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 with the potatoes 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!


  • 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)


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!

    How many does this serve

    • Hayley @ Gimme Some Oven — June 17th, 2016 @ 1:16 pm

      Hi Charlotte! This makes about 8 servings. We hope you enjoy!

  2. Paul — July 5, 2016 @ 5:40 pm (#)

    Make it real good by pouring sausage gravy over the top of it, my son went nuts eating this.

    • Hayley @ Gimme Some Oven — July 6th, 2016 @ 9:16 pm

      That’s awesome Paul — we’re so glad he loved it! :)

  3. Katie — July 18, 2016 @ 4:35 pm (#)

    I’m making this for dinner tonight and I cannot WAIT to try it!! 

    • Hayley @ Gimme Some Oven — July 18th, 2016 @ 9:57 pm

      Awesome Katie — we hope you love it!

  4. Flo — July 20, 2016 @ 3:58 pm (#)

    What is the nutritional breakdown? Why do you not make this information available? Looks good, just hoping it is not too caloric.

    • Hayley @ Gimme Some Oven — July 21st, 2016 @ 12:10 pm

      Hi Flo! We’re sorry but the reason we currently aren’t 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!

  5. Ruthann — August 20, 2016 @ 2:27 pm (#)

     just wondering, can you make this I had of time and mix it all together except for the 80s and keep it in the refrigerator overnight and then in the morning at the eggs and cook it 

    • Hayley @ Gimme Some Oven — August 21st, 2016 @ 4:15 pm

      Hi Ruthann! Yes, we think it would be fine to mix everything together ahead of time (except for the milk and eggs). We hope you enjoy!

  6. Marci — August 30, 2016 @ 9:43 am (#)

    Have you ever made a double or triple batch in a larger pan? If so, do you know how long I would need to bake it?

    • Hayley @ Gimme Some Oven — August 31st, 2016 @ 2:46 pm

      Hi Marci! We haven’t tried that so it’s difficult to say. However, because of the larger volume, it will take longer, it’s just hard to say how much longer. We’d recommend setting the timer for 25 minutes and then checking it every few minutes after that. Definitely let us know how it goes! :)

  7. Sarah — September 14, 2016 @ 9:35 pm (#)

    Do you find that this casserole reheats well? I’m trying to make this and divide ho for a quick reheat and go before school in the morning. 


    • Hayley @ Gimme Some Oven — September 16th, 2016 @ 12:44 pm

      Hi Sarah! Yes, this definitely reheats well. We hope you enjoy!

  8. Kari — September 16, 2016 @ 1:55 pm (#)

    I bet this could be cooked in muffin tin too for individual servings making it easier to reheat and go. Would just need to adjust cooking time.

    • Hayley @ Gimme Some Oven — September 16th, 2016 @ 3:11 pm

      Yes, we think you could definitely do that — great thinking! :)

  9. McLemore — September 17, 2016 @ 11:40 am (#)

    I used frozen Potato O’Brien to make it even quicker and easier. Omit onions garlic and red pepper and add 1 tsp. garlic powder, 1 tsp. onion powder and the thawed O’Briens.

  10. Mackenzie — September 17, 2016 @ 2:20 pm (#)

    Made this for my gluten free brother/sister in law and it was super tasty (though I did add some pepper jack cheese, parsley, and ground mustard). I can’t imagine it only taking 30 minutes total to bake though!! I put mine in a baking dish that looks a lot like the one in the pictures and it took over an hour before all the potatoes really felt soft/cooked to me. Then again I WAS thinking that the potatoes in the pictures (though beautiful pictures haha) do look like they are kind of crunchy. But to each her own. :) I will definitely make this again and put it in a larger dish to bake for around 45 min probably.

    • Hayley @ Gimme Some Oven — September 18th, 2016 @ 6:37 pm

      Hi Mackenzie! We’re glad you enjoyed this, but we’re sorry it took you so much longer to bake! We wonder if the baking dish you used was a little smaller? Or maybe the potatoes were sliced a little thicker?

  11. Sue — October 1, 2016 @ 11:41 am (#)

    The potatoes look more like O’Brien styled potatoes rather than hash browns… I will be making this tomorrow morning to watch for our morning football game.

    • Hayley @ Gimme Some Oven — October 5th, 2016 @ 1:25 pm

      We hope you enjoyed it, Sue! :)

    Love the blog. Just a heads-up..in your description you say

    “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.”

    Looks like you left out the potatoes! Just my observation. About to cook this now :)

    • Ali — October 12th, 2016 @ 6:08 pm

      Whoops – typo! Thank you! :)

  13. Lisa — October 9, 2016 @ 11:05 am (#)

    Have you e very used  Flour tortillas and filled them with this?  Trying to take to work tomorrow for a breakfast 

    • Ali — October 12th, 2016 @ 4:30 pm

      I haven’t, but I’m sure it would be delicious! Breakfast potato burritos! :)

  14. Betty Jaeger — October 19, 2016 @ 3:52 pm (#)

    Have you ever made this with pork sausage? If so, would you recommend it?

    • Hayley @ Gimme Some Oven — October 24th, 2016 @ 1:24 pm

      We haven’t, but we think that would be delicious (especially if it’s a country-style pork sausage)! :)
