Recipe notes
This bistro sandwich recipe is easy to make at home. Perfect for lunch or a light supper when served with a salad. Top with a fried egg for an upgraded Croque Madame.
RECIPE Preparation
- In a large skillet over medium-high heat, melt 2 tablespoons of black truffle butter. Add mushrooms and thyme, turn to coat; season with salt and pepper. Sauté until mushrooms have released their liquid and are deeply golden brown and slightly dry. Stir in half of the chives. Set aside.
- In a saucepan over medium-high heat, melt remaining 4 tablespoons of truffle butter. Add flour and whisk frequently until mixture turns golden brown and foamy, about 4 minutes. Gradually add milk, whisking constantly until smooth and thickened, about 4 more minutes. Remove from heat and whisk in mustard; season with nutmeg, salt, and pepper, to taste.
- Lay all eight slices of country bread on a sheet pan. Spread each slice with a thick coating of béchamel in an even layer. On four of the slices, top béchamel with the reserved mushroom mixture and half of the cheese. Lay the béchamel-only slices on top and spread the rest of the cheese over the béchamel. Sprinkle with the remaining chives.
- Bake until the cheese is melted and the tops of the sandwiches are golden brown and crusty, about 15-20 minutes. Serve immediately, with cornichons and baby greens dressed with vinaigrette.
