Ingredients

The following ingredients have 4 Servings
  • 2 teaspoons vegetable oil
  • 2 medium white onions, thinly sliced (about 4 cups)
  • 2 teaspoons Kosher salt
  • 1/2 teaspoon fresh black pepper
  • 1/4 cup sugar
  • 1/3 cup balsamic vinegar
  • 2 Tablespoons olive oil
  • 2 garlic cloves, minced
  • 2 cups shredded gruyere
  • 1 recipe The Ultimate Pizza Dough, or 20 oz. store-bought pizza dough
  • Cornmeal, for dusting sheet tray or pizza stone
  • Chopped chives, for garnish

Instruction

  • Begin by preparing the onions. Heat the vegetable oil in a large skillet over medium heat for 2 minutes.
  • Add the onions, salt, and pepper and cook, stirring occasionally, for 20 minutes until onions are soft.
  • Add the sugar and reduce the heat to medium-low. Cook the onions, stirring frequently, for 10 minutes.
  • Add the balsamic vinegar and reduce the heat to low. Continue cooking the onions, stirring occasionally, for 1 hour until they are very soft and dry. Set aside.
  • Preheat oven to 500ºF.
  • Roll out the prepared pizza dough on a lightly floured surface until it is roughly ¼-inch thick.
  • Invert a cookie sheet and sprinkle it liberally with cornmeal. Transfer dough to cornmeal-dusted sheet tray. (See Kelly's Notes.)
  • Combine the olive oil and garlic and brush it over the dough, leaving a ½-inch border along the edges. Top it with half of the shredded gruyere, then sprinkle on the prepared balsamic onions and top with the remaining cheese.
  • Bake pizza for 10 to 12 minutes, rotating half-way through, until crust is fully baked and golden brown.
  • Garnish with chopped chives, slice and serve.
