Easy Cheesy Breakfast Casserole

This easy cheesy breakfast casserole is overflowing with sausage, eggs and hash browns. And it can be easily made the night before and baked the next day for breakfast.

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 an 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 until combined.  Then pop it in a baking dish and cook for about 30 minutes.

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

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

Ingredients:

  • 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
  • 2 cups shredded cheddar or mozzarella cheese
  • 1/4 teaspoon freshly-ground black pepper
  • (optional topping: thinly sliced green onions)

Directions:

Heat oven to 375 degrees F.

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.

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 11x7-inch or a 9x9-inch baking dish (a 9x13-inch dish will also work), and top with the remaining 1/2 cup of shredded cheese. Cover with aluminum foil and bake for 20 minutes. Then remove the aluminum foil and bake for an additional 10-15 minutes and the top of the potatoes begin to slightly brown. Remove and let the casserole rest for 5 minutes. Sprinkle with green onions and serve!

    What size baking dish do you use, looks like a 3qt one possibly or is it two? Thanks and looks delicious! 

    • Hayley @ Gimme Some Oven — December 23rd, 2015 @ 9:55 am

      Hi Jesse! The size we used was equivalent to a 11×7-inch or a 9×9-inch baking dish. We hope you enjoy!

  2. laura cooper — December 22, 2015 @ 7:59 am (#)

    It may have been mentioned somewhere in these comments, but I didn’t see it.. What size baking dish are you using? I was thinking about so many people having problems w/ the eggs being runny and thought maybe the dish they were using was too small? With the amount of ingredients, I’m guessing you’d want to use a 13×9 pan?  Thanks!  I’d like to give this dish a trial run today so I know if it’ll work for Christmas morning.

  3. laura cooper — December 22, 2015 @ 8:08 am (#)

    O.k After I wrote my comment, I did actually read over the remaining comments and did indeed see the pan size!! Thanks! 

  4. Jessica — December 23, 2015 @ 9:42 pm (#)

    Just wanted to say that the instructions say 9×9 or 9×11 dish but when I was reading comments you replied to someone and said 9×13. I’m giving 9×13 a shot for Christmas brunch. Sounds amazing. Thanks for sharing!

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 8:52 pm

      Hi Jessica, a 9×9 or 9×11 would probably be most ideal, but a 9×13 should still work. We hope you enjoy this!

  5. Julia — December 24, 2015 @ 2:08 pm (#)

    Can I put the casserole together today and bake in the morning???

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 8:56 pm

      Hi Julia, we wouldn’t really advise that because we worry that making it so far in advance might make it soggy. We hope you enjoy this though! :)

  6. Toni — December 25, 2015 @ 9:33 am (#)

    This was a great way to start Christmas morning! Thank you for sharing!

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 9:10 pm

      Aww we’re so happy to hear that Toni, we hope you had a wonderful Christmas! :)

  7. Adrien — December 25, 2015 @ 10:16 am (#)

    I made this Christmas morning for my family of 4! This 8 serving meal was gone in less than 30 min! Thank you for the wonderful recipe, it was certainly a crowd pleaser!!:) 

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 9:11 pm

      You’re so welcome Adrien, we’re glad it was a hit! :)

  8. Brittany — December 25, 2015 @ 3:38 pm (#)

    Just made this on Christmas Eve to bake on Christmas morning. The only thing I did differently was use bacon instead of sausage and cooked it in a 9×13. It was fabulous! I ate way too much and am about to get another serving for a late lunch. It was seriously so good. I’m sure we’ll be making this lots more! 

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 9:11 pm

      We’re so happy you enjoyed this Brittany, thanks for sharing! :)

  9. Lainie — December 26, 2015 @ 9:26 am (#)

    I made this breakfast casserole for Christmas morning. Wow! It’s just delicious. Thank you for sharing the recipe. I’ll be using it often. So excited to find a morning casserole recipe that doesn’t include packaged flour. And it’s even easy. Oh, yum!!

