Ingredients

Scale
  • 1 ball pizza dough (12–14 oz)
  • 1 tablespoon olive oil (for brushing crust)
  • 1 tablespoon cornmeal or flour (for dusting baking sheet)
  • 2 large yellow onions, thinly sliced (about 3 cups)
  • 2 tablespoons unsalted butter (or vegan butter)
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt
  • 1 teaspoon sugar (optional, for caramelizing onions)
  • 1 tablespoon balsamic vinegar (optional)
  • 1–2 medium apples, thinly sliced (Honeycrisp or Granny Smith preferred)
  • 1–1 1/2 cups shredded mozzarella cheese (or fontina, gouda, or vegan alternative)
  • 1/4 cup crumbled goat cheese or feta (optional)
  • Fresh thyme leaves or chopped rosemary (optional)
  • Freshly ground black pepper, to taste

Instructions

  1. Preheat oven to 450°F (230°C). If using a pizza stone, place it in the oven to preheat. If using a baking sheet, line with parchment and dust with flour or cornmeal.
  2. Heat 2 tablespoons butter and 1 tablespoon olive oil in a large skillet over medium-low heat. Add sliced onions and 1/2 teaspoon salt. Cook, stirring occasionally, for about 10 minutes until softened.
  3. Add 1 teaspoon sugar (if using) and continue to cook, stirring every few minutes, until onions are deep golden brown and jammy, about 20–25 minutes. Lower heat and add a splash of water if onions brown too quickly.
  4. Stir in 1 tablespoon balsamic vinegar (optional) and remove from heat. Let cool slightly.
  5. On a lightly floured surface, stretch or roll out pizza dough to about 1/4-inch thick. Shape to fit your baking sheet or stone.
  6. Transfer dough to prepared baking sheet or parchment. Brush lightly with olive oil. Bake for 5–7 minutes until it starts to puff and set.
  7. Spread caramelized onions evenly over the par-baked crust. Layer thinly sliced apples on top. Sprinkle with shredded mozzarella and scatter goat cheese or feta if using. Add thyme or rosemary and black pepper to taste.
  8. Return flatbread to oven and bake for 10–15 minutes, until edges are golden and cheese is melted and bubbly. Apples should be slightly soft but not mushy.
  9. Let cool for a few minutes before slicing. Serve warm or at room temperature, garnished with extra herbs if desired.

Notes

For a crispier crust, par-bake the dough before adding toppings. Caramelize onions low and slow for best flavor. Use any melty cheese you like, and swap apples for pears or add nuts for variation. Flatbread can be made vegan or gluten-free with simple substitutions. Leftovers keep well in the fridge for up to 3 days or can be frozen for up to a month.
