Ingredients

  • 1/4 cup extra-virgin olive oil, plus more for brushing
  • 2 pounds onions, thinly sliced
  • 1/3 cup white wine vinegar
  • 2 tablespoons dry white wine
  • Pinch of sugar
  • Kosher salt
  • Two 1-pound balls of frozen pizza dough, thawed
  • Cornmeal, for dusting
  • 1/2 cup oil-packed sun-dried tomatoes, drained and thinly sliced
  • 1/4 pound imported Fontina cheese, shredded
  • 1/4 pound mozzarella, shredded
  • 6 ounces andouille sausage, sliced 1/4 inch thick
  • 1 tablespoon minced flat-leaf parsley

Method

  • In a large saucepan, heat 1/4 cup of the olive oil until shimmering.
  • Add the onions and cook over moderate heat, stirring occasionally, until softened, about 5 minutes.
  • Add the vinegar, wine, sugar and a pinch of salt.
  • Cover partially and cook over low heat, stirring occasionally, until the onions are very soft, about 20 minutes.
  • Uncover and cook over moderate heat, stirring frequently, until browned, about 30 minutes longer; add water if the onions seem dry.
  • Transfer the onion confit to a bowl and let cool.
  • Meanwhile, set a pizza stone on the bottom shelf of the oven.
  • Preheat the oven to 500 for 30 minutes.
  • On a floured surface, roll out 1 ball of dough to a 14-inch round.
  • Transfer to a pizza peel or cookie sheet dusted with cornmeal.
  • Spread half of the onion confit over the dough to within 1 inch of the edge.
  • Top with half of the tomatoes, Fontina, mozzarella, andouille and parsley.
  • Lightly brush the edge with olive oil.
  • Slide the pizza onto the stone and bake for about 10 minutes, or until the crust is browned and the top is bubbling.
  • Let cool for 5 minutes, then cut into wedges and serve.
  • Meanwhile, repeat with the remaining dough and toppings.
  • Alternatively, if you don't have a pizza stone, assemble the pizzas on lightly oiled baking sheets coated with cornmeal.
  • Let rise for 30 minutes before baking directly on the sheet.
