Gratin de Haricots Verts

This delicious French dish features tender haricots verts (French green beans) baked in a creamy cheese sauce.

Ingredients - Serves 6

Preheat the oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Add the haricots verts and cook for 3-4 minutes, until crisp-tender. Drain and set aside.
In a saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute.
Gradually whisk in the milk and cook until the sauce thickens, about 3-4 minutes.
Remove the saucepan from heat and stir in the grated Gruyere cheese until melted and smooth. Season with salt and pepper.
Place the cooked haricots verts in a baking dish and pour the cheese sauce over them. Mix well to coat the beans.
In a small bowl, combine the grated Parmesan cheese and breadcrumbs. Sprinkle the mixture evenly over the beans.
Bake in the preheated oven for 20-25 minutes, until the top is golden and bubbly.
Serve hot as a side dish.
