This casserole shines with fresh ingredients. First, you need eggs. They form the base of your dish. Next, whole milk adds creaminess. Salt and black pepper enhance flavor. Garlic and onion powder bring depth to every bite.
Cheese adds richness. I love using sharp cheddar and mozzarella—they melt beautifully together. Day-old bread is key. It soaks up the egg mixture, creating a soft texture.
For protein, you can add cooked sausage or go veggie with bell peppers and spinach. Fresh parsley brightens the dish and adds color. Each ingredient plays a role in making this casserole comforting and delicious.

Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 350°F (175°C). Grab a 9x13-inch baking dish and grease it lightly with non-stick spray or butter.
2. In a large mixing bowl, whisk together 8 large eggs and 2 cups of whole milk. Add in 1 teaspoon of salt, 1/2 teaspoon of black pepper, 1 teaspoon of garlic powder, and 1 teaspoon of onion powder. Mix until smooth.
3. Take 4 cups of day-old bread and cut it into 1-inch cubes. Evenly spread the cubed bread across the bottom of your prepared baking dish.
4. Choose either 1 cup of cooked and crumbled sausage or a mix of diced bell peppers and spinach. Sprinkle this evenly over the bread layer.
Baking Instructions
1. Carefully pour the egg mixture over your layered bread and sausage or vegetables. Use a spatula to press down gently on the bread. Make sure all pieces soak in the egg mixture.
2. Generously top the casserole with 1 cup of shredded sharp cheddar cheese and 1 cup of shredded mozzarella cheese. Spread it evenly across the surface.
3. Cover the baking dish tightly with aluminum foil. Place it in the refrigerator for at least 1 hour, or better yet, overnight. This helps the flavors meld together.
4. When you're ready to bake, take the casserole out of the fridge. Let it sit at room temperature for about 15 minutes. Bake covered with foil for 30 minutes. After that, remove the foil and continue baking for another 15-20 minutes. The cheese should be bubbly and golden.
Final Touches
1. Once baked, carefully remove the casserole from the oven. Let it cool for a few minutes before slicing it into generous portions.
2. For a lovely presentation, garnish the casserole with freshly chopped parsley right before serving. Enjoy warm slices on festive plates, maybe with a dollop of sour cream or a side of fresh fruit salad.
Tips & Tricks
Make Ahead Suggestions
You can make this casserole the night before. Overnight soaking helps the bread absorb more flavor. It makes the dish taste richer. Just cover it tightly and place it in the fridge. This step is key for great results.
If you want to store it longer, you can freeze it. Wrap the casserole well in plastic wrap and aluminum foil. It can last for up to three months in the freezer. When ready to eat, thaw it in the fridge overnight. Then bake as usual.
Cooking Tips
To ensure even baking, preheat your oven to 350°F (175°C). This step is important for even cooking. Place the casserole in the center of the oven. This helps it bake uniformly.
To avoid soggy bread, use day-old bread. Fresh bread can soak up too much moisture. Cut it into 1-inch cubes to help it mix well with the egg mixture. This keeps your casserole light and fluffy.
Serving Suggestions
Serve your casserole with a dollop of sour cream or a side of fresh fruit salad. These add a nice contrast to the rich flavors. You can also sprinkle extra parsley on top for color.
As for drinks, a warm cup of coffee or hot cocoa pairs well. A glass of fresh orange juice can brighten up the meal too. These drinks enhance the festive spirit of your breakfast table.
Variations
Meat Variations
You can switch up the meat in this casserole. Try different types of sausage. Pork sausage brings a nice flavor. Turkey sausage is a lighter choice. For a spicy kick, use chorizo. You can even mix in bacon bits for extra taste.
If you want more protein options, consider diced ham or cooked chicken. These meats add richness without overpowering the dish. You can blend meats, too! A mix of sausage and ham is very tasty.
Vegetarian Options
This casserole can easily go meatless. Adding more vegetables is a great choice. Bell peppers, spinach, or mushrooms work well. You can sauté them first to enhance their flavors. Try adding zucchini or broccoli for more color and nutrition.
Cheese is key for flavor. You can use different kinds, too. Feta cheese adds a tangy twist. Goat cheese gives a creamy touch. Mixing cheeses can create a unique taste that everyone will love.
Spice Level Adjustments
If you like heat, adjust your spices. Adding hot sauce to the egg mix gives it a kick. You can also try red pepper flakes. They add warmth without overpowering the dish.
For a fresh flavor, include diced jalapeños. These peppers bring both heat and a nice crunch. Always taste as you go. This way, you can find the right balance for your family.
Storage Info
Refrigeration
Your Christmas Morning Egg and Cheese Casserole lasts up to 3 days in the fridge. To store leftovers, let the casserole cool down first. Then, cover it tightly with plastic wrap or aluminum foil. This keeps it fresh and avoids any bad smells in your fridge.
Freezing Instructions
You can freeze the casserole for up to 2 months. To freeze, cut it into portions and wrap each piece in plastic wrap. Then, place the wrapped portions in a freezer-safe bag or container. Be sure to label the bag with the date. When ready to eat, move a portion to the fridge overnight to thaw.
Reheating Guidelines
You can reheat it in the microwave or oven. For the microwave, place a slice on a plate and heat for 1-2 minutes. If you want the crust to stay crispy, use the oven. Preheat the oven to 350°F. Then, cover the casserole with foil and bake for 15-20 minutes. This keeps the cheese melty and the bread nice. Enjoy your warm, cheesy breakfast!
FAQs
What can I substitute for milk in the casserole?
