Tart with leeks and smoked gouda

Ingredients:

• 1 sheet frozen puff pastry, thawed
• 2 small leeks (white and light green parts only), washed thoroughly, dried and thinly sliced ​​(about 2 1/2 cups)
• 0.5 cup smoked Gouda, coarsely grated
• 1/4 cup grated Parmesan (on the finest grater)
• 2 tbsp finely chopped chives
• Flour, for dusting

Preparation:

1. Preheat oven to 200°C. On a lightly floured surface, roll out the puff pastry into a 32 x 25 cm rectangle and transfer to a parchment-lined baking sheet. Prick the dough with a fork and sprinkle with the leeks and all the cheese. Season with a pinch of salt and 1/4 teaspoon of black pepper.
2. Bake until the crust is deep golden and the leeks are tender, 25 to 30 minutes. Let cool for 10 minutes. Sprinkle with chopped green onions, cut the tart into 16 or 24 wedges, and serve.
