How to Make Irresistible Caramelized Onion and Goat Cheese Tarts
Caramelize Onions: In a skillet, heat olive oil and butter over medium heat. Add sliced yellow onions, along with sugar, salt, and pepper. Cook undisturbed for about 15 minutes until the onions turn golden brown and soft, stirring occasionally. Then, add balsamic vinegar and thyme, and cook for another 5 minutes until the mixture becomes jammy and aromatic.
Assemble Tarts: Roll out the thawed puff pastry on a floured surface, and cut it into rectangles or squares. Evenly spread a generous layer of the caramelized onion mixture onto each piece, leaving a small border around the edges. Crumble goat cheese over the top of the onions, ensuring a luscious layer.
Bake: Preheat your oven to 400 °F (200 °C). Place the assembled tarts on a lined baking sheet and bake for approximately 15 minutes or until the pastry is golden and puffed, and the goat cheese is melting. Check every 2 minutes to prevent burning.
Optional: Drizzle with a bit of honey before serving for a delightful sweet touch.
