Step‑by‑Step Instructions for Hearty Make-Ahead Christmas Breakfast Casserole
Step 1: Cook the Sausage
In a large skillet over medium heat, add your choice of sausage, breaking it apart with a wooden spoon. Cook for about 7-10 minutes until browned and crumbled, stirring occasionally to ensure even browning. Once fully cooked, transfer the sausage onto a paper towel-lined plate to drain any excess grease, leaving the flavorful bits in the skillet for the next step.
Step 2: Sauté the Vegetables
In the same skillet, add chopped onions and peppers, cooking them over medium heat for about 5 minutes. Sauté until the onions become translucent and the peppers soften slightly, releasing their vibrant colors and sweet aroma. Stir frequently to prevent sticking, infusing your kitchen with the delightful scents that warm the spirit of the holiday season.
Step 3: Prepare the Baking Dish
Grease a large 9×13-inch baking dish with butter or cooking spray to ensure easy removal later. Next, even layer the cubed bread across the bottom of the dish, creating a sturdy base for your Christmas breakfast casserole. This will soak up all the flavors from the filling ingredients, creating a delightful texture by the time it’s baked.
Step 4: Layer the Filling
Spread the cooked sausage evenly over the layer of cubed bread in the baking dish. Then, add the sautéed vegetable mixture on top of the sausage, distributing it evenly. The combination of savory sausage with fresh vegetables makes this casserole not only hearty but also colorful, elevating it to a festive centerpiece for your holiday table.
Step 5: Add Cheese
Sprinkle a generous layer of shredded cheddar cheese across the top of the sausage and vegetable mixture. This cheesy layer adds creaminess and flavor to your Hearty Make-Ahead Christmas Breakfast Casserole, ensuring that every bite is a gooey delight when baked to perfection.
Step 6: Whisk the Egg Mixture
In a medium bowl, whisk together eggs, milk, salt, and pepper until well combined. Make sure the mixture is frothy to ensure a fluffy texture in the casserole. Pouring this mixture over your layered ingredients will bind everything together, creating that comforting mouthfeel we all adore in a delicious breakfast casserole.
Step 7: Assemble and Refrigerate
Pour the egg mixture slowly and evenly over the casserole layers, allowing it to seep into the bread below. At this point, you can cover your dish with plastic wrap or aluminum foil and refrigerate overnight. This make-ahead option is perfect for busy holiday mornings when you want to minimize prep time and maximize family time.
Step 8: Preheat the Oven
On the morning of your gathering, preheat your oven to 350°F (175°C). This ensures that your oven is at the perfect temperature to bake your Hearty Make-Ahead Christmas Breakfast Casserole evenly, giving it a beautifully golden-brown finish.
Step 9: Bake the Casserole
Place the baking dish in the preheated oven and bake for 45 minutes. The casserole is ready when it’s puffed up, golden brown on top, and the center is set. During the last few minutes of baking, keep an eye on it to achieve that perfect crust without overcooking.
Step 10: Let It Rest
Once baked, remove the casserole from the oven and let it rest for about 5-10 minutes before cutting into portions. This resting time allows the casserole to set, making it easier to serve, and enhances the blend of flavors for your family to enjoy the delightful layers of your Christmas breakfast casserole.

Expert Tips for Christmas Breakfast Casserole
-
Prep Ahead: A key to success is prepping the casserole overnight. This allows flavors to meld, making the Christmas Breakfast Casserole even tastier.
-
Let It Rest: After baking, let the casserole sit for a few minutes before slicing. This enhances the texture, preventing it from falling apart.
-
Avoid Soggy Bread: Use stale or toasted bread when layering; this prevents the bread from becoming overly soggy during baking, maintaining that perfect texture.
-
Customize Wisely: Feel free to add spices or herbs, but avoid overloading the dish with too many ingredients, which can overwhelm the flavor balance.
-
Check for Doneness: Ensure the center is set before removing it from the oven. Gently shake the pan; if it wobbles too much, it needs more time.

Christmas Breakfast Casserole Recipe FAQs
How do I select the best sausage for the casserole?
Absolutely! Look for sausage that’s fresh and flavorful, preferring varieties that are lean but still have a good amount of seasoning. For a heartier flavor, choose pork sausage or ground turkey for a lighter option. Always ensure it’s free of dark spots or unusual odors that indicate it’s past its prime.
What’s the best way to store leftovers?
You can store your leftover Christmas breakfast casserole in an airtight container in the fridge for up to 3 days. When reheating, I recommend using either the microwave for quick individual servings or a preheated oven at 350°F until warmed through, which helps retain that fluffy texture.
Can I freeze the casserole, and how?
Certainly! To freeze your Christmas breakfast casserole, first assemble it without baking, then cover tightly with plastic wrap and aluminum foil. It can stay in the freezer for up to 2 months. When ready to bake, simply thaw it overnight in the refrigerator. Bake in a preheated oven at 350°F for 60-75 minutes, checking to ensure it’s heated through in the center.
What do I do if my casserole seems too soggy?
If your casserole is too soggy, it may be due to using fresh bread instead of stale or toasted bread, which absorbs moisture better. If you notice this happening, you can let it bake for an extra 10-15 minutes uncovered to help evaporate some excess moisture, improving the texture.
Are there any dietary considerations I should keep in mind?
Very! If you have vegetarian guests, consider substituting the sausage with meat-free options or adding more veggies like spinach or mushrooms. Additionally, be mindful of any dairy allergies; you can easily swap out regular milk for a non-dairy alternative. Always let your guests know that the casserole contains eggs and cheese to avoid any allergic reactions.
