Equipment

  • skillet
  • baking sheet
  • parchment paper
  • knife
  • spatula or spoon
  • oven

Ingredients

  • 1 tbsp olive oil
  • 2 medium onions, thinly sliced
  • 1 tsp brown sugar
  • 1 tsp balsamic vinegar
  • 1 sheet puff pastry, thawed
  • 4 oz goat cheese, softened
  • 1 egg, beaten (for egg wash)
  • 1 tsp fresh thyme leaves
  • 1 salt and black pepper, to taste

Instructions

  • Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
  • Heat olive oil in a skillet over medium heat. Add sliced onions and cook slowly for 20–25 minutes, stirring occasionally, until golden brown and caramelized.
  • Stir in brown sugar and balsamic vinegar, then cook for 2 more minutes. Remove from heat and let cool slightly.
  • Roll out puff pastry and cut into 6 equal squares or circles. Place on prepared baking sheet and lightly score a 1 cm border around each tartlet.
  • Spread a small spoonful of goat cheese in the center of each pastry square, keeping inside the border. Top with caramelized onions and sprinkle with thyme, salt, and pepper.
  • Brush pastry edges with beaten egg. Bake for 18–20 minutes, until puffed and golden.
  • Serve warm or at room temperature, optionally drizzled with balsamic glaze.

Notes

Caramelize onions slowly for the best flavor — patience pays off. You can prepare the filling in advance and assemble the tartlets just before baking. Serve warm or at room temperature. Add a drizzle of balsamic glaze for extra depth.
