I love breakfast foods so much and this Breakfast Casserole is very high on my list of favorites. I love our easy breakfast casserole recipe for so many reasons – it takes almost no time to put together, it can feed a crowd (hello Christmas morning breakfast idea!), it can easily be scaled up or down (or just make the recipe as is and have leftovers, which are delicious) and the flavor is incredible! It’s a great make ahead dish and delightfully indulgent.
As far as breakfast casserole recipes go, we love how easy this one is to throw together. It uses frozen hash browns with sausage and egg for a perfect savory quick and easy breakfast!
Although this is a breakfast casserole, it makes a lovely brunch dish or even a nice and hearty breakfast for dinner meal! It’s also very versatile and can be made with a variety of other ingredients like bacon instead of breakfast sausage and other veggies like mushrooms and spinach can be added in too!

Tips and Tricks for Breakfast Casserole Success
While this breakfast casserole recipe is a simple one, there are still a couple things that can come up and a couple things I can recommend to make this the best experience possible!
Common Issues and How to Solve Them
- Runny Casserole – Baked egg dishes often fall victim to excess liquid build up after they’re baked. The reason is due to high water content in some vegetables and dense meats that are used in these dishes. Browning /cooking the meats (and draining off any excess liquid) and sautéing the vegetables before cooking often helps this issue. The potatoes should be completely thawed, with any excess liquid drained, then pat dry.
- Shredded Cheese Stuck to Foil – It’s best to avoid your shredded cheese topper from touching the bottom of your foil when baking. If your shredded cheese topper is flush or heaping above the edges of your baking dish, spray the bottom of the piece of foil you’re going to use with cooking spray. This will help to prevent your cheese from sticking to the foil.
Breakfast Casserole Recipe Tips
- Shred Cheese Yourself – Although it can be tempting to buy a bag of pre-shredded cheese (at times I’m totally guilty of it too!), I highly recommend shredded your own cheese. It only takes a minute or two and the results are way better! Pre-shredded cheese tends to have anti-caking agents mixed into the bag, to prevent the shreds from clumping up, but it also prevents the cheese from melting smoothly and evenly.
- How to Tell if Breakfast Casserole is Done Baking – If you’re unsure whether or not your eggs have fully set, take a butter knife and insert it into the center of the casserole. Push the knife slightly to the side, if you see some pooling occurring you need some more time, if not you’re good to go!
Variations for Our Breakfast Casserole Recipe
- Steamed or sautéed spinach make a great addition to this breakfast casserole recipe. Just be sure to squeeze out as much water as possible before incorporating it into the dish.
- Sausage can be omitted and replaced with more bell pepper and onions to make this (an egg friendly) vegetarian version.
- Load it up with more veggies with some chopped broccoli, sautéed mushrooms and sautéed zucchini.
- Diced ham or crumbled bacon also make great protein options.
- Stir in a (15 ounce) can of well drained diced tomatoes, some well drained canned black beans, a pinch ground cumin and coriander, chopped cilantro, and top it with crumbled queso fresco and serve with a dollop of sour cream on the side for a little more of a Mexican inspired vibe.

To clarify – to make ahead, you “tightly wrap pre-baked casserole with foil and store in the refrigerator”… so we fully bake it, and then bake again from the fridge for 45 + 5 min total? Or do you mean “pre-assembled casserole”?
The casserole should not be baked twice. It’s stored in the refrigerator covered and unbaked. Then when you’re ready to bake it, just add 5 minutes to the original 45 minute bake time
Thank you so much for the quick reply! :) Can’t wait to make this the family over Christmas break. Wishing you a cozy holiday and new year!! xo
This looks like a recipe my husband would love. Can’t wait to try it out!
Been baking this for over 30 years. One trick my grandma taught me with breakfast casserole is to use a Bain Marie (water bath) when baking. Keeps the bottom and edges from over browning and allows more uniformity in cooking the entire dish.
oh, that’s a great idea! Thanks for the tip!
Hi, I’d like to make this to warm up for breakfast throughout the week. How long would it stay good for?
It stays fresh for 3 to 4 days
My family loves this casserole and they know if I’m not working on a Saturday this will be their yummy breakfast. I use chorizo instead of sausage. I also switch up and use shredded potatoes, hash browns or tater tots and whatever cheese I have. It’s delicious and filling every time. Thanks for sharing your recipe, it’s a quick one dish, delish, and easy clean up.
I’m so happy you and your family enjoy this casserole! Your swap-ins sound great!
Hi, I love your recipes and am looking forward to making this one! Question… can I premake the casserole on a Thursday night and have it sit in the fridge until Saturday morning? Or should I do it fresh?
Hi! Thursday night to Saturday morning should be just fine!
This looks so delicious! Do you think I could assemble it and freeze it before baking?
I’ve made this recipe several times now and given that my family loves spicy, I added a jalapeño to the onion mixture and it is so good!
Great recipe
Great casserole. Served it this morning and the pan was scraped clean! Great addition to our Xmas morning menu. Thanks for the recipe.
I really liked the recipes! I will try them out as soon as I can! Thanks! Bless you! Stay safe!💪💆♂️💜💆♀️💓🙏🏿🗣⚕🖖✌😊✡🎶🎄Merry Christmas!
Can’t wait to make this! Can I use fresh potatoes? My grocery store was all out of frozen potatoes!
Hi! You can use fresh potatoes, but a little more work will be needed (in addition to dicing the fresh potatoes). The frozen ones tend to be flash fried then frozen, so it works in our recipe that everything bakes up evenly. If you don’t want to shallow fry a bunch of potatoes, you can toss them in some oil, spread them on a sheet pan and roast them at 400F for 12-18 minutes until they’re partially roasted. Then cool them completely before using them in the recipe as instructed. Hope that helps!
Thank you!! Will try it that way!
I’m going to surprise my boyfriend this casserole for Christmas morning. Sounds delicious
This was FANTASTIC!
I gave this casserole a test run yesterday, for Christmas morning and DANG it’s a tasty number! I can’t wait to make it for my family (and with minimal effort!)!
