One chilly December morning, I decided it was time to try something new for Christmas morning. The kids were buzzing with excitement, and I wanted to make our celebration feel cozy without adding stress. That’s when I found a Christmas Breakfast Casserole recipe that promised comfort with simplicity. I remember feeling a bit nervous—could it really live up to the hype? But as I pulled the golden casserole from the oven, the aroma wrapped around our kitchen like a warm hug. The family gathered around, eyes wide, plates ready, and the smiles said it all. This dish quickly became our holiday go-to because it brought us together, filling bellies and hearts alike.
Christmas Breakfast Casserole turned out to be so much more than just food. It was a comfort bridge between busy mornings and family moments. The sausage and egg casserole flavors combined in a way that felt familiar yet special, which was perfect for the holiday brunch ideas I needed. Since that first morning, I’ve played with the recipe—adding cheese or swapping bread types—to keep it fresh but always comforting. I’ve learned that make ahead breakfast casseroles save my sanity and free me up to enjoy more smiles and less kitchen chaos.
If you’re a fellow busy mom seeking easy Christmas morning recipes that bring calm to the hectic feast preparation, this Christmas Breakfast Casserole will feel like a warm friend. It’s approachable, satisfying, and full of that holiday magic we all crave. Let’s walk through how to get it on your table!
Ingredients You’ll Need:

Here’s where the magic starts for your Christmas Breakfast Casserole. Trust me, the list keeps it simple because comfort needs simplicity!
- 1 pound breakfast sausage (You can swap turkey sausage for a leaner option with no compromise on taste)
- 6 large eggs
- 2 cups shredded cheddar cheese (Feel free to mix in mozzarella for extra melt)
- 4 cups cubed bread (Day-old bread works perfectly — no need for fancy bakery!)
- 1 cup milk (Whole or 2% works fine; even cream adds a richer touch)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 teaspoon dry mustard (Adds a subtle tang—totally optional but a flavor game-changer)
- 1/2 cup diced onions (A quick sauté adds mellow sweetness)
- Optional: chopped bell peppers or mushrooms for a veggie boost
No worries if you don’t have fresh bread – frozen cubes or even croutons have worked wonders in our Christmas Breakfast Casserole experiments. You’ll find all these ingredients at your regular grocery store without breaking the bank, making this holiday breakfast casserole budget-friendly.
Here’s a comfort hack I’ve learned: prepping the sausage and chopping veggies the night before shaves precious minutes off your morning, so you can focus on snuggling with little ones during breakfast.
My family loves the extra comfort when I sprinkle a little extra cheese on top before baking. It melts into golden goodness, making every bite a cozy holiday hug. For more ideas to pair with your casserole, check out my favorite green bean casserole for a dinner side that kids adore.
Let’s Make it Happen!
Ready to dive into your Christmas Breakfast Casserole adventure? Let’s do this together, step-by-step.
- Preheat your oven to 350°F. This is your cozy kitchen starting line.
- Brown the sausage in a skillet over medium heat, breaking it apart as it cooks. Drain excess fat to avoid greasy bites. We love how the sausage adds a hearty, savory element to this holiday breakfast casserole.
- Sauté onions (and any other veggies) in the same skillet until tender. These little flavor builders bring depth to your Christmas Breakfast Casserole.
- In a large bowl, whisk eggs, milk, salt, pepper, and dry mustard. Whisking well ensures each fluffy bite of your casserole is perfectly seasoned.
- Layer the cubed bread, cooked sausage, veggies, and cheese gently in a greased casserole dish. Pour the egg mixture evenly over the layers, pressing down the bread lightly so it soaks up all that goodness.
- Cover with foil and bake for 30 minutes.
- Remove foil and bake another 15 minutes or until the top is golden and puffed. Your Christmas Breakfast Casserole should smell amazing by now—like holiday comfort in every whiff.
If your casserole looks a little wet when you pull it from the oven, don’t worry. It firms up as it cools, and leftover cheese and sausage bring great texture the next day. In my busy kitchen, this Christmas Breakfast Casserole usually takes about an hour total, including prep. Perfect time to prep tomorrow’s lunch or enjoy a peaceful coffee moment while it bakes!
