Ingredients You’ll Need

The ingredients for this Crockpot Christmas Breakfast Casserole Recipe are simple, yet each one plays a crucial role in creating the perfect balance of flavors and textures. From the creamy eggs and melty cheeses to the spiced sausage and crispy hash browns, these components work together beautifully to deliver something both hearty and festive.

12 eggs: The rich, protein-packed base that binds all the ingredients together with creamy goodness.
1 cup milk: Adds moisture and helps achieve that light, fluffy texture in the casserole.
2 pounds hash brown potatoes: Provides a satisfying, crispy-yet-soft foundation that soaks up all the delicious flavors.
1 pound bulk breakfast sausage (cooked): Adds savory, spiced depth that’s classic for a holiday breakfast.
½ cup onions (diced): Brings a subtle sweetness and a bit of crunch to the mix.
½ cup bell peppers red & green (diced): Bursts of color and a mild, refreshing bite brighten up every forkful.
1 ½ cups cheddar cheese (shredded from a block): Sharp and melty, it’s the cheesy backbone of this dish.
1 ½ cups pepper jack cheese (shredded from a block): Pepper jack adds a gentle kick and creamy richness for more complexity.
1 teaspoon kosher salt: Enhances all the flavors naturally—use half if using regular table salt.
½ teaspoon black pepper: Offers just the right amount of heat and earthiness without overwhelming the dish.

How to Make Crockpot Christmas Breakfast Casserole Recipe

Step 1: Prepare the Crockpot

Start by spraying the inside of your crockpot with non-stick cooking spray. This simple step prevents the casserole from sticking, making it easier to serve and clean up afterward.

Step 2: Mix the Cheeses

Combine the shredded cheddar and pepper jack cheeses in a bowl. This blend gives you a perfect balance of sharp and spicy flavors that will melt beautifully throughout the casserole.

Step 3: Combine Sausage and Veggies

In a separate bowl, mix the cooked breakfast sausage with the diced onions and bell peppers. This mixture adds layers of both flavor and texture to the dish.

Step 4: Whisk the Eggs

Beat the eggs until fully blended, then whisk in the milk, kosher salt, and black pepper. This custard will soak into each layer, ensuring every bite is rich and flavorful.

Step 5: Layer Your Casserole

Begin by layering one-third of the hash brown potatoes into the bottom of the crockpot. Next, sprinkle on one-third of the sausage and veggie mix. Follow with about 1 cup of the cheese blend. Repeat these layers two more times, finishing with the cheese on top.

Step 6: Pour Egg Mixture and Cook

Pour the egg and milk custard evenly over the layered ingredients. Now, cover the crockpot and cook on low for 8 hours—this slow cooking allows the flavors to meld perfectly and the casserole to set into a dreamy, sliceable delight.

How to Serve Crockpot Christmas Breakfast Casserole Recipe

Garnishes

Once cooked, sprinkle fresh chopped parsley or green onions over the top for a pop of color and freshness. You can also add a dollop of sour cream or a drizzle of salsa for an extra layer of flavor and creaminess.

Side Dishes

This casserole pairs wonderfully with simple sides like fresh fruit salad, warm buttermilk biscuits, or even a light green salad dressed with citrus vinaigrette. The freshness contrasts beautifully with the rich casserole and keeps the meal balanced.

Creative Ways to Present

For a festive twist, serve the casserole in your crockpot right at the table surrounded by holiday decorations or colorful napkins. Alternatively, cut the casserole into individual portions and serve on festive plates with a sprinkle of extra cheese or herbs for a charming buffet-style breakfast spread.

Make Ahead and Storage

Storing Leftovers

Store any leftover Crockpot Christmas Breakfast Casserole Recipe in an airtight container in the refrigerator. It stays fresh for up to 3 days, making it easy to enjoy throughout the holiday weekend without extra cooking.

Freezing

This casserole freezes beautifully if you want to prepare it ahead of time. Wrap tightly in plastic and foil or place in a freezer-safe container. It can be frozen for up to 2 months, so you can savor that festive flavor anytime.

Reheating

To reheat, thaw frozen portions overnight in the fridge or gently warm refrigerated leftovers in the microwave or oven. Warming in the oven at 350°F for 15-20 minutes restores the crispy edges and melty cheese just right.

FAQs

Can I prepare the Crockpot Christmas Breakfast Casserole Recipe the night before?

Absolutely! One of the best parts of this recipe is that you can assemble it the night before, keep it covered in the fridge, and then cook it fresh in the morning. This makes holiday mornings much more relaxing.

Can I use frozen hash browns instead of fresh?

Yes, frozen hash browns work perfectly here. Just be sure to drain any excess moisture before layering, so the casserole doesn’t get watery during cooking.

Is it possible to make this recipe vegetarian?

Definitely! Simply skip the sausage and add extra veggies like mushrooms, spinach, or zucchini to keep the dish hearty and flavorful without meat.

Can I add other types of cheese?

Feel free to experiment with cheeses like mozzarella, gouda, or Swiss. Just remember that a balance of melting and sharpness really makes the casserole shine.

What if I don’t have a crockpot?

If you don’t have a crockpot, you can bake this casserole in a 9×13-inch dish at 350°F for about 45-50 minutes, or until the eggs are set and the cheese is bubbly and golden on top.
