Easy Overnight Sausage Breakfast Casserole

We are big fans of breakfast casseroles at our house. We love them for breakfast, lunch, and dinner. This Sausage Croissant Breakfast Casserole is one of our favorites! Flaky croissants, sausage, and cheese baked in a creamy egg custard. This casserole is seriously delicious! We have made this casserole several times over the holidays and can't get enough of it. All you need is some fruit and a sweet roll and you are set!

How to Make Sausage Croissant Breakfast Casserole

This Sausage Croissant Breakfast Casserole is very easy to make. This recipe does require a bit of planning because the casserole needs to be assembled in advance and refrigerated at least 8 hours. This allows the yummy egg mixture to soak into the croissants.

To make the casserole, start with chopping some croissants and placing them in a 9-inch square baking dish. Next, cook a package of breakfast sausage in a skillet. Sprinkle the cooked sausage and some shredded cheese on top of the croissants. Finally, whisk together eggs, half-and-half, and dry mustard. Pour the egg mixture over the croissants. Cover the casserole and refrigerate overnight. 

Tips for Making Overnight Sausage Croissant Breakfast Casserole

  • I used a roll of Jimmy Dean sausage. You can use regular or hot sausage. 
  • Can substitute turkey sausage for pork sausage.
  • Can substitute heavy cream or whole milk for half-and-half.
  • Make sure to use bakery croissants. This recipe does NOT use refrigerated crescent rolls. Croissants and crescent rolls are NOT the same thing. Make sure to buy croissants from the bakery.
  • Can use any cheese you prefer - gouda, pepper jack, Monterey jack, or Swiss are good.
  • Can assemble and refrigerate up to 24-hours before baking.
  • Can double the recipe and bake in a 9x13-inch baking dish for a crowd. You may need to add 10 to 15 minutes to the cooking time to ensure the eggs are set.

Can You Freeze Sausage Croissant Breakfast Casserole?

You can make this Sausage Croissant Breakfast Casserole in advance and freeze unbaked or baked. To bake the casserole after freezing, thaw completely in the refrigerator and bake as directed below. To reheat after freezing, thaw completely in the refrigerator and reheat in the microwave or covered in the oven. I suggest reheating at 350ºF for about 30 minutes.
