My mom and I were talking the other day about how different life would be if we lived a little closer to one another.

Right now, we live about 3 hours apart — close enough to definitely be able to drive and visit fairly often, but just far enough away that you can’t exactly grab coffee together on a whim.  But that’s what we were talking about.  It would be so fun to just be close enough to grab lunch together spontaneously!  Or pop over for a glass of wine on the back deck.  Or bribe her and my dad with cookies if they’d come help me unload a new sofa.  Or do our grocery shopping together.  You know, the random everyday things…together!

Sure, our time hanging out when they’re here or I’m there is great.  But we usually see each other over the course of a weekend or a few days back-to-back, and you can’t help but feel the pressure to squeeze in All The Things while we’re in the same city at the same time.  It’s like that with any long-distance relationships.  And we both have major roots in both of our cities, so I don’t see that changing anytime soon.  So we talk a lot on the phone, enjoy our time together in person when we can, and make the most of it.  You know, as you do 3 hours apart.  :)

Sadly, I am tied up in Kansas City this Sunday and won’t be able to make it to Wichita for Mother’s Day this year.  But you can bet your bottom dollar that if I lived there, I would love to sneak over to their house early in the morning and make her a surprise to start the day — this cheesy, sausage-y, potato-y, indulgent (and easy to prepare the night before!) easy breakfast casserole.  She would be a little surprised, and she might make some comment about how it’s not quite the light and healthy breakfast she usually eats, and then she would dive in.

Because that’s what moms do.  :)

Yes, this casserole probably falls a little more on the “indulgent” side.  But I have had sooo many requests over the years for a basic breakfast casserole.  And on special occasions, or even just any ol’ day when you feel like a hearty breakfast, this classic recipe is guaranteed to start your day off with a smile.

I have made it (or a version of it) countless times over the years whenever I need a quick and easy meal to serve a crowd.  And I can attest that while it’s a definite crowd-pleaser, it’s also a cook-pleaser because it is super easy to make.  If you don’t want to wake up really early for breakfast, you can also prep it the night beforehand and then pop it in the oven the next day.  Win for you, and a win for your guests (or your mama!).

The steps to make it are simple.  Just brown up some sausage.  (I highly recommend using “hot” Italian sausage, as it will help flavor the whole casserole.)  Then saute some onions, garlic and a red pepper.  (Or you can use a jar of roasted reds.)  Add those together with some whisked eggs, milk and cheese, and toss it all with the potatoes until combined.  Then pop it in a baking dish and cook until the potatoes are tender.

Then once it’s nice and hot and bubbly and melted-cheesy, pull it out.

And top with some green onions, if you’d like some extra color.  Or diced avocados would also be lovely.

Then dish it up (and discover those eggs that have settled to the bottom and baked).

And dive in, just like my mom would.  ;)

So to my mom (who reads my blog faithfully each morning), happy early Mother’s Day!!!  I love you, and think you’re still my #1 Mom, and will make this for you (for realz) the next time I see you.  :)

And to all of you other mothers out there, my warmest wishes to you for a happy Mother’s Day as well!  You are changing this world every day, and we’re all better because of you.  Big hugs from KC to wherever you may be!

Easy Breakfast Casserole with Sausage, Hashbrowns and Eggs

  • Prep Time: 15 minutes
  • Cook Time: 30 minutes
  • Total Time: 45 minutes
  • Yield: About 8 servings 1x


This easy sausage, egg and hash brown casserole is simple to make, and always a crowd-pleaser!



  • 1 pound Italian sausage (I prefer hot, but mild or sweet also work)
  • 1 medium white onion, peeled and diced
  • 3 cloves garlic, minced
  • 1 red bell pepper, cored and diced (or 1 jar of roasted red peppers, drained and diced)
  • 6 eggs
  • 1/3 cup milk
  • 1 (20 ounce) bag frozen hash browns, thawed (I used the cubed kind)
  • 2 cups shredded cheddar or mozzarella cheese
  • 1/4 teaspoon freshly-ground black pepper
  • (optional topping: thinly sliced green onions)


  1. Heat oven to 375°F.
  2. Add the sausage to a medium saute pan. Cook over medium-high heat until browned, crumbling the sausage with a spoon as it cooks. Remove sausage with a slotted spoon and transfer to a large mixing bowl. Reserve about 1 tablespoon of sausage grease in the saute pan, discarding the rest. Add the onion and red pepper* to the saute pan, and saute for 5 minutes until cooked. Add the garlic and saute for an additional 2 minutes until fragrant. (If using the jarred roasted red peppers, wait to stir them until after the garlic.) Pour the vegetable mixture into the mixing bowl with the sausage. Add the hash browns and 1 1/2 cups cheese to the mixing bowl with the sausage and veggies. Stir to combine.
  3. In a separate bowl, whisk together the eggs, milk and black pepper until combined. Then add them to the hashbrown mixture, and stir to combine. Pour the mixture into a 11×7-inch or a 9×9-inch baking dish (a 9×13-inch dish will also work), and top with the remaining 1/2 cup of shredded cheese. Cover with aluminum foil and bake for 30 minutes. Then remove the aluminum foil and bake for an additional 10-15 minutes until the potatoes in the center are cooked through.  (I recommend just using a fork to pull out one of the potatoes in the center of the casserole, and test it to see whether it’s tender and cooked through). Remove and let the casserole rest for 5 minutes. Sprinkle with green onions and serve!


