Ingredients
 

Main Ingredients

  • 8 oz puff pastry, thawed cut into squares
  • 1.25 lb yellow onions, thinly sliced
  • 1.5 tbsp olive oil
  • 1.5 tbsp unsalted butter
  • 1.5 tsp light brown sugar
  • 2 tsp balsamic vinegar plus more for drizzling, if desired
  • 0.75 tsp kosher salt divided
  • 0.5 tsp freshly ground black pepper
  • 6 oz soft goat cheese room temperature
  • 1 tsp fresh thyme leaves, chopped divided
  • 3 tbsp beaten egg for egg wash
  • 1 tbsp water to loosen egg wash
  • 1 tbsp all-purpose flour for dusting
  • 1 tsp honey optional drizzle

Instructions

Preparation Steps

  • Heat oven to 400°F. Line a baking sheet with parchment.
  • Warm olive oil and butter in a large skillet over medium heat.
  • Add onions and 1/2 teaspoon salt. Cook, stirring occasionally, until deeply golden, 25–30 minutes.
  • Stir in brown sugar and balsamic. Cook 2 minutes to glaze. Add pepper and half the thyme.
  • Lightly flour the counter. Roll puff pastry to smooth seams and slightly enlarge.
  • Cut pastry into eight squares. Transfer to the sheet and dock centers with a fork.
  • Whisk egg with water. Brush pastry borders, avoiding the centers.
  • Crumble goat cheese onto centers. Spoon a mound of onions over the cheese.
  • Bake until puffed and deeply golden, 18–22 minutes.
  • Rest 5 minutes. Sprinkle remaining thyme and drizzle honey or extra balsamic. Serve warm.

Notes

Variation: Add a few thinly sliced figs or pear to the onions during the last 5 minutes for a fruity note. Storage: Reheat leftovers at 350°F for 8–10 minutes to re-crisp the pastry.
