01 - Preheat your oven to 475°F. If utilizing a pizza stone, ensure it is placed within the oven during the preheating phase to warm thoroughly.
02 - In a small bowl, combine the shredded cooked chicken breast with 2 tablespoons of barbecue sauce, tossing to coat evenly. Set aside.
03 - On a lightly floured work surface, roll the pizza dough into a 12-inch circular shape. Carefully transfer the dough to a parchment-lined baking sheet or directly onto the preheated pizza stone.
04 - Lightly brush the prepared pizza dough with olive oil. Evenly spread 1/2 cup of barbecue sauce over the dough, ensuring a 1/2-inch border remains uncovered.
05 - Generously sprinkle both the mozzarella and smoked Gouda (or cheddar) cheeses uniformly over the barbecue sauce base.
06 - Evenly scatter the prepared barbecue chicken and thinly sliced red onions over the cheese layer.
07 - Bake the pizza for 12 to 15 minutes, or until the crust achieves a golden-brown hue and the cheese is thoroughly melted and bubbling.
08 - Carefully remove the baked pizza from the oven. Drizzle with additional barbecue sauce to taste, then sprinkle generously with fresh chopped cilantro. Slice into portions and serve immediately while hot.
