Ingredients
- 1 sheet of puff pastry, thawed
- 2 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- Salt and pepper to taste
- 1 cup grated Gruyère cheese
- 1 egg, beaten (for egg wash)
- Fresh thyme leaves for garnish (optional)
Instructions
- Preheat the Oven: Preheat your oven to 400°F (200°C).
- Caramelize the Onions: In a large skillet, heat olive oil and butter over medium heat. Add the sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, for about 20-25 minutes until the onions are golden brown and caramelized.
- Prepare the Pastry: Roll out the puff pastry on a lightly floured surface. Cut into squares or circles to fit into a muffin tin or tartlet molds.
- Assemble the Tartlets: Place the pastry pieces into the molds. Spoon the caramelized onions into each pastry shell, then top with grated Gruyère cheese.
- Bake: Brush the edges of the pastry with the beaten egg. Bake in the preheated oven for 15-20 minutes, or until the pastry is golden and the cheese is bubbly.
- Serve: Allow to cool slightly before removing from the molds. Garnish with fresh thyme if desired and serve warm.
