- Total Time: 1 hour 10 minutes
- Yield: 8 servings
Ingredients
3 cups cooked diced turkey (or rotisserie chicken)
2 cups diced ham
2 cups green beans, trimmed and cut (fresh or frozen)
1 cup diced carrots
1 small yellow onion, diced
2 celery ribs, diced
3 cloves garlic, minced
4 tablespoons unsalted butter
1/4 cup all-purpose flour
1 1/2 cups low-sodium chicken broth
1 cup whole milk
1/2 cup sour cream
1 teaspoon Dijon mustard
1 teaspoon dried thyme
1/2 teaspoon dried rosemary
1/2 teaspoon poultry seasoning
1/2 teaspoon black pepper
1 teaspoon kosher salt (or to taste)
1 cup shredded mozzarella or fontina
1 cup shredded sharp cheddar
4 cups prepared herbed stuffing cubes (boxed or homemade), moistened with 1/2 cup broth + 2 tablespoons melted butter
1/2 cup dried cranberries (optional, festive)
1/2 cup chopped pecans (optional, crunchy topping)
2 tablespoons chopped fresh parsley, for garnish
Instructions
1. Heat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2. Make the creamy base: In a large skillet, melt butter over medium heat. Sauté onion, celery, and carrots until tender, 5–6 minutes. Stir in garlic for 30 seconds. Sprinkle flour over vegetables; cook 1 minute, stirring.
3. Slowly whisk in chicken broth and milk. Simmer, stirring, until thickened and glossy, 3–4 minutes. Off heat, whisk in sour cream and Dijon; season with thyme, rosemary, poultry seasoning, pepper, and salt.
4. Fold in turkey, ham, green beans, mozzarella, and cranberries (if using). Transfer mixture to the prepared dish and smooth the top.
5. Top with cheddar. In a bowl, combine stuffing cubes with melted butter and broth to lightly moisten. Scatter stuffing evenly over the casserole; sprinkle with pecans if using.
6. Bake 35–45 minutes, until bubbling at the edges and the stuffing is deeply golden. Tent with foil if the top browns too quickly.
7. Rest 10 minutes to set. Garnish with parsley and serve warm.
8. Make-ahead option: Assemble fully, cool, cover tightly, and refrigerate up to 48 hours or freeze up to 3 months. If baking cold, add 10–15 minutes; if baking from frozen, cover with foil and add 25–35 minutes, removing foil to crisp the top at the end.
Notes
This casserole is highly customizable: swap turkey for chicken, or use leftover stuffing.
Fontina adds melty richness, while sharp cheddar gives bold flavor contrast.
Dried cranberries and pecans add texture and holiday flair.

Why You’ll Love This Make-Ahead “Christmas Combo” Casserole
A Stress-Free Holiday Morning Solution
The holidays are hectic enough without having to worry about preparing a special breakfast while juggling everything else. This Make-Ahead “Christmas Combo” Casserole is the answer to your Christmas morning prayers. I created this recipe after one particularly chaotic Christmas when I missed watching my daughter open her big gift because I was flipping pancakes in the kitchen.
The beauty of this dish is in its simplicity. You assemble everything the night before—layers of buttery brioche bread, cranberry-orange compote, a cinnamon-spiced egg mixture, and a crumbly streusel topping. Cover it, refrigerate overnight, and in the morning, all you need to do is pop it in the oven. While the casserole bakes, the magical transformation happens: the bread soaks up the custard, the cranberries release their tangy sweetness, and the streusel forms a crispy, caramelized topping that’s absolutely irresistible.
Perfect Balance of Festive Flavors
What makes this casserole truly special is how it captures the essence of Christmas in every bite. The combination of tart cranberries, bright orange zest, warm cinnamon, and rich vanilla creates a symphony of flavors that dance on your palate.
The bread layer provides a custard-like base that’s both comforting and indulgent—not too sweet and not too heavy. The cranberry layer offers a perfect tart contrast that cuts through the richness. And that streusel topping? It adds the most satisfying crunch along with notes of brown sugar and warm spices.
I’ve tested this recipe countless times, adjusting the proportions until reaching the perfect balance where no single flavor overpowers another. My neighbor Mrs. Wilson, who claims to hate cranberries, requested the recipe after trying it at our holiday brunch last year. That’s when I knew this casserole was truly special—it can convert even the most stubborn taste preferences!
