Hello, welcome to my beautiful world! My name is Prisca Bush. I am a food lover; I enjoy writing about my favorite recipes.
Introduction
There are certain dishes that feel like a hug from the inside out—and for me, the Monte Cristo will always be one of them. The first Monte Cristo Croissant Casserole Recipe I ever tried was during a weekend brunch at a tiny café tucked between antique shops. It was indulgent in all the right ways: buttery bread, smoky ham, gooey cheese, and that unexpected touch of sweetness from a dusting of powdered sugar and a side of jam. It was one of those bites that made me pause because it was so good in such a surprising way.
Years later, someone suggested making a Monte Cristo as a casserole instead of sandwiches, and once I tried it, I never went back. Turning this classic into a baked dish not only makes it easier to feed a crowd, but it somehow becomes even more comforting. And using croissants—flaky, buttery, golden croissants—takes it to a whole new level of deliciousness.
This Monte Cristo Croissant Casserole Recipe is exactly the type of thing I love making for brunches, holidays, potlucks, or any morning when I want something decadent but simple to prepare. It’s sweet, savory, cheesy, and satisfying, and the kind of recipe people rave about long after breakfast is over.
Let’s dive into your new favorite brunch dish.

How to Make Monte Cristo Croissant Casserole Recipe (Step-by-Step)
This Monte Cristo Croissant Casserole Recipe is amazingly simple to assemble, which is one of the many reasons it’s perfect for brunch.
1. Prep the Baking Dish
Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Layer the Croissants
Cut each croissant into halves or thirds for better layering.
Arrange about half the croissant pieces in the bottom of the dish, cut side down.
3. Add Ham, Turkey, and Cheese
Layer:
- half the ham
- half the turkey
- half the Swiss cheese
Add another layer of croissants, then the remaining meat and cheese.
TIP: Overlap slices for even coverage and better flavor distribution.
4. Mix the Egg Custard
In a large bowl, whisk together:
- 6 eggs
- milk
- heavy cream
- Dijon mustard
- honey
- salt and pepper
- nutmeg (optional, but adds a warm depth)
Whisk until completely smooth.
5. Pour the Custard Over the Casserole
Slowly pour the mixture evenly over the croissants.
Press the croissants down slightly so they absorb the custard.
6. Rest (Highly Recommended)
For best texture:
- Cover with foil
- Refrigerate for at least 30 minutes, or up to overnight
This helps the croissants fully soak up the custard.
If you’re short on time, you can bake it immediately—just know the texture will be slightly softer.
7. Bake
Preheat the oven to 350°F (175°C).
Bake covered for 30 minutes, then uncover and continue baking for 20–25 minutes, or until:
- the top is golden
- the custard is fully set
- the cheese is bubbling
8. Rest Before Serving
Allow the casserole to rest for 10 minutes so it cuts cleanly and retains structure.

Tips for the Best Monte Cristo Croissant Casserole Recipe
1. Use Sturdy or Slightly Stale Croissants
Fresh croissants are soft and can get mushy.
Day-old croissants hold their shape best.
2. Choose High-Quality Cheese
Swiss or Gruyère melt beautifully and offer rich flavor.
Avoid pre-shredded cheese if possible—it has anti-caking agents that prevent smooth melting.
3. Let It Soak for Better Texture
Refrigerating overnight gives you a luxurious custardy interior.
4. Don’t Skip the Dijon
It adds subtle tanginess and balances the sweetness perfectly.
5. Add Extra Layers
More layers = more flavor with every bite.
6. Adjust Sweetness to Taste
- Add more honey for a sweeter profile
- Skip the powdered sugar if you prefer savory
- Serve jam on the side so guests can choose sweetness level
7. Bake Covered, Then Uncovered
This ensures the interior is cooked without drying out the top.
8. Let It Rest Before Cutting
A 10-minute rest helps everything set and makes serving easier.
