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.

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.

    This recipe does not work. My casserole was soup.

    1. Agree is 2 cups of milk a typo? Ours was soupy also

  2. 1 star
    Been in oven for an hour and still jiggly in the middle.

  3. I don’t have any frozen potatoes. I have some russet potatoes. Will I get the same results?

  4. Looks great! Do you use diced or shredded hashbrowns? THANKS!

  5. Can this be frozen? It’s just me, my husband and my sister.

  6. Today was the first time I have ever made this recipe. It was a smashing success. I followed the recipe to the letter and it turn out perfect! I will be making this again! Cooked about an hour an 10 minutes.

  7. Made this for a birthday party brunch and it was great! Wondering if this would be something you can freeze and bake later? Thanks!

    I used soyrizo instead of sausage, added 1 can of rotel to the egg mix, reduced the milk and added 8 eggs instead of 6. This turned out DELICIOUS! Kids and adults loved it. Thanks for the idea!

  9. 5 stars
    Easy to follow and delicious!!!

  10. I would add a small can of diced green chilies (drained)

    I added one medium onion and a small green pepper to it. Cut back on the milk a bit, used 8 eggs verses 6. Made a 3 cup version of sausage gravy and used 1 1/2 cups in the casserole, saved the other half for biscuits I made up.

  12. Mike Meisinger says:

    I make this for my wife and she loves it! Says it reminds her of the breakfast casserole her mom used to make when she was growing up. She is so thankful I found this recipe, and so am I. I usually make mine a three meat: sausage, ham & bacon. Pure heaven!

    1. Kasey Schwartz says:

      That is great to hear!

  13. 5 stars
    I use maple breakfast sausage and use 8 to 10 eggs, because I use more eggs I add just a little bit more milk. I like the taste of the maple sausage and like to have more egg.

    I have been eating a casserole like this since a child for Christmas morning but now make it regularly for breakfast throughout the week. My mom would add onions and green peppers in hers but I don’t like those in mine.

    It does take about 75 to 90 minutes to bake normally but that could be because I add more egg, I could probably up the temp but don’t mind waiting.

  14. Your recipe call for 1/2 package Frozen Hashbrowns 15oz. Does that mean 1/2 of a 30 oz. bag or 1/2 of a 15oz. bag? Hope you see this because I plan to make them tonight for breakfast tomorrow morning.

  15. Does a double recipe still cook ok in a 9×13 pan?

    1. Kasey Schwartz says:

      NO it would not. I would make TWO dishes instead of trying to double this recipe in one pan.

  16. Making this for supper it’s in the oven right now hoping it turns out well

    1. MemyselfI says:

      Tripled recipe first time didn’t cook in the middle. Did recipe as is second time still didn’t cook in the middle. Delicious once we got it cooked.

  17. This is not a comment on a recipe, but I do have a question. I was not sure how to contact you. I am not on social media at all. Do you send out emails and updates on your recipes like you do on social media? I would love to start getting all your info/newsletters, if possible. Please let me know.

  18. I made a triple batch of the easy breakfast casserole for a church breakfast. It was simple, easy, and delicious. There wasn’t any left to bring home!

  19. I got a little nervous after I put this in the oven and started reading comments. I fully expected a soupy mess but it was quite the contrary, I used bacon instead of sausage and followed the recipe exactly. I did add a few seasonings garlic and onion powder salt and pepper. I have a gas oven and baked it accordingly. My family cleaned their plates and throughly enjoyed brunch today. Thanks for the recipe

  20. Can this casserole be made in muffin pan?
