You just need to keep a few simple ingredients on hand to whip this baby up anytime you need a dose of comfort! It’s also the perfect breakfast to whip up on Sunday and enjoy during the week with just a little microwave action.

NOTE: Updated baking times.

Ingredients needed for this recipe:

For the entire recipe ingredients, see the recipe card below.

  • Sausage – I like spicy breakfast sausage for this recipe, but mild is good if you have littles in your house.
  • Eggs – whisked together
  • Shredded Cheese – I like cheddar but you can use your favorite
  • Frozen Hashbrowns – you can use hashbrown potatoes or shredded.
  • Milk – whole milk is best.


  • Breakfast Meat: Ham, bacon, or turkey sausage would be perfect!
  • Potatoes: tater tots or shredded hashbrowns would be fine to use.
  • Cheese: Colby Jack, Pepper Jack, Swiss cheese, or Monterey Jack are good substitutions for the casserole.
  • Milk: Mix it up! Add half and half or heavy cream in place of 1 cup of milk.
  • Veggies: mix in mushrooms, bell peppers, onions, broccoli or spinach.


  1. Prepare: Preheat the oven to 350 degrees.
  2. Brown the Sausage: Crumble sausage into a skillet on the stove and brown completely. Remove from heat.
  3. Whisk the Eggs: In a large bowl, mix eggs and milk together and whisk well.
  4. Add seasonings: Add salt and pepper to the egg mixture and stir.
  5. Mix ingredients all together: To a 9×13 dish sprayed with cooking spray, add frozen hashbrowns, sausage, and cheese.
  6. Add to the baking dish: Pour the egg/milk mixture into the dish.
  7. Bake: Bake at 350 degrees for 45 minutes – covered with foil.
  8. Rest: Remove the foil and bake for about 10-15 minutes more until the dish is bubbly and cheese is melted.

What to Serve with a Delicious Breakfast Casserole

Make this a complete meal is easy by adding a few breakfast favorites to your menu. This breakfast casserole is perfect alone but if you are looking for some side ideas, I’ve got you covered! Here are some ideas of what can go along with this breakfast casserole recipe during the holiday season.

Breakfast Casserole Tips For Success

Make ahead: You can easily make this casserole the night before and bake in the morning. Just cover in the fridge and take out while your oven is preheating. You may need to increase the baking time by 10-15 minutes.

Baking Tip: This casserole is done when the edges are set and lightly brown and the center only jiggles slightly. Make sure there is no “watery” eggs in the center before removing from the oven.

Storage: Cover the entire casserole with foil or a lid to your baking dish and refrigerate for up to 3 days.

Reheat: Reheat in the microwave.

Freeze: This casserole can be frozen. First bake your breakfast casserole and once it has completely cooled, place in an airtight container or ziplock bag. When ready to warm up, place in oven and bake at 350 degrees until warmed through about 20 to 25 minutes.

  1. Savannah Rogers says:

    everything looked great until we cut into it, then it was sitting in a puddle of water. What gives?

    1. Shyanne - ATM Team says:

      Sorry to hear this, Savannah! Sounds like it just needed a little longer in the oven.

  2. 5 stars
    Easy and delicious recipe. Thanks for sharing it!

    1. Shyanne - ATM Team says:

      Thank you, Barbara!

  3. Stephanie D says:

    I usually make this same thing in the crockpot overnight for Christmas morning. Who wants to cook breakfast on Christmas morning? Not me. The only exceptions are: one 30 oz bag of frozen shredded hashbrowns, 1 lb cooked and drained sausage, 4 cups shredded cheese, 12 eggs, 1 cup of milk, and your seasonings. Mix hashbrowns, cheese, and sausage together, pour egg mixture over top, cook on low in crockpot for 8 hours. And Christmas breakfast is served. I came here because I’m basically making the same thing after work for a week night dinner and I needed oven temps and time. 2 cups of milk sounded like alot to me, but I did it and we’ll see!!

    1. Shyanne - ATM Team says:

      Thank you for trying out our recipe! We’d love to know how it turns out!

  4. Will it work if the hashbrowns aren’t frozen?

    1. Shyanne - ATM Team says:

      Hi Kelly,
      It should work with thawed hash browns. Just be sure to keep a close eye on the oven, and adjust the baking time as needed!

  5. Can you use bacon instead? I have family members that are pretty fussy

  6. 5 stars
    My wife and I loved it. We cut back on the sausage and added spinach, great recipe!

  7. Samantha McCrary says:

    Followed the recipe exactly no problem thought the ingredients might be a big amount like 6 eggs and 2 cups milk, but everything worked perfect. I work on the weekends, and I was told it was great. It was gone in 20 I never got to try it. Making it now for the fourth time for work and they never get tired of it and it’s so simple.

  8. Preppingmom says:

    Can you add can biscuits at the bottom ?
    Can it be frozen?
    Thank you

    1. Cindy Spring says:

      I made this without meat, looking kinda liquid in center 👍🏻 hoping it cooks through

  9. Two thumbs up!! I am not great at cooking, so when my husband told me, “Definitely make this again!”, I was so excited! Finally, had made a dish that I felt confident with. Yay! I have also made this recipe on our annual family beach trips, too, with 20+ people, and it’s a hit! So easy to double and triple this recipe. Tip: shred the cheese yourself instead of buying preshredded..it just tastes better for some reason.

  10. Lynne Daly says:

    5 stars
    Definitely will use this recipe again when family comes into town! I followed the recipe exactly and it turned out great!

  11. Dahlia Queen says:

    But can you put it together the night before so you can just heat and eat in the morning? Serves about how many??

  12. I love this go to-prepare ahead- breakfast for all occasions! I’ve been using it and modifying it for the last couple of years and it is always a hit. I always use spicy sausage or hot Jimmy Dean, pre-cook my hashbrowns, and dice up sautéed onion. I prefer to cook it the day before minus about 10 minutes and pop it in the oven for about 20 before I serve it the next day with hot biscuits and sides of avocado.

  13. Osiyo Bear says:

    1 star
    Listen to everyone! 2 cups milk is way too much and the temp could be higher from the start to bake this more efficiently. I added extra eggs but it still was a soup after 45 min so I had to up the temp and cross my fingers I wouldn’t have to pull out some of the liquid. Not a great recipe at all!
