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

Directions

Step 1

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

Step 2

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.

Step 3

Add the balsamic vinegar to the onions and cook for an additional 2 minutes. Remove from heat and set aside to cool slightly.

Step 4

Grate the Parmesan cheese and set aside.

Step 5

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.

Step 6

Arrange the puff pastry pieces on the prepared baking sheet, leaving a little space between each piece.

Step 7

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.

Step 8

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.

Step 9

Season each piece with a small pinch of black pepper.

Step 10

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.

Step 11

Remove from the oven and allow to cool for 5 minutes before serving. Serve warm or at room temperature for a delicious appetizer.
