Recipe Information
Ingredients
- 2 sheets puff pastry sheets
- 2 large yellow onions
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon fresh thyme leaves
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper
- 0.5 cup grated parmesan cheese
- 1 large egg
- 1 tablespoon water
Instructions
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Thinly slice the yellow onions. In a skillet, melt the butter with olive oil over medium heat.
Add the sliced onions to the skillet. Cook, stirring occasionally, for 15–20 minutes until the onions are caramelized and golden brown.
Stir in the thyme leaves, salt, and black pepper. Remove the skillet from the heat and let the mixture cool slightly.
On a lightly floured surface, roll out the puff pastry sheets if needed to smooth the seams. Cut each sheet into 6 equal squares.
Place a small spoonful of the caramelized onion mixture onto the center of each square. Sprinkle a pinch of grated parmesan on top.
Fold each square diagonally to form a triangle, pressing the edges firmly to seal. Use a fork to crimp the edges for extra security.
In a small bowl, whisk together the egg and water to make an egg wash. Brush the tops of the onion puffs with the egg wash.
Arrange the puffs on the prepared baking sheet, leaving space between each piece.
Bake for 18–22 minutes, or until the puffs are golden and flaky.
Remove from the oven and let cool slightly before serving. Enjoy your delicious onion puffs!
