Caramelized onion and goat cheese “tart”

Uh-oh! We're unable to calculate nutrition for this recipe because some ingredients aren't recognized.

Step 1

Preheat oven to 190°c (375f). Line 2 baking sheets with parchment.

Step 2

In a large skillet over medium heat, heat oil and butter. Add onions, 2 teaspoons salt, and 1/4 teaspoon pepper and cook, stirring occasionally, until very onions are very caramelized, about 35 minutes. Stir in vinegar and thyme. Let cool to room temperature.

Step 3

On a lightly floured surface, cut each puff pastry sheet into 9 squares. Transfer squares to prepared sheets.

Step 4

Top each with about 1 tablespoon onions, leaving a 1 cm border on all sides. Brush exposed edges with egg. Divide goat cheese among squares.

Step 5

Bake tarts, rotating sheets halfway through, until puffed and golden brown, 25 to 28 minutes.

Step 6

Drizzle a little honey on each tart.

Step 7

Top with more thyme and pepper. Serve immediately or at room temperature.
