Ingredients

• 1 sheet puff pastry, thawed
• 2 large yellow onions, thinly sliced
• 3 tablespoons unsalted butter
• 1 teaspoon sugar
• 1/4 cup dry white wine or chicken broth
• 4 ounces Brie cheese, rind removed and cut into small pieces
• 1 teaspoon fresh thyme leaves (optional)
• 1 egg, beaten (for egg wash)
• Salt and pepper to taste

Equipment

• Large skillet or sauté pan
• Sharp knife
• Cutting board
• Baking sheet
• Parchment paper or silicone baking mat
• Pastry brush
• Mixing bowl
• Measuring spoons and cups

Instructions

1. Caramelize the onions: Heat the butter in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring occasionally, for about 15 minutes until they start to soften.
2. Add sugar and continue cooking: Sprinkle the sugar over the onions and continue cooking for another 15-20 minutes, stirring frequently, until the onions are deeply golden brown and caramelized. Be patient—this step is key for flavor.
3. Deglaze the pan: Pour in the white wine or chicken broth to deglaze, scraping up any browned bits on the bottom. Cook for 2-3 minutes until the liquid mostly evaporates. Season with salt, pepper, and fresh thyme if using. Remove from heat and let cool.
4. Prepare the puff pastry: Preheat your oven to 400°F (200°C). Roll out the thawed puff pastry on a lightly floured surface to smooth any creases. Cut the pastry into 12 equal squares.
5. Assemble the puffs: Spoon about a tablespoon of the caramelized onions onto the center of each pastry square. Top with a small piece of Brie cheese.
6. Fold and seal: Fold each pastry square into a triangle or rectangle, pressing the edges firmly to seal. Use a fork to crimp the edges for a decorative effect and to prevent leakage.
7. Apply egg wash: Place the puffs on a parchment-lined baking sheet. Brush the tops with the beaten egg to achieve a beautiful golden finish.
8. Bake: Bake for 15-18 minutes, or until the pastry is puffed and golden brown and the cheese inside is melted.
9. Cool slightly and serve: Allow the puffs to cool for a few minutes before serving. They are best enjoyed warm.

Tips & Variations

For perfectly caramelized onions, be patient and keep the heat moderate. Rushing this step can lead to burnt onions and a bitter taste.

• Cheese swap: Try Gruyère or Camembert instead of Brie for a different flavor profile.
• Add herbs: Fresh rosemary or sage can add a wonderful aroma and taste.
• Make it savory-sweet: Add a teaspoon of balsamic vinegar during deglazing for a tangy twist.
• Make mini versions: Cut the puff pastry into smaller squares for bite-sized party snacks.
• Prepare ahead: Caramelize onions and cut Brie a day ahead; assemble just before baking.
