Wonderfully comforting Breakfast Casserole that will make any morning special. This Sausage Breakfast Casserole is made with fluffy biscuits, egg and milk mixture, sausage, and onions.
After many years of gathering our family for holiday dinners, we have to do something different this year. This year, my husband has to go to work on Christmas afternoon.
When I was done going through hundreds of angry emotions, I started to make piece with that fact. We decided to have our family over for a holiday brunch instead of dinner.
That’s different for me since I’m used to making dinner for everyone. Even though it’s different, I am extremely excited to serve something new to the family.
Brunch and breakfast brings so many possibilities. There are some sweet options like pancakes, waffles, muffins, and pastries. There are also some savory must-haves like bacon, sausage, eggs, and toast.
And of course, there are the best, comforting options like breakfast casseroles. Flavors for breakfast casseroles are endless. If our family enjoys this year’s brunch, I might just switch our Christmas celebration to mornings and try make more flavors in upcoming years.
This amazing breakfast casserole is awesome. It’s loaded with soft, fluffy biscuits, breakfast sausage and onions, and creamy egg mixture. It’s full of flavor but simple to prepare.
Can this breakfast casserole be made overnight?
Yes, it can absolutely be made ahead of time.
Prepare this casserole up to the baking step. Cover it up with saran wrap or foil and carefully place it in the refrigerator.
You can prepare it the night before and bake it in the morning.
Bake time shouldn’t be affected much, may be only by a couple of minutes.
Bake until it’s raised, golden brown on top and thermometer inserted in the center reads 165°.
Can cheese be added?
Absolutely! Go for it.
I recommend using shredded sharp cheddar cheese for this recipe. It will add extra flavors and go well with breakfast sausage.
Spread about 1 1/2 cups of shredded cheddar over the biscuits after adding sausage.
You can also add another 1/2 – 1 cup over the top of the casserole about 10 minutes before it’s done baking.
