Ingredients

1 sheet puff pastry, thawed
3 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon sugar
½ teaspoon salt
¼ teaspoon black pepper
4 ounces goat cheese, softened
2 tablespoons heavy cream or milk
1 teaspoon fresh thyme leaves (plus extra for garnish)
1 teaspoon balsamic vinegar (optional)
1 egg (for egg wash)
1 tablespoon water

Instructions

Prepare the onions:
Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions, sugar, salt, and pepper. Cook slowly, stirring occasionally, for 25–35 minutes until onions become deeply golden and caramelized. Stir in balsamic vinegar if using and let cool slightly.
Preheat oven:
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Prepare puff pastry:
Roll out the thawed puff pastry on a lightly floured surface. Cut into squares or rectangles depending on your desired tart size. Transfer to the prepared baking sheet.
Score borders:
Using a knife, lightly score a ½-inch border around each pastry piece without cutting through. This helps create a raised crust edge.
Make goat cheese mixture:
In a small bowl, mix softened goat cheese with cream or milk and thyme until smooth and spreadable.
Assemble tarts:
Spread a thin layer of goat cheese mixture inside the scored border. Top with a generous spoonful of caramelized onions.
Egg wash:
Whisk egg with water and brush along pastry edges for a golden finish.
Bake:
Bake for 15–20 minutes or until pastry is puffed and golden brown.
Garnish and serve:
Sprinkle with fresh thyme and serve warm or at room temperature.

The Secret to Perfectly Caramelized Onions

The star of this puff pastry tart recipe is undoubtedly the onions. Proper caramelization requires patience. Cooking them slowly over medium-low heat allows natural sugars to develop, creating that deep, sweet flavor without burning.

Tips for success:

Don’t rush the heat — low and slow is key.
Stir occasionally, not constantly.
A pinch of sugar enhances browning.
Deglaze with balsamic vinegar for extra depth.

The result should be jammy, golden, and intensely flavorful.

Choosing the Best Goat Cheese

Goat cheese adds creaminess and tang, balancing the sweetness of the onions. For best results:

Use soft, fresh goat cheese (chèvre style).
Let it come to room temperature before mixing.
Add a splash of cream to create a smooth spread.

You can also experiment with flavored goat cheese varieties like herb or honey-infused for unique twists.

Creative Variations

This easy elegant appetizer is highly customizable. Try these delicious ideas:
