Slow-cooked onions turn deeply sweet and jammy, balanced by smoky bacon and melted cheese over a crisp flatbread base. It works as an appetizer, light lunch, or shareable snack with drinks, and the topping can be started while the crust proofs or simply spread over store-bought flatbread for a faster version.
Ingredients
- 1 prepared flatbread or pizza dough (about 12 inches)
- 2 tablespoons olive oil, divided
- 2 large yellow onions, thinly sliced
- 1/2 teaspoon salt
- 1/2 teaspoon sugar
- 1 tablespoon balsamic vinegar
- 6 slices bacon, cooked and crumbled
- 1 1/2 cups shredded mozzarella cheese
- 1/2 cup crumbled gorgonzola cheese
- 1 tablespoon fresh thyme leaves
- 1/4 teaspoon black pepper
Method
-
Heat 1 tablespoon olive oil in a 9-inch skillet over medium heat. Add the sliced onions, salt, and sugar, and cook, stirring occasionally, until softened, about 10 minutes.
-
Reduce heat to low and continue cooking the onions, stirring every few minutes, until deeply golden and caramelized, 25 to 30 minutes.
-
Stir in the balsamic vinegar and cook 1 minute, scraping up any browned bits. Remove from heat and set aside.
-
Preheat oven to 450°F. Place a baking sheet or pizza stone in the oven to heat.
-
Roll or stretch the flatbread dough into a 12-inch oval or rectangle on a piece of parchment paper. Brush the surface with the remaining 1 tablespoon olive oil.
-
Spread the caramelized onions evenly over the dough, leaving a 1/2-inch border. Sprinkle with mozzarella and gorgonzola, then scatter the crumbled bacon on top.
-
Slide the flatbread, still on the parchment, onto the preheated baking sheet or stone. Bake until the crust is golden and the cheese is bubbling, 12 to 15 minutes.
-
Remove from oven and sprinkle with fresh thyme and black pepper. Let rest 3 minutes before slicing.
