This easy Breakfast Casserole recipe is made with eggs, sausage, and cheese and only takes a few minutes to throw together. You can make it ahead of time, so it’s the perfect breakfast casserole for Christmas morning or any day!
Breakfast Casserole
So, I always thought I had the best breakfast casserole recipe (this overnight breakfast casserole that we make a few times a year). I recently learned I was mistaken, because this breakfast casserole right here really is the BEST!
And, although I still really love the other recipe, this one is more of a traditional breakfast casserole, with tons of eggs, and it’s fantastic! Plus, you can still make it the night before so it’s perfect for holidays and special events where you don’t have a lot of time to prepare in the morning.
I adapted this recipe from my sister Jessica over at Pretty Providence. I added a couple extra eggs, some milk, left out the mushrooms and cut the amount of bell peppers in half. The great thing about this recipe is how adaptable it is! It’s delicious with other types of cheese like pepperjack or Swiss, or you could try adding more veggies, like spinach or zucchini.
How to make easy breakfast casserole:
The main ingredients for this egg casserole are really simple and include: eggs, sausage, bell peppers, onion, and cheese. We add sour cream and milk to the egg mixture to make it creamy, light and fluffy.
To make the casserole combine the eggs, sour cream, milk, cheese, and salt and pepper in a large bowl.
Next, cook the sausage, breaking it into small bits as it’s browning. Set it aside and then saute the bell peppers and onions in the same pan. Add everything to the egg mixture and stir to combine. Pour it into a 9×13” pan and bake for 35-50 minutes or until the edges are set and the center is a little jiggly in the center. It will continue to cook and set up as it cools.
After baking, leftover egg casserole can be stored in the fridge and enjoyed within 3-4 days. Leftovers are delicious reheated in the microwave.
Can I make this breakfast casserole ahead of time?
Yes, you can make this breakfast casserole a day ahead, or freeze it to bake another day!
To make one day ahead of time, prepare everything as directed, up until baking. Cover the casserole and store it (unbaked) in the refrigerator overnight or up to one day. Bake in the morning, according to recipe instructions.
To freeze breakfast casserole prepare the recipe and add to your pan. Cover well with plastic wrap and then tinfoil and freeze for 2-3 months. Allow it to thaw overnight in the refrigerator, and then let it come to room temperature before baking according to recipe instructions.

My husband does not like green or red peppers what can I use
Lauren Allen says
You can just leave the peppers out. You could add a cup of hash browns if you like.
Toni says
I didn’t have any peppers so I used one yellow onion and some mushrooms. It turned out great!
Shandra M Uhler says
Put in whatever veggies you want
Cheryl says
Thank you so much for this recipe, what a big hit! Christmas morning was so much easier for me to host and please my adult blended family. I only used 1 lb. of the sausage meat instead of 2 and added a whole green and red pepper instead of the suggested halves. I love this recipe’s flexibility. It was delicious, easy and I will definitely use it again. Thanks and Happy New Year!
Cathy says
We did this for our Christmas morning as well! Now that I’m starting back on keto, I’m planning to make it again as meal prep for my week. What a delicious recipe!
Kassie says

Excellent casserole! Got rave reviews from friends at a potluck and the dish was scraped clean! Blend of flavors was perfect. Will make this again and again. Perfect for low-carb/keto. Thanks!
Diana says
Delicious! I needed to make it a tad bit larger for a carry in. Added 3 more eggs, sauteed 1/2 green, yellow, red, and orange bell peppers, 1 jalapeno, small vidalia onion and added a little more sour cream, milk, and cheese. It was gone in a matter of minutes.
Judy says
Can plain yogurt be used in place of sour cream?
Lauren Allen says
Yes, that’s fine 🙂
Cindy says
Can you cook it in a muffin tin to make individual servings?
Lauren Allen says
Yes, that would work–I couldn’t say the cook time, you’ll have to keep an eye on it!
Tabitha says
Haven’t made this yet, but what would you recommend if i wanted to make this vegetarian?
Lauren Allen says
Leave the meat out and add extra veggies! More chopped peppers, mushrooms, shredded hashbrowns, and spinach would all taste great!
Jeanne says
