Caramelized Onion Tartlets

Cipollini onions are perfect for these tarts because they are small, flat, and sweet. You can also substitute shallots. You will need a mini-muffin tin.

Ingredients

  • All-purpose flour, for dusting
  • Pate Brisee (Pie Dough)
  • 3 tablespoons butter
  • 6 tablespoons sugar
  • 12 cipollini onions, peeled
  • Salt and freshly ground black pepper
  • 1 tablespoon balsamic vinegar
  • 2 sprigs fresh thyme

Directions

  1. Step 1

    On a lightly floured work surface, roll pate brisee to 1/8-inch thickness. Using a 2-inch-round biscuit cutter, cut out 12 circles. Transfer to a parchment-lined baking sheet, and refrigerate until needed.

  2. Step 2

    Melt butter in a heavy-bottomed skillet over medium heat. Sprinkle sugar over butter; cook, stirring, until sugar melts and starts to turn amber in color.

  3. Step 3

    Halve onions crosswise. Season cut surface with salt and pepper. Arrange onions in a single layer, cut side down, in skillet. Cook over medium-low heat, without turning, until caramelized sugar bubbles up around onions and onions are fragrant, about 15 minutes. Remove from heat.

  4. Step 4

    Using a slotted spoon or spatula to keep onions intact, transfer them to mini-muffin tins, placing half an onion, cut side down, in each cup (allow sugar syrup to remain in pan). Return skillet to low heat. Stir in balsamic vinegar, and season with salt and pepper and a few leaves of fresh thyme.

  5. Step 5

    Heat oven to 425 degrees. Quickly, before sugar cools, spoon a generous teaspoon sugar mixture into each muffin tin. Drape chilled pastry rounds over each onion, and using fingers, press to secure. Onions should be swaddled in pastry. Place muffin tin in oven; bake until pastry is golden brown and sugar bubbles up over pastry, about 20 minutes. Remove from oven. Immediately set baking sheet over muffin tin; invert, being careful of hot caramel that might drip from tin. Once you invert the tins, tarts will be right side up; serve garnished with fresh thyme leaves.

    Cooking times were okay for me. I would serve them at room temp. I found that they tasted better as they cooled. However I would use less sugar. Maybe 3 - 4 tablespoons

    The recipe for the dough Pate Brisee (Pie Dough) is not there when you click on it

    A friend made these this past weekend and the onions were too burned to eat. We thought 20 minutes at 425 after caramelizing for 15 minutes may have been too much. These are small tartlets. The concept is wonderful, but keep an eye on cooking time.
