A savory and comforting flatbread inspired by the flavors of classic French onion soup. Sweet caramelized onions, nutty Gruyere, and fragrant thyme create a delicious and easy lunch or appetizer.
Preheat oven to 450°F (232°C).
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, until the onions are softened and deeply caramelized, about 20-25 minutes. Stir in balsamic vinegar, if using, during the last 5 minutes of cooking.
While the onions are caramelizing, stretch or roll out the flatbread dough on a lightly floured surface to your desired shape and thickness. Transfer the dough to a baking sheet lined with parchment paper.
Brush the flatbread dough with the remaining 1 tablespoon of olive oil.
Spread the caramelized onions evenly over the flatbread dough.
Sprinkle the shredded Gruyere cheese over the onions.
Bake in the preheated oven for 10-12 minutes, or until the crust is golden brown and the cheese is melted and bubbly.
Remove from oven and sprinkle with fresh thyme. Slice and serve immediately.

For a richer flavor, add a splash of dry sherry or white wine to the onions during the last few minutes of cooking.
If you don't have Gruyere, you can substitute with Swiss cheese or a blend of mozzarella and Parmesan.
To prevent the flatbread from sticking to the baking sheet, use parchment paper or a silicone baking mat.
