Bbq chicken pizza

1. For the dough:
Whisk the water and sugar together in the bowl of a stand mixer fitted with a dough hook, then sprinkle the yeast on top. Set aside until the mixture bubbles, about 10 minutes.

2. Add the flour, measured oil, and salt and mix on low speed until the dough just starts to come together and looks shaggy, about 2 minutes.

3. Increase the speed to medium and continue to mix until the dough is elastic and smooth, about 5 minutes. Meanwhile, coat a large bowl with a thin layer of oil and set it aside.

4. When the dough is ready, form it into a ball, place it in the oiled bowl, and turn to coat it with the oil. Cover the bowl tightly with plastic wrap.

5. Let the dough rest in a warm place until it doubles in size, about 1 hour. Meanwhile, make the sauce.

6. For the barbecue sauce:
Place all of the ingredients in a medium saucepan and bring to a simmer over medium heat, whisking occasionally. Reduce the heat to low and continue to simmer, whisking occasionally, until the flavors have mingled and the sauce has reduced to about 1 cup, about 30 minutes.

7. Remove the pan from the heat and let the sauce cool to room temperature.

8. For the pizza:
Once the dough has risen, punch it down, turn it out onto a work surface, and form it into a ball. Return the dough to the bowl, cover tightly with plastic wrap, and let rest for 15 to 20 minutes. Meanwhile, heat the oven to 525°F and arrange a rack on the bottom.

9. Transfer the dough to a baking sheet. Using your hands, stretch and shape it into a rough 16-by-12-inch rectangle. Using a fork, prick the dough all over, being careful not to poke all the way through.

10. Evenly spread all of the cooled barbecue sauce over the dough, leaving about a 1/2-inch border around the edge. Evenly scatter the chicken over the sauce, sprinkle both cheeses over the chicken, and scatter the onion over the cheese.

11. Bake until the crust is golden brown and the cheese has melted, about 20 minutes. Transfer to a cutting board, cut into slices, and serve.
