Recipe Ingredients:

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. (They’re a key ingredient in my Hashbrown Casserole too!)
  • Milk – whole milk is best.

Substitutions:

  • 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.

How To Make Breakfast Casserole:

  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.

    Loved it. I added onion and bacon bits. I also cut small pieces of garlic bread and turned out pretty good!

  2. Pam says:

    4 stars
    Made this and it was very good. I will be making this again. I used turkey breakfast sausage and it had great flavor. Good recipe

  3. Pam Eckles says:

    It took much longer to cook than 45 mins covered w foil and 10-15 mins uncovered.

  4. Micah says:

    5 stars
    I’ve done this recipe multiple times for church breakfast potlucks and always get rave reviews. I use mild Italian ground sausage and diced hash browns. I also use lactose free milk and naturally lactose free shredded sharp cheddar cheese for a completely lactose-free casserole!

    I’ve also broiled it for the last 5 minutes to brown up the top, which makes a huge difference.

  5. Morgann says:

    This is a nice easy recipe. I do recommend cooking this dish at a higher temperature between 375°- 400° for the same duration of time. This will help avoid it being runny.

  6. Debbie says:

    I’m making this Christmas morning. Are hashbrowns right from freezer or are they thawed?

  7. Jennifer says:

    I’m making for Christmas. Has anyone tried thawing the hashbrowns before cooking? I’ve seen several people state that it was runny and wondered if that would help. Jennifer

  8. Trisha says:

    I have used this recipe several times. I use it as a “base” & adjust the ingredients to what I have on hand (bacon, spinach, peppers, onion, etc)

    1. Kerri says:

      5 stars
      Made this for Christmas morning breakfast and it was a big hit. I am remaking it again this weekend for company that’s coming. Thanks for the recipe. Nice and easy and delicious.

  9. Whitney says:

    5 stars
    I want to half the recipe— how long should the baking time be?

  10. Lisa Randall says:

    What size package of hashbrowns, also shredded or patty style?

  11. Lisa Randall says:

    What kind of hashbrowns? The ones that are in a patty or the shredded kind? And what size package? Help I want to make it for Christmas morning.

  12. Erica says:

    Trying this morning for church breakfast. Fingers crossed 🤞 Looks good before baking; so will see in an hour

  13. Whitney says:

    5 stars
    I’ve made this several times and my partner is obsessed. Love!!

  14. Sarah says:

    Is the recipe 1/2 of a 15 oz package of hashbrowns or it is 15 ounces total?

    1. Kasey Schwartz says:

      it’s 15 oz total.

  15. Mary Peterson-Riley says:

    Gonna make this on Christmas Day! Can’t wait! Easy and looks and sounds SO good! Thank you for sharing!

    1. Kasey Schwartz says:

      Be sure to let me know how it goes! 🙂

  16. Peggy Lambert says:

    Any suggestions on a side dish?
    Was slicing up some beef red tomatoes but not everyone likes tomatoes.

    1. Stephanie says:

      I top mine with mild chunky salsa and a side of crunchy bacon.
