Let's Cook
-
Step 1.
Heat the oven to 500°F (or 475°F if your oven cannot reach 500°F without broiling).
-
Step 2.
On a lightly floured surface, shape the pizza dough into a 14-inch oval. Transfer to a cornmeal-dusted or parchment-lined baking sheet. Spread the Dijon mustard evenly over the dough, then top with the sliced provolone cheese.
-
Step 3.
In a large bowl, combine the thinly sliced yellow onion, red onion, and fennel. Add the olive oil, fresh thyme leaves, ½ teaspoon salt, and ½ teaspoon pepper; toss to coat. Fold in the shredded Fontina cheese. Scatter the vegetable-cheese mixture evenly over the dough.
-
Step 4.
Bake until the crust is golden brown and the vegetables are just tender, 10 to 12 minutes. Sprinkle with finely chopped fresh parsley before serving.
