Ingredients
- 1 baguette cut on diagonal into ½-inch slices
- 3 tablespoons olive oil divided
- 3 large yellow onions peeled and sliced thinly into semicircles
- 1 tablespoon brown sugar
- ½ cup water divided
- 1 tablespoon balsamic vinegar
- ½ teaspoon kosher salt
- 1 tablespoon minced fresh sage
- 3 ounces Pecorino Romano cheese
Instructions
- Preheat oven to 350 degrees F.
- Place baguette slices on a baking sheet and brush with about 2 tablespoons olive oil. Bake until lightly toasted, about 5 minutes. Set aside.
- For the onions, heat 1 tablespoon olive oil in a large skillet over medium heat.
- Add the onions and cook until softened, about 15 minutes.
- Stir in brown sugar. Cover and cook until the onions are golden brown, about 20 minutes, stirring occasionally.
- Add ¼ cup water, cover the pan again and cook until the onions are deep golden brown, about 15 minutes.
- Stir in balsamic vinegar, salt, sage and an additional ¼ cup water. Cover the pan and cook until the liquid is absorbed. Remove from heat.
- Using a vegetable peeler, shave off Pecorino Romano slices, one for each baguette slice.
- Divide the caramelized onions between the baguette slices and top each one with a slice of cheese.
- Place in oven and bake until cheese is beginning to melt, 3 to 4 minutes. Serve.