Essential Tips & Tricks
Choosing the Right Bread for Perfect Texture
The foundation of any great breakfast casserole is the bread, and for this Make-Ahead “Christmas Combo” Casserole, the choice is crucial. After numerous experiments (and some memorable failures!), I’ve found that brioche or challah bread yields the best results. These enriched breads have a higher egg and butter content, which helps them absorb the custard without becoming soggy.
For optimal texture, use bread that’s slightly stale—about 1-2 days old. If you only have fresh bread, don’t worry! Simply cube it and spread it on a baking sheet for about 30 minutes at 200°F to dry it out slightly. This extra step prevents the dreaded sogginess that can plague breakfast casseroles.
The size of your bread cubes matters too. I recommend cutting them into 1-inch pieces—small enough to soak up the custard but large enough to maintain some structure. If you’re feeling adventurous, you could even try my Eggnog French Toast Casserole bread preparation method, which creates the perfect balance between crisp edges and custardy centers.
Mastering the Make-Ahead Method
The magic of this casserole lies in the overnight rest, which isn’t just for convenience—it’s essential for flavor development. As the casserole sits in the refrigerator, the bread slowly absorbs the egg mixture, allowing the spices to permeate every bite.
For best results, prepare the casserole at least 8 hours before baking, but no more than 24 hours. I’ve found the sweet spot to be about 12 hours. When assembling, make sure to press the bread gently into the custard mixture to ensure even soaking.
The morning of baking, take the casserole out of the refrigerator about 30 minutes before it goes into the oven. This allows it to come to room temperature, which promotes even baking. If you’re in a rush (as we often are on Christmas morning), you can put it directly in the oven from the fridge, but add about 10-15 minutes to the baking time.
For a perfectly baked casserole, cover it with foil for the first 30 minutes of baking, then remove the foil to allow the top to get golden and crispy. This technique prevents the streusel from burning while ensuring the center is fully cooked.
Serving Ideas & Creative Variations
Festive Toppings to Elevate Your Casserole
Once your Make-Ahead “Christmas Combo” Casserole emerges from the oven, golden and fragrant, it’s time to think about how to serve it. While it’s absolutely delicious on its own, a few thoughtfully chosen toppings can take it to the next level.
My family’s favorite is a simple orange-infused maple syrup. Just warm 1 cup of pure maple syrup with the zest of one orange and a cinnamon stick. Let it steep for 10 minutes, then strain and serve in a pretty pitcher alongside the casserole. The warm syrup adds a luxurious touch that complements the cranberry flavors beautifully.
For a show-stopping presentation, try a dollop of vanilla bean whipped cream and a sprinkle of sugared cranberries. The contrast of the cold cream against the warm casserole creates a delightful temperature play, while the sugared cranberries add sparkle and an extra burst of flavor. This combination reminds me of the Fluffy Gingerbread Pancakes I make, where the toppings are almost as important as the base recipe.
A simple dusting of powdered sugar just before serving adds a snow-like effect that’s perfect for Christmas morning. For an adults-only brunch, consider serving with a cranberry mimosa or a spiced coffee cocktail on the side.
Dietary Adaptations Without Compromising Flavor
One of the reasons I love sharing this recipe is how easily it can be adapted for different dietary needs without losing its festive charm. Over the years, I’ve created variations for nearly every dietary restriction, and they’ve all been crowd-pleasers.
For a dairy-free version, substitute the butter with coconut oil and use your favorite plant-based milk in place of dairy milk. The coconut adds a subtle tropical note that pairs surprisingly well with cranberries. For the topping, use coconut oil instead of butter in the streusel.
To make it gluten-free, simply swap in your favorite gluten-free bread. Just be aware that gluten-free breads often absorb liquid differently, so you might need to adjust the amount of custard. I’ve found that adding an extra egg helps bind everything together when using gluten-free bread.
For a lower-sugar option, reduce the sugar in the cranberry layer and use a monk fruit sweetener in the custard. The natural tartness of cranberries means you’ll still get plenty of flavor complexity without all the sugar. This approach works beautifully with my Orange Chocolate Christmas Truffles recipe as well, where reducing sugar actually allows the orange flavor to shine more brightly.
