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!

  1. What size casserole dish did you use?  This looks delicious but im wondering if a 9×13 will be too large?

    • That is slightly bigger than the dish I used, but it would still definitely work. You might just need to cook it a couple of minutes less. Enjoy!

  2. I might have missed it but what size casserole dish are you using?
    I’m having a brunch for 10-12 people Saturday morning. I’ve been looking for a recipe I can make the night before and put in the oven in the morning. Wouldn’t the dish have to be OK to go from the refrigerator to the oven. In other words, I couldn’t use a clear pyrex dish, correct?

    • My dish was a little smaller than 9×13-inch (closer to 11×7-inch proportions), but either size dish would work. And yes, I would let the dish at least heat up to room temp if you’re using a glass dish and transferring it to the oven. Or use a metal dish if it needs to be a quick transfer. Enjoy!

  14. Can i cook and refrigerate overnight and warm in the morning?? I want to make it ahead of time then bring it for Christmas morning  

  15. I’m making this for breakfast on Christmas morning (in a few hours). My local store only had shredded potatoes, so I hope it still turns out good. 

  16. I made this yesterday and it is amazing! I enjoyed it as a casserole, but this morning I wrapped up the leftovers in some flour tortillas and it was even better that way. Thanks for the awesome recipe, I’m going to be making this one a lot! =)

  18. Just lost my mom. Good news is she lived with me.

    You may think it would be difficult to move; but I know that you would NEVER regret it. In fact, if you don’t, you will probably regret it. Better to be 3 hours away from your friends than your mom. The fact is is that you only have one mom and once she is gone, she’s gone.

  19. I made this tonight for my family of 4 and literally there wasnt a drop left. EXCELLENT!! thanks for sharing.

  20. Howdy from Lawrence! Am trying this for breakfast tomorrow because it doesn’t sound like I’m going to want to leave the house tomorrow due to the weather. Have you tried this with chorizo? 

    • Hey in Lawrence! I have not tried it with chorizo, but imagine it would be amazing. Just be sure to drain the chorizo! :)

  25. Looking forward to making this for tomorrow morning.  Planning a busy and hard working day and need to start with a strong breakfast.  My parents will be helping us install flooring this and next weekend.  No bribing necessary, just a lot of love.  My mom and I have been having lunch together at least once a week for over 10 years.  It’s the best.  Plan to continue with my girls.
    By the way, I’m planning to make it tonight and cook it in the morning.  Will the eggs at the bottom mess it up sitting all night?  I’m not used to making things ahead.

  31. I was wondering if you could bake this with biscuits on top and make sausage gravy with the sausage drippings to pour over the top after its done cooking. Sounds good I just don’t know if it would work.

    • Hi Marcia, I’m not quite sure if that would work based on the bake time for the biscuits and the potato casserole. But if you give it a try, let me know!

  32. I just made this today. It was delicious!! 
    I used redskin potatoes cut up really small, and included mushrooms with mine. I used pepper, seasoning salt, and onion powder for my seasonings, and I only used four eggs instead of six since I was cooking for one person. Absolutely delicious. I will definitely be making this again.

  35. I have no idea why my eggs didn’t cook through :( I followed he recipe exactly and when I went to scoop some into a bowl it was all liquidy!! Very upset cause I’ve been looking forward to this all week. wanted to have a “breakfast for dinner” night. Still love your blog! Wondering how I could fix it for next time.

  36. very yummy! We make this bacon for BFD! (Breakfast For Dinner) YUM! Thank you so so much!

  38. Can this recipe be made in advance and baked the next day?  If so how?

  39. This recipe was really easy and really yummy. My mother and sister loved it too. I love its versatility and its protein-punch; I am definitely someone who needs a hearty breakfast to start my day off right. It kept really well in the fridge and was great for leftovers for days too! THANK YOU! 

  40. Can you tell me how many people this recipe would feed? Would it feed 6 ppl or should I double the recipe,?

  42. Hi! If I prep this the night before and refrigerate, how much in advance do I need to let it thaw? Do you recommend same temps or changing the temperature. I love your recipes!! thanks !

  43. My son and I just made this casserole and I agree with the comment Joanna made. It did not turn out right. The liquidity of it was mostly in the middle however, some egg parts were done but it was around the edges. Not giving up though. I’ll try again probably next week.

    • I’m sorry to hear it didn’t work out for you guys Nicole! I’m not sure why it didn’t bake evenly for you, and why there was excess liquid. :( I appreciate you trying my recipe, and do hope you have better results next time!

  44. I’m thinking this should work well in a crock pot.  Do you have a recommendation as to how long I should put it on for?  I make breakfast for our son who has to be eating by 6:30 am.  I know to put it on low but for how many hours is a guess.  Thanks for your input.

  45. I was hosting a Norwex party brunch and this dish was super simple to make and everyone loved it! Recipe is going in the “keeper” pile! I did a double batch and it served 12 people and there was enough for plenty of leftovers.

  47. I made this the other day and it looked nothing like the photo. I was so disappointed. It looked more like a frittata. I might try it again because yours looks so good. Will use a wider pan and maybe less eggs. Yours is stunning looking!

  48. Just tried this recipe and in the moment of writting to you,  am still waiting for the casserole to finish cooking. I followed the directions waited for about 30mins for it to finish and like some of the commenst below, a lot of excess liquid from the eggs. But not a problem, I’ve been watching it every 10-15 mins and i think it just needed to cook LONGER. I can say it’s making um kitchen smell amazing, but no good for my husband who doesn’t like to wait. I substituted the sausage for ground Turkey and Turkey bacon and redbell pepper for tomatoes. I’ll have to try this out again and see what happens.

  49. I made this yesterday morning, when my friend came to visit, and it’s definitely a recipe I will be making again. I used 2 9oz packages of Jimmy Dean pre-cooked sausage crumbles, and the only frozen potatoes my supermarket had in the 20oz pack were the “O’ Brien” with onions and peppers already added in, so I skipped the saute portion of the instructions entirely.

    As we were loading it into the oven, my friend and I commented that it looked like a lot of casserole for my kinda small (11″ long) casserole dish, but we thought we’d give it a try anyway. The eggs turned out watery, like other commenters have said, so we stirred the casserole around thoroughly, halfed it into a second dish, and completely recooked it (for a whole second half hour, first w/ aluimum foil over it then without), and it turned out great! So for everyone w/ the watery egg problem, I would recommend either spreading the casserole across a second dish or scaling back the recipe. Thank you for the recipe, Ali! As I said I will definitely be making it again! Best wishes! — Caity

    • Thanks Caity, I’m happy to hear it was a hit! I’m sorry it was runny at first, but I’m glad it worked out in the end — thank you for sharing your tips! : )
