Ingredients

• 1 lb ground breakfast sausage (mild or spicy)
• 10 large eggs
• 2 cups whole milk
• 1 teaspoon dry mustard
• 1/2 teaspoon onion powder
• Salt and black pepper to taste
• 6 cups cubed sourdough or French bread (about 1-inch pieces)
• 2 cups shredded sharp cheddar cheese
• 1 red bell pepper, diced
• 3 green onions, sliced
• Fresh parsley 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 no pink remains. Use a wooden spoon to crumble the meat into small pieces as it cooks. Once finished, drain the excess grease onto a paper towel and let the meat cool slightly.

Step 2: Prepare the Egg Mixture

In a large mixing bowl, crack the 10 eggs. Whisk them vigorously until the yolks and whites are fully combined. Pour in the milk, dry mustard, onion powder, salt, and pepper. Continue whisking until the mixture is smooth and the spices are evenly distributed.

Step 3: Layer the Ingredients

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 browned sausage, diced red peppers, and half of the shredded cheese over the bread. Gently toss them together so the ingredients are well-mixed within the dish.

Step 4: Soak and Refrigerate

Pour the egg mixture slowly over the bread and sausage layers, ensuring every piece of bread is moistened. Sprinkle the remaining cheese and green onions on top. Cover the dish tightly with plastic wrap or aluminum foil and place it in the refrigerator for at least 4 hours, or preferably overnight.

Step 5: Bake to Perfection

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. The top should be golden brown, and the center should be set. Let it rest for 10 minutes before slicing and serving.

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

For the best results, use “day-old” bread. Stale bread absorbs the egg custard much better than fresh, soft bread, which can lead to a soggy texture. If your bread is too fresh, toast the cubes in the oven for 10 minutes before assembling. Additionally, always shred your own cheese from a block. Pre-shredded cheeses are coated in potato starch to prevent clumping, which can stop them from melting smoothly into the casserole. Finally, ensure you let the casserole rest after baking; this helps the structure set so you get clean, beautiful squares when serving.

Delicious Variations

You can easily customize this recipe to suit your family’s preferences. If you prefer a vegetarian version, swap the sausage for sautéed mushrooms, spinach, and sun-dried tomatoes. For a kick of heat, use “hot” breakfast sausage and add diced jalapeños to the egg mixture. You can also swap the bread for frozen tater tots or shredded hash browns if you prefer a gluten-free-friendly base (just check your labels!). If you want an even richer flavor, replace one cup of milk with heavy cream.

Frequently Asked Questions

Can I freeze this casserole before baking?

Yes, you can freeze the assembled casserole. Wrap it tightly with a double layer of plastic wrap and foil. It will stay fresh for up to two months. Thaw it completely in the refrigerator for 24 hours before baking as directed.

How long can I keep leftovers in the fridge?

Leftovers can be stored in an airtight container in the refrigerator for up to 3 to 4 days. It actually tastes great the next day as the flavors continue to develop.

What is the best type of bread to use?

Sourdough or a crusty French loaf are the best choices. They have a sturdy structure that holds up well under the weight of the eggs and milk without turning into mush.

Can I make this on the same day instead of ahead of time?

You can, but you should let the assembled dish sit for at least 30 minutes before putting it in the oven. This gives the bread enough time to soak up some of the liquid.

How do I know when the casserole is fully cooked?

Insert a knife or toothpick into the center of the dish. If it comes out clean and no liquid egg pools in the hole, it is ready. The top should also be puffed up and slightly jiggly but firm.
