Ingredients

2 tablespoons olive oil, plus more for drizzling

6 medium leeks, (about 2 1/4 pounds), whites and light green parts only, halved lengthwise and thinly sliced crosswise, cleaned

1 teaspoon dried thyme

Coarse salt and freshly ground pepper

4 large slices (1/2 inch thick) hearty country bread

8 ounces Brie cheese, thinly sliced

2 plum tomatoes, thinly sliced crosswise

Preparation

Heat olive oil in a large skillet over medium heat. Add leeks and thyme; season with salt and pepper. Cook, stirring frequently, until leeks are very tender and just beginning to brown, 15 to 20 minutes.

Meanwhile, heat broiler with rack set 4 inches from heat. Arrange bread on a broilerproof baking sheet. Dividing evenly, layer bread with Brie, cooked leeks, and sliced tomatoes; drizzle with olive oil, and season with salt and pepper.

Broil until cheese has melted and tomatoes start to brown, 5 to 8 minutes. Serve immediately.