Storage & Troubleshooting Guide
Proper Storage for Leftovers
If you’re fortunate enough to have leftovers of this Make-Ahead “Christmas Combo” Casserole (which rarely happens in my house!), proper storage is key to maintaining its delicious flavor and texture. Once the casserole has cooled completely, cover it tightly with plastic wrap or transfer portions to airtight containers.
Refrigerated leftovers will keep well for up to 3 days. For the best texture when reheating, I recommend individual portions in the microwave for 60-90 seconds. This prevents the edges from drying out while ensuring the center is warmed through. If you prefer using the oven, cover the casserole with foil and heat at 325°F for about 15-20 minutes until warmed through.
For longer storage, this casserole freezes beautifully. Cut cooled leftovers into individual portions, wrap each piece in plastic wrap, then aluminum foil, and freeze for up to 2 months. To reheat from frozen, unwrap, place on a microwave-safe plate, and heat on 50% power for 2-3 minutes, or thaw overnight in the refrigerator and reheat as directed above.
I’ve found that the cranberry flavor actually intensifies slightly after freezing and reheating, which is a lovely bonus!
Troubleshooting Common Issues
Even the most experienced bakers encounter challenges occasionally. Here are solutions to the most common issues you might face with this casserole:
If your casserole turns out too soggy, the most likely culprit is too much liquid or insufficient soaking time. Make sure your bread is slightly dried out before assembling, and don’t exceed the recommended amount of liquid. If it’s already baked and soggy, all is not lost! Simply place it back in the oven uncovered at 325°F for 10-15 minutes to help evaporate excess moisture.
Conversely, if your casserole is too dry, it may have baked too long or the bread may have been too stale. Next time, try reducing the baking time by 5-10 minutes or adding an extra ¼ cup of milk to the custard mixture. For an already-baked dry casserole, drizzling with warm maple syrup or a fruit compote before serving adds moisture and flavor.
If your streusel topping burns before the casserole is fully cooked, cover it with foil for the remainder of the baking time. In future batches, keep the casserole covered for the first 30-35 minutes of baking, then uncover for just the last 10-15 minutes to brown the top.
Remember that oven temperatures vary, so it’s always a good idea to check your casserole about 10 minutes before the recommended baking time is up.
Frequently Asked Questions
Can I make this Make-Ahead “Christmas Combo” Casserole more than one day in advance?
Yes, you can prepare this casserole up to 24 hours in advance. The overnight rest actually improves the flavor as the bread absorbs the custard and spices. I wouldn’t recommend going beyond 24 hours, though, as the bread can become too soggy. If you need to prep further ahead, consider measuring out the dry ingredients and preparing the cranberry layer, then assembling everything the night before baking.
What’s the best way to tell when the casserole is fully cooked?
The casserole is done when the center reaches 160°F on an instant-read thermometer. Visually, the top should be golden brown and slightly puffed, and a knife inserted in the center should come out clean without liquid egg mixture. If the top is browning too quickly but the center isn’t done, cover with foil for the remaining baking time.
Can I use frozen cranberries instead of fresh?
Absolutely! Frozen cranberries work perfectly in this recipe without thawing first. In fact, I often stock up on cranberries during the holiday season and freeze them specifically for this casserole. The cooking time for the cranberry layer may need to be extended by 2-3 minutes if using frozen berries, but otherwise, the recipe remains the same.
How do I prevent the bottom of my casserole from becoming soggy?
To prevent sogginess, make sure your bread is slightly stale or dried out before assembling. Another trick is to sprinkle a thin layer of the streusel mixture on the bottom of the baking dish before adding the bread. This creates a barrier that helps absorb excess moisture. Also, don’t press the bread too firmly into the custard – a gentle press is sufficient.
Can I make this in individual portions instead of one large casserole?
Yes! Individual portions are perfect for a buffet-style breakfast or when serving guests with different dietary preferences. Use ramekins or oven-safe mugs and reduce the baking time to about 25-30 minutes. This approach also works well if you want to freeze portions for quick breakfasts throughout the holiday season. Just follow the same assembly instructions, scaled down to your container size.
