Recipe Information
Ingredients
- 1 sheet Puff pastry sheet
- 2 medium Red onion
- 100 grams Parmesan cheese
- 2 tablespoons Olive oil
- 1 tablespoon Balsamic vinegar
- 1 teaspoon Fresh thyme leaves
- 0.5 teaspoon Salt
- 0.25 teaspoon Black pepper
- 1 large Egg
- 1 tablespoon Water
Instructions
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
Peel and thinly slice the red onions. Heat the olive oil in a skillet over medium heat, then add the onions and a pinch of salt. Cook for 8-10 minutes, stirring occasionally, until softened and lightly caramelized.
Add the balsamic vinegar to the onions and cook for an additional 2 minutes. Remove from heat and set aside to cool slightly.
Grate the Parmesan cheese and set aside.
Roll out the puff pastry sheet on a lightly floured surface to ensure even thickness. Cut the pastry into 12 equal squares or circles, depending on your preferred shape.
Arrange the puff pastry pieces on the prepared baking sheet, leaving a little space between each piece.
In a small bowl, whisk together the egg and water to create an egg wash. Lightly brush the edges of each pastry piece with the egg wash.
Place a small spoonful of caramelized onion in the center of each pastry piece, spreading it out slightly. Sprinkle a generous amount of grated Parmesan cheese over the top and add a few fresh thyme leaves.
Season each piece with a small pinch of black pepper.
Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and puffed, and the cheese is melted and lightly golden.
Remove from the oven and allow to cool for 5 minutes before serving. Serve warm or at room temperature for a delicious appetizer.
