* **1/4 teaspoon red pepper flakes:** Optional, for a touch of heat.
* **8 large eggs:** The base of the creamy egg custard.
* **1 cup milk:** Whole milk or half-and-half will create a richer custard.
* **1/2 cup shredded cheddar cheese:** Adds a sharp and cheesy flavor. You can use other types of cheese, such as Gruyere or Monterey Jack.
* **Salt and pepper to taste:** To season the casserole to perfection.
* **2 tablespoons olive oil:** For sautéing the vegetables.
* **Optional garnishes:** Fresh herbs (such as parsley or chives), shredded cheese, or a dollop of sour cream.

## Step-by-Step Instructions

Follow these detailed instructions to create a Holiday Sausage and Sweet Potato Breakfast Casserole that will impress your family and friends.

**Step 1: Prepare the Sweet Potatoes**

1. Preheat your oven to 400°F (200°C). This initial roasting step helps to soften the sweet potatoes and enhances their natural sweetness.
2. Peel and dice the sweet potatoes into small, even pieces (about 1/2-inch cubes). Uniformity in size is key for even cooking.
3. In a large bowl, toss the diced sweet potatoes with 1 tablespoon of olive oil, salt, and pepper. Ensure the sweet potatoes are evenly coated with the oil and seasoning. This will help them roast properly and develop a delicious flavor.
4. Spread the sweet potatoes in a single layer on a baking sheet lined with parchment paper. Parchment paper prevents sticking and makes for easy cleanup.
5. Roast the sweet potatoes for 20-25 minutes, or until they are tender and slightly browned. Stir them halfway through to ensure even cooking. The sweet potatoes should be easily pierced with a fork when they are done.
6. Remove the roasted sweet potatoes from the oven and set them aside to cool slightly.

**Step 2: Cook the Sausage and Vegetables**

1. While the sweet potatoes are roasting, prepare the sausage and vegetables. In a large skillet over medium heat, add the remaining 1 tablespoon of olive oil.
2. Remove the sausage from its casing (if applicable) and crumble it into the skillet. Cook the sausage, breaking it up with a spoon, until it is browned and cooked through. Make sure there are no pink pieces of sausage remaining.
3. Once the sausage is cooked, remove it from the skillet and set it aside. Leave any rendered fat in the skillet, as it will add flavor to the vegetables.
4. Add the diced onion and bell pepper to the skillet and cook over medium heat until they are softened, about 5-7 minutes. Stir them occasionally to prevent burning. The onions should become translucent and the bell peppers should soften slightly.
5. Add the minced garlic, dried thyme, dried sage, and red pepper flakes (if using) to the skillet. Cook for 1 minute more, stirring constantly, until the garlic is fragrant. This will release the aroma of the spices and infuse the vegetables with flavor.
6. Remove the skillet from the heat and set it aside to cool slightly.

**Step 3: Prepare the Egg Custard**

1. In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined. Make sure the eggs are thoroughly mixed with the milk to create a smooth custard.
2. Taste the egg custard and adjust the seasoning as needed. You may want to add a pinch more salt or pepper to enhance the flavor.

**Step 4: Assemble the Casserole**

1. Grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking to the dish.
2. In the prepared baking dish, layer the roasted sweet potatoes, cooked sausage, and sautéed vegetables. Distribute the ingredients evenly across the dish to ensure a balanced flavor in every bite.
3. Pour the egg custard over the layers of sweet potatoes, sausage, and vegetables. Make sure the custard evenly covers all the ingredients. Gently press down on the ingredients to ensure they are submerged in the custard.
4. Sprinkle the shredded cheddar cheese evenly over the top of the casserole. The cheese will melt and create a golden-brown crust.

**Step 5: Bake the Casserole**

1. Preheat your oven to 350°F (175°C). Make sure the oven is fully preheated before placing the casserole inside.
2. Bake the casserole for 45-50 minutes, or until the custard is set and the cheese is melted and golden brown. The center of the casserole should be firm to the touch and not jiggly.
3. If the cheese starts to brown too quickly, you can cover the casserole with aluminum foil for the last 15 minutes of baking.
4. Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This will allow the custard to set further and make it easier to slice.

**Step 6: Garnish and Serve**

1. Garnish the casserole with fresh herbs, such as parsley or chives, for a pop of color and flavor.
2. You can also add a dollop of sour cream or a sprinkle of extra cheese before serving.
3. Slice the casserole into squares and serve warm. Enjoy!

## Tips and Variations

* **Use different types of sausage:** Experiment with different types of sausage, such as Italian sausage, chorizo, or turkey sausage.
* **Add other vegetables:** Feel free to add other vegetables to the casserole, such as mushrooms, spinach, or kale.
* **Make it vegetarian:** Omit the sausage and add more vegetables, such as roasted broccoli or bell peppers, for a vegetarian option.
* **Use different types of cheese:** Try using Gruyere, Monterey Jack, or pepper jack cheese for a different flavor profile.
* **Add a crunchy topping:** Top the casserole with a mixture of breadcrumbs, melted butter, and Parmesan cheese for a crunchy topping.
* **Make it gluten-free:** Ensure all ingredients are gluten-free. Many sausages are gluten-free, but it’s always best to check the label.
* **Make it dairy-free:** Substitute the milk with almond milk or another plant-based milk. Use dairy-free cheese or omit the cheese altogether.
* **Spice it up:** Add a pinch of cayenne pepper or a dash of hot sauce to the egg custard for a spicy kick.
* **Sweeten it slightly:** Add a tablespoon of maple syrup or brown sugar to the egg custard for a hint of sweetness.
* **Make mini casseroles:** Bake the casserole in individual ramekins for a fun and elegant presentation.
