It’s basically the same recipe, but with sausage. You can make this sausage breakfast casserole overnight. It’s perfect for holiday breakfasts because you can prep it the night before, stick it in the refrigerator, and then just bake it in the morning. It’s also a great brunch breakfast casserole.

I’ve added the full recipe at the bottom of this post and it can be printed out to add it to your favorite recipes…because it will make it into your Top 10 recipes.
Directions:
Brown the sausage. Break the bread apart into small pieces. These two steps are the longest part of the casserole prep. After these to things you’ll mix all the ingredients together.
Pour mixture into a greased 9X13 casserole dish. You can do this two ways: Mix all the ingredients together including the eggs and then pour it into the casserole dish. Or, you can place all the dry ingredients in the casserole dish and then pour the egg/milk mixture on top. It really doesn’t matter.
Bake and enjoy!
The one ingredient you might not have for this casserole is dry mustard. You can find this in the spice section of the grocery store. If you don’t have it, it’s not a deal breaker. You probably wouldn’t even notice if it was missing.
Your family is sure to love this breakfast casserole made with sausage. It’s a winner for sure. This sausage casserole is one of my family’s favorite breakfasts. I often make two of these and take them to our Christmas brunch with the family. When I do, I always use my pretty casserole carrier that holds two casserole dishes at a time.
Can you freeze a Sausage Breakfast Casserole?
If you’re wondering about freezing it, you can make this Sausage, Egg, and Cheese Breakfast Casserole ahead of time and freeze it. Then, thaw it in the refrigerator the night before. Pull it out of the refrigerator in the morning and bring to room temperature for about 30 minutes before baking it. You might have to bake it for a little longer, but you’ll know it’s ready when it starts to brown on top.

Is the bread nessecary or can you do it without and still have the same bake time?
I’ve never tried it without the bread, so I don’t know what to tell you.
I have made it without the bread, it was still a big hit. It’s more like an omelet than a casserole, still yummy.
Do you have to put in in the fridge or can you bake it right away?
You can totally just make and bake it right away. We just do it the night before to eliminate the work in the morning. Hope you enjoy it!
