- Step 6: Bake for 15–18 minutes, or until the pastry is puffed and golden and the cheese is slightly melted.
- Step 7: Let the tarts cool slightly before serving. Garnish with extra thyme if desired.
Tips & Variations

- You can caramelize the onions up to 3 days in advance and store them in the refrigerator.
- Try adding a drizzle of honey before serving for a sweet-savory twist.

FAQs
Can I use a different type of cheese?
Yes, cream cheese or ricotta can be used as alternatives, but goat cheese adds a distinctive tangy flavor that complements the onions well.
How do I keep the puff pastry from getting soggy?
Keep the puff pastry chilled until just before baking and avoid adding too much filling to prevent sogginess. Baking on a parchment-lined sheet also helps ensure crispiness.

Ingredients
Pastry
- 1 sheet puff pastry (thawed but still cold)
Caramelized Onions
- 2 large onions, thinly sliced (yellow or sweet)
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- Salt and pepper to taste
- 1 teaspoon balsamic vinegar
- 1 teaspoon fresh thyme leaves
Topping
- 4 ounces goat cheese, crumbled
Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and for easy cleanup.
- Caramelize the Onions: In a large skillet, heat the olive oil and butter over medium heat. Add the thinly sliced onions along with the sugar, salt, and pepper. Stir occasionally for about 15 minutes until the onions soften and turn a beautiful golden color.
- Add Flavorings: Stir in the balsamic vinegar and fresh thyme leaves. Continue cooking for another 5 minutes, allowing the onions to become jammy and deeply caramelized. Remove the skillet from the heat and let the onions cool slightly.
- Prepare the Puff Pastry: On a lightly floured surface, roll out the puff pastry sheet evenly. Cut it into 6 equal-sized rectangles or circles, depending on your preference. Arrange the pastry pieces on the prepared baking sheet.
- Assemble the Tarts: Spoon the caramelized onions onto each pastry piece, leaving a small border around the edges to allow the pastry to puff. Evenly distribute the crumbled goat cheese over the onions.
- Bake: Place the baking sheet in the preheated oven and bake for 15 to 18 minutes, or until the puff pastry is golden brown and puffed, and the goat cheese is slightly melted.
- Serve: Allow the tarts to cool slightly before serving. Optionally, garnish with extra thyme leaves for a fresh, aromatic touch.
Notes
- Keep puff pastry cold until ready to bake to ensure the best rise and flakiness.
