Creating This Sausage Breakfast Casserole Recipe

I’ve had plenty of savory breakfast casseroles, but I’ve rarely had one that I can’t wait to get the recipe for. It seems like it’s often bland or way too eggy.

We have an absolutely delicious recipe for a Southern Breakfast Sausage Cake with, wait for it, a maple butter sauce that has changed me on savory breakfasts forever. It is slam packed full of flavor and something I’m not craving. It’s exclusive to our new cookbook, Our Sweet Basil Kitchen!! It’s on sale for the holidays, so hurry and snag a copy before prices move back up!

Anyway, that recipe set us out to discover more savory breakfasts that would be worth making, and after a little event at our church we both decided to make a good hash brown casserole.

Sausage Breakfast Casserole Ingredients

This sausage hashbrown breakfast casserole starts off with good sausage. This is the most important part as the sausage will breath flavor into the entire dish. We like to use a medium or maple sage sausage, but of course, use whatever you like. You could throw in diced green chiles and peppers too, but we will leave that for another time.

The hash browns are totally frozen, but if you feel ambitious go ahead and shred your own. Now, we do cook them a little but that’s because we noticed that not crisping the potatoes or adding them to the hash brown egg casserole while still frozen led to a soggier casserole.

In addition to these two key ingredients, we also added: 

  • Diced onion
  • Milk
  • Shredded cheese
  • Eggs 

We wanted to keep things simple without compromising on the flavor, and we did just that!

How to Make Sausage Breakfast Casserole

This egg bake with hash browns couldn’t be simpler to make. Here are the basic steps for making this easy breakfast casserole: 

  1. Whisk together the eggs, salt, pepper, and milk. 
  2. Brown the sausage in a skillet, then cook the onion alongside the meat. 
  3. Remove the sausage and onion from the skillet, then add in the hash browns (you want them to crisp up a bit). 
  4. Place the hash browns in the bottom of a greased 8×8-inch baking dish. 
  5. Top with the sausage mixture and half of the shredded cheese. 
  6. Pour egg mixture over that, then top with the rest of the cheese. 
  7. Bake until set and golden brown.

Can You Freeze Sausage Breakfast Casserole?

Yes, you can freeze this easy hash brown casserole either before you bake it or after it has come out of the oven and cooled. A properly frozen sausage breakfast casserole will keep for up to three months.

Can Breakfast Casserole be Made the Night Before?

Yes, you can prep this sausage breakfast casserole the night before, making it the ultimate lazy morning meal. Prep it, wrap it tightly in plastic wrap, and refrigerate it overnight and then pop it into the oven. Unbaked hash brown breakfast casserole will keep for a few days if covered well in the fridge, but the potatoes do break down a little more each day so just be mindful of that.

Can I Double This Recipe? 

Very easily, yes. You’d need to bake this sausage hash brown casserole in a 9×13-inch baking dish, and the cook time may need to be adjusted slightly. You’ll know it’s done baking when it’s set and golden on top!

Tips for Making Sausage Breakfast Casserole

For this sausage egg hash brown casserole, we used a blend of mozzarella and sharp cheddar cheese. We picked mozzarella for the gooey factor and sharp cheddar for the flavor. However, you could use pepper jack, colby jack, or any other combination of cheeses you like. This is a versatile sausage breakfast casserole recipe, so have fun with it! 

A few readers have asked about adding extra veggies (like chopped bell peppers) to the sausage mixture. We think that’s a great idea! Just cook the veggies alongside the onions and sausage — no need to change the recipe more than that. 

And lastly, if you’re shredding fresh potatoes to make your own hash browns, note that you will still need to cook the potatoes in the skillet first before transferring them to the baking dish. You want those hash browns to be nice and crispy, otherwise they’ll turn to mush in this sausage breakfast casserole.

  • Could you cook this in a 9×13 pan instead?

    • I would double the recipe for a 9×13 pan. It will be super thin if you don’t double it.

  • It is Christmas morning and I am really confused about how much cheese to add to my breakfast casserole. It would so much more helpful if you would include weights as well as volume. It is so much easier to weigh than guess how packed the cup should be. Plus, I seem to be getting different information depending on the source. One website says 2 ounces = a cup, while at another, a recipe calls for 1 1/2 Cups of cheddar or about 6 ounces of cheese! That would indicate 4 oz = 1 Cup!! That is double! I know its cheese, and you can guesstimate your preferences, but I would prefer to have a starting point. That said, I am looking forward to trying this sometime today!

    • I’m sorry this is going to be too late, but you can really do however much cheese you want. I just made this about a week ago and doubled what it says in the recipe and it was delicious. For hard cheeses like the ones used in this recipe, 1 cup = 4 ounces.

  • The Cheesy Sausage Hashbrown Casserole is the bomb dot com!!! Very easy to make with few ingredients. The Maple sausage gave the dish a slightly sweet hue with the savory flavors. Will be making this very delicious dish again, but will experiment with Sage Sausage. Thank you so much for sharing.

    • Sage sausage will be delicious too! Thank you for the feedback and I’m so glad it was a hit!

  • All of that fits in an 8×8? Just confirming. Can’t wait to make it!!

  • The recipe turned out well as written. It was cooked through and seasoned perfectly. But, the egg to potato ratio was way off. I guess that’s just a personal preference. My guests liked it, but I would definitely tweak it if I was making a small batch for myself as a make-it-ahead breakfast.

    • Would you say it needed more egg or more potato?

  • Hi,
    If we use fresh potatoes do we need to precook those too so they aren’t soggy? Or just the frozen ones? If we use frozen ones how long do we cook them? Until they are crispy and cooked through or? Thanks!

    • Reply
    • You can use either fresh or frozen. Frozen is just so much less work that that’s what I usually go with. I’m lazy like that! Haha! Both need to be cooked in the pan until lightly golden brown.

  • Can I use frozen O’Brien potatoes instead of shredded hash browns? Would I need to change anything? I want to make this the night ahead.

    • Reply
    • Yes absolutely! Just be sure to cook them a little first just like it says in the instructions so it doesn’t turn out soggy! No changes needed! Enjoy!

  • Hello! I am making a thank you brunch in a couple of days. I’ve been researching breakfast casseroles, and am really impressed with yours. I’d like to add some red and yellow bell pepper to this recipe . . . do you think I need to make any adjustments to your recipe to successfully incorporate the peppers? Thank you for your time!

    • Reply
    • Hi Sharmie! No, I don’t think you will need to make any adjustments. Just add the peppers to the casserole before baking! Enjoy!

      • Thanks!

  • Hi!

    I would like to serve this for a brunch the day after my son’s wedding – but I can’t make it that morning or the day of the wedding. If I make it ahead and freeze it, do you recommend cooking it completely and then just freezing it and warming it up the morning of the bunch? If so, thoughts on how long and what temp?


    • Reply
    • Hi Kathleen! Great questions! Yes, cook it completely and then let it cool completely before freezing. Do not put the cheese on the top though. When taking it out of the freezer to cook it, we cook it covered at 350 degrees F until the middle is not cold (about 30 min), then we uncover it, throw the cheese on top and cook it for another 15 min or so until the cheese is melted and crispy brown.
