Now, let’s explore the ingredients you’ll need to create this festive masterpiece!
Ingredients:
- 1 lb bulk Italian sausage
- 1 cup chopped onion
- 1 (7-ounce) jar roasted red peppers, drained and chopped, divided
- 1 (10-ounce) package frozen chopped spinach, thawed and well drained
- 1 cup flour
- 1/4 cup grated Parmesan cheese
- 1 teaspoon dried basil
- 1/2 teaspoon salt
- 8 eggs
- 2 cups milk
- 1 cup shredded provolone cheese
Before you get started, there are a few things to reflect on about the ingredients. For instance, the Italian sausage adds a savory kick, but if you prefer a milder flavor, you could always switch it out for turkey sausage or even a veggie option.
And don’t stress if you can’t find roasted red peppers – you can easily roast your own or substitute with fresh bell peppers for a different twist.
Also, remember to squeeze out as much moisture as possible from the spinach so your casserole doesn’t end up soggy. Trust me, no one wants a watery breakfast!
Finally, feel free to get creative; you can add in some extra spices or even throw in your favorite cheese to personalize it to your family’s taste. After all, it’s all about making this dish your own, right?
How to Make Christmas Breakfast Casserole

Making the Christmas Breakfast Casserole is easier than you might think, and it’s a dish that practically makes the holiday morning merrier. Let’s kick things off by cooking 1 pound of bulk Italian sausage and 1 cup of chopped onion in a skillet over medium heat. You want to cook this until the sausage is no longer pink, which usually takes about 5 to 7 minutes. Keep an eye on it, though; you don’t want to burn the onions or let the sausage turn into tiny little rocks.
Once it’s cooked, drain any excess grease—and yes, I promise, that’s the last of the heavy lifting you’ll have to do for a while. Transfer this savory mixture to a greased 3-quart baking dish, and sprinkle half of a 7-ounce jar of chopped roasted red peppers and the entire 10-ounce package of well-drained, thawed spinach over the top. Can you smell the goodness already?
Now comes the fun part. In a separate mixing bowl, grab 1 cup of flour, 1/4 cup of grated Parmesan cheese, 1 teaspoon of dried basil, and 1/2 teaspoon of salt. Mix those dry ingredients together like you’re building a snowman—just a gentle blend will do.
In another bowl, crack 8 eggs and combine them with 2 cups of milk. Whisk it all together until it’s smooth like your favorite holiday playlist. Pour this eggy mixture over the spinach and sausage layer in the baking dish, making sure it gets into all the nooks and crannies. Trust me, you want every bite to be packed with flavor.
Bake the casserole at 425°F for 20 to 25 minutes. Keep your eye on it; you’re looking for a clean knife when you insert it near the center. Once that’s done, sprinkle 1 cup of shredded provolone cheese and the remaining roasted red peppers on top, then pop it back in the oven for just 2 more minutes, or until the cheese is melted and bubbly.
Let it stand for about 5 minutes before cutting into it. And there you have it—a holiday breakfast that not only tastes like joy but makes the kitchen smell heavenly too. Enjoy every bite, and don’t worry about the clean-up—after all, it’s Christmas!
Christmas Breakfast Casserole Substitutions & Variations
If you’re looking to customize your Christmas Breakfast Casserole, you’ve got plenty of options to suit your taste and dietary needs.
For a vegetarian version, swap the sausage for sautéed mushrooms or a plant-based alternative. You can also change up the cheese; cheddar or feta work well too.
If you’re gluten-free, use a gluten-free flour blend instead. Feel free to add veggies like bell peppers or zucchini for extra flavor and nutrition.
Want a little heat? Toss in some diced jalapeños. The possibilities are endless, making it easy to create a casserole that’s perfect for your holiday brunch!
Additional Tips & Notes
Customizing your Christmas Breakfast Casserole is just the beginning; there are also some handy tips to guarantee it turns out perfectly.
First, make sure to drain the spinach thoroughly to avoid a soggy casserole. If you prefer a crispy top, broil it for a minute or two after baking.
I also recommend letting it sit for about five minutes before cutting—this helps it set and makes serving easier. For extra flavor, consider adding herbs like thyme or rosemary.
Finally, if you have leftovers, store them in the fridge; they make for a delicious breakfast the next day! Enjoy!
