Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Melt the butter in a large skillet over medium-low heat. Add the sliced onions and cook, stirring often, for about 20 minutes until soft and golden.

  2. Pour in the balsamic vinaigrette and cook, stirring, for about 10 minutes more until the onions are deep brown, sticky and most of the liquid has cooked off. Let cool slightly.

  3. Preheat the oven to 450°F (232°C). Roll or stretch the pizza dough on a lightly floured baking sheet or pizza pan to your desired shape.

  4. Spread the caramelized onions evenly over the dough, leaving a small border around the edge.

  5. Sprinkle about two-thirds of the shredded cheese blend over the onions, then arrange the sliced cherry tomatoes on top and scatter the remaining cheese over them.

  6. Bake for 12 to 15 minutes until the crust is golden brown and the cheese is melted and bubbling.

  7. Let the pizza rest for 2 minutes, then scatter the basil leaves over the top, slice and serve warm.