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 9:21 pm

      We’re so glad this was a hit Lainie, thanks for sharing! :)

  10. Paulette — December 26, 2015 @ 8:44 pm (#)

    Made this for Christmas morning breakfast. It was fantastic. Will now be a tradition to make this each year. Everyone raved about how good it was.  

    • Hayley @ Gimme Some Oven — December 26th, 2015 @ 9:13 pm

      Thanks Paulette, we’re so happy it was a hit! :)

  11. Charlene in MI — December 29, 2015 @ 12:44 pm (#)

    I made this for Christmas breakfast and it was wonderful.  I was looking through the freezer, and realized I had some frozen O’Brien potatoes(potatoes with onions and peppers) and a pound of hot breakfast sausage.  I put both of them in the fridge for a couple of days to defrost, and used those in this recipe.   The potatoes with the mixed veggies saved me some chopping for Christmas breakfast.   I browned off the sausage and drained it on a paper towel since I didn’t need any of the grease for the veggies.  I added a small can of green chiles to the mixture, and subbed out FF half and half for the milk, since I had that in the fridge.  Lastly, I looked through my shredded cheese and realized I was out of cheddar, but I had a Mexican blend.     So as you can tell by the subs, this is a very versatile casserole!  Not only was it great for Christmas breakfast, but my husband has been taking the leftovers to work for his breakfast.  He asked me today if I had any more potatoes in the freezer, and I have already put them in the fridge to defrost.  Sounds like this will be a regular item to make on Sundays for us to take to work through the week.  This is a KEEPER!!!

    • Hayley @ Gimme Some Oven — December 30th, 2015 @ 11:55 am

      Awww, we’re so happy to hear that Charlene, thanks for sharing! Those additions sound awesome too! :)

  12. Ashley — January 1, 2016 @ 8:12 am (#)

    We’re vegetarian so I replaced the sausage with broccoli and I only had shredded potatoes on hand but it came out delicious!

    • Hayley @ Gimme Some Oven — January 1st, 2016 @ 9:26 pm

      That’s great Ashley, we’re happy you enjoyed this! :)

  13. Donald Sherbondy — January 12, 2016 @ 12:54 pm (#)

    Gimme gimme some oven … love that song, but I digress. I love this recipe, I did tweak it a bit though. I added 1 diced green pepper, an extra egg, half sharp cheddar, half Farmers cheese and nearly a cup of half & half rather than milk. Thanks again for the basic recipe … it was mouth watering delicious and I will make it often. I hope you don’t mind my saying how incredibly lovely you are … Henry ‘s one lucky dog!

    Donald

    • Hayley @ Gimme Some Oven — January 12th, 2016 @ 1:28 pm

      Haha! We’re glad you like the song and the recipe Donald! And we think your tweaks sound delicious (farmers cheese is the best)! :)

  14. Lauren — January 14, 2016 @ 4:01 pm (#)

    Hi!

    Could you use fresh chopped potatoes instead of frozen hashbrowns?

    Thanks!

    • Hayley @ Gimme Some Oven — January 16th, 2016 @ 9:55 am

      We haven’t tried that before Lauren, but we think that would be yummy! We’d suggest sautéing them a little beforehand though, just to make sure they cook all the way once they’re in the oven. We hope you enjoy this!

  15. Charlie — January 16, 2016 @ 5:35 am (#)

    My wife & I make this all of the time.  We even sort out into 1 cup portions and pop into freezer and then just remove from freezer and pop into microwave for 2 1/2- 3 minutes & makes for a quick & delicious breakfast. Also much cheaper than store bought ones that you buy in the freezer section of the supermarket.

    • Hayley @ Gimme Some Oven — January 17th, 2016 @ 8:35 pm

      Thanks for sharing with us Charlie, we totally love that idea! And we’re so glad you and your wife enjoy the recipe! :)

  16. Abe — January 16, 2016 @ 8:57 am (#)

    Man was this simple and absolutely delish!! I modified it a bit as my family likes everything HOT! So I added only half the milk and added a can of Habanero Rotels (drained) also melted 1 cup of Velvetta to make it a little chessier and WOW!!! I created a monster! My family is going to make me do this every time we are able to sit down and eat breakfast on the weekends. Thanks sooooooooooo much!

