Ingredients

• 2 large yellow onions, thinly sliced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 teaspoon sugar
• ½ teaspoon salt, plus more to taste
• 1 sheet frozen puff pastry, thawed
• 4 ounces fresh goat cheese, softened
• 1 large egg, beaten (for egg wash)
• 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
• Freshly ground black pepper, to taste
• Optional: 1 tablespoon balsamic glaze for drizzling

Directions

Prep the Onions

1. In a large skillet over medium-low heat, melt the butter with the olive oil.
2. Add the sliced onions and sprinkle with sugar and salt.
3. Cook, stirring every few minutes, until onions are deeply golden and caramelized—about 30-35 minutes.
4. If onions start to stick, add a splash of water and stir. Once done, remove from heat and let cool slightly.

Prepare the Pastry

5. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
6. On a lightly floured surface, unfold the puff pastry and gently roll into a 10x10-inch square.
7. Cut the pastry into 4 equal squares (or use a cookie cutter to make rounds for individual tarts).

Assemble the Tarts

8. Transfer the pastry squares onto the prepared baking sheet, spacing them out.
9. Spread a generous tablespoon of goat cheese onto each square, leaving a ½-inch border.
10. Spoon caramelized onions on top of the goat cheese.
11. Sprinkle with fresh thyme leaves and a bit of black pepper.
12. Brush the pastry edges with beaten egg for a golden finish.

Bake

13. Bake for 18-22 minutes, until the pastry is puffed and golden brown.
14. Let cool for 5 minutes before drizzling with balsamic glaze (if using) and serving.

Notes

• The onions can be caramelized up to 3 days ahead; store in the fridge.
• For extra crispiness, bake directly on the oven rack for the last 2 minutes.
• You can double the recipe by using a second sheet of puff pastry and doubling the toppings.

Variations

• Mushroom Lovers: Add sautéed mushrooms with the onions for earthy flavor.
• Cheese Swap: Try blue cheese or feta instead of goat cheese for a different twist.
• Mini Bites: Cut pastry into smaller squares or circles for perfect bite-sized hors d'oeuvres.

Required Equipment

• Large skillet
• Sharp knife and cutting board
• Rolling pin
• Measuring spoons
• Baking sheet and parchment paper
• Pastry brush

Storage Instructions

• Store leftover tarts in an airtight container in the refrigerator for up to 3 days.
• Reheat in a 350°F (175°C) oven for 8-10 minutes to restore crispness.
• Not recommended for freezing after baking, but you can freeze assembled, unbaked tarts.

Suggested Pairings & Serving Recommendations

• Serve with a fresh arugula or mixed greens salad for a lovely brunch or light lunch.
• Great with sparkling wine, Sauvignon Blanc, or a crisp cider.
• Drizzle with honey or balsamic glaze for a sweet-savory finish.

Pro Tips

• Let the onions cook low and slow; don't rush caramelization for best flavor.
• Softened goat cheese spreads more easily and prevents tearing the pastry.
• Be sure to chill puff pastry before baking if it’s become too soft to keep a flaky texture.

FAQ

Can I make these tarts ahead of time?

Yes! You can prep everything ahead and assemble and bake just before serving for optimal freshness.

What if I don’t have puff pastry?

You can use pre-made pie crust or crescent dough in a pinch, though the texture will differ.

Can I use red onions instead of yellow?

Absolutely! Red onions will yield a sweeter, slightly deeper flavor—feel free to experiment.
