Ingredients
- 1 sheet puff pastry, thawed

- 2 tbsp olive oil
- 1 tbsp butter
- 1 tsp sugar
- 1 tsp balsamic vinegar
- 4 oz goat cheese, crumbled
- 1 tsp fresh thyme leaves
- Salt and pepper to taste
Instructions
- Step 1: Preheat your oven to 400°F (200°C) to prepare for baking the tarts.
- Step 2: In a pan over medium heat, warm the olive oil and butter together. Add the sliced onions, sugar, salt, and pepper. Cook slowly, stirring occasionally, until the onions are deeply caramelized and golden brown, about 20 minutes.
- Step 3: Stir in the balsamic vinegar and fresh thyme leaves, then remove the pan from heat. Roll out the puff pastry sheet on a lightly floured surface and cut it into squares.

Tips & Variations
- For added crunch, sprinkle chopped walnuts or toasted pine nuts on top before baking.
- Use red onions for a sweeter, milder flavor in the caramelized onions.
- Swap goat cheese for feta or ricotta if you prefer a different cheese texture.
- To make mini tarts, cut the puff pastry into smaller squares for bite-sized treats.
Storage
Store any leftover tarts in an airtight container in the refrigerator for up to 2 days. Reheat them in a preheated oven at 350°F (175°C) for 5-7 minutes to restore crispness before serving.
