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.

  1. 5 stars
    This is the easiest and cheesiest breakfast casserole. I love breakfast dishes anytime of day. Breakfast, lunch, dinner or leftovers as a snack! This casserole is a keeper!

  2. I liked this recipe a lot ! I found that it needed a lot more time in the over than indicated, when I removed the tinfoil the first time it was basically liquid still, and I had to cook it about 30 minutes without the foil ! So next time I may increase to 375 and see what happens : I used sweet potato tots for my hashbrowns and that was yummy !

  3. This recipe is great. I think that because there are less eggs than other breakfast casseroles makes it work so well. I added onions, bell peppers, and mushroom with my breakfast.

  4. 5 stars
    Easy and absolutely delicious!

  5. Could this recipe be halved for a 8×8 baking dish?

    1. Kasey Schwartz says:

      Sure! I do this all the time!

      1. Could you mix this together and cook the next morning

    2. It freezes well. It’s a great thing to make on Sunday and then cut into portions for the week.

  6. 5 stars
    wonderful!! easy to make!!

  7. 5 stars
    Made this breakfast casserole, we loved it! It’s simple to make and delicious.

  8. 5 stars
    I have made this recipe so many times. Making it right now for my Sunday School class. I generally always add chopped onions and chopped green chilis to give it a little kick. Good recipe!

    Thoroughly enjoyed this casserole – very quick and easy, and totally yummy. I did toast the hash browns before cooking, but I don’t know if it made a difference or not. Thanks!!

  10. 5 stars
    I made this today. Super easy baked up perfectly. I think this is a recipe that is very versatile, add peppers or onions, I added bacon bits because I had some to use up. Delicious.

    1. Can the Simply potatoes that are not frozen work too?

      1. 5 stars
        I have made this several times for Sunday Brunch and everyone has enjoyed the simplicity of the casserole. Many of the guests were glad there was no peppers and onions added. (1 change, I use dehydrated hashbrown potatoes)

      2. When you used the dehydrated kind, did you rehydrate them first? Or throw them in still dried? And how did it turn out when you are it? Did you change anything else? Thank you!

    I made this the night before for a Christmas breakfast for several people. It was easy to make and baked up very nice. It was a little dry but otherwise everyone loved it and asked for the recipe. Next time maybe will add a little more milk. Thank you for a very easy go to breakfast casserole.

    Made it exactly as written. It was way too soupy in the middle. Over an hour and half later it was still soupy. Probably way too much milk in this recipe or hashbrowns need to be thawed before hand. Not the greatest recipe.

  13. The 15oz for the hashbrowns….do I use half of a 15oz bag? Or am I using half of a 30 oz bag of hashbrowns? How much (in oz) go into the recipe??

    1. Kasey Schwartz says:

      Half of the bag.

      1. Jamie Shepard says:

        Half of what size bag!???!

      2. Michelle - ATM Team says:

        Hey Jamie! The recipe calls for 15 oz. The bag is 30 oz. Hope this helps!

      3. I thought the same thing, so I used enough to put in the bottom of the dish. Seems 1/2 of 30 oz bag was good.

  14. 5 stars
    First timer! Perfect timing in my 9 3/4″ square dish using 1 less egg & 1/3c less milk. I added sauteed onion just cause I like it!

  15. How many does this serve?

    1. Kasey Schwartz says:

      12 squares – but sometimes we eat more than 1! 🙂

    My family enjoyed this breakfast dish very much. They said it was a keeper.

    1. Michelle - ATM Team says:

      Yay! It’s definitely a family approved recipe!

    2. I decreased the milk by one and increased the eggs by two. It was perfect!

      1. Debra Heselton says:

        I have a similar recipe but it calls for crescent rolls. I line the bottom of my pan with the rolls and add the other ingredients. After it comes out of the oven and I serve it, I make gravy to top it with. Yum yum!

  17. 5 stars
    Absolutely wonderful!!! I didn’t change anything, only added onions and yellow and red peppers. This was so good that my hubby is asking for it again this weekend.

  18. 3 stars
    It’s good but definitely takes longer than it says. I’m not sure if it needs less milk or just leaving the cover off the whole time would work better. I left it on for 45min like it said, but then after taking it off for 15min, it was still very runny. Ended up taking an hour and a half and I had to turn up the heat which was frustrating because I was on a time crunch. I suggest a test run. I will say I made the mixture the night before and stuck it in the fridge to throw in the oven the next morning, so it could also have taken longer because it came from cooler conditions. In the end it tasted good tho!

    1. Kasey Schwartz says:

      Lynn, that’s exactly why it took longer. The recipe instructions are for ingredients that haven’t been chilled for 8 hours. We do have an Overnight Breakfast Casserole that is similar you could try. I bet it was frustrating when you changed up the instructions and it didn’t work for you!

      1. Garland Charles Barmore says:

        Then I’m screwed. It does say some where on this very needy page that you can refrigerate and cook the next day. No updates on cooking time with that note though. That woof be helpful.

    Good for First casseroles. It Was Delicious. Added greeb bell pepper for good flavor
