Sausage, Cheese, and Potato Egg Casserole-this easy breakfast casserole feeds a crowd and can be made in advance. It is perfect for holidays and get togethers.
We have family coming in town for the holidays and we are so excited. My dad is coming and Josh’s brother and his family are coming. There will be six boys, all five and under. It is going to be a fun and wild time. I am starting to plan what food to have on hand and this easy Sausage, Cheese, and Potato Egg Casserole is on the list. I know all of the boys will love it!
I love breakfast casseroles because they are easy to make, can be made in advance, and feed a crowd. Plus, the leftovers reheat well. I don’t know if we will have any leftovers this time around since I am feeding a houseful of boys, I am sure they will devour this casserole.
This easy egg casserole is filled with sausage, cheese, breakfast potatoes, red pepper, onion, and spinach. I like to sneak in the spinach, my boys don’t even know it’s there:) This is one of their favorite meals.
If you have company coming for the holidays, I highly recommend you make this Sausage, Cheese, and Potato Egg Casserole. It is great for Christmas morning or any morning. And it will go great with my dad’s cinnamon rolls. My dad makes them every year and we can’t wait to be spoiled with his famous cinnamon rolls! We are going to have a fun and delicious holiday!

Ingredients
- 1 lb. breakfast sausage
- 1/2 large yellow onion diced

Ahhhh, love breakfast casseroles! This looks great Maria!!
Now this is how you do Christmas morning breakfast!!
What a tasty breakfast!
So, mighty peas, love to look at your beautiful and yummy recipes everyday. One question about the casserole, is it possible to bake it in silicone cupcake cups and freeze for a time? Would love to serve these to a big group in the future. Keep up the good work all, and enjoy your holiday adventures. Heartmathchef
Thanks! Yes, you can make muffins. Enjoy!
Six boys! there will be a lot of action in the house! This looks awesome!
hey girl – this looks really good!
This is amazing!.Our family has made it regulrly for the past few years. I have also made it for work. Everyone loves it.
I make a frittata almost just like this almost every week, and always on Christmas morning! I can’t wait to try this one =)
Silly question, but can you use regular potatoes that you cut up yourself?
I make a casserole like this but use regular potatoes. What I do to is microwave the potatoes first so they are basically pre-cooked. The casserole isn’t in the oven long enough or on a high enough heat to cook the potatoes until soft otherwise. I microwave for about 7 mins, with potatoes cut up into small cubes, and that makes them perfectly soft and ready to add into the dish.
My son won’t eat sausage (or any ground meats,xcept hot dogs). Could you sub bacon instead? This recipe sounds delicious! I hope you have a wonderful Christmas!
Yes, bacon would be good too!
This looks super delicious! Would love to start our weekend off with this!
Would this recipe work with shredded hashbrowns?
Sure!
This looks fabulous. I’m vegetarian, so can’t add the sausage, but will definitely be trying this with vegan sausage. Your photos are gorgeous too 🙂
Thank you!
Just a note for vegetarians (and others who might enjoy this switch): If you have a Trader Joe’s in your area, they have a delicious vegetarian chorizo. I made this recipe and substituted the chorizo for the sausage, and it is great! I will definitely be making this again.
You won’t eat meat but you will eat chicken babies?
Did he say baby chickens? unfertalized eggs are not baby chickens! Lord science.
Hi Maria!
Could you use less milk, use a substitute milk product or leave it out all together?
You can use almond milk.
thank you for this, used to have a version of this in our family, but somehow lost in the past, so this is very helpful and great time of year for a easier serving breakfast like this!
This looks amazing! I need this in my life… and in my breakfast routine!

We love egg casseroles here!!
I make frittatas all the time, which are pretty much the same as casseroles. I’ve never actually made a casserole! Why I choose to strictly make frittatas baffles me – maybe it’s because of my Italian heritage?! 😉
Would I freeze it after cooking it? I’m concern I won’t have the fridge space and will need to make it ahead. Help!
Yes, you can freeze the casserole.
Cooking now – been in the oven for an hour and still a bit runny. Even had to bump the temp up… hoping it turns out ok. Smells good:)
This was delicious! ! My kids aren’t fans of spinach so I left that out but the whole 9×13 pan was gone in one sitting. I will defintley make this again.
When you say “frozen diced potatoes”, are you referring to hash browns?
yes
I’ve used frozen hash browns in other b-fast casserole recipes (not yours) and they turned out mushy. Has this ever happened to you when using frozen hash browns???
No, we use frozen potatoes, the diced potatoes, not the shreds. Maybe that is why?
I want to cut this in half, bake in a 8 x 8 dish. Suggestion for baking time?
