Caramelized Onion Tartlets

Ingredients:

• 4 large onions, thinly sliced
• 2 tablespoons olive oil
• 1 tablespoon butter
• 2 teaspoons balsamic vinegar
• 1 teaspoon sugar
• Salt and pepper, to taste
• 1 sheet of puff pastry (thawed if frozen)
• 1/4 cup grated Parmesan cheese
• Fresh thyme (optional)

Instructions:

1. Caramelize the onions:
   • Heat olive oil and butter in a large pan over medium heat.
   • Add the sliced onions and stir to coat them evenly.
   • Cook the onions for 20-30 minutes, stirring occasionally. Lower the heat if they begin to brown too quickly.
   • Add balsamic vinegar, sugar, salt, and pepper in the last 5 minutes to balance the sweetness and add a rich flavor. Stir and cook until the onions are deeply golden and caramelized. Set aside.
2. Prepare the puff pastry:
   • Preheat the oven to 400°F (200°C).
   • Roll out the puff pastry sheet on a lightly floured surface and cut it into squares or circles, depending on your preference.
   • Place the puff pastry pieces on a lined baking sheet.
3. Assemble the tartlets:
   • Spoon the caramelized onions onto each puff pastry square or circle, leaving a small border around the edges.
   • Sprinkle a little grated Parmesan cheese over the top.
   • Optionally, top with fresh thyme leaves for an herbaceous note.
4. Bake:
   • Bake in the preheated oven for 12-15 minutes, or until the puff pastry is golden and crispy.
5. Serve:
   • Serve warm as an appetizer or alongside a salad. Enjoy the rich, sweet flavor of the caramelized onions!
