Ingredients
- 2 large onions, sliced
- 1 sheet puff pastry
- 2 tbsp butter
- 1 tsp thyme
- Salt and pepper to taste
- 1 egg, beaten (for egg wash)
Instructions
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Melt butter in a large skillet over medium heat. Add sliced onions and cook slowly, stirring occasionally, until they become soft and golden brown, approximately 15-18 minutes.
- Sprinkle thyme, salt, and pepper over the caramelized onions. Stir to combine and remove from heat. Let the onion mixture cool for 5-7 minutes.
- Roll out the puff pastry sheet on a lightly floured surface. Cut the pastry into 4 equal rectangles.
- Divide the caramelized onion mixture evenly among the pastry rectangles, placing it in the center of each piece.
- Fold the pastry edges over the onions, creating a rustic envelope-style package. Press the edges to seal.
- Brush each pastry package with beaten egg wash, ensuring complete coverage for a golden, shiny finish.
- Place the pastry packages on the prepared baking sheet, leaving space between each one.
- Bake in the preheated oven for 20-25 minutes, or until the pastry is puffed and golden brown.
- Remove from oven and let cool for 5 minutes before serving. Serve warm as an appetizer or light meal.
Tips
- Choose the right onions: Sweet varieties like Vidalia or yellow onions work best for caramelization.
- Low and slow is the key: Caramelize onions on medium-low heat to develop deep, rich flavors without burning.
- Don't skip the egg wash: It gives the pastry that professional, glossy golden-brown finish.
- Ensure your puff pastry is cold but pliable when working with it.
- Let the pastries rest for a few minutes after baking to allow the filling to set and prevent burning your mouth.
- Serve immediately for the crispiest pastry texture.
- Experiment with adding herbs like rosemary or a sprinkle of goat cheese for extra flavor complexity.
