Onion Tarte Tatin
 
 
Serves: 1 (12-inch) tart
Ingredients
  • 2 medium yellow onions
  • 1 medium red onion
  • ¼ cup unsalted butter
  • 2 tablespoons balsamic vinegar
  • 2 tablespoons honey
  • 1 tablespoon chopped fresh thyme
  • ¼ teaspoon kosher salt
  • ¼ teaspoon ground black pepper
  • ¼ cup finely grated fresh Parmesan cheese
  • ½ (17.3-ounce) package frozen puff pastry, thawed
  • Garnish: fresh thyme leaves
Instructions
  1. Preheat oven to 400°.
  2. Cut each onion lengthwise into 12 wedges, leaving root ends intact.
  3. In a 12-inch cast-iron skillet, melt butter over medium heat. Add onions; cook, turning occasionally, until just beginning to brown, about 5 minutes. Add vinegar and honey; cook for 5 minutes. Add thyme, salt, and pepper; sprinkle with Parmesan. Remove from heat.
  4. On a lightly floured surface, gently roll pastry sheet to remove crease lines. Using a knife, cut pastry into a 13-inch circle. Place pastry onto onions, carefully tucking edges down into skillet. Cut 2 small slits in top of pastry to release steam.
  5. Bake until pastry is puffed and golden brown, 20 to 25 minutes. Let stand for 5 minutes. Carefully invert tart onto a serving platter. Serve immediately. Garnish with thyme, if desired.
