Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Prepare the Onions: In a large skillet, heat olive oil and butter over medium heat. Add the sliced onions, salt, and pepper. Cook, stirring occasionally, for 20-25 minutes until the onions are soft and caramelized. If desired, add sugar to enhance sweetness.
- Prepare the Puff Pastry: Roll out the puff pastry onto the prepared baking sheet. Score a 1-inch border around the edges without cutting all the way through. Prick the center with a fork to prevent it from puffing up.
- Assemble the Tart: Spread the caramelized onions evenly over the center of the pastry. Drizzle with heavy cream and sprinkle with Parmesan cheese and thyme leaves.
- Bake: Place the tart in the oven and bake for 20-25 minutes, or until the pastry is golden brown and crisp.
- Serve: Let the tart cool slightly before slicing. Garnish with crumbled goat cheese or fresh parsley if desired. Serve warm or at room temperature.
Tips
- Caramelize Slowly: Take your time when caramelizing the onions for the best flavor.
- Use Store-Bought Pastry: Save time by using ready-made puff pastry.
- Experiment with Cheeses: Try blue cheese, Gruyère, or Fontina for different flavor profiles.
- Make Ahead: The onions can be caramelized in advance and stored in the fridge until ready to use.
