Ingredients You’ll Need
Here are a few notes on the key ingredients you’ll need for this easy hashbrown breakfast casserole.
- Hashbrowns: I like to use frozen shredded hash browns. You could also make this with frozen tater tots.
- Bell Peppers: You can use any color you like, except green bell peppers. I like to use red bell pepper so it contrasts with the green spinach in this breakfast bake!
- Cheese: You can make this with cheddar cheese, moneterey jack, pepper jack or dairy-free cheese. I usually make this with VioLife dairy-free cheese.
- Breakfast sausage: Use raw, uncooked ground sausage. I usually use Jimmy Dean Natural pork sausage. You could also use turkey sausage Italian sausage!
I love having a savory breakfast option to go along with something sweet. When we make cinnamon rolls or monkey bread for a special breakfast I always like to serve this hashbrown casserole alongside.
The older I get the more I need protein with breakfast – especially when we’re having a sweet treat! (PS try these gluten-free donuts for a breakfast treat!)
How to Make Gluten-Free Breakfast Casserole
The first step to making delicious breakfast casserole is to cook the sausage and vegetables in a large skillet over medium heat. The onions and peppers in this casserole won’t cook anymore once they are mixed into the the casserole – so I like to get them nice and soft while I brown the sausage mixture.
After the veggies have cooked, add the spinach and let it wilt for just a few minutes. I also love the pretty colors in this casserole with the the red pepper and spinach!
Many breakfast casseroles use soaked bread for texture – but I keep this breakfast casserole gluten-free by adding frozen hashbrowns. They make it hearty and give it a great consistency.
Also be sure to add a good teaspoon salt and pepper when you mix everything in a large bowl so this casserole is flavorful once it’s cooked.
Make it over the holidays or the next time you have a big group of people to feed on a busy morning!
Make it Dairy-Free
This breakfast casserole is also really easy to make dairy-free. I actually almost always make it dairy-free when I prepare this for my family.
I use coconut milk in place of regular milk and vegan cheese in place of sharp cheddar to make this dairy-free. It tastes just as delicious and you’d never know it’s dairy-free with all the sausage and onions/peppers!
For another favorite recipe try these breakfast tacos and banana pancakes!
Make-Ahead Option
Once you’ve added all the ingredients into the casserole dish. You can cover the baking dish with plastic wrap and refrigerate the casserole. The next morning simply remove the plastic wrap and bake as instructed! Serve it with these gluten-free cinnamon rolls or gluten-free cranberry bread for a special breakfast!
I hope you enjoy this sausage hashbrown breakfast casserole as much as we do! PS try topping it with hot sauce!

Could I use cashew mill or oat milk in place of coconut milk in this recipe?
Yes that will work great! Just make sure it’s unsweetened milk of course.
Hello! I’m trying to calculate carbs for an eater with type 1 diabetes. In looking at the nutrition facts panel, are those numbers for 6, 7 or 8 servings (or another number of servings)? Thanks!
Those numbers are for 1/8 of the recipe. I hope this helps!
Hi there! Can you clarify how big a serving is?
Delicious and easy casserole that we enjoyed on Christmas morning! Thank you!
I’m so glad you enjoyed it!
This sounds delicious! Could I substitute 1 pound of cooked, crumbled bacon for the sausage?
Yes that will work great!
This was outstanding. Perfect consistency and flavor. I made it for a work function and it was a hit !
Can this be frozen ahead of time and then cooked ?
I would actually suggest cooking it before freezing. The cooked casserole can be frozen and defrosted overnight then warmed covered in a 325F oven for 20-40 minutes until heated through.
Can this e made with Soutwestern Style Egg beaters??
Hi Erin.
I am considering making your Sausage Hashbrown breakfast casserole this weekend.
I intend to assemble and refrigerate overnight, before baking the following day.
It has been suggested that frozen hash browns should be thawed before adding to a casserole for best results, However, your recipe does not suggest this so I’m not sure.
Also, if I decide to use cubed gluten-free bread instead of hash browns, how many cups would you suggest?
Hi Kathie – you can make this ahead of time and refrigerate no problem! It will work if the hashbrowns are frozen or thawed – either way. I don’t recommend swapping GF bread in for this recipe. I haven’t experimented with it myself and suspect it might be too soggy.
Delicious and so flavorful!
Do you think using freshly grated potato would work?
I could only find sweetened condensed coconut milk. Will that work?
No that won’t work at all! That’s only for desserts as it has added sugar.
Could I make this the night before, refrigerate and bake in the morning?
Yes that will work great!
Hi Erin,
Thanks for this recipe! Can you recommend a good non-diary cheese substitute brand? I have a guest coming you can’t eat dairy. Thanks again. =)
Yes! Lately I’ve been liking VioLife dairy-free cheese. I hope this helps!
I made this with unsweetened Almond Milk and turkey sausage. Also replaced the spinach with portabello mushrooms, as I had some of those in the freezer. The ladies at my brunch loved it! It was a bit tangy and in the future I’ll make again but leave out the salt and pepper. Would anyone know the nutritional values with the turkey sausage and almond milk?