*Update: Some of you have reported back that your casserole took closer to 45 minutes (total) to bake, so I’ve updated the recipe instructions accordingly.  In general, just keep an eye on the casserole while baking, and once the potatoes are tender, it’s ready to go!

  1. With so many eggs, why no salt?

    • Hi Allene! This makes a good size casserole, hence the 6 eggs. We found it doesn’t need salt because of all the cheese, but feel free to add some when you add the pepper!

  2. I was disappointed there was no nutritional value.

    • Hello Barbara! The reason we currently are not publishing nutrition facts on the site is the nutrition calculators available are not 100% accurate, and we never want to publish anything that might be misleading. However, a lot of our readers love the My Fitness Pal nutrition calculator, so feel free to try that for an estimate. We hope that helps!

  9. Could this be prepared in a 3.1qt deep covered casserole dish?would I need to adjust the temp or baking time?

    • Hi Courtney! Yes, it can. And no, you don’t need to adjust the temp, and you shouldn’t have to adjust the bake time. We hope you enjoy!

  10. Hi there,

    Great recipe! Can it be reheated in the microwave? I’d love to be able to take it to work with me but we only have microwaves no oven!

    Thanks :)

    • Thanks, Parris, we hope you enjoy it! And yes, you can reheat this in the microwave.

  11. Can this be made in a crock pot; if so, how long to cook?

    • Hi Kim! We’ve never tried this in a crockpot, so that’s tough to say, but we feel it’s best made in the oven. We hope you can give it a try!

  12. Does this freeze well or keep for a week? Trying to meal prep

    • Hi Brandi! It will definitely keep in the fridge for a week, but we wouldn’t really recommend freezing.

    • I freeze mine cut into one serving size pieces. It warms great in the microwave for about one minute one high!

    Love the recipe! Made it several times already. :)
    Made a few small changes to mix it up a bit. Chicken apple sausage, a little less cheese and added a handful of baby spinach to the veggies. Yum!!

  15. Love this recipe! It is a staple in our family now! Thanks so much for sharing!

    This was a complete distaster. I did thaw the hash browns but after 40 minutes in the oven I finally had to put it in a frying pan to kick start the cooking. Put it back in the oven to finish cooking. Never again will I make this.

  18. Any tips for making it the night before??

    • Hi Mandi! We haven’t tried prepping this the night before, but we think you could definitely go ahead and have your onion, garlic, bell pepper, and green onions (if you use them) chopped, cheese shredded (unless you’re using already shredded cheese) and your sausage already cooked. That’s what we would recommend as far as prepping in advance. We hope this helps!

    I make this all the time when family/friends come to visit. We use breakfast sausage like Jimmy Dean instead of the Italian sausage. Perfect for make ahead, just pop in the oven! Sometimes we serve with tortillas and salsa for “build your own” breakfast burritos, delish! Thanks for sharing this recipe :)

    • Thanks for sharing with us, Jessica — we’re so glad to hear you and your friends and family love it! :)

  20. Going to our kids house next weekend. Think you could make ahead and pop in the oven in the morning?

    • Hi Sev! We haven’t tried prepping this the night before, but we think you could definitely go ahead and have your onion, garlic, bell pepper, and green onions (if you use them) chopped, cheese shredded (unless you’re using already shredded cheese) and your sausage already cooked. That’s what we would recommend as far as prepping in advance. We hope this helps!

  22. Your recipe looks delish. I just wanted to say that I hope you and your Mother can move closer together one day soon. My precious Daughter died in January (2017) from Stage 4 Breast Cancer. We were very close; she was the love of my life. We never lived more than a few minutes from each other, and I thank God everyday for every single second I got to spend with her.

    • Thank you, Sylvia! And we’re so very sorry to hear that. Sending you hugs. Thank you for this reminder that life is so precious and fleeting.

    I want to start off saying that I do not like breakfast food. I made this casserole ahead of time so I could have it in the morning and it was delicious. Very affordable in cost and time.

    • Thanks for sharing with us, Tracy, we’re so glad you enjoyed it!

  24. Hi, looks like a great recipe. I have a question. Can this be made ahead? Like I want to make it for a cottage trip. Just want to have it ready to pop in the oven. Plz let me know if that would work.

