Delicious and Festive Christmas Breakfast Casserole Recipe

Okay, fellow nutrition-seekers, let me share a little story straight from my kitchen chaos that started my love affair with this Christmas Breakfast Casserole. The first time I tried making it was actually out of pure necessity. Picture this: Christmas morning, kids buzzing around, and me wanting a hearty, nourishing breakfast that wouldn’t have me glued to the stove. I had heard buzz about this Christmas breakfast casserole that could be prepped the night before, so I gave it a shot. My family’s reaction? Pure delight with some impressed “Wow, this is healthy and tasty!” whispers around the table.

What truly made this Christmas Breakfast Casserole a nutrition win was how it quietly packed in veggies and proteins without the kids even noticing. I swapped out the usual heavy sour cream for Greek yogurt, adding a good dose of calcium and protein, which is a big win for growing kids. I had finally found a hearty way to fuel my family that morning without the stress of multiple pots and pans.

This dish became an anchor in my family’s holiday routine, supporting their energy for all the crazy festive play and late-night fun. Honestly, it was a lifesaver in my wellness journey—balanced meals that didn’t feel like a chore! And if you’re a busy mom looking for simple nutrition hacks to keep your family fueled without overwhelm, hang tight. I’m sharing all my best tips on this Christmas Breakfast Casserole, so you’ll have a delicious, nourishing dish ready to go with minimal morning fuss.

If you want to see how I keep this recipe fresh and family-approved, stick around! There’s even a nourishing twist inspired by a great recipe I found over at Lil’ Luna’s Christmas Breakfast Casserole {Make Ahead!} that helped inspire my own version. Because, honestly, what busy mom has time to reinvent the wheel every year?

INGREDIENTS You’ll Need:

Ingredients for Christmas Breakfast Casserole including eggs, cheese, milk, bread, sausage, onion, spinach, and seasonings
  • 8 large eggs – the protein powerhouse of this Christmas Breakfast Casserole.
  • 2 cups shredded cheese (I love sharp cheddar but mozzarella works too) – calcium-rich and melts into gooey goodness.
  • 1 cup milk (I use 2% or almond milk for a dairy-free option) – helps keep this casserole creamy without heaviness.
  • 4 cups cubed whole-grain bread – packed with fiber to keep everyone full longer.
  • 1 pound breakfast sausage or diced ham – you can swap for cooked turkey sausage as a leaner choice.
  • 1 medium onion, diced – adds flavor and nutrients, plus easy digestion help.
  • 2 cups fresh spinach or kale, chopped – more greens never hurt anyone, and this sneaks in iron and vitamins.
  • Salt and pepper to taste.
  • 1/2 teaspoon garlic powder – adds a cozy flavor punch.
  • Optional: 1 cup finely chopped bell peppers – my family loves the color and extra vitamin C.

No worries if you don’t have whole-grain bread on hand—I use sprouted bread sometimes for extra fiber and nutrients in our Christmas Breakfast Casserole. You’ll find all these wholesome ingredients at your local grocery store without hunting specialty aisles. If budgets are tight, swapping sausage for diced ham or skipping bell peppers keeps it affordable but still nutritious.

One mom’s shortcut I swear by: prep your veggies and cubed bread the night before so assembly is a breeze. It’s these easy prep steps that make the whole dish doable on busy mornings.

Trust me, this Christmas Breakfast Casserole ingredient list is simple because busy moms need nutrition without complexity! Plus, my family gets extra nutrition when I add an extra handful of spinach—that hidden green power really adds up over meals!

Let’s Make it Happen!

  1. Preheat your oven to 350°F. This easy breakfast bake warms the kitchen and signals that good things are coming.
  2. Cook your sausage or ham in a skillet until browned and cooked through. Drain any extra fat. Pro tip: If you want leaner protein, swap for turkey sausage here for extra family health points.
  3. In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until everything is blended nicely. This egg mixture is the nutritional glue that holds your Christmas Breakfast Casserole together.
  4. Add the cubed bread, cooked sausage, diced onions, chopped greens, and cheese into the egg mixture. Stir gently until everything is combined. Don’t worry if it looks a little soggy—that’s what makes it so soft and comforting once baked.
  5. Pour the mixture into a greased 9×13 baking dish. Spread it evenly for consistent cooking. This Christmas morning casserole really rewards a gentle touch here.
  6. Let it sit for about 10 minutes if you can, so the bread soaks up the egg mixture. Use this perfect time to prep your kids’ lunchboxes or sip a cup of coffee!
  7. Bake for 45-50 minutes, or until the top is golden and a knife inserted in the center comes out clean. Your kitchen will smell like festive comfort — that’s your nutrition win in progress.
  8. If you want to, broil for an extra 2-3 minutes to get a crispy top. But don’t worry if your Christmas Breakfast Casserole isn’t super crispy—that soft, cheesy texture is pretty much a family favorite here.
  9. Let it cool slightly before slicing. Your Christmas Breakfast Casserole is best served warm but still holds together nicely for leftovers.

In my busy kitchen, this nutritious Christmas Breakfast Casserole usually takes under an hour from start to finish, and the leftovers make morning routines so much easier. Plus, while it cooks, I prep sides or chill drinks, keeping the breakfast chaos under control.

How We Love to Eat This!

Leftovers? Yes, always! We reheat slices gently in the microwave or oven, and they still taste amazing. Nutritionally, they hold up well—it’s a true make-ahead breakfast casserole winner for busy school mornings.
