Recipe Information
Ingredients
- 2 large yellow onions
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 tablespoon balsamic vinegar
- 1 teaspoon sugar
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper
- 1 package frozen puff pastry sheets
- 1 large egg
- 1 tablespoon water
Instructions
Peel and slice the yellow onions into thin rings.
In a large skillet, melt the butter and olive oil over medium heat.
Add the sliced onions to the skillet and sauté for about 10 minutes, stirring occasionally, until softened and just starting to caramelize.
Stir in the balsamic vinegar, sugar, salt, and black pepper. Cook for an additional 5-7 minutes until the onions are deeply caramelized. Remove from heat and let cool slightly.
Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Unfold the thawed puff pastry sheets on a lightly floured surface. Use a knife or pizza cutter to cut the pastry into 2-inch squares.
Place a small spoonful of caramelized onions in the center of each pastry square.
Fold each square into a triangle, pressing the edges together to seal. Use a fork to crimp the edges for extra security and decoration.
In a small bowl, whisk together the egg and water to create an egg wash. Brush the tops of the wrapped pastries with the egg wash.
Arrange the wrapped pastries on the prepared baking sheet, leaving space between each.
Bake in the preheated oven for 15-20 minutes, or until the pastry is golden brown and crispy.
Allow to cool slightly before serving. Enjoy these delightful appetizers warm or at room temperature.