    • Hayley @ Gimme Some Oven — January 17th, 2016 @ 8:26 pm

      Thanks for sharing Abe, we’re so glad you and your family enjoyed it! :D

  18. Rebekah — January 20, 2016 @ 11:06 am (#)

    Thanks for the recipe! I added 6 more eggs to bulk it up a bit but I love how versatile it is. Great use of frozen hashbrowns!

    • Hayley @ Gimme Some Oven — January 20th, 2016 @ 3:11 pm

      You’re so welcome Rebekah, we’re glad you enjoyed it! :D

  19. Tracie — January 20, 2016 @ 3:39 pm (#)

    This recipe looks amazing! Is it okay if I make it the day before and serve it the next day?

    • Hayley @ Gimme Some Oven — January 20th, 2016 @ 8:13 pm

      Thanks Tracie, we hope you enjoy it! And yes, we think you could do that (after you bake it, just let it cool completely and then cover it well before you refrigerate.

  20. Jackie — January 26, 2016 @ 2:33 pm (#)

    Easy is what I like! My family love it. Thanks for sharing!

    How many people does or feed?

    • Hayley @ Gimme Some Oven — February 14th, 2016 @ 7:53 am

      Hi Judy! This should make about 8 servings. We hope you enjoy! :)

  23. Chandra — February 12, 2016 @ 7:58 pm (#)

    Should I cook the hasbrowns on their own first and then add them to cook into the casserole or just add them thawed but not cooked into the casserole dish?

    • Hayley @ Gimme Some Oven — February 15th, 2016 @ 11:36 am

      Hi Chandra! You can just add them thawed to the mixture (last sentence of the first paragraph of the instructions). We hope you enjoy!

  24. Cynthia — March 8, 2016 @ 5:13 pm (#)

    I had breakfast for our group ski weekend.  Chose this casserole, bloody Mary’s, and fresh fruit :).  The casserole was a huge hit (saying lightly)…even the 19 year old got second helpings.   Looking towards the next trip’s menu in a couple weeks…. Hmmmm.  Thank you!

    • Hayley @ Gimme Some Oven — March 9th, 2016 @ 8:40 am

      We’re so glad it was a hit with folks Cynthia! :D

    Do you think you would be able to put this in muffin cups for an on the go breakfast? 

    • Hayley @ Gimme Some Oven — March 23rd, 2016 @ 10:25 pm

      We haven’t tried that Kaitlin, but we love the idea! We think it should work too. If you give it a try, definitely let us know how they turn out! :)

  26. Kate — April 13, 2016 @ 11:24 am (#)

    Can this be assembled or prepped the night before ??

    • Hayley @ Gimme Some Oven — April 13th, 2016 @ 3:45 pm

      Hi Kate! You could certainly prep all the veggies the night before, but we wouldn’t assemble it that far in advance (it will collect too much moisture and will likely get soggy). We hope you enjoy this!

  27. Amy — April 26, 2016 @ 7:50 pm (#)

    Hi!  I made this dish for a Mentor Breakfast for my son’s football program.  I tripled the recipe to fill a 12×17 pan…lots of hungry men to feed. it was a huge hit!  I had many request the recipe.  Sorry I didn’t get to take a picture!  I can assure you I will make this dish again.  Thank you so much for posting your recipe!

    AHMO Blessings to you,

    For those of you that prepared this the night before, how long did you bake it for since it was chilled? Thank you.

    My daughter married in September and moved to Wichita right afterwards. I live out in the country by Wamego and when I read your comments about trying to fit in all the things that we want to do whenever you are together and the spontaneous things that you used to beable to do, it was like tearing a page out of our book. Then there are the other people that she wants to see when she’s back and she’s also working on a dual master’s degree, so a lot of the time she’s either studying or sleeping. But, when I told her about my ideas to make some breakfast casseroles Mothers day and have my siblings and mom come out, she was doubly sorry she wasn’t going to be here this weekend. Our fist mother’s day apart. I’ll have to rub it in about how yummy the food was. Thanks for the recipe it sounds delicious.
