Why Make This Christmas Breakfast Feed A Crowd Easy Make Ahead Casserole
Holiday mornings are for making memories, not standing over a hot stove flipping pancakes. This casserole allows you to do all the heavy lifting the night before. Because the bread soaks up the egg mixture overnight, the texture becomes incredibly rich and souffle-like. It easily feeds a large group, making it the perfect solution for hosting guests. Plus, it uses simple pantry staples that you likely already have on hand during the holiday season.
Ingredients
- 1 pound ground breakfast sausage (mild or spicy)
- 10 large eggs
- 3 cups whole milk
- 1 teaspoon dry mustard
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 6 cups cubed French bread or sourdough (about 1-inch cubes)
- 2 cups shredded sharp cheddar cheese
- 1/2 cup sliced green onions (for garnish)
- Non-stick cooking spray
Directions
Step 1: Brown the Sausage
Place a large skillet over medium-high heat. Add the ground breakfast sausage and cook until it is completely browned and crumbled. Use a wooden spoon to break up the meat as it cooks. Once finished, drain the excess grease onto a paper towel-lined plate and set the meat aside to cool slightly.
Step 2: Prepare the Baking Dish
Generously grease a 9×13-inch baking dish with non-stick cooking spray or butter. Distribute the cubed bread evenly across the bottom of the dish. Scatter the cooked sausage over the bread cubes, then sprinkle the shredded cheddar cheese over the top, ensuring even coverage.
Step 3: Whisk the Egg Custard
In a large mixing bowl, crack the 10 eggs and whisk them thoroughly. Add the milk, dry mustard, salt, and black pepper. Whisk the mixture until it is smooth and the spices are well incorporated. This custard will provide the structure and flavor for your casserole.
Step 4: Pour and Refrigerate
Carefully pour the egg mixture over the bread, sausage, and cheese in the baking dish. Use a spatula to gently press down on the bread cubes to ensure they are all submerged or coated. Cover the dish tightly with plastic wrap or aluminum foil and place it in the refrigerator for at least 8 hours, or ideally overnight.
Step 5: Bake and Serve
Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature for about 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 minutes, garnish with green onions, and slice into squares to serve.
Expert Tips for Perfect Christmas Breakfast Feed A Crowd Easy Make Ahead Casserole
To get the best results, use “day-old” or slightly stale bread. Fresh, soft bread can sometimes become too mushy, whereas crusty French bread or sourdough holds its shape beautifully. Always shred your own cheese from a block if possible; pre-shredded cheese is coated in potato starch, which can prevent it from melting smoothly. If you notice the top browning too quickly in the oven, loosely tent a piece of foil over the dish for the last 10 minutes of baking.
Delicious Variations
You can easily customize this recipe to suit your family’s taste. For a “Western Style” casserole, add sautéed bell peppers and onions to the sausage layer. If you prefer a bit of heat, swap the cheddar for pepper jack cheese and add a can of drained diced green chiles. For a vegetarian option, replace the sausage with sautéed mushrooms, spinach, and sun-dried tomatoes. You can also swap the sausage for chopped crispy bacon or diced ham for a different salty kick.

Frequently Asked Questions
Can I bake this immediately instead of waiting overnight?
Yes, you can bake it right away, but the texture will be slightly different. Letting it sit for at least 30 minutes before baking helps the bread absorb the liquid, but the overnight rest provides the best, most cohesive texture.
How long do leftovers stay fresh?
Leftovers will stay fresh in an airtight container in the refrigerator for up to 3 to 4 days. Reheat individual portions in the microwave or the entire dish in the oven at 325°F until warmed through.
Can I freeze this casserole?
You can freeze this casserole either before or after baking. If freezing before, let it thaw completely in the fridge before putting it in the oven. If freezing after, slice it into individual portions and wrap them tightly; they will last up to 2 months.
What is the best bread to use?
A sturdy, crusty bread like French bread, sourdough, or Challah works best. Avoid standard white sandwich bread, as it tends to disintegrate into the egg mixture.
Can I use a dairy-free milk alternative?
Yes, you can use unsweetened almond milk or oat milk. However, the casserole might be slightly less creamy than if you used whole milk or half-and-half.

This Christmas Breakfast Feed A Crowd Easy Make Ahead Casserole is the ultimate holiday gift to yourself. It delivers a high-quality, crowd-pleasing meal with minimal effort on the big day.
