Caramelized Three Onion and Thyme Pizza with Fontina Cheese

Summer means pizza on the grill. Even though it has cooled down a bit I’m not turning on the oven, especially to pizza baking temperatures. All in all, baked on a grill or in an oven, Caramelized Three Onion and Thyme Pizza with Fontina Cheese is a delicious not-your-usual pizza.

Aromatic earthy thyme accents both the caramelized onions and cheese. Earthy-flavored Italian Alpine Fontina goes really well with caramelized onions. Look for the original cheese, stamped with the DOP stamp and words Val d’Aosta on the label.

My family always made a Thanksgiving side dish called Onions Parmesan–lots of sliced onions sautéed in lots of butter, glazed with sherry vinegar and showered with Parmesan cheese. For this pizza I cooked the onions to the point that they shrink and begin to caramelize, and glazed them with both sherry wine and balsamic vinegar.

Pizza is fun to make on the grill!

Course: Appetizer, Main Course
Cuisine: Vegetarian
Keyword: pizza, grilled, caramelized onions
Servings: 4 small pizzas.
Author: Letty Flatt
Ingredients
The pizza dough:
  • ¾ cup warm water
  • ¾ teaspoon instant dry yeast
  • 1 tablespoon extra virgin olive oil
  • ¾ teaspoon fine sea salt
  • 1 cup whole-wheat flour
  • 1 cup to 1 ¼ cup all purpose flour
The pizza toppings:
  • 1 large red onion
  • 3 small yellow onions
  • 4 shallots
  • 3 tablespoons plus 3 tablespoons extra virgin olive oil
  • 2 tablespoons sherry wine vinegar
  • 1 tablespoon balsamic vinegar
  • fine sea salt
  • Freshly ground black pepper
  • 1 tablespoon chopped fresh thyme leaves
  • 12 ounces Val d’ Aosta Fontina cheese , grated
  • 2 cloves garlic , minced
Instructions
To make the dough:
  1. In a medium bowl, mix the warm water, yeast and 1 tablespoon of olive oil. Add the salt and one cup of the flour, stirring with a wooden spoon. Add the remaining flour, a cup at a time, stirring until it all comes together. You can work the dough in the bowl with your hands, turning it over to knead. Or you can turn the dough out onto a lightly floured work surface and knead. Either way, work the dough folding it over and pushing with the heels of your hands until the dough is well mixed, 3-5 minutes. Sprinkle with flour as needed to keep the dough from being too sticky.
  2. Place in an oiled bowl at least twice the volume of the dough. Cover with plastic wrap and let rise at room temperature until doubled in size, about 1 hour. While the dough is rising prepare the onion topping and grate the cheese. After the dough has risen an hour, turn the dough onto the counter and divide into 4 balls. Cover and let these rise for another 15 minutes.
For the topping and grilling:
  1. Cut the onions in half and slice them crosswise about 3/8-inch thick. Trim the shallots and cut them in half lengthwise, then slice thinly. Heat the first 3 tablespoons of olive oil in a large skillet on medium heat. Add the onions and shallots and cook, stirring frequently, until the onions are very soft, have shrunk to half of their original volume and have begun to turn brown on the edges. Add the vinegars, stirring to mix well. Season generously with salt and freshly ground pepper and the thyme leaves.
  2. Pre-heat the grill to high heat. Mix the remaining olive oil with the garlic and set aside. Flatten one dough ball at a time, and on a lightly floured work surface, using a lightly floured rolling pin, roll it into a circle, about 7-inches around and ¼-inch thick. You can pick it up with your hands and gently stretch it. Brush lightly with some of the garlic oil and invert onto a very hot grill. Bake 1 or 2 minutes until there are light grill marks. Turn over and cook the other side a minute. Remove to a clean work surface. When all the crusts are par-baked, lower the grill heat to medium.
  3. Brush the baked crusts with any remaining garlic oil. Sprinkle with a tablespoon or so of the Fontina cheese, and divide the onions between the crusts. Scatter the remaining cheese over the onions and sprinkle with salt and freshly ground pepper. Return the pizzas to the grill. Bake about 5 minutes, to melt the cheese and heat the onions.

  • […] the summer we cook our pizzas on the grill; in the winter it’s easier to bake pizzas in the oven. I love the convivial atmosphere […] Reply · 9 June, 2015

  • […] A hot pizza stone yields a super crisp crust. No stone? Use a baking sheet or a round pizza pan and allow a few more minutes for the pizza to bake. When it’s warm, in the summer, we bake our pizza outside, on the grill. Here’s how. […] Reply · 8 September, 2015
