Ingredients for Christmas Breakfast Casserole

• 1 pound breakfast sausage (pork or turkey)
• 6 large eggs
• 2 cups whole milk
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon garlic powder (optional)
• 4 cups cubed French bread (or any crusty bread)
• 1 1/2 cups shredded sharp cheddar cheese
• 1/2 cup shredded mozzarella cheese
• 1 tablespoon chopped fresh parsley (optional, for garnish)
• Nonstick cooking spray or butter for greasing the dish

Step 1: Prepare the Sausage

Start by browning the breakfast sausage in a skillet over medium heat. Break it up into crumbles as it cooks until it’s fully browned and no longer pink—about 6–8 minutes. Once done, drain any excess fat and set the sausage aside to cool slightly. This adds a rich, savory base to your casserole.

---

Step 2: Mix the Egg Base

In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and garlic powder (if using). This will form the custard-like mixture that binds the casserole and creates that fluffy, creamy texture in every bite.

---

Step 3: Assemble the Casserole

Grease a 9×13-inch baking dish with nonstick spray or butter. Spread the bread cubes evenly across the bottom of the dish. Then sprinkle the cooked sausage over the bread, followed by the cheddar and mozzarella cheeses. Pour the egg mixture evenly over the top, ensuring all the bread gets soaked. Gently press down with a spatula to help the liquid absorb.

---

Step 4: Let It Soak (Overnight or 30 Minutes)

For best results, cover the casserole tightly with plastic wrap or foil and refrigerate overnight. This allows the bread to fully absorb the egg mixture. If you’re short on time, let it sit for at least 30 minutes before baking.

---

Step 5: Bake to Golden Perfection

Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator while the oven heats. Bake uncovered for 45–50 minutes, or until the top is golden brown and a knife inserted in the center comes out clean. If the top starts to brown too quickly, cover loosely with foil during the last 10 minutes.

---

Step 6: Garnish and Serve

Once baked, let the casserole rest for 5–10 minutes to set. Sprinkle with fresh parsley for a festive touch. Slice into squares and serve warm with hot coffee, fresh fruit, or orange juice to complete your cozy Christmas breakfast.

Frequently Asked Questions

1. Can I make this casserole vegetarian?

Yes! Simply replace the sausage with plant-based meat or sautéed veggies like mushrooms, spinach, and bell peppers.

2. Can I use a different type of bread?

Absolutely. Brioche, sourdough, or even croissants add a rich texture and flavor.

3. How far in advance can I prepare it?

You can prep it up to 24 hours in advance and keep it refrigerated until ready to bake.

4. Can I double the recipe?

Yes, just use a larger baking dish and add 10–15 extra minutes to the baking time. Keep an eye on the center for doneness.

5. What cheeses work best?

Sharp cheddar adds flavor, while mozzarella gives you that gooey melt. You can also use Monterey Jack, Swiss, or even a little parmesan.

6. Is it okay to bake it right away?

You can, but letting it rest at least 30 minutes or overnight ensures the bread absorbs the egg mixture for better texture.

7. How do I know when it’s done baking?

The casserole is done when the top is golden and a knife inserted in the center comes out clean.

8. Can I add potatoes or hash browns?

Yes! Layer in shredded hash browns or cubed potatoes with the bread for extra heartiness.
