The Ingredients

Here’s what you’ll need to make the Overnight Croissant Breakfast Casserole with Sawmill Gravy (the exact measurements and full recipe instructions are below in the printable recipe card):

  • Olive oil
  • Small onion
  • 1-pound roll of breakfast sausage – we suggest you use a mild flavor. Don’t use an Italian flavor of sausage; it’s not right for this recipe.
  • Croissants – use butter croissants you find in the bakery section of the grocery store. Be sure you don’t use something like a refrigerated crescent roll as this will not work for this recipe.
  • Shredded cheddar cheese
  • Eggs
  • Heavy whipping cream
  • Milk – whole milk is recommended
  • Dry mustard powder
  • Salt
  • Black pepper
  • Paprika
  • Garlic powder
  • Butter
  • Flour

How to Make Overnight Croissant Breakfast Casserole with Sawmill Gravy

You’ll want to make this recipe in the evening the night before you plan to bake the casserole. Start by tearing the croissants into large bite sized pieces.

Next, in a large mixing bowl, whisk together the eggs, heavy cream, part of the milk, and the seasonings.

In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook until soft and translucent. Crumble the sausage into the pan and cook until completely browned. Drain off the fat and reserve this in the refrigerator to use in the gravy you’ll make the next morning (yes, the fat from the sausage makes the gravy extra tasty!).

Add the cooked sausage and cheese to the torn croissants and mix well.

Pour the sausage and croissant mixture into a 9×13-inch glass baking dish that has been greased with non-stick cooking spray. Pour the egg and milk mixture over top .

Cover the casserole with plastic wrap or foil and refrigerate overnight.

The next morning, bake the casserole at 350ºF for 35-45 minutes until golden brown.

Making Sawmill Gravy

While the casserole is baking, melt 1 tablespoon of the reserved cooking fat and 2 tablespoons of butter in a large skillet over medium heat. Add 3 tablespoons of all-purpose flour and stir until combined. Let this mixture simmer for 1 minute.

Slowly begin adding the milk, whisking well as you go, until all of the milk is incorporated. Simmer the sauce on low until thickened, then add salt and pepper to taste.

Allow the breakfast casserole to cool slightly in the pan for about 5 minutes, then cut into slices and serve with the warm sawmill gravy.

How to Store Leftovers

Keep the leftover casserole in and airtight container in the refrigerator for up to three days. The gravy should be stored in a separate container and also keeps in the refrigerator for about three days.
