## Ingredients You’ll Need

Now that we’ve established why this casserole is a Christmas morning essential, let’s take a look at the ingredients you’ll need to bring this culinary masterpiece to life:

* **1 pound breakfast sausage:** Choose your favorite type of sausage – mild, spicy, or sweet Italian. Remove the casings and crumble the sausage before cooking. For a lighter option, you can use turkey sausage or plant-based sausage alternatives.
* **1 loaf (1 pound) bread:** Day-old bread works best for this recipe, as it will soak up the egg mixture without becoming mushy. You can use any type of bread you prefer, such as French bread, sourdough, or Italian bread. Cut the bread into 1-inch cubes.
* **6 large eggs:** Eggs are the foundation of the casserole, providing structure and richness. Use fresh, high-quality eggs for the best results.
* **2 cups milk:** Milk adds moisture and creaminess to the egg mixture. You can use whole milk, 2% milk, or even a dairy-free alternative like almond milk or soy milk.
* **1 cup shredded cheddar cheese:** Cheddar cheese provides a classic cheesy flavor that complements the sausage and eggs perfectly. You can use sharp cheddar, mild cheddar, or a blend of both. Feel free to experiment with other cheeses like Monterey Jack, Gruyere, or pepper jack.
* **1/2 cup shredded mozzarella cheese:** Mozzarella cheese adds a creamy, stretchy texture to the casserole. It melts beautifully and creates a delightful cheese pull.
* **1/4 cup chopped onion:** Onion adds a savory depth of flavor to the casserole. You can use yellow onion, white onion, or even red onion. Sauté the onion before adding it to the casserole to soften it and mellow its flavor.
* **1/4 cup chopped green bell pepper:** Green bell pepper adds a touch of sweetness and crunch to the casserole. You can use other colors of bell pepper as well, such as red, yellow, or orange.
* **1 teaspoon Dijon mustard:** Dijon mustard adds a tangy kick to the egg mixture. It complements the savory sausage and cheese flavors perfectly. If you don’t have Dijon mustard, you can use yellow mustard or even a dash of hot sauce.
* **1/2 teaspoon salt:** Salt enhances the flavors of all the other ingredients. Use kosher salt or sea salt for the best results.
* **1/4 teaspoon black pepper:** Black pepper adds a touch of spice to the casserole. Use freshly ground black pepper for the best flavor.
* **1/4 teaspoon garlic powder:** Garlic powder adds a savory aroma and flavor to the casserole. You can use fresh garlic instead, but be sure to mince it finely before adding it to the casserole.
* **Optional additions:** Feel free to add other ingredients to your casserole, such as mushrooms, spinach, tomatoes, or your favorite herbs and spices.

## Step-by-Step Instructions

Now that you have all your ingredients assembled, let’s get started on creating your Christmas breakfast sausage casserole. Follow these step-by-step instructions for a foolproof recipe:

**Step 1: Cook the Sausage**

* Heat a large skillet over medium heat.
* Remove the sausage from its casing and crumble it into the skillet.
* Cook the sausage until it is browned and cooked through, breaking it up with a spoon as it cooks.
* Drain off any excess grease.
* Set the cooked sausage aside to cool slightly.

**Step 2: Prepare the Bread**

* Cut the bread into 1-inch cubes.
* Place the bread cubes in a large bowl.

**Step 3: Sauté the Vegetables (Optional)**

* If using, heat a tablespoon of olive oil in the same skillet you used to cook the sausage.
* Add the chopped onion and green bell pepper to the skillet.
* Sauté the vegetables until they are softened, about 5-7 minutes.
* Add the sautéed vegetables to the bowl with the bread cubes.

**Step 4: Make the Egg Mixture**

* In a separate large bowl, whisk together the eggs, milk, Dijon mustard, salt, pepper, and garlic powder.
* Whisk until the mixture is smooth and well combined.

**Step 5: Assemble the Casserole**

* Add the cooked sausage and shredded cheddar cheese and mozzarella cheese to the bowl with the bread cubes and vegetables.
* Pour the egg mixture over the bread, sausage, and cheese mixture.
* Gently toss everything together until the bread is evenly coated with the egg mixture.
* Press down on the mixture to ensure that the bread is submerged in the egg mixture.

**Step 6: Refrigerate (Optional)**

* For best results, cover the casserole with plastic wrap and refrigerate it overnight or for at least 2 hours.
* This allows the bread to soak up the egg mixture completely, resulting in a more flavorful and moist casserole.
* If you are short on time, you can bake the casserole immediately, but it may not be as moist and flavorful.

**Step 7: Bake the Casserole**

* Preheat your oven to 350°F (175°C).
* Grease a 9×13 inch baking dish with butter or cooking spray.
* Pour the casserole mixture into the prepared baking dish.
* Bake for 45-55 minutes, or until the casserole is golden brown and set.
* To check for doneness, insert a knife into the center of the casserole. If the knife comes out clean, the casserole is done.
* If the top of the casserole is browning too quickly, you can cover it with aluminum foil during the last 15-20 minutes of baking.

**Step 8: Let it Rest**

* Remove the casserole from the oven and let it rest for 10-15 minutes before serving.
* This allows the casserole to set up and makes it easier to cut and serve.

**Step 9: Serve and Enjoy!**

* Cut the casserole into squares and serve warm.
* Garnish with fresh parsley or chives, if desired.
* Serve with your favorite breakfast sides, such as fruit salad, yogurt, or toast.
* Enjoy your delicious and festive Christmas breakfast sausage casserole!

## Tips and Tricks for the Perfect Casserole

To ensure that your Christmas breakfast sausage casserole is a resounding success, here are some helpful tips and tricks:

* **Use day-old bread:** Day-old bread is slightly drier, which allows it to absorb the egg mixture without becoming mushy.
* **Don’t overcook the sausage:** Overcooked sausage can become dry and tough. Cook the sausage until it is browned and cooked through, but avoid overcooking it.
* **Sauté the vegetables:** Sautéing the vegetables before adding them to the casserole softens them and mellows their flavor.
* **Refrigerate the casserole:** Refrigerating the casserole overnight or for at least 2 hours allows the bread to soak up the egg mixture completely, resulting in a more flavorful and moist casserole.
* **Grease the baking dish:** Greasing the baking dish prevents the casserole from sticking and makes it easier to remove from the dish.
* **Don’t overbake the casserole:** Overbaking the casserole can make it dry and tough. Bake the casserole until it is golden brown and set, but avoid overbaking it.
* **Let the casserole rest:** Letting the casserole rest for 10-15 minutes before serving allows it to set up and makes it easier to cut and serve.