How many days will this last once cooked? Thanks!
You can keep it in the fridge for up to 5 days. You can also freeze the casserole for up to one month.
i think this dinner is going to be really yummy.
What’s your recommendation for baking in advance and re-heating? Could I keep it refrigerated after baking and then just pop it back in the oven whole for a few minutes when we’re ready to serve? Thank you for the recipe!
Yes, that is perfect! Enjoy!
I like this kind of food very much. It’s nutritious and healthy. Children like to eat this kind of breakfast
Absolutely delicious! Planning on fixing it again!!
I have made this casserole many times for other people and have had rave reviews. I would love to try it myself but can’t do egg yolks… can I make this with just egg whites?
Sure, you will just need a lot more:)
This is a very tasty and light for an egg casserole.Flavor and aroma are both very good! and the Pepper Jack takes a back seat – no one commented that it was ‘spicey’.
I made a couple of changes:
substituted sweet potatoes for the diced frozen potatoes
Substituted 1/4 cp Coconut Cream + 3/4 cup water for the milk
Reduced the salt to 1/2 Tsp
Hi, just wondering if I can freeze this recipe, or if not, would it be good if it would be made 3 days ahead of eating?
You can keep it in the fridge for three days and reheat or you can freeze it. Of course, it is best fresh, but you can reheat it!
Very tasty breakfast casserole. We found the 2C of pepper jack cheese to be a bit too spicy for our taste … but a mix of 1C pepper jack and 1C Monterey jack was perfect. Thanks for sharing a great recipe!
We just had this at a graduation brunch – it was awesome! I had several people asking for the recipe. I’ll definitely be making this again!
can this be made in a crock pot
I haven’t tried it!
So, this morning I could not find my usual egg bake recipe and went looking for a new one. Finding this one, I was pleased with the ingredient lineup and made it forthwith!
My recipe has more of a southwestern flair and so this is a welcome divergence. I changed a couple of things. 1/2 lb more sausage — 1/2 tsp less salt — 1 tsp black pepper — 6 green onions. This recipe is fantastic! Definitely a do again. Thanks for posting it!
Can I use a 1% or skim milk for this recipe?
Yes!
We don’t eat potatoes, would you just leave them out?
I make this regularly! My whole family loves it. This is the perfect breakfast casserole!
Delicious! So tasty plus easy. Now in family menu rotation.
OOPS! Meant 5 stars:)
I can make this the night before hand, and cook in the morning?
New meal prep fav!
Yahoo!
We made this delicious casserole for New Year’s Day breakfast. It was soooooo good! Definitely making it again!
I’ve been using this recipe for years now, for the last 5 or 6 years it’s become a christmas tradition for me to cook this when my mom and brother come over to celebrate. And we cook it at least once every other month and love it! We forgo the spinach and green onions, but the red bell pepper really does make a difference versus green pepper. Highly recommend!
Glad you love it!
We tried this recipe this week and it was liked by all! If you want to freeze it, would you freeze after baking? Then thaw in the fridge before reheating? Thank you!
I freeze some for easy breakfasts, or school lunches. It does freeze well. I cut them into servings and freeze them in a freezer bag.
I’m making this for houseguests on Sunday! Can I substitute unsweetened ealmond milk?
Yes!
Just made this for an early morning Game of Thrones viewing with friends by their pool. They raved about the casserole. I think the exact comment was, “ This is all kinds of good eatin’”. Being the Cajun in our group, I like food with a little kick. I will definitely make this again!!! Thanks for the recipe!
-Amy from Texas
can’t wait to make this for Thanksgiving morning – can I use sharp cheddar instead?
Yes! Enjoy!
5 star we just made this… tweaked it for our experiment and taste bus added mushrooms bell peppers sage sausage then garnished with hot peppers yummy
How many servings does this make?
It makes a 9×13 pan, so I would say 12.
Can I use fresh potatoes?
Yes, I would cook them a little in the microwave or on the stove to soften them up a little before adding them in.
I made this tonight for my family of 4! I prepped this AM and put in oven dinner time. I didn’t have spinach so I put tomatoes and I didn’t have frozen potatoes so i diced and partially cooked before I mixed in. It turned out AMAZING and my family loves it. I do as well and I’m not an egg fan but I’ll try to eat one or 2 for nutrition purposes. I also used almond milk! Thank you so much, this is a keeper ✌ ❤
This was an excellent casserole, definitely a keeper. Can someone post the nutritional content.
haven’t eaten it yet
I’m looking at making this in cupcake wrappers for a brunch. How much would that change the cooking time?
