  • Prep Time: 15 minutes
  • Cook Time: 30 minutes
  • Total Time: 45 minutes
  • Yield: About 8 servings 1x


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


  • 1 pound ground Italian sausage (hot, mild or sweet)
  • 1 medium white onion, diced
  • 1 red bell pepper, cored and diced
  • 3 cloves garlic, minced
  • 1 (20 ounce) bag frozen diced hash brown potatoes*, thawed
  • 2 cups shredded sharp cheddar cheese, divided
  • 6 eggs
  • 1/3 cup milk
  • 1 teaspoon fine sea salt*
  • a few generous twists of freshly-cracked black pepper
  • toppings: thinly sliced green onions, sliced avocado and/or hot sauce


  1. Prepare oven. Heat oven to 375°F.
  2. Brown the sausage. Cook over medium-high heat in a large sauté pan until browned, crumbling the sausage with a spoon as it cooks. Transfer sausage with a slotted spoon to a large mixing bowl. Reserve 1 tablespoon of the remaining sausage grease in the sauté, and discard the rest.
  3. Sauté veggies. Add onion and bell pepper to the pan and sauté for 5 minutes, stirring occasionally, until softened. Add garlic and sauté for an additional 2 minutes, stirring frequently, until fragrant. Transfer the vegetable mixture into the mixing bowl with the sausage. Add the thawed diced potatoes and 1 1/2 cups cheese to the mixing bowl with the sausage and veggies. Toss gently until evenly combined.
  4. Add the eggs. In a separate small bowl, whisk together the eggs, milk, salt and black pepper until combined. Add the egg mixture to the potato mixture and toss gently to combine.
  5. Bake. Pour the mixture into a 9×13-inch* baking dish and top with the remaining 1/2 cup of shredded cheese. Cover with aluminum foil and bake for 40 minutes. Remove the aluminum foil and bake for an additional 10-15 minutes until the potatoes in the center are cooked through. Transfer the baking dish to a wire rack.
  6. Serve. Serve warm, garnished with your favorite toppings, and enjoy!


Potatoes: If you don’t have a bag of frozen diced hash brown potatoes, feel free to dice 20 ounces (nearly 2 pounds) of Yukon gold potatoes for this recipe.

Type of salt: I always cook and write my recipes with fine sea salt. But please note that if you are using iodized table salt, you only need to add about half as much.

Size of baking pan: This casserole will also fit in an 11 x 7-inch or 9 x 9-inch baking pan, if you prefer. It will likely just need an extra 5-10 minutes to cook.

  1. Breakfast for dinner? Count me in!

  2. Haha a “cook pleaser”–love it! My mom would definitely love this and I wish I could be closer to her to make it for her. We are 9 hours apart and it’s really hard!

  3. This casserole would be so good and not just for breakfast :D

  4. These photos are beautiful! My husband and I are house hunting right now and definitely want to stay close to my parents. I consider myself SO lucky that I can pop over and hang out whenever I want (and vise versa).

  5. I’ve read that women can’t resist two things 1.) chocolate and 2.) cheese. And I plan to have both for Mother’s Day!! For men, it’s peanut butter, right?!?

    I love how this can be prepared the night before and I can indulge on Mother’s Day but not have to cook that morning because as a mom with small kids, that’s a little lame.

    Your pics are smashing!! Thanks =)

  6. This is definitely my kind of breakfast and perfect for mom!

    I often have the same sentiments living three hours from my family. I would love to often pop in for a cup of coffee or grocery shop with my mom. It makes me really savor the time I do spend with her!

  7. This looks over the top scrumptious!! I’m in love

  8. Oh happy day. This looks SO good. Excuse me while I do as you instructed and dive right in :)

  9. I love this recipe. My honey and I try to have brunch with the family (or at least with each other) every weekend and this will be an excellent casserole to whip up and feed everyone with. Thank you!

  10. Does anyone know how many real potatoes I would need if I wanted to make the hash browns instead of buying frozen hash browns? And could I ues sweet potatoes instead of white potatoes for a variation?

    • I have another recipe that uses three pounds of potatoes cubed and boiled for eight minutes as a substitute for a bag of hash browns.

    • It depends on the size of your potatoes. I just made them with fresh potatoes, cubed, then microwaved the potatoes in a plate for 7 minutes. I followed the remaining steps as if I used thawed potatoes. Only different thing I did was not cover with foil because my potatoes were already precooked and baked it for 30 minutes. My family and I gobbled it up. Great recipe Ali! Thanks!

