# What You'll Need:

→ Flatbread

01 - 2 large flatbreads or naan

→ Caramelized Onions

02 - 2 large yellow onions, thinly sliced
03 - 2 tablespoons olive oil
04 - 1/2 teaspoon kosher salt
05 - 1/2 teaspoon sugar
06 - 1 tablespoon balsamic vinegar

→ Cheese

07 - 1 cup shredded mozzarella cheese
08 - 1/2 cup crumbled goat cheese or feta

→ Toppings

09 - 2 cups fresh arugula
10 - 2 tablespoons balsamic glaze

# How-To Steps:

01 - Preheat oven to 425°F.
02 - Heat olive oil in a large skillet over medium heat. Add sliced onions, salt, and sugar. Cook, stirring occasionally, until onions are deep golden brown and caramelized, approximately 20 to 25 minutes. Add balsamic vinegar in the final 2 minutes of cooking and stir to deglaze. Remove from heat.
03 - Place flatbreads on a baking sheet. Sprinkle mozzarella cheese evenly over each flatbread, then spread caramelized onions on top. Add crumbled goat cheese.
04 - Bake for 10 to 12 minutes, or until cheese is melted and flatbread is crisp.
05 - Remove from oven and let cool 2 minutes. Top with fresh arugula and drizzle with balsamic glaze. Season with black pepper.
06 - Slice and serve immediately.

# Expert Tips:

01 -
  • Those onions turn into pure caramel magic while you do something else, then everything comes together in under fifteen minutes flat.
  • It tastes like you spent all day cooking when really you just paid attention to one skillful, and honestly, the whole thing feels a bit fancy without demanding any actual fancy technique.
02 -
  • Caramelized onions cannot be rushed, and trying to turn up the heat will give you burned onions instead of the sweet, deep flavor you're after, so set a timer and be patient.
  • Adding the arugula after baking instead of before is the difference between this tasting fresh and bright versus like every other heavy pizza, so don't skip that step no matter how tempting it is.
03 -
  • Use a sharp knife to slice your onions as evenly as possible so they cook at the same rate and achieve that glossy, even caramelization.
  • Don't skip the balsamic glaze finish—it's the difference between good and memorable, and those two minutes of cooking time are when the onions get their personality.
