Caramelized Onion Tart with Olives

Source: Martha Stewart Living, December 2007

Ingredients

  • 1 tablespoon unsalted butter
  • 2 tablespoons extra-virgin olive oil
  • 2 medium onions, thinly sliced
  • 2 tablespoons fresh thyme, leaves
  • All-purpose flour, for dusting
  • 1 sheet frozen puff pastry, thawed
  • 1/4 cup oil-cured small black olives, pitted and halved lengthwise
  • 4 to 6 anchovy fillets (optional), rinsed

Directions

  1. Preheat oven to 425 degrees. Melt butter with oil in a skillet over medium-high heat. Add onions and thyme, and cook until onions are golden and soft, about 10 minutes.

  2. On a lightly floured surface, roll out pastry, and trim to an 8 1/2-by-15-inch rectangle. Place on a parchment-lined baking sheet, transfer to oven, and immediately reduce oven to 400. Bake until pastry begins to rise, about 12 minutes.

  3. Arrange onions in a single layer over pastry, leaving a 1-inch border around edge. Top with olives and anchovies if using. Bake for 15 minutes. Reduce oven to 375 degrees, and bake until puffed and golden brown, about 15 minutes more (tent with foil if crust browns too quickly). Cut into squares.

    Delicious & easy. Definately take the time to very slowly carmelize the onions.

    this was delicious- couldn't find puff pastry dough so i used 7 sheets of filo dough (cut in half right out of the package), using a brush to spread melted butter in between layers. then i placed topping on the raw dough and baked at 325 for 20 minutes. i will definitely make this again, thank you
