Ingredients

Scale

Pastry

  • 1 sheet puff pastry (thawed but still cold)

Caramelized Onions

  • 2 large onions, thinly sliced (yellow or sweet onions)
  • 2 tablespoons olive oil
  • 1 tablespoon butter
  • 1 teaspoon sugar
  • 1 teaspoon balsamic vinegar
  • 1 teaspoon fresh thyme leaves
  • Salt and pepper to taste

Topping

  • 4 oz goat cheese, crumbled (creamy, log-style)
  • Additional fresh thyme leaves for garnish (optional)

Instructions

  1. Caramelize the Onions: Heat olive oil and butter in a large pan over medium heat. Add thinly sliced onions, sugar, salt, and pepper. Cook the onions undisturbed for about 5 minutes between occasional stirs. Continue cooking for about 15 minutes until onions turn golden. Add balsamic vinegar and fresh thyme, then cook for another 5 minutes until the onions become jammy and sweet. If onions stick, add a splash of water to deglaze the pan.
  2. Assemble the Tarts: While onions cool slightly, roll out puff pastry on a lightly floured surface. Cut the pastry into 6 rectangles. Spread caramelized onions evenly over each piece, leaving a small border around the edges. Crumble goat cheese generously over the onions and sprinkle a little extra thyme on top for garnish.
  3. Bake to Perfection: Preheat oven to 400°F (200°C). Place the assembled tarts on a baking sheet and bake for about 15 minutes until the pastry is golden brown and puffed, and the goat cheese begins to melt and brown in spots. Check every 2 minutes if additional time is needed to avoid burning. Let cool slightly before serving.

Notes

  • Use high-quality puff pastry for the best flaky texture.
  • Caramelize onions patiently over medium heat for deeper flavor; avoid high heat to prevent burning.
  • Thyme can be substituted with rosemary or sage if preferred.
  • Make the caramelized onions ahead of time and refrigerate until ready to assemble.
  • Serve warm or at room temperature with a glass of white wine for an elegant appetizer.
