Sausage Breakfast Casserole
This post may contain affiliate links. Please read our disclosure policy.
I love making this Sausage Breakfast Casserole when I need an easy breakfast that can feed a crowd. It’s layered with savory sausage, eggs, bread, and plenty of cheese, then baked until golden and fluffy. Whether I’m making breakfast for the holidays, brunch with friends, or just a weekend family breakfast, this sausage and egg bake is always a hit.


Key Ingredients
- Sausage – I grill the sausage links, cut them up and mixed them in. Cooked ground pork sausage is also a great mix in.
- Hash browns – Be sure to thaw these in the fridge overnight before preparing the casserole so you don’t end up with a soggy casserole.
- Marble jack cheese – I buy a block and shred it myself for the ultimate melty cheese and best flavor. Cheddar cheese, mozzarella or even pepper jack are some other tasty cheeses.
- Whole milk – A higher fat percentage will give you the creamiest casserole.

How to Bake In The Oven
Pepare breakfast casserole according to directions. Bake in oven preheated to 350 degrees Fahrenheit for about 60 minutes or until middle is set.
Serving Suggestions
This is a full meal on it’s own, but if I am feeding a big brunch crowd, I’ll add some Blueberry French Toast to the grill. Egg Muffins and Cinnamon Rolls are also really good additions to keep that crowd happy.
Pro Tips
- Prepare this casserole up to 24 hours in advance and allow the dish to come to room temperature for about 30 minutes before grilling or baking.
- Go meatless by leaving out the sausage and filling up the casserole with diced vegetables such as green onion, mushrooms, spinach and bell peppers. Any veggies will be great but try to sauté them beforehand so they don’t make your casserole soggy.

How would this work if I added vegetables like – bell peppers?

That would work fine, layer them in with the sausage over the hash browns. Hope you enjoy it!
Rachel says
Do you use frozen hash browns or do you have to cook them first?
Megan Mitzel says
This recipe calls for thawed hash browns so you can either thaw out or slightly cook some frozen hash browns or use a refrigerated variety.
Caitlin says
Could you make the night before and leave in the refrigerator? Also, anyone ever double it to feed more people… do you think it would have to cook a lot longer?
Julie Evink says
Yes you could do that. I would just simply make two pans if you are doubling and cook time would be the same.
Mary Kitchin says
I’ve been making this casserole for years using different variations of foods…One really good tip for any way you make it is to mix a can of Cream of Mushroom soup with a half cup of milk together and spread it on top of the casserole before you put it in the oven! Absolutely delicious!
Julie Evink says
Great tip! I’ll have to try it this way next time!
