Makes 8

INGREDIENTS

1 package frozen puff pastry, thawed
3 tablespoons butter
1 small leek (white and light green only), cut into 2″ strips
2 cups mixed mushrooms, chopped or sliced (depending on mushroom)
1 teaspoon salt
1 teaspoon black pepper
¼ cup fresh thyme leaves
¼ cup crème fraiche
1 teaspoon lemon zest
¼ cup gruyere cheese
Salt and pepper

DIRECTIONS

Remove one sheet of puff pastry, and cut into 8 equal squares. Using a pairing knife, draw a small frame around each box to create a border (this area will puff and rise as a result of the division). Place on a baking sheet, and chill until ready to use.

In a large sauté pan over medium heat, add butter. Cook leeks and mushrooms, stirring constantly, 5 to 7 minutes. Add salt, pepper, thyme leaves, and continue to cook, 1 to 2 more minutes. Transfer mixture to a lined baking sheet, and let cool.

In a separate bowl, combine crème fraiche, lemon zest, and gruyere cheese, and season with salt and pepper.

Remove puff pastry from refrigerator, and spoon crème fraiche cheese mixture on inside square. Evenly arrange cooled mushrooms and leeks on top of that. Bake for 10 to 15 minutes or until golden and puffed. Serve warm or at room temperature.
