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.

Substitutions:

  • Breakfast Meat: Ham, bacon, or turkey sausage would be perfect!

  • Veggies: mix in mushrooms, bell peppers, onions, broccoli or spinach.

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. Amy Long says:

    I covered it as it said for 45 minutes, but it barely cooked. Took the foil off and baked it for an hour, and then it was perfect. Very easy and delicious recipe and we ate off of it for a few mornings

    1. Shyanne - ATM Team says:

      We’re so glad you were able to make it work for you and enjoyed it, Amy! Thank you for the feedback.

    2. Jazmine says:

      It definitely needs to stay longer than the given time she stated.

  2. Alejandra Gauthier says:

    Hello! I made this recipe and it’s absolutely delicious and easy, I would say it took a little more than an hour for me (in total) because I used 3 potatoes instead of frozen hash browns, and it took a little more time to cook them for some reason, beside that I’m amazed, I also added I tsp of garlic powder and half medium onion, and it turned very good, my husband loved too! Thank you for this amazing recipe 💗

    1. Shyanne - ATM Team says:

      Thank you for trying it out and coming back to let us know how it went, Alejandra. We’re so glad you enjoyed it!

    Great recipe! No issues at all and the milk is not too much. My guess is people having issues don’t realize that just because your oven says it’s ready doesn’t mean it’s up to temperature! Best thing we ever did we get an oven thermometer. Most of the time ours will be “preheated” but only around 200-250 degrees and not 350. Definitely not a recipe issue for anyone who is concerned, just make sure your oven is REALLY up to temperature!

    1. Shyanne - ATM Team says:

      Thank you for the feedback, Rachel! We’re so glad it turned out well for you. 😊

    This recipe is actually really good. I do agree with everyone that the ratio of egg to milk seems wrong. At 45 minutes, it was still soup. But if you let it cook for another 30 minutes, checking often, it turns out wonderful. Maybe she has a much better oven than I do, I don’t know, but I will say it was worth the wait.

    1. Shyanne - ATM Team says:

      Thank you for the feedback, Heidi! We’re so glad you enjoyed it.

  5. Ali says:

    We loved this recipe, I used 1 extra egg a little less milk (using 2%), mixed half the cheese with the eggs, substituted bacon for sausage and cooked hash brown rounds in the air fryer before hand. I cooked for 30 minutes covered at 350 and took off the cover for 10 minutes. It turned out great. My kids loved it. Next time may add chives.

    1. Shyanne - ATM Team says:

      We’re so glad you enjoyed it, Ali!

  6. Whitley Owen says:

    Love how easy this recipe is! The first time I made it I felt like I needed to adjust the amount of milk because, hey, ovens vary. Second time I made it, I used 1.5 cups of milk and baked at 350 for 55 minutes (uncovered for last 15). Came out perfect!!

    1. Shyanne - ATM Team says:

      We’re so glad you were able to make it work for you, Whitley!

  7. Debbie Dorman says:

    I have always made it with 6 slices of bread torn into smaller pieces with the 2 cups of milk. Mix everything cover and refrigerate over night. Cook at 350 for 40 min. I have also uses smoky-links sliced to coin like size instead if sausage. Not soupy at all.

  8. cdahl says:

    Made this recipe for my first time.Only adjustment I made was using half of a 26 oz bag of hashbrowns, because that’s what I had. Turned out great! Will definitely make again.

    1. Shyanne - ATM Team says:

      We’re glad it turned out well for you!

    2. Rene says:

      No way this recipe is only 2g carbs. Matters not since I’m making it for someone else. When you count macros you learn an approximate range for ingredients. I wish it was only 2g per serving, I’d eat this up! 😀

      1. Shyanne - ATM Team says:

        Thanks for catching that! We adjusted the recipe card. 😊

  9. 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.

  10. Barbara says:

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

    1. Shyanne - ATM Team says:
