Endive and Caramelized Onion Tartlets

Ingredients

• Puff pastry (1 sheet, thawed)
• Butter (2 tablespoons)
• Onion (1 large, thinly sliced)
• Brown sugar (1 tablespoon)
• Balsamic vinegar (1 tablespoon)
• Endive (2 heads, sliced)
• Goat cheese (4 ounces, crumbled)
• Fresh thyme (1 tablespoon, chopped)
• Salt (to taste)
• Pepper (to taste)

Instructions

1. Preheat the oven to 400°F (200°C).
2. Roll out the puff pastry sheet on a lightly floured surface and cut it into 6 equal squares.
3. Place the pastry squares on a baking sheet lined with parchment paper.
4. In a large skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, until they are caramelized, about 15 minutes.
5. Stir in the brown sugar and balsamic vinegar, cooking for an additional 2 minutes until well combined. Remove from heat and let the mixture cool slightly.
6. Divide the caramelized onions evenly among the puff pastry squares, spreading them out in the center.
7. Top each tartlet with a layer of sliced endive, followed by crumbled goat cheese and a sprinkle of chopped thyme.
8. Season with salt and pepper to taste.
9. Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and the toppings are slightly caramelized.
10. Remove from the oven and let the tartlets cool for a few minutes before serving warm.
