Ingredients For Christmas Morning Breakfast Casserole
Breakfast sausage: Provides a savory and flavorful base for the casserole.
Eggs: Bind the ingredients together and add richness.
Milk: Adds creaminess and helps to create a custard-like texture.
Salt: Enhances the flavors of the other ingredients.
Black pepper: Adds a hint of spice and depth to the dish.
Shredded cheddar cheese: Melts into the casserole, adding a cheesy flavor.

Technique Tip for This Breakfast Casserole
To enhance the flavor of your breakfast sausage, consider browning it in a skillet with a touch of olive oil before crumbling. This will give the sausage a slightly crispy texture and deepen its savory notes. Additionally, when mixing the eggs and milk, whisk them together vigorously to incorporate air, which will result in a lighter, fluffier texture for your casserole. For an extra layer of flavor, try adding a pinch of nutmeg or cayenne pepper to the mixture.

How to Store or Freeze This Casserole
Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the hash browns soggy.
For short-term storage, cover the baking dish with plastic wrap or transfer the casserole to an airtight container. Store in the refrigerator for up to 3-4 days.
If you're planning to freeze, slice the casserole into individual portions. This makes it easier to reheat only what you need.
Wrap each portion tightly in plastic wrap, then place them in a freezer-safe bag or container. This double-layer protection helps prevent freezer burn.
Label the container with the date and contents. This ensures you remember what deliciousness awaits you and when it was stored.
When ready to enjoy, thaw the casserole in the refrigerator overnight for best results. This gradual thawing helps maintain the texture of the hash browns and cheese.
Reheat in the oven at 350°F (175°C) for about 20 minutes, or until heated through. For a quicker option, use the microwave, but be mindful that the texture might be slightly different.
If reheating from frozen, add an extra 10-15 minutes to the oven time, ensuring the casserole is thoroughly warmed.
For a fresh twist, sprinkle a little extra shredded cheddar cheese on top before reheating to enhance the cheesy goodness.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover casserole in an oven-safe dish, cover it with foil to prevent drying out, and heat for about 20-25 minutes or until it's warmed through. This method ensures the hash browns regain their delightful crispness.
If you're in a hurry, use the microwave. Transfer a portion of the casserole to a microwave-safe plate, cover it with a microwave-safe lid or damp paper towel, and heat on medium power for 2-3 minutes. Check and stir halfway through to ensure even heating.
For a stovetop method, cut the casserole into slices and place them in a non-stick skillet over medium heat. Cover the skillet and let it heat for about 5 minutes, flipping once, until both sides are warmed and slightly crispy.
If you have an air fryer, preheat it to 350°F (175°C). Place slices of the casserole in the basket and heat for 5-7 minutes. This method will give you a crispy top and edges, enhancing the texture of the hash browns.
For a creative twist, transform your leftover casserole into a breakfast burrito. Reheat a portion in the microwave or on the stovetop, then wrap it in a warm tortilla with some fresh salsa and avocado.
