Preheat your oven to 475°F (245°C). If you have a pizza stone, place it in the oven now.

Create the balsamic reduction by pouring balsamic vinegar into a small saucepan over medium heat. Add honey and stir gently. Bring to a simmer, then reduce heat to low and let it reduce by half for about 10-12 minutes.

Caramelize the onions by heating one tablespoon of olive oil in a skillet over medium-low heat. Add sliced red onions with a pinch of salt and cook slowly for about 15 minutes until soft and golden.

Roll out your pizza dough on a lightly floured surface into a 12-inch round or rectangle and transfer to your prepared baking sheet or pizza peel.

Brush the dough lightly with remaining olive oil.

Scatter caramelized onions evenly across the dough, then distribute crumbled goat cheese over the onions, and arrange fresh blueberries across the pizza.

Sprinkle fresh thyme leaves over everything and season with black pepper.

Bake the pizza for 12-15 minutes until the crust is golden brown and crispy.

Remove from the oven and immediately drizzle with the balsamic reduction. Top with fresh arugula if using.

Slice and serve immediately while hot.
