What elevates the Croque Monsieur above ordinary ham and cheese sandwiches? It’s not just the gourmet cheeses (though those certainly contribute), but the creamy layer of house-made béchamel sauce that coats the bread. As the cheese melts into the sauce, it binds the bread and cheese together, creating a creamy, pillowy texture that makes every bite incredibly moist and indulgent.
The good news? You don’t need to visit a restaurant or buy a whole block of Gruyère cheese to enjoy this French classic at home. Here’s a budget-friendly recipe that requires no skill and can be whipped up in minutes. Get ready to elevate your everyday ham and cheese sandwich and treat yourself to a taste of French comfort food!

ingredients
Bechamel Sauce (Variation):
- ¼ cup half-and-half (or whole milk)
- ½ Tbsp all-purpose flour
- ½ Tbsp unsalted butter

- Pinch of salt
- Freshly ground black pepper

directions

Microwave Bechamel Sauce
In a microwave-safe bowl, whisk together all Bechamel sauce ingredients except the butter until smooth and free of lumps. Add the butter and microwave for 30 seconds (adjust for room-temperature butter). Remove the bowl, stir thoroughly, then return to the microwave and cook for another 20-30 seconds. Stir vigorously until the sauce reaches a smooth and creamy consistency.
Note: While this microwave method works well for small amounts of sauce, using the stovetop is recommended for larger amounts to achieve optimal results.

Assembly
Choose bread that can withstand the creamy bechamel and cheese filling without being hard or crunchy. White country bread is ideal, but firm brioche or sourdough work well too.
Lay two slices of bread on a flat surface. Spread a generous layer of béchamel sauce on one slice, ensuring it covers the entire surface. Top with ham slices and a generous amount of the cheese blend. Finally, cover the sandwich with the remaining bread slice and spread another thick layer of béchamel sauce on top, followed by another generous sprinkle of cheese.
Bake & Serve
Preheat the toaster oven to 400°F (205°C). Place the assembled sandwich on the upper rack and bake for 6-8 minutes, until golden brown and the cheese is melted. For extra browning on top, broil on high for an additional 1-2 minutes. Cut the sandwich in half and serve immediately while hot.

For croque madame
Prepare a fried egg while the sandwich bakes in the oven. Once the Croque Monsieur is golden brown and the cheese is melted, simply place the fried egg on top and serve immediately.
