Recipe Information
Ingredients
- 2 tablespoons Butter
- 2 large Yellow onions, thinly sliced
- 1 teaspoon Granulated sugar
- 0.5 teaspoon Salt
- 0.5 teaspoon Black pepper
- 1 tablespoon Balsamic vinegar
- 1 package Puff pastry sheets, thawed
- 1 cup Gruyere or cheddar cheese, shredded
- 1 teaspoon Fresh thyme leaves (optional)
- 1 large Egg, beaten (for egg wash)
Instructions
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Heat the butter in a large skillet over medium heat. Add the sliced onions and cook for 15-20 minutes, stirring occasionally, until they are soft and caramelized.
Sprinkle in the sugar, salt, and black pepper. Stir well and cook for another 2 minutes.
Add the balsamic vinegar and stir to deglaze the pan. Cook for an additional 2 minutes, then remove from heat and set aside.
On a lightly floured surface, roll out the thawed puff pastry sheet slightly and cut it into 12 equal squares.
Place the puff pastry squares on the prepared baking sheet, leaving a little space between each square.
Using a knife, lightly score a smaller square inside each pastry, being careful not to cut all the way through. This will create a border and allow the edges to puff up.
Distribute the caramelized onions evenly inside the scored squares, then sprinkle the shredded cheese on top of the onions.
Brush the edges of the puff pastry squares with the beaten egg wash.
Bake in the preheated oven for 15-18 minutes, or until the pastry is golden brown and puffed, and the cheese is melted and bubbly.
Remove from the oven and let cool for 5 minutes before serving. If desired, sprinkle fresh thyme leaves on top for garnish.
Serve warm and enjoy these flaky, cheesy tartlets as an appetizer or snack!
