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 Cheesy Breakfast Casserole Recipe

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 will 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 diced hash browns, thawed
  • 2 cups shredded sharp cheddar 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!

    This recipe was wonderful, my husband loved it. Very easy to prepare. Great when you want something different.

    This recipe is a breakfast staple in our home. Friends come to spend the night? Something special to celebrate on a Saturday morning? Or just in need of some delicious comfort food, this recipe comes out. Throw it together in a flash, and its incredibly delicious.

    This is a great base recipe, and easy to adapt to whatever you’ve got hanging in the fridge. I didn’t have sausage. I did have some leftover ham steak from yesterday’s breakfast though. And I used the mozzarella I had left from pizza night. And then there were the leftover frozen shredded hash browns taking up too much space in my tiny freezer, and the 3-day old leftover cut bell pepper. The onion became a shallot, and the milk was the last of my fat-free half and half. It came out sort of like a western omelet. The eggs were eggs. :) I kept all the measurements the same. Seriously good. Would definitely make again, with whatever is handy.

  6. Making this for a crowd tonight :)

    Made this for Easter breakfast, the proportions are way off, too much potatoes not enough egg. I added more eggs and it was still dry and all potato. I would do 1/2 the potatoes to 8 eggs.

    I have made this casserole several time and it is always a crowd pleaser. It’s so easy to make and is delicious. You can use the cubed hash browns or the shredded ones it doesn’t matter. Try it. It will be a favorite.

  11. The pictures of this casserole look so enticing. I am going to have to try it. We eat strict kosher though so I will substitute veggie sausage. I hate casseroles that are too “eggy” and this one doesn’t look like that. I will post after I make it.

    Thank you

    This recipe is fabulous. I love to make breakfast casseroles anytime I serve brunch to a crowd and I’ve been dying to find one that doesn’t use some sort of boxed bread product for bulk. I have nothing against boxed items but I sometimes find that everything tends to taste like that item once I add it to a dish. This is ease to make, delicious and it feeds a crowd. I’d recommend hot sausage every time. And don’t skip the green onion sprinkle if you like them.

  14. I’m going to make this tomorrow morning as it sounds scrumptious. You are so lucky and blessed to have your mom and the best part is you appreciate her!

  15. 5 stars
    Thanks! This is such a great recipe! I also like to add bacon to this either in addition to or instead of the sausage. I also like to pre-cook the potatoes a bit in the pan before mixing them in. I know it’s an extra step but it adds so much more flavor and it also lessens the bake time.

  16. I’d like to make this the night before, but I’m not sure how to do that? Would I fully cook it in advance? If so, how do you recommend heating it up the next morning (in the oven for how long? with or without tinfoil?) Or do I not cook it, and just assemble it, and fully cook it in the morning? Or should I just microwave it to warm up (does it taste okay reheated)? Sorry, so many questions!

  20. I make this often, I have modified by using potatoes o’brien and it turns out delicious.

    Anyone I have made this for loves it. When guests come in town they usually ask if I’m going to make that breakfast casserole again (and they mean this dish). It’s very yummy and easy to make it your own. Such as, I always add jalapenos to it.
    I usually prep everything the day before so in the morning I just have to combine ingredients and bake.

    This casserole is awesome! I don’t eat beef or pork but I’ve prepared it four times for groups of people and they absolutely love it! The only thing I’d change is the pan size. The 13×9 is too large iof a pan for my preference. I’m sticking with the square 9×9 as I prefer a thicker casserole. Awesome recipe!!

  24. Hi, I would love to make this ahead of time and freeze it for when a group of us go away. Any tips? Thanks!

    I used my cast iron skillet for onions and half the potatoes to cook almost completely. Bulk breakfast sausage cooked separately. Put together p in skillet, added 8 eggs, milk and cheese, roasted red pepper and a few pepper flakes. This is a really good and easy recipe that you can modify any way you want and it will be great!

    Made it for meal prep for breakfast every morning to take to work. So good! The Italian sausage makes the flavors pop!

    This recipe was included in a list of breakfast casseroles that my husband— a brekkie fanatic— sent me. Turn out delicious! I did find that it took closer to an hour to cook, but that’s no problem. Was also tickled to see that the recipe comes from a fellow Wichitan!

    It will be our new Christmas morning staple .

    I made this casserole for Christmas morning and it was a hit! I used shredded refrigerated hash browns (the whole bag) because that’s what I had and they worked well. I enjoyed the simplistic nature of this recipe and will make it again next year.

    Love the receipe and my husband loved it even told me it was really good after breakfast and he almost never compliments or complains about what is cooked, you go by how much of it he eats.. just not him so when he does it is awesome! I changed the frozen potatoes to some fresh I needed to use…. 2 1/2 cups diced if anyone wants to know that. Thanks 😊
