Why Make This Christmas Breakfast Casserole Make Ahead Easy
This recipe is a holiday game-changer because it eliminates the morning kitchen chaos. By preparing the casserole the night before, the bread has ample time to soak up the savory egg custard, resulting in a texture that is light and fluffy rather than soggy. It is a crowd-pleaser that combines classic breakfast flavors—savory sausage, sharp cheddar, and buttery bread. Plus, it is highly customizable, allowing you to use whatever ingredients you have on hand while still looking like a gourmet centerpiece on your holiday table.
Ingredients
- 1 lb ground breakfast sausage (mild or spicy)
- 6 cups dry bread cubes (French bread or sourdough work best)
- 2 cups shredded sharp cheddar cheese
- 8 large eggs
- 2 cups whole milk
- 1 teaspoon dry mustard powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 cup diced green bell peppers (optional for color)
- 1/4 cup chopped green onions for garnish
Directions
Step 1: Brown the Sausage
Place a large skillet over medium-high heat. Add the ground sausage and cook until it is completely browned and crumbled. Use a wooden spoon to break the meat into small pieces as it cooks. Once finished, drain the excess grease onto a paper towel-lined plate to keep the casserole from becoming too oily.
Step 2: Prepare the Casserole Base
Grease a 9×13-inch baking dish with butter or non-stick cooking spray. Spread the bread cubes evenly across the bottom of the dish. Sprinkle the cooked sausage and diced bell peppers over the bread, then top everything with the shredded cheddar cheese. Toss the ingredients gently to ensure even distribution.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, crack the eight eggs and whisk them thoroughly. Pour in the milk, dry mustard, salt, and pepper. Continue whisking until the mixture is smooth and the seasonings are well incorporated. The mustard powder is the secret ingredient that provides a subtle tang and depth of flavor.
Step 4: Soak and Chill
Pour the egg mixture slowly over the bread and meat in the baking dish. Press down lightly with a spatula to make sure every piece of bread is submerged. Cover the dish tightly with plastic wrap or aluminum foil and refrigerate it for at least 4 hours, or ideally overnight.
Step 5: Bake to Perfection
On Christmas morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for 20 minutes while the oven heats. Bake uncovered for 45 to 50 minutes, or until the top is golden brown and the center is set. Let it rest for 5 to 10 minutes before slicing.
Expert Tips for Perfect Christmas Breakfast Casserole Make Ahead Easy
To achieve the best results, use “day-old” or slightly stale bread. Fresh bread can sometimes turn mushy, whereas drier bread holds its shape and creates a better structure. If your bread is fresh, toast the cubes in the oven for 10 minutes before assembling. Additionally, always grate your cheese from a block. Pre-shredded cheese is coated in potato starch to prevent clumping, which can affect how smoothly it melts into the egg mixture. Finally, do not skip the resting period after baking; it allows the custard to set so you get clean, beautiful slices.
Delicious Variations
You can easily adapt this recipe to suit your family’s tastes. For a vegetarian option, swap the sausage for sautéed mushrooms, spinach, and sun-dried tomatoes. If you want a kick of heat, use “hot” breakfast sausage and add a few diced jalapeños. For a different texture, replace the bread cubes with a layer of frozen tater tots or shredded hashbrowns. You can also experiment with different cheeses like Gruyère for a sophisticated touch or Pepper Jack for a zesty flavor profile.
Frequently Asked Questions
Can I use milk alternatives like almond or oat milk?
Yes, you can use unsweetened non-dairy milks. However, keep in mind that whole milk provides a richness and creaminess that lighter alternatives may lack. Avoid using flavored or sweetened milks as they will clash with the savory sausage.
How long can this stay in the refrigerator before baking?
You can prepare this casserole up to 24 hours in advance. If you leave it longer than that, the bread may start to break down too much, losing the desired texture.
Can I freeze the Christmas Breakfast Casserole?
Yes! You can freeze this casserole either before or after baking. If freezing before, wrap it tightly in multiple layers of foil. Thaw it completely in the fridge before baking. If freezing after baking, cut it into individual portions for easy reheating.
What is the best way to reheat leftovers?
Reheat individual slices in the microwave for 1-2 minutes. For the best texture, place the casserole back in a 350°F oven for 15 minutes until warmed through; this helps keep the edges crispy.
Can I make this if I forgot to prep it the night before?
While the overnight soak is recommended for the best flavor, you can bake it after letting it sit for just 30 to 60 minutes. The bread won’t be quite as soft, but it will still be delicious.

This Christmas Breakfast Casserole Make Ahead Easy is the perfect solution for a relaxing and delicious holiday morning.