  11. Oh, this hits so close to home. My mom and I live 2 hours apart, and we only see each other once every couple of months. I know that is more than some people, but to me it is never enough time! And our weekends together always seem crazy hectic because we try to fit so much in. How I would love to live in the same city as my mom! Maybe one day. I think I’ll make this breakfast casserole for her on Sunday morning when I am visiting – thanks for the inspiration :)

  12. This looks absolutely amazing! Can’t wait to try it!

  13. This sounds awesome, Ali! I would love to try it with Field Roast vegan sausage for a veg-friendly version :)

  14. Perfect for Mother’s Day! So delicious!

  15. Yum! A breakfast casserole I would eat everyday if I could.

  16. Very loving and sweet blog about your Mom. I loved reading it.
    I know I repeat myself endless about this, but easy really is a key word for me. I know we all the same amount of hours in the day. But I am filling mine up these days, so that lingering times in the kitchen is a luxury. However I still like to eat well and have people over. Mmmmm. So recipes like this are much appreciated.

  17. Thank you for the Mother’s Day wishes!! So incredibly sweet. Sounds like you have a great momma and I’m sorry you can’t spend the day together. Thanks for this awesome casserole recipe. Pinned!

  18. If you make the casserole the night before, do you still bake it for the same amount of time?

  19. I really enjoyed you breakfast casserole and so did my guests, and it was easy to prepare. I plan to try it with chorizo next time. Thank you very much.

  20. I made this for Mother’s Day brunch today and it was a hit! Lots of compliments and it disappeared quickly :) It turned out perfect assembling it last night and baking it this morning. Thanks for another winner, Ali!

  21. Do you think you could use Egg Beaters for this?

  22. My guys would inhale this dish! I’d probably have to make two if I wanted to enjoy any of it! It would be great for a potluck brunch too

  23. How would this recipe turn out using breakfast sausage instead of italian? Have you done the recipe this way?

  24. This sounds delicious! Do you know how this is reheated? I wanted to try and do it at the beginning of the week and have it last a few days.

  25. We made this recipe for our “breakfast for dinner” tonight. I doubled the onions and red peppers, and used a sprinkling of salt while sautéing the vegetables, but otherwise followed the recipe as written. It came out beautiful, just like your gorgeous pictures, and was a huge hit. Thanks for wonderful recipe. I’m sure we will be making it often!

  26. Made this for a brunch and it was a hit! I used a bag of refrigerated shredded hashbrowns and it worked just fine. Great flavor and leftovers were great too. I could imagine making this on a weekend and eating it for several days for breakfast.

  27. Has anyone tried this with broken up pieces of bacon instead of the sausage? Curious how that would work. Looks absolutely delicious. Can’t wait to make it for the next family gathering.

    • I make something extremely similar with bacon but I cook it in a skillet instead of the oven. I cook the bacon first until crisp, pull it out and cook the potatoes in the bacon grease and season them. Also add any extras you want like green peppers, onions, or any other veggies you might like. Once they’re pretty cooked through, crumble the bacon over it, add scrambled eggs, and melt the cheese over it. It’s delicious!

  28. Now I know what to do with my breakfast sausage I’m thawing out!

    Any ideas for ground pork ?

  29. followed recipe exactly for portions but it seemed VERY thick for a casserole to cook through the middle so I split it into 2 casserole dishes and it came out super yummy. would definitely make this again, thanks!

  30. I am definitely going to give this a try and I will let you know, but this bunch loves things like this so it will no doubt be a hit. THANKS

  31. Can I make this with ground beef?

  32. Can you freeze the leftovers and if so, what is the best way to reheat them? The pictures look amazing, but I live alone and I couldn’t eat all of that if I ate it three meals a day!

    Thank you..

    • You can definitely freeze the leftovers. I would reheat them in the oven, if you want the potatoes to be crispy. But otherwise, the microwave works too. :)

  33. This looks delicious! You’d said you could make it the night before and bake in the morning–do you think you could make it two whole days in advance and have it still turn out ok, or would it get soggy sitting in the fridge for that long? I’m taking this along on a weekend trip and would love to have nothing to do except stick it in the oven on Sunday morning.

    • Gretchen,I was wondering the same thing! I’m thinking it will be fine but the cooking time covered in foil will just have to be longer. I’m also going to add rotel tomatoes and green chilies to mine. Good luck!

  34. Has anyone tried preparing this as a freezer meal?   Where did you STOP and freeze it or did you prepared the entire casserole and then freeze?  Did it work well?

  35. I had this recipe pop up on my ziplist, and after reading your comnent about your mom living in Wichita I was like OMG! How fun is this someone from Wichita with a food blog. Did you attend Wichita East High class of 87? Thelma 

  36. What size baking dish do you recommend? Is  a 9×13 dish about right?  Eager to make this for a brunch this weekend. Thank you!! :)

  37. 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!

  38. 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!

  39. do you know how many this serves? I Want ot make it in a 9 x 13 pan…should I double it?

  40. I’m making this recipe right now :)

  41. 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  

  42. 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. 

  43. 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! =)

  44. 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.

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

  46. 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! :)

  47. 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.

  48. I made this last weekend and it was wonderful.  Thanks for sharing!

  49. 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!
