Christmas Breakfast Casserole is one of our favorite make-ahead breakfasts for holiday mornings because it’s hearty, cheesy, and ready to bake when everyone wakes up. Sausage, eggs, half and half, toasted bread cubes, and sharp cheddar cheese come together in a simple 9×13 breakfast bake.
We love assembling this the night before so Christmas morning feels easier and more relaxed. Just pop it in the oven, let it bake until set, and serve warm with fruit, Cinnamon Rolls, Hot Chococolate, or your favorite holiday breakfast sides.
This is our best loved breakfast casserole for Christmas and the one we make the most. Pair it with French Toast Casserole for something both sweet and savory!
Why you’ll love it + Why it works:
- Perfect Make Ahead Meal: Assemble it the night before so breakfast is almost effortless on Christmas morning.

- Holiday Favorite: It’s a dependable recipe that makes Christmas morning feel extra special.
- Simple Ingredients: Everyday pantry staples come together into a rich, flavorful breakfast.
Christmas Breakfast Casserole Ingredients
- Ground pork sausage or maple sausage (1 pound): Adds hearty, savory flavor and makes the casserole filling. Maple sausage adds a subtle sweetness that’s especially delicious for holiday breakfasts.
- Salt (½ teaspoon): Enhances the flavor of all the ingredients.
- Eggs (6, beaten): Forms the rich custard that holds the casserole together and creates a fluffy texture.
- Half and half (1 to 1½ cups): Makes the egg mixture extra creamy and rich. Use the larger amount for a softer casserole.
- White bread (6 slices, toasted and cut into cubes): Soaks up the egg mixture and creates a soft, custardy texture. Toasting the bread helps it hold its shape.
- Sharp cheddar cheese (2 cups, shredded): Adds bold cheesy flavor and creates a delicious golden top. Freshly shredded cheese melts the smoothest.
How to Make Christmas Breakfast Casserole
PREP. Grease a 9×13-inch baking dish, and set aside.
SAUSAGE. In a large skillet, cook sausage over medium heat until browned, and drain.
MIX. In a large bowl, mix the salt, eggs, and half and half. Add the cooked sausage, white bread (cubed), and cheddar cheese. Stir until evenly coated. Pour the mixture into the baking dish.
CHILL. Cover with aluminum foil and chill in the refrigerator for at least 2 hours, or overnight.
BAKE. Preheat the oven to 350°F. Bake the casserole, covered, for 50-60 minutes. Reduce the heat to 325°F. Uncover the casserole and bake for 20-30 additional minutes or until the casserole has set.
Kristyn’s Recipe Tips
- Toast the bread before cubing it so it absorbs the egg mixture without becoming mushy.
- Let the casserole rest for 10 minutes after baking to make slicing and serving easier.
- Use freshly shredded cheddar cheese for the best melting texture and flavor.
- If the top begins browning too quickly during the uncovered bake, loosely tent it with foil.
