Hashbrown Breakfast Casserole has it all.It’s loaded with all the good stuff and it’s perfect for feeding a crowd, not only because everyone loves it, but you can do all the prep work the night before and just pop it in the oven the next morning. It’s my go-to for any holiday morning or when entertaining guests.
I adapted this recipe from my popular classic Breakfast Casserole recipe, which is similar, but doesn’t use hashbrowns). We like to serve it with buttermilk biscuits, fresh fruit, or orange julius.

Combine: Mix eggs, sour cream, milk, cheese, salt, and pepper in a large bowl. Stir in thawed hashbrowns. Cook sausage in a large skillet, breaking up with a meat chopper or wooden spoon as it cooks. Drain most of the grease then pour into the egg mixture. Cook chopped veggies in the same skillet the sausage was cooked in for 2-3 minutes then pour into the bowl with the egg mixture.
Bake: Grease a 9×13″ pan with cooking spray then pour in the egg and sausage mixture. Cover and refrigerate overnight, or bake immediately for 40-50 minutes at 350°F. The edges of the hash brown breakfast casserole should be set and the center just barely jiggly.

We loved this casserole. I was looking for something different for dinner, and this was the perfect meal. I made it again, and didn’t have the right sausage, so I used lamb bratwurst. It was good that way too. We are adding it to the monthly meal rotation list.
Love this recipe! Was so easy to put together the night before a softball tournament where we would be gone most of the day and knew we wouldn’t get a filling meal the whole day. Just threw it in the morning and everyone had full tummies for a while!
Just made this for the week I was going to be having surgery and it worked out perfectly. Tasted amazing the first day, but warms up great and the family had the perfect before school breakfast while I was recovering. Definitley will be making this one again.
Delicious! So hearty and tasty and very easy to make. I had some chorizo on hand and used that in place of the sausage and it worked perfectly! The leftovers reheat beautifully as well, so it made for a few nice and easy mornings.
Delicious as always!! My favorite recipes always come from TBFS!!
Reasons I love this recipe: easy prep and can make the night before! Love the alternatives you suggest for easy swapping. I like to use the spicy jimmy dean sausage too!
I had a tried and true hash brown egg casserole recipe so I wasn’t going to try it but I’ve never made a Tastes Better From Scratch recipe my family didn’t love so I thought why not? This is now our new hash brown casserole recipe! It was so good! The sour cream adds this extra creaminess and it’s the perfect balance of meat, eggs, and potatoes. I was unable to get frozen hash browns so I subbed 2 1/2 cups of fresh grated potatoes I soaked in cold water. They worked perfect! Can’t wait to make this again!
I made this Saturday morning and it is a keeper. Next time I might put some sausage gravy on it.
Love your recipes! Would like to see more air fryer ideas …..
Love, love, love this! I made this for a family brunch and it was literally devoured in minutes. I also loved how easy it was to put together.
