Ingredients You Need

This Christmas Breakfast Casserole ingredient list is all about bold flavors that actually work together! Here’s what you’ll want to have on hand for this festive breakfast bake:
- 8 large eggs – the base of our breakfast strata magic
- 2 cups whole milk – for that creamy, dreamy texture
- 1 teaspoon salt – balances all those bold flavors
- 1/2 teaspoon black pepper – adds a gentle kick
- 1 teaspoon smoked paprika – here’s the Christmas Breakfast Casserole secret that takes it from good to incredible
- 1/2 teaspoon garlic powder – perfect for that subtle warmth
- 4 cups cubed day-old bread – hearty bread like sourdough or a French loaf works great
- 2 cups shredded sharp cheddar – for melty, cheesy goodness
- 1/2 pound breakfast sausage, cooked and crumbled – no worries if you don’t have sausage; I often swap it with diced ham or turkey bacon in my Christmas Breakfast Casserole
- 1/2 cup diced bell peppers – colorful and fresh
- 1/2 cup chopped onion – adds that savory depth
- 1 cup fresh baby spinach – a little green never hurts!
You can grab everything during your normal shopping trip without hunting for fancy ingredients. This Christmas Breakfast Casserole gets its amazing taste from layering those flavors in every bite, boosted by smoked paprika and a mix of fresh veggies.
Busy night? Chop veggies in advance or use frozen spinach (thawed and drained!) to speed things up. Store leftovers airtight in the fridge for up to three days, and they taste just as vibrant reheated for a quick breakfast.
I love adding extra sharp cheddar or a sprinkle of red pepper flakes to my Christmas Breakfast Casserole when dinner needs a little extra punch of flavor!
Let’s Make Some!
Alright, fellow food lovers, let’s jump into making this Christmas Breakfast Casserole and turn your kitchen into a cozy flavor hub. Here’s exactly how I make this festive breakfast bake happen, step-by-step!
- Preheat the oven to 350°F. This is where the magic starts happening! Get your favorite casserole dish greased and ready.
- In a large bowl, whisk together eggs, milk, salt, pepper, smoked paprika, and garlic powder. Your Christmas Breakfast Casserole should smell absolutely incredible right now! This mix is your flavor base.
- Add in the cubed bread, cooked sausage, shredded cheddar, diced peppers, onions, and spinach. Toss it gently so everything gets coated with that creamy, spicy egg mixture. Don’t worry if your Christmas Breakfast Casserole looks a little wild or uneven—that’s the charm!
- Let the bread soak for 10 minutes while you get other things ready. In my kitchen, this usually passes quick because the anticipation is real!
- Pour everything carefully into your casserole dish. Try to spread it evenly so every bite gets a bit of everything.
- Bake uncovered for 45-50 minutes. Halfway through, peek in and give it a little jiggle—the casserole should mostly be set but still moist in the middle. This is perfect! Bonus: while your Christmas Breakfast Casserole is doing its thing, get ready for some amazing aromas to fill your home.
- When the top turns golden and is just starting to crisp, take it out and let it rest for 5 minutes. This settling time helps lock in flavors and textures.
From my experiments, this Christmas Breakfast Casserole hits the perfect balance of creamy, cheesy, and savory, all while staying cozy and festive. If you’re short on time, prepping the mix the night before and baking it in the morning works like a charm!
This recipe reminds me of another bold flavor favorite: my Butternut Squash Casserole. Both dishes bring that comfort food vibe with tasteful upgrades!

This Christmas Breakfast Casserole is perfect for those weeknight dinners that need to be special without fuss. It pairs beautifully with a fresh yogurt parfait or even a quick batch of my Croissant Breakfast Sandwiches for when you want something portable and bold to take along.
Presentation wise, sprinkle a little extra sharp cheddar or a dusting of smoked paprika on top after baking to remind everyone this is no ordinary holiday breakfast casserole. Trust me, the colors and flavors pop like fireworks at a festive breakfast bake!
Got leftovers? Stir it into scrambled eggs the next morning or layer it with salsa and extra cheese for a quick spin on breakfast chili – like my favorite Breakfast Chili and Eggs recipe.
I’ve even tried a fusion twist by swapping sausage for spicy chorizo and tossing in some roasted poblano peppers. It’s a flavor adventure that made my friends at game night swoon with every bite!
FAQs:
Will kitchen newbies succeed with this Christmas Breakfast Casserole?
Absolutely! This recipe is forgiving and perfect for any level of cooking skill. It’s all about layering flavors and letting the oven work its magic. If you can whisk eggs and chop veggies, you’re golden!
What if I mess up my Christmas Breakfast Casserole? (Spoiler: it’ll still taste incredible!)
Even if your bread cubes aren’t perfectly soaked or your veggies aren’t evenly spread, the bold flavors and creamy texture carry the dish through. In my testing, one early version was a little dry, so I added extra milk and cheese next time, and wow, it upped the comfort food factor big time.
Can I prep this Christmas Breakfast Casserole for busy weeknights?
Yes! Assemble it the night before, cover it tightly, and pop it into the fridge. In the morning or when you’re ready, just bake it. It’s the perfect easy Christmas morning casserole hack.
What kind of bread works best?
Day-old or slightly stale bread like sourdough or French bread holds up nicely. I tested softer breads too but found they soak up too much liquid — which can get messy!

Totally. Use diced ham, turkey bacon, or your favorite plant-based sausage substitute. I like the mix-and-match options for exciting Christmas brunch recipes.
How do I store leftovers?
Keep them tightly sealed in an airtight container in the fridge for up to three days. Reheat in the microwave or oven for a quick, delicious meal.
