Growing up, I had an insatiable curiosity about food. My kitchen adventures began with childhood memories of gooey grilled cheese sandwiches, the kind that left little fingerprints on the corners of my mom’s kitchen counter. Fast forward a few decades, and my obsession with sandwiches evolved. Enter the Croque Monsieur: a luxurious twist on a classic.
This delightfully cheesy, ham-filled creation originates from France. Picture layers of crispy bread seductively cloaked in a luscious béchamel sauce. Every bite transports you to a quaint Parisian café. Martha Stewart, the goddess of home cooking, has a recipe that embodies this delightful treat. So, grab your apron, and let’s bring a little French flair into your kitchen!

What Is Martha Stewart’s Croque Monsieur?
Martha Stewart’s Croque Monsieur recipe elevates the humble sandwich to a level fit for royalty. It features thick slices of brioche bread toasted to golden perfection, paired with savory baked ham, and crowned with a decadent smooth cheese sauce.

What Is the Flavor Profile of This Dish?
The Croque Monsieur explodes with contrasting flavors and textures. Picture the sweetness of toasted brioche: it’s crunchy on the outside while staying soft inside, creating a foundation for the dish. The ham adds a savory depth to each bite, enhanced by the nutty, earthy tones of Gruyère cheese.
The béchamel sauce? It’s where the real magic happens. Smooth, creamy, and slightly nutty, it brings everything together nicely. A hint of Dijon mustard interjects a subtle tang, and a dash of freshly grated nutmeg ties the whole flavor profile together, wrapping everything in warmth.

Ingredients
Let’s gather our ingredients to create this masterpiece. Here’s what you’ll need:
- 8 slices brioche, cut into ½-inch thick pieces and lightly toasted
- 6 ounces of thinly sliced baked ham
- 3 tablespoons unsalted butter, plus extra for greasing the baking sheet
- ¼ cup all-purpose flour
- 2 cups whole milk
- 1 cup Gruyère or Swiss cheese, shredded, plus 8 ounces, paper-thin slices
- Coarse sea salt
- Freshly ground white pepper
- A dash of freshly grated nutmeg
- 1 tablespoon Dijon mustard
- ½ cup sautéed shallots

Step by Step Instructions
Step 1: Preheat Your Oven
Start by preheating your oven to 400°F (200°C). The warmth will create a cozy environment for your Croque Monsieur to bake and develop that beautiful golden crust.
Step 2: Prepare the Béchamel Sauce
In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once the butter is frothy, whisk in the flour. Cook this mixture for about 2-3 minutes until it forms a paste. This is known as a roux and is the base for your béchamel sauce. Gradually pour in the milk while whisking continuously to avoid lumps. Keep whisking until the mixture thickens—about 5-7 minutes.
Once thickened, stir in the shredded Gruyère cheese. Season with a pinch of salt, freshly ground white pepper, and a dash of nutmeg, followed by the tablespoon of Dijon mustard. That’s your luscious béchamel ready to take the lead!
Step 3: Assemble the Sandwiches
Grease a baking sheet with a bit of butter. Lay four slices of toasted brioche on the sheet. Top each slice with a generous layer of ham, followed by a slice of Gruyère cheese. Spread a little of the béchamel sauce on top of the cheese, making sure it’s all covered. Place the remaining slices of brioche on top to create a sandwich.
Step 4: Add more Sauce and Cheese
Pour the remaining béchamel sauce over each sandwich, ensuring they are all generously drenched. Sprinkle the remaining Gruyère cheese on top. Feel free to add extra cheese—because more cheese is always better!
Step 5: Bake to Perfection
Bake the sandwiches for about 15-20 minutes in your preheated oven, or until the tops are bubbling and golden brown. Keep an eye on them to prevent burning.
Step 6: Let Rest and Serve
Once done, let them cool slightly. This resting time allows the gooeyness to settle. Cut each sandwich in half, serve hot, and watch your family swoon.
Tips & Tricks
Here are five handy tips to ensure your Croque Monsieur is absolutely stellar:
- Use Day-Old Bread: Stale bread holds up better when grilled or baked. It prevents sogginess.
- Experiment with Cheeses: Mix Gruyère with some sharp cheddar for an extra punch.
- Take Your Time with the Sauce: Don’t rush your béchamel sauce. A slow approach makes it smoother.
- Try Different Meats: Substitute ham with turkey or chicken. Or amp up the flavor with prosciutto!
- Watch the Oven: Ovens vary. Check for golden-brown perfection a bit early to avoid overcooking.
How Can You Store This Martha Stewart Croque Monsieur Recipe?
If you have leftovers, you’re in luck. The Croque Monsieur can be stored in the refrigerator. Place the cooled sandwiches in an airtight container for up to three days.
To reheat, pop in the oven at 350°F until heated through, about 10–15 minutes, to maintain that crispy texture.
If Some Ingredients Are Not Available, What Are Some Alternative Choices You Can Consider?
No worries if you find yourself lacking some ingredients. Here are a few substitutions to consider:
- Bread: Challah or Sourdough – Both options will hold up nicely and add unique flavors.
- Cheese: Mozzarella or Fontina – These can give a pleasant stretch while still being delightful.
- Milk: Almond or Oat Milk – For a dairy-free option, these alternatives can work. Just go for unsweetened varieties.