Spray the wrappers with nonstick cooking spray so they don’t stick. I would check them at 18 minutes to be safe. Might take a little longer.
I just made this and it is spectacular even though I only used a 1/2 up of cheese and 1 cup of sausage. It’s what I had on hand. Solid reciped. I also didn’t have frozen potatoes so I just pre cooked some in the micro and threw them in. I will be making this again for company.
thanks for posting this recipe.
I have made this multiple times and everyone loves it! So easy to prepare and so delicious! Definitely one of my favorites!
Could I sub frozen hash browns for the potatoes?
Sure!
This is one of the best breakfast casseroles I’ve ever had. I’ve made it for a number of social gatherings and it is always a crowd favorite. I’ve made it the night before or the day of and it always turns out great. Thank you so much for a family favorite recipe!
ok but I won’t make it again
This recipe is really good!
I normally hate egg bakes but I made this version and I could not stop eating it. it is also a really simple recipe to follow.
Can I use box of betty crocker Julianne potatoes instead of the frozen diced potatoes?
That should be fine. I haven’t tried that brand.
can i mkae this with cut up potatotes? Not frozen? I have a bunch of baking potatoes.
Hi….quick question, for the breakfast sausage, do you cook them whole then cut in pieces to add to casserole or take the meat out of the casings then cook?? I’m making this for a brunch this weekend!! Can’t wait!!
Great recipe, but I needed to modify it a bit becasue I didn’t have items on-hand.
I used 3 fresh potatoes, diced and fried them with the sausage, onion, bell pepper for 15 mins. Also, I used garlic salt instead of fresh, and skipped the spinach. I baked it until it was a golden brown and topped it with fresh jalapenos. SO GOOD!
How many catbs fadt and calories per serving
Excellent recipe, very simple to make, everyone loved it, the only thing I did differently was I unthawed my potatoes.
If you unthawed the potatoes they’d be frozen….
Can I pre-bake then freeze and heat when needed?
Yes!
Delicious!!!
Thanks!
Thanks for this delicious recipe. Made this Christmas morning and it was terrific. Leftovers today are even better! I didn’t have green onions but it was still plenty tasty. My husband was talking about variations of this recipe that he would like me to try, too, with different kinds of sausage and veggies. Would be great for dinner with a side salad. Also made your candied pecans recipe again and gifted them – also a hit. Keep these wonderful recipes coming!!!
Awesome!! Glad you are loving our recipes.
I made this for our family Christmas breakfast and everyone loved it. I followed recipe exactly but cut back on the onion. ( I am not a lover of onions but know they are a must in cooking). I made it the night before and baked it in the morning. It came out great. I wanted to say we love your Dad’s sweet rolls. Yummy.
I am glad everyone loved it!
Thanks for the recipe. It came out pretty good and looking very similar to the photo, but I like to wing it and use the ingredients that I have available, and so, instead of using spinach, I used one leek stalk, and I had fresh potatoes that I wanted to use, and so I peeled three large potatoes, wrapped them in wax paper, and cooked them in the microwave, about three minutes each if you do it individually. The red pepper I had chopped in advanced and put into little baggies in the freezer. It probably only came out to about 1/4 of a large bell pepper, but it was enough. I used the Johnsonville Italian sweet sausage, about 12 ounces, and that was plenty; I kept on grinding it down to small pieces with a spatula. Some of the bottom and sides got almost too browned, but you can easily scrape it off with a fork. For seasonings, I used Italian seasoning, Garlic powder, freshly ground black pepper, some table salt, maybe a little paprika, and a few drops of Worcestershire sauce. Let’s see, what else did I do differently. I used only about a half a cup of milk, and I used a Vidalia sweet onion which I threw in with the leek and the sausage and the red pepper with seasoning and sautéed in a pan in advance. Perhaps next time I will use more cooking spray and smear it more evenly with a napkin. That might work. But all in all, it came out pretty good. It smelled really great when taking it out of the oven. I ate five pieces, and my stomach is still busting.
I also used dried chives. After it came out, I sprinkled some salt, ground pepper, and some more chives on top.
If anyone wants to use my variation of this dish, I call it Jeff’s Baked Frittata. Thanks again two peas in a pod.
Excellent recipe. My family loved it. We had breakfast for dinner. I added green bell pepper and didn’t have pepper jack cheese so used Mexican blend and added in a little bit of red pepper flakes. Definitely will make again.
Do the potatoes have to be frozen?
No, but make sure they aren’t soggy.
Wonderful. Making it as written for the third annual visit to the creek for our young friend. So delicious.
This looks yummy. When you make it in advance, do the potatoes get discolored?
I haven’t noticed them an odd color.
