- Prep Time
- 1 tablespoon olive oil
- 1 large sweet onion, thinly sliced
- 1 clove garlic, minced
- 1 large Pink Lady or Fuji apple, thinly sliced
- 1 tablespoon cider vinegar
- 1 pound ground turkey
- 1 tablespoon Worcestershire sauce
- 1 teaspoon onion powder
- 1/2 teaspoon garlic powder
- Room-temperature butter
- 8 slices whole-wheat bread
- 8 slices extra-sharp white cheddar (preferably from New York State, in honor of Rach!)
In a cast-iron or large, heavy skillet, heat the oil over medium-high. Add the onion and cook until it begins to soften, about 2 minutes. Add the minced garlic; stir 1 minute. Add the apple, and season with salt and pepper. Reduce the heat to low and cook, stirring occasionally, until very soft and golden brown, about 20 minutes. Remove from the heat and stir in the vinegar. Transfer the onion-apple mixture to a plate and wipe out the skillet.
In a large bowl, mix the ground turkey, Worcestershire, onion powder, garlic powder, 1 tsp. salt and 1/4 tsp. pepper. Form into four 1/2-inch-thick patties, each about the size of the bread. Heat the same skillet over medium. Add the patties to the skillet and cook until browned and cooked through, 3 to 4 minutes per side. Transfer to a plate; wipe out the skillet.
Butter the bread on one side. Place 4 bread slices, buttered sides down, on a work surface. Top each with a slice of cheese, a patty, some of the onion-apple mixture and another slice of cheese. Top with the remaining bread, buttered sides up.
Heat the same skillet over medium. Working in batches if needed, cook the burgers until the bread is golden brown and the cheese melts, about 3 minutes per side. Cut burgers in half.
