Ingredients

  • 2 tablespoons extra-virgin olive oil
  • 1 large onion, thinly sliced
  • Kosher salt
  • Fresh ground black pepper
  • 1/4 cup water
  • 1 large sweet apple, such as Fuji or Honeycrisp
  • 1 tablespoon lemon juice
  • 8 ounces shredded sharp cheddar cheese (about 2 cups)
  • 4 eight-inch flour tortillas
  • 2 tablespoons vegetable oil

Method

  • Heat the olive oil in a medium skillet.
  • Add the onion, season with salt and pepper and cook over moderate heat, stirring, until the onions are beginning to brown, about 8 minutes.
  • Add the water and cook until it has evaporated and the onion is very tender and lightly caramelized, about 10 minutes.
  • Let cool.
  • Dice the apple into 1/2-inch chunks and toss with the lemon juice.
  • Arrange the tortillas on a work surface and top each tortilla with cheese, apple and onion.
  • Fold each tortilla in half to make 4 quesadillas.
  • In a large skillet, heat the vegetable oil.
  • Add the quesadillas and cook over moderately high heat until golden and crisp, about 1 to 2 minutes per side.
  • Add more oil to the skillet if necessary.
  • Serve immediately.
