How to Make An Easy Breakfast Casserole – QUICKLY!

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.

    I make one on Sunday and divide it into portions to go in refrig. I just warm one each morning. I also add some bacon bits with the sausage.

  2. 5 stars
    So good! We used Southwest hash browns with bell peppers and onions. So much flavor.

    EXCELLENT!!!! Easy to make.

    This is a good recipe but it calls for way too much milk. I didn’t think two cups sounded right but I went with it anyways. When my casserole was now is looked good on top but when I cut into it it was all soup. So I spooned out the extra juices and put it back in for another 30 min. Hopefully the eggs will cook without burning everything else. Next time I will try one cup.

  5. 4 stars
    I made two of these casseroles. I used frozen diced potatoes and put them in the refrig the night before. In the 1st casserole, I sauteed cut-up pork sausage links and diced onions and it cooked in the time suggested and was very good.
    The 2nd casserole had diced ham that I first warmed in the microwave and drained the excess liquid. This ham version took about 25 minutes more time to cook and I increased the temp to 360 degrees once I took the other casserole out of the oven. Next time I will add more seasoning since the potatoes didn’t really absorb any flavors.

  6. I am confused. It says look for updated cool time. I scrolled to 2020 comments and don’t see a revision. Soooo not sure what to do?

  7. 5 stars
    Even with the updated cooking times I still had to cook for over 1 ½ hours. However, we were patient and waited for it to cook properly and it was delicious.

    1. Kasey Schwartz says:

      Did you start with a cold dish? Frozen ingredients? Lower temp? All ovens are different so times could change.

    2. Hi! Looks good, tastes good, but needed nearly double the cook time and I upped the temp to 450.

  8. 5 stars
    Just what I was looking for! This recipe is so fast to assemble and easy to follow.. not to mention simply delicious. The baking times in a gas oven worked perfectly for us. Thanks for helping me make something easy for my dad to wake up to at 5 am!

  9. Haven’t tasted it yet but the recipe should be updated with at least cooking in the oven at 400-425° for an hour or so . Very disappointing, I would have set aside more time for this.

  10. 5 stars
    Great! I made this without any potatoes (dad can’t eat them. I used 10 eggs, and a mixture of milk and half & half, plus I added some finely diced mushrooms. After reading the comments on cook time, I increased the oven temp to 400 degrees and cooked for 45 mins. It was perfect! It was juicy and not dry (I think this can happen with too many potatoes). Dad and hubby love it! Thanks!! Will definitely make again!

    I made this for Easter breakfast and boy was it a hit! Everyone wanted the recipe. I will be making this regularly, not for just special occasions.

  14. Wendy Underwood says:

    Very good, but mine took nearly two hours to fully cook

    1. 3 stars
      Haven’t tasted it yet cuz it’s been in the oven 90minutes. Looks good but won’t make again.

    Very easy to make and conveniently fast. My family loved it. Will make it again. Thank you for the recipe

  16. This casserole is easy and delicious! I made it for Easter brunch and it was a hit. Next time ( and trust me, there will be a next time) I will try the spicy sausage because my family loves a little heat. A must try!

  17. 1 star
    Based on the comments I thought this would be good, but it has no flavor. Add a block of cream cheese and actually cook the hash brown first and add some garlic powder and you’ll have a good casserole.

  18. 5 stars
    It was delicious and I will definitely be making it again!

  19. 5 stars
    I made it this morning, I did however chopped up my peppers and potatoes last night and put them in a freezer lock bag till this morning. I added this to my sausage after almost done cooking, just until all was a bit soft. I mixed all that with the cheese and followed the recipe from there. Oh, I did 7 eggs, as that’s what I had left in a cartoon. I also used a bit more cheese and a tiny pinch of Thyme. Severing with fresh strawberries and blackberries. It smells delish! I’ll be back to update how it came out. Thank you so much for the recipe. So easy.

    1. 5 stars
