp cheddar cheese, and thawed frozen shredded hash browns then give everything a good stir to thoroughly combine.
If the mixture seems a little dry, whisk another one or two eggs with a splash of milk then add that in too.
Step 4: Bake the casserole.
Pour the mixture into a nonstick sprayed 9×13″ baking dish then sprinkle with additional cheddar cheese.
Cover the dish with nonstick-sprayed foil then bake for 60-75 minutes at 350 degrees or until the center is set and cooked through. Remove the foil then bake for another 5 minutes or until the cheese is golden brown and bubbly.
Step 5: Rest then serve.
Let the gluten-free breakfast casserole sit for 15-20 minutes before slicing into squares and serving. If you’re lucky enough to have leftovers, they are just as delicious once reheated in the microwave for a minute or two.
However and whenever you make it, I know you’ll love every last drop of my Gluten Free Breakfast Casserole — enjoy!

- 1 large shallot or 1 small onion, chopped
- 6 large eggs
- 1 teaspoon salt
- 1/2 teaspoon pepper
- 8 oz sour cream
- 3/4 cup milk, any kind

Directions
- Preheat the oven to 350 degrees then spray a 9×13" baking dish with nonstick spray and set it aside.

- To a very large mixing bowl, add the eggs, salt, and pepper then whisk to combine. Add the sour cream and milk then whisk to combine. Add 3/4 of the shredded cheese, the cooked and slightly cooled breakfast sausage, and thawed hash browns then stir to combine.
- Pour the mixture into the prepared baking dish then spread into an even layer. Sprinkle the remaining cheese on top then cover the dish with a piece of nonstick-sprayed foil and bake for 60-75 minutes or until the center has set and a knife inserted into the center comes out clean. Remove the foil then bake for 5 more minutes or until the cheese has turned golden brown.
- Let the casserole sit for 15-20 minutes before slicing and serving.
Notes
- If the mixture seems a little dry before pouring into the casserole dish, add another one or two eggs whisked with milk.

Made it on vacation for a group of six. I substituted non-fat Greek yogurt for the sour cream. It was delicious.
Great recipe! Make sure you check your sausage and hash browns to make sure there is not extra salt- I used some that had been salted and put the 1 teaspoon of salt in and it was too salty! Made again with different kinds and it was great! :) Awesome recipe and will definitely make again!
You should really indicate that the sausage and the frozen hashbrowns must be certified gluten free to make this recipe truly safe for those with gluten intolerance or celiac disease. Sausage and hashbrowns are two items that seem gluten free but more often than not, actually contain gluten. If someone were to make this for another person that is gluten free, they may not be as educated in the subject and wouldn’t realize how harmful these two ingredients can be. Otherwise, great recipe, looking forward to trying it!
I forgot all the cheese. It still tasted so good!
Blegh when i asked if my husband what he though he said it tasted sour…like bad milk. I told him itnhas sourcream in it… milk wasnt bad.
Not a yummy recipe. Unfortunately i chose this because i was also making diner for a sick friends family. I can only hop theirs turned out better.
I’m sorry to hear that, Lindy! Is it possible the amount of sour cream was mismeasured?
It looks like someone else asked about the sausage being gluten free and there was no follow up answer, that I could see. Also, people with that type of allergy have to be very careful with foods like sausage because of not knowing what is actually in it. It needs to say (Certified Gluten Free) for those with a strong allergic reaction or at least just say gluten free. If you use a Gluten Free sausage could you please share what brand?
I use Jimmy Dean breakfast sausage, or here is my recipe for homemade breakfast sausage: https://iowagirleats.com/2015/09/18/simple-homemade-breakfast-sausage/
Have you got any breakasts that are gluten and sugar free
How many calories are in one serving of this recipe?
I’m looking for a good egg bake for a bridal shower. Do you have a favorite kind of sausage to use with this?
You have a typo on this page: https://iowagirleats.com/2014/11/21/gluten-free-breakfast-casserole/
” If the mixture seems a little too dry, which another one or two eggs with a splash of milk then add that in.”
Whoops! That should say “whisk” – thanks Jason!
Thank you for the recipe! Can this be made the night before?
