Step-by-Step Instructions

Step 1: Preheat and Prepare Your Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray. A well-greased dish ensures that your Christmas breakfast casserole doesn’t stick and allows the edges to crisp beautifully.

Step 2: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until well combined. The egg mixture is the foundation of the casserole, so whisk thoroughly to ensure a uniform texture and flavor.

Step 3: Layer the Hashbrowns
Evenly spread the thawed hashbrowns across the bottom of the prepared baking dish. Press them lightly to create an even layer. This layer acts as a hearty base that crisps at the edges while remaining tender in the center.

Step 4: Add the Protein and Vegetables
Scatter the cooked sausage (or your chosen protein) over the hashbrowns. Next, evenly distribute any optional vegetables such as bell peppers, onions, or greens. Layering the vegetables ensures each bite has a balance of flavors and textures.

Step 5: Add the Cheese
Sprinkle cheddar, mozzarella, and Parmesan evenly over the layered hashbrowns, meats, and vegetables. Cheese is critical for binding the casserole and adding a rich, gooey texture that melts into every layer.

Step 6: Pour the Egg Mixture
Slowly pour the egg mixture over the layers, ensuring it seeps through evenly. Gently shake the dish to allow the eggs to settle and fill in gaps. This step ensures that the casserole sets evenly and every layer is coated with the custard-like eggs.

Step 7: Bake
Place the casserole in the preheated oven and bake for 50 minutes, or until the eggs are fully set, the top is golden brown, and the edges are crisp. To test, insert a knife into the center if it comes out clean, the casserole is ready.

Step 8: Rest Before Serving
Allow the casserole to rest for 5-10 minutes before slicing. Resting helps the layers set, making it easier to cut neat portions and enhancing the flavor as the residual heat continues to meld the ingredients.
How to Serve
Serving a Christmas breakfast casserole is all about presentation, balance, and pairing it with complementary sides to create a festive holiday meal. Slice the casserole into generous portions and place them on warm plates to keep them inviting. For a classic holiday table, pair the casserole with lightly dressed fresh fruit, such as orange segments, grapes, or berries, to add a refreshing contrast to the rich, savory flavors. You can also serve it alongside a green salad or roasted winter vegetables for a more balanced brunch, or offer warm muffins, croissants, or a crusty baguette to round out the meal.

To elevate your casserole for a special Christmas brunch, consider small garnishes and sauces that enhance both flavor and visual appeal. A sprinkle of fresh herbs like parsley, chives, or dill adds a pop of color and a fresh aroma. Drizzle with hot sauce, hollandaise, or a tangy tomato chutney for those who enjoy a flavor boost. Serve alongside freshly brewed coffee, hot cocoa, or spiced tea to complete the cozy holiday experience. By thoughtfully pairing sides and garnishes, your Christmas breakfast casserole can shine as the centerpiece of a festive, memorable, and visually stunning holiday table.