    • Thanks, Afsheen! We haven’t tried prepping this the night before, but we think you could definitely go ahead and have your onion, garlic, bell pepper, and green onions (if you use them) chopped, cheese shredded (unless you’re using already shredded cheese) and your sausage already cooked.

  26. Hello! Is there a reason why you made this with Italian sausage instead of breakfast sausage? I can’t stand Italian sausage, but I will use it if you strongly suggest ;)

    This looks delish! Can’t wait to try it on Fathers day!

    • Hi Nicole, no, just preference, you could totally do it with breakfast sausage — it would be very yummy! We hope Dad enjoys! :)

    I made this for Father’s Day brunch today and it was SUCH a hit! So tasty and pretty easy to assemble. I think there were just as many complements as extra helpings of casserole dished out.

  28. This seems easy enough. I would try it out this weekend. Thanks for sharing. :)

    Made this for brunch today along with bloody Mary’s. It was awesome. I folllwed the recipe exactly, no changes needed!

  30. Can I prepare it in the casserole the night before and then cook in the morning?

    • Hi Maria! We haven’t tried prepping this the night before, but we think you could definitely go ahead and have your onion, garlic, bell pepper, and green onions (if you use them) chopped, cheese shredded (unless you’re using already shredded cheese) and your sausage already cooked. That’s what we would recommend as far as prepping in advance, otherwise we’re afraid things would get soggy. We hope this helps!

    I started making this dish without reading other comments. I usually read what others have to say about a recipe to see if I need to make some adjustments. First, I forgot to thaw my hash browns. I figured that I would throw everything together (let the meat mixture cool down before adding the eggs) and toss it in the fridge overnight and that would give the potatoes time to thaw. Then I came to read comments while waiting for the mixture to cool… I saw a lot of questions about making it the day before and that it was unsure if you should or could. Boy was I a nervous wreck!

    Needless to say, it took a little longer to cook (not sure if the potatoes gave off some water while defrosting). I did 35 minutes covered and 15 minutes uncovered (it did start to stick to the bottom). I also used Jimmy Dean Hot sausage. IT WAS FANTASTIC!! My husband said it was a definite make again dish! I would suggest it you are going to make it the night before just make sure your potatoes are defrosted. I think it should be fine.

    We have 3 chickens so we get fresh eggs daily. This will be repeated again and again. I am actually modifying it for dinner tonight. I’m using the hot sausage with taco seasoning and adding green chiles and black beans. Fingers crossed it goes well….

    Love your site! Keep inspiring me to cook more!!

    I am going away for a girls weekend and am in charge of breakfast one morning. I plan on making this recipe but wanted to test it out first so I made it first for my husband and I. I followed the recipe exactly as written but cut it in half since it was just the two of us. I also made it the night before because I’m not much of a morning person and just wanted to throw it straight into the oven. It was super good. I thought we would have leftovers but we ended up eating the whole thing. I’m definitely going to make it for the trip. Thanks for the recipe!

    This was a big hit at our post-Thanksgiving brunch!
    I doubled the recipe, but everything else was just as written, no substitutions. I was a little worried about ‘no salt’, but it didn’t need it, the cheese and sausage were salty enough.
    I used an 11x 13″ casserole dish, and cooked it for about 10 minutes longer than the recipes states.
    I used the hot Italian sausage, but will try something less spicy next time.
    Fed 12 people, and everyone loved it.
    Definitely would recommend as easy and delicious.

    I work in Law Enforcement and I wanted to do something nic for my shift so I doubled the recipe and it was an out of the park hit. Was great for a cool morning before we all had to hit the road and help people. Thank you for the recipe it was so easy!!!!!

    Ali, I’ve made this casserole several times and every time it was a big hit. A previous commenter asked if prepping it the night before would work…..that’s how I’ve made it each time! No problems at all. I love your blog (& I’m not just saying that because I’m a fellow Kansas City-an…ha)! Great recipes😁!

    Made this yesterday for my daughter’s 10am donut birthday party and it was a hit! Made one batch with sausage and another with chopped bacon. They were great!! I did have to cook it about a half hour longer to get the potatoes cooked a little more. Will definitely make again!

    GREAT RECIPE! We’ve started using this as a tradition for breakfast on christmas morning. It tastes great, however it seems to always take about 45 minutes to cook all the way through. What am I doing differently that is causing this?

  48. 4 stars
    I’ve made this 3 times, its very good. But I have to bake it twice the suggested time because my eggs are still runny in the middle after 45 minutes. I have also added green bell pepper.

    This recipe turned out really welll. Had it f

  50. I made this! I think that next time I would definitely season more and thaw the hashbrowns a bit more. I baked it in a 8×8 pan and it took way longer than 45 minutes to cook. When I went to check at 45 minutes, it was still cold in the center and super watery. I kept baking it until the liquid went away but just FYI to those using a smaller dish, it seems to take a lot longer to cook this than 45 minutes.
