Tip: save now, cook later.This Monte Cristo Croissant Casserole is a wonderful mix of sweet and savory flavors all baked into one cozy dish. It features flaky croissants layered with ham, turkey, and Swiss cheese, then soaked in a custardy egg mixture that bakes until golden and puffed. The hint of powdered sugar and a drizzle of raspberry jam on top add just the right touch of sweetness that makes this casserole stand out.
I love making this casserole for weekend brunch when I want something special but not too fussy. It’s one of those recipes that feels fancy but comes together easily in one dish. I usually prepare it the night before and pop it in the oven in the morning, so I can enjoy the smell of it filling the kitchen while waking up. Plus, the mix of ham and turkey with melted Swiss is always a crowd favorite in my house.
One of my favorite ways to serve this casserole is with a simple green salad or some fresh fruit on the side. The bright, juicy fruit balances the richness of the cheese and eggs perfectly. If you’re feeling extra playful, don’t skip the raspberry jam drizzle or a sprinkle of powdered sugar—it’s a little surprise that everyone loves. It’s a great dish to make when you want something comforting but with a fun twist!
Key Ingredients & Substitutions
Croissants: Fresh croissants work best; their flaky texture soaks up the custard nicely. If croissants aren’t available, buttery brioche or soft sandwich rolls are good alternatives.
Ham & Turkey: I like using deli-sliced ham and turkey for easy layering. You can swap with smoked turkey or cooked bacon if you prefer a smokier flavor.
Swiss Cheese: Swiss melts well and has a mild taste that balances the sweet and savory. Gruyère or provolone can be tasty substitutes.
Egg Custard: Combining eggs, milk, sugar, vanilla, and cinnamon creates the rich custard that soaks the croissants. Whole milk gives creaminess, but you can use half-and-half for even richer results.
Jam & Powdered Sugar: Don’t skip these finishing touches! Raspberry works great, but strawberry or apricot jam are also delightful options to add sweetness.
How Do You Make Sure the Croissants Absorb the Custard Well?
Getting the right soaking time is key to a moist and flavorful casserole without it becoming soggy.
- Layer your croissants and fillings tightly but gently so the custard can penetrate everywhere.
- After pouring the egg mixture, press the top lightly to help the croissants soak up the liquid.
- Let the dish sit for at least 15 minutes at room temperature; longer in the fridge works even better (1-2 hours or overnight).
- If pressed for time, 15 minutes still works, but expect less custard absorption and a lighter texture.
This resting step ensures every bite is custardy and soft inside, with a golden top from baking. Trust me, patience makes a big difference!
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for layering croissants and fillings evenly.
- Mixing bowl – to whisk the egg custard smooth and combined.
- Whisk – helps mix eggs, milk, and spices without lumps.
- Knife – for slicing croissants in half and layering ingredients.
- Measuring cups and spoons – to get your sugar, milk, and spices just right.
Flavor Variations & Add-Ins
- Swap ham and turkey for cooked bacon or sausage for a smokier, heartier flavor.
- Use Gruyère or cheddar cheese in place of Swiss for a sharper cheese taste.
- Add thin apple slices or a sprinkle of dried cranberries inside for a touch of sweetness and texture.
- Mix a pinch of nutmeg into the custard to add warm, cozy spice notes.
Monte Cristo Croissant Casserole
Ingredients You’ll Need:
Main Ingredients:
- 6 large croissants, halved horizontally
- 8 oz sliced deli ham
- 8 oz sliced turkey breast
- 8 oz Swiss cheese, sliced
- 8 large eggs
- 2 cups whole milk
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
- 1/2 teaspoon ground cinnamon (optional)
- Butter, for greasing the baking dish
- Powdered sugar, for dusting
- Raspberry or strawberry jam, for serving
How Much Time Will You Need?
Prep takes about 20 minutes to slice and layer all the ingredients. For the best flavor and custard absorption, plan to let it soak for 15 minutes to 2 hours (or even overnight in the fridge). Baking time is around 35 to 45 minutes until golden and set. So, overall, expect around 1 hour including soaking and baking, or longer if chilling overnight.
Step-by-Step Instructions:
1. Prepare Your Baking Dish and Croissants:
Preheat your oven to 350°F (175°C). Butter a 9×13-inch baking dish well to prevent sticking. Slice each croissant horizontally into halves so you’ll have a top and bottom.
2. Layer Ham, Turkey, and Cheese:
Place half of the croissant bottoms in the dish as a base layer. Over them, evenly layer the sliced ham, turkey, and Swiss cheese. Then top with the remaining croissant halves to form a sandwich-like stack inside the dish.
3. Make the Egg Mixture:
In a large bowl, crack the eggs and add the milk, granulated sugar, vanilla extract, salt, and optional cinnamon. Whisk thoroughly until everything is well combined.
4. Soak the Casserole:
Pour the egg mixture evenly over the layered croissants, pressing gently with a spatula to help the custard soak in. Let the casserole sit for at least 15 minutes to absorb the custard well. For the best texture, cover and refrigerate for 1-2 hours or even overnight if you have time.
5. Bake the Casserole:
Bake uncovered in your preheated oven for 35-45 minutes, or until the custard is set and the top is golden brown and slightly puffed.
6. Add the Finishing Touches and Serve:
Take the casserole out and let it cool slightly. Dust with powdered sugar and serve warm alongside raspberry or strawberry jam—either spread on top or on the side for dipping. Enjoy the delicious sweet and savory flavors!
Can I Use Frozen Croissants for This Casserole?
Yes, you can! Just make sure to thaw them completely before assembling the casserole so they soak up the custard evenly and bake through properly.
Can I Prepare This Casserole the Night Before?
Absolutely! Assemble the casserole, cover it, and refrigerate overnight. This helps the croissants soak up the egg mixture fully and makes morning baking quick and easy.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through.
What Can I Substitute for Swiss Cheese?
Gruyère, provolone, or even mozzarella are great alternatives that melt well and add their own unique flavor to the casserole.
