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

Description

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


Ingredients

Scale
  • 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

Instructions

  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!

Notes

*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. Tried this recipe for the first time today. I used shredded potatoes and it was very good. The next time I think I’ll use pepper jack cheese as well as top the dish with crumbled bacon.

  2. This is delicious!! Can you share the nutrition facts?

  3. I tweaked it a bit. I used 1/2 lbs breakfast sausage, 4 strips of bacon chopped, and ham pieces. I used green peppers instead of red. I had shredded hash browns instead of using potato cubes and baked covered for 30 mins. DELICIOUS!

  4. I made this an overnight casserole, prepared it the night before and set it out for half an hour before putting it in the oven. It needed to bake for an hour and twenty minutes. The last half hour w/out the foil. I did bake it at 350* instead of 375*.

  5. This was delicious! We used fresh red potatoes and didn’t need to adjust the cooking time at all.

  6. It’s really delicious and so easy to put together. It would be good for any meal.

  7. Very yummy! Only thing I do different is double the meat because my guy loves meat! A++

  8. Made this recipe for the first time and it was delicious! I topped it with salsa verde as I served it and really added good flavor. Would definitely make again!

  9. Outstanding! Only thing I changed was I used 8 eggs. 6 seemed a little lonely in that big mixture

  10. I love this recipe. I use a dozen eggs .take about a hour.

  11. I haven’t cooked this yet, however my son made it at our Thanksgiving Weekend. It was delicious, he made a extra large dish and almost all of it was eat. When we started home they sent it with us. The next morning I warmed it up for breakfast for me and my husband. It was still delicious.

  12. I made this for my family and they loved it.

  13. Can this recipe be made in the microwave? I won’t have access to a conventional oven on Christmas morning, when I usually make a strata (prepared night before then baked in the morning in a bain-marie in the oven) for breakfast.

  14. Have made this several times and have added a couple ingredients that my kids like. We added a cup of cubed ham and 2 cups of broccoli. Made it per the directions the first couple times and it has been a family favorite ever since. Thank you 😊

  15. I made this using garlic smoked sausage. I added a teaspoon of tastefully simple spinach and herb and a 1/4 teaspoon of red pepper flakes. It was awesome!

    • Didn’t see “Salt” in the ingredients. So i trusted the process and said to myself, maybe all the flavors will release natural salts and wont need any. Boy i was wrong. The casserole in general was so good and packed with flavor after i sprinkled some salt on top of it. My mother loved it, she requested that i make it again for Sunday brunch. Will deff add my own spices but deff will use the same recipe! Thank you💕

  16. I am attempting to make a layered casserole.
    I have 8 baked potatoes left over from xmas dinner. Will use what I have. I will brown 1 lb ground sausage and 10oz chorizo and chopped onions, which I will layer over the cut up potatoes with skin on. Then I will pour doz scrambled eggs over mixture salt and pepper pinch of salt. I will then add shredded cheese on top. Top it with green onion once out of oven. Hoping it comes out integrated and layered. Wanted to add bellpeppers with chopped onions but, alas, have none.
    Yours reminds me of homemade cornbeef hash from yrs ago.

  17. Easy to make casserole with so much flavor! Made the night before with exact ingredients. Bake for an hour in e morning – first half hour covered with foil. Delicious!

  18. Just made this, and it was delicious. I made a few substitutions based on what I had on hand, the main one being that I didn’t have any bell peppers but I did have chili peppers and mushrooms. One note: if you’re substituting fresh diced potatoes for the frozen hash browns, consider parboiling them before adding them—it took a long time to get them baked all the way through.

  19. I am looking for something I can freeze for a new mama to reheat. This should work, right? I’ve never made enough to freeze!

    • I have frozen this to take to my daughter’s house! Just thaw overnight in the fridge, let come to room temp (about 1/2 hour) and bake as directed! My grandkids loved it and my daughter was so happy she didn’t have to cook! :-)

  20. I followed the recipe exactly and mine looked nothing like the picture shown. I used a 9×13 pan. It was quite full. I honestly wonder if this blogger even made this recipe since all the posters had to tell her it takes atleast 45 mins to bake..it was quite tasty..I will add more sausage next time

  21. This was so good that my son in college has asked me for this recipe! Go figure!

  22. It needs to cook 1 HR to 1HR 15mins. We also added bacon and added double eggs it was great. Will be making again

  23. Best recipe ever. Use the hot Italian sausage. But replace the potatoes with frozen tator tots!

  24. I’d advise to cook the hash with just a spoonful of bacon grease or oil. The potatoes will look dry towards the end but stir it here and there and it will get a good head start.

  25. Made this for a Birthday breakfast party and everyone loved it! I did add salt .

  26. Bomb-diggity. Spot on with everything. Did not use bell peppers. Easy and a hit!

  27. Decent, easy to make crowd pleaser! This is one of those simple recipes that lends itself to personalization so I add a little onion and garlic powder to the whisked eggs for just a little more flavor in them, otherwise the sausage carries most of the flavor. I also like to use half and half with the eggs for a little more richness.

    Don’t be afraid to try different meats or cheeses if sausage and cheddar aren’t your thing! This would be excellent with ham and Swiss cheese!

  28. I made 1/2 recipe, as there are just 2 of us. Didn’t have used French fried cut up:) it was really good!

  29. can this be made cooked then frozen?

  30. I suppose it wouldn’t be fair to rate this any lower, because I did make some changes, but there was way to much onion for my taste. It completely overwhelmed all the other flavors. I used 12 eggs, bell pepper and onion as instructed, breakfast sausage, added 2 cups of broccoli, and shredded my own potatoes. Still, all I could taste was onion. Baked for 1.5 hours at 350. If I make it again, I’ll omit the onion entirely.

  31. As you stated in an update, this definitely takes at least 45 minutes to cook and I’m currently at an hour-and-going to get the center set and the diced fresh potatoes cooked. The active prep time also took me way more than 15 minutes and I’m quite efficient in the kitchen. I wish recipes included a range of prep time based on experience for a more realistic time range. Or maybe it would be 15 minutes if someone was using all pre-cut/shredded ingredients. Although I suppose the time listed technically does start after all the ingredients have been prepped. So long rant short, the actual time for this dish is probably 1.5-2 hours.
    Still yummy, and gimmesomeoven is still a go-to recipe site for me!

  32. Made a beautiful Easter Breakfast! Cooked it in the oven in a cast iron skillet. Put in oil while the oven preheated. Added the thawed hash browns while I finished browning the sausage and egg mixture. Once all components were ready, I added the sausage/veggies on top of the potatoes. Then added a layer of cheese then poured the egg mixture on top and baked. Cut the cooking time down significantly!

  33. If you use a frozen bag of hashbrowns, onions and peppers, it’s much easier.

  34. Easy and tasted great! I bought the frozen diced potatoes with the peppers and onions in them. It did take about 50 min total to bake. A crowd pleaser!
