2 ½ tablespoons butter
¼ cup all-purpose flour
1 ¼ cups milk
Pinch of salt
Pinch of ground nutmeg
Instructions
- Melt butter in a small saucepan. Whisk in flour to form a roux.
- Gradually whisk in milk. Cook until thick and smooth. Season with salt and nutmeg. Set aside.
- Preheat oven to 400°F (200°C).
- Place 4 bread slices on a baking sheet. Sprinkle half the grated gruyère on top.

- Sprinkle remaining gruyère over the béchamel.
- Bake for 10–12 minutes, until golden and bubbly.

Notes
Top with a fried or poached egg to make Croque Madame.
Swap gruyère for comté or Emmental cheese for variety.
Lightly toast bread before assembling if you prefer extra crispiness.
Best eaten fresh, but leftovers can be reheated in the oven.
