I still remember the first time I realized a Christmas Breakfast Casserole could be both nourishing and delicious without feeling like a big, complicated project. It was a cozy December morning a few years back, and I wanted something warm and filling for my family’s breakfast, but I wasn’t up for the usual piles of greasy sausage or sugary pastries. That’s when I stumbled onto this easy Christmas breakfast recipe that balanced fresh veggies, wholesome eggs, and a touch of comfort—all baked into one festive breakfast bake.
What surprised me most was how this Christmas Breakfast Casserole fit into my real life. No strict rules or fancy ingredients, just a recipe that felt doable even when time was tight. It became a gentle reminder that nourishing food can be part of joyful celebrations, not a source of stress or restriction. Since then, this casserole has become a go-to in our kitchen, especially during the holidays, when we want something hearty and cozy but without a mountain of last-minute prep.
If you’re a fellow home cook looking for a simple, feel-good dish that brings people together around the table, I’m excited to share everything I’ve learned about making this holiday breakfast casserole a family favorite. Trust me—it’s easier than you think, and the taste is worth every bite. Whether you’re new to festive breakfast bakes or looking to add a reliable egg casserole for Christmas to your rotation, this one’s a keeper. Let’s dive in and chat about what you’ll need!
What You’ll Need:
Here’s the ingredient list for this Christmas Breakfast Casserole. I keep it simple because good food doesn’t need to be complicated.
- 8 large eggs — these make the base hearty and nourishing
- 1 cup milk (dairy or plant-based) — for a tender, fluffy bake
- 4 cups cubed bread (day-old or fresh; whole grain or sourdough works beautifully)
- 1 cup diced bell peppers (red or green) — you can find these in the produce aisle year-round
- 1 cup chopped spinach or kale — a fresh vegetable boost that keeps costs low
- 1 cup shredded cheese (cheddar or mozzarella) — no stress if you don’t have this; I sometimes swap for feta or skip it altogether
- 1/2 cup cooked sausage or ham, chopped (optional) — for extra protein, but it’s equally tasty without
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon dried herbs like thyme or oregano (optional)
No worries if you’re missing bell peppers or kale. I often use frozen peas or grab whatever veggies are fresh at my market. For budget-friendly options, this holiday breakfast casserole keeps costs down by leaning on simple eggs and seasonal produce. If your mornings are busy, you can prep some ingredients the night before—like chopping veggies or cooking sausage.
Leftovers? I usually store mine in an airtight container in the fridge and they reheat well for two days, perfect for a simple weekday start.
Let’s Make It Together!
Ready to cook? Let’s make this Christmas Breakfast Casserole side-by-side. In my kitchen, it usually takes about 45 minutes from start to finish, including baking. Perfect timing to set the table or brew some coffee while it does its thing.
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or cooking spray.
- In a big bowl, whisk the 8 large eggs until well combined. Stir in the milk, salt, pepper, and dried herbs until smooth.
- Add the cubed bread into the egg mixture, pressing gently so it soaks up the eggs well. This part makes the casserole wonderfully custardy.
- Fold in the diced peppers, chopped greens, cooked sausage (if using), and cheese. Mix until evenly distributed.
- Transfer the mixture to your prepared baking dish. Spread it out evenly.
- Pop it in the oven for about 35-40 minutes. You’ll know it’s ready when the top is golden, and a knife inserted in the center comes out clean. Your kitchen should smell absolutely inviting by now.
Quick kitchen tip: If you want to save time, you can mix everything the night before and keep it covered in the fridge. When morning comes, just pop it in the oven directly from the fridge—you may need a few extra minutes to bake through.
If your Christmas Breakfast Casserole looks a little wet when you take it out, no worries. Let it sit for 5-10 minutes to firm up before slicing. I used to rush this step and ended up with a floppy bake — patience is key here!
How I Love to Serve This!
This Christmas Breakfast Casserole becomes a complete meal when I pair it with fresh fruit salad or roasted potatoes. The juicy fruit balances the rich egg bake, making it feel special but still easy.
I’ve served this festive breakfast bake for holiday mornings, weekend brunches, and even casual weeknight dinners. It’s flexible and a crowd-pleaser no matter the occasion! Presentation-wise, a sprinkle of fresh herbs (hello, parsley or chives) on top really makes it pop.
Leftovers? I love cubing any leftover casserole and tossing it into a salad or heating it up alongside a quick soup. Seasonal variations are fun to experiment with — pumpkin spice French toast casserole (recipe here) or a cheesy breakfast casserole like this one can add different vibes without much effort.
Family and friends often ask for the recipe after tasting this, which always feels like a win in my book!
Common Questions Answered
I get lots of questions about making a Christmas Breakfast Casserole, so I’m happy to share what I’ve learned.
Can I make this Christmas Breakfast Casserole ahead for meal prep?
Absolutely! I often prepare the entire casserole the night before and refrigerate it covered. In the morning, bake it straight from the fridge, adding a few extra minutes to the bake time. It’s a lifesaver for busy holiday mornings.
What if I don’t have all the ingredients for this Christmas Breakfast Casserole?
No stress at all! This egg casserole for Christmas is super forgiving. Swap out veggies for whatever’s fresh or frozen, use a different cheese, or omit meat for a vegetarian version. The key is to keep the balance of eggs, bread, and flavor.
How can I adjust the flavor of this Christmas Breakfast Casserole to my taste?
Spices and herbs are your best friends. Try adding a pinch of smoked paprika, garlic powder, or fresh herbs like dill or rosemary. Even a drizzle of hot sauce or a dollop of salsa on the side can brighten up flavors.
Can I freeze leftovers of this Christmas Breakfast Casserole?
Yes! Cool completely, then wrap and freeze in portions. Thaw overnight in the fridge and reheat in the oven or microwave. This keeps your meals nourishing and convenient.
What’s the best bread for this holiday breakfast casserole?
Day-old bread works best for soaking up the egg mixture. Whole grain, sourdough, or even a softer white bread can be used depending on your preference and budget.
Do I have to use meat in this egg casserole for Christmas?
Not at all. It’s equally tasty without meat. I often make a veggie-only version for my friends who prefer plant-based meals.
Is there a way to make it lighter or dairy-free?
Using plant-based milk like almond or oat milk and skipping cheese or choosing a dairy-free cheese works great. For a lighter version, go heavier on the veggies and skip the meat and cheese.
Final Thoughts
This Christmas Breakfast Casserole holds a special spot in my kitchen routine because it blends simplicity with something truly satisfying. It’s my go-to when I want a meal that’s easy to prep, feels nourishing, and warmly invites everyone to the table without the stress.
My Favorite Christmas Breakfast Casserole Tips:
- Prep veggies and meat the night before to save morning time
- Use day-old bread for best texture and less waste
- Don’t rush the resting time after baking—it helps the casserole set perfectly
I’ve tried several variations—like swapping bell peppers for mushrooms or using kale instead of spinach. Sometimes I switch meat to turkey sausage or none at all. But the version I return to is the classic mix of eggs, cheese, bread, and a handful of fresh greens.
