Step 1: Prepare the Filling
Cook the vegetables:
In a large skillet over medium heat, add olive oil and chopped leek. Fry for 10-15 minutes until the leeks are softened and slightly caramelized.
Add the grated carrot and chopped bell peppers to the skillet. Season with salt and black pepper to taste. Stir well and cook until the vegetables are tender.
Prepare the filling mixture:
In a mixing bowl, combine the cooked vegetables, 1 tablespoon tomato paste, and 1 teaspoon red pepper flakes (if using). Mix well.
Add 1 egg white and 200g grated cheese to the mixture. Stir until everything is evenly combined.
Step 2: Assemble the Puff Pastry Tart
Preheat the oven:
Preheat the oven to 160°C (320°F).
Prepare the puff pastry:
On a lightly floured surface, roll out the puff pastry sheets if needed to fit your baking tray.
Lay the first sheet of puff pastry on a baking sheet lined with parchment paper. Spread the filling evenly over the pastry, leaving a small border around the edges.
Top with the second pastry sheet:
Place the second sheet of puff pastry on top of the filling. Press down along the edges to seal the tart.
Brush with egg yolk and add cheese:
Brush the top of the puff pastry with the egg yolk for a golden finish.
Sprinkle additional cheese on top for extra flavor.
Step 3: Bake the Tart
Bake in the preheated oven at 160°C (320°F) for 20 minutes, or until the puff pastry is golden brown and the cheese is melted and bubbly.
Step 4: Serve
Remove from the oven and allow the tart to cool slightly before slicing.
Serve warm as a light meal, appetizer, or side dish.
Serving Suggestions:
