Why Make This Christmas Breakfast Casserole Make Ahead Easy Feed A Crowd

This recipe is a game-changer for holiday hosting. First, the “make-ahead” factor means you do all the heavy lifting and cleaning the night before. Your kitchen stays clean on Christmas morning! Second, it is designed specifically to feed a crowd, fitting perfectly into a standard 9×13 baking dish to satisfy up to a dozen hungry guests. Finally, the texture is unbeatable. Because the bread soaks in the egg mixture overnight, it transforms into a savory, bread-pudding-like consistency that is crispy on top and tender in the middle. It is a complete meal in one pan that everyone from toddlers to grandparents will love.

Ingredients

• 1 lb ground breakfast sausage (mild or spicy)
• 10 large eggs
• 3 cups whole milk
• 1/2 cup heavy cream
• 1 teaspoon dry mustard powder
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon garlic powder
• 8 cups cubed sturdy bread (sourdough, French bread, or brioche)
• 2 cups shredded sharp cheddar cheese
• 1/2 cup shredded Monterey Jack cheese
• 2 tablespoons fresh chives, chopped (for garnish)

Directions

Step 1: Brown the Sausage and Prep Bread

Place a large skillet over medium-high heat. Add the ground breakfast sausage and cook until browned and crumbled, about 8-10 minutes. Drain the excess grease thoroughly on a paper towel-lined plate. While the sausage cools slightly, cut your bread into 1-inch cubes. If the bread is very fresh, you can toast the cubes in a low oven for 10 minutes to dry them out, which prevents the casserole from becoming soggy.

Step 2: Whisk the Egg Custard

In a large mixing bowl, crack the 10 eggs and whisk them vigorously until well combined. Pour in the whole milk and heavy cream. Add the dry mustard powder, salt, black pepper, and garlic powder. Whisk again until the spices are evenly distributed throughout the liquid. This “custard” is what gives the casserole its rich, fluffy structure.

Step 3: Assemble the Layers

Grease a 9×13 inch baking dish generously with butter or non-stick spray. Spread the bread cubes evenly across the bottom of the dish. Sprinkle the cooked sausage over the bread, followed by both types of shredded cheese. Pour the egg mixture slowly over the top, ensuring all the bread pieces get moistened. Use a spatula to gently press down on any dry bread cubes to submerge them.

Step 4: The Overnight Soak

Cover the baking dish tightly with aluminum foil or plastic wrap. Place it in the refrigerator for at least 4 hours, though overnight is highly recommended. This rest period allows the bread to absorb the custard completely, creating that signature melt-in-your-mouth texture.

Step 5: Bake and Serve

Preheat your oven to 375°F (190°C). Remove the casserole from the fridge and let it sit on the counter for 20 minutes to take the chill off. Bake covered with foil for 30 minutes. Remove the foil and bake for another 20 minutes, or until the top is golden brown and the center is set (it should not jiggle when shaken). Let it rest for 10 minutes before slicing. Garnish with fresh chives and serve hot.

Expert Tips for Perfect Christmas Breakfast Casserole Make Ahead Easy Feed A Crowd

• Use Stale Bread: Use bread that is a day or two old. Fresh, soft sandwich bread tends to turn into mush. Sourdough provides a great structural integrity and a slight tang.
• Drain the Meat: Ensure you drain every bit of fat from the sausage. If you skip this, the grease will pool on top of the casserole during baking.
• Room Temperature Start: Never put a glass baking dish directly from the cold fridge into a hot oven, as it could shatter. Always let it sit out for a few minutes first.
• Check for Doneness: Insert a knife into the center; if it comes out clean without liquid egg, it is finished.

Delicious Variations

• The Veggie Delight: Swap the sausage for sautéed spinach, mushrooms, and red bell peppers for a vegetarian-friendly version.
• The Southwest Kick: Use chorizo instead of breakfast sausage and add a small can of diced green chiles to the egg mixture. Serve with salsa and avocado.
• Meat Lover’s Special: Use a combination of cooked bacon bits, diced ham, and sausage for an extra protein-packed holiday meal.
• Swiss and Mushroom: Replace the cheddar with Swiss cheese and add caramelized onions and sautéed cremini mushrooms for a more sophisticated flavor profile.

Frequently Asked Questions

Can I freeze this casserole before baking?

Yes! You can assemble the casserole, cover it tightly with plastic wrap and then foil, and freeze it for up to two months. Thaw it completely in the refrigerator for 24 hours before baking as directed.

What is the best bread to use?

A crusty French loaf, sourdough, or Challah are the best choices. These breads have enough density to hold up to the liquid without disintegrating into a paste.

Can I make this the same day instead of overnight?

You can, but you should let it soak for at least 1 to 2 hours in the fridge before baking. If you bake it immediately, the bread won’t have time to absorb the custard, and you’ll end up with dry bread on top and a pool of egg at the bottom.

How do I store leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual slices in the microwave for 1 minute or in a 350°F oven until warmed through.

Can I use egg whites instead of whole eggs?

You can substitute some of the whole eggs with egg whites (typically 1/4 cup of egg whites equals one egg), but the casserole will be less rich and slightly less fluffy.
