Recipe Information
Ingredients
- 4 large sweet onions (e.g., Vidalia or Walla Walla)
- 2 tablespoons olive oil
- 2 tablespoons balsamic vinegar
- 1 teaspoon fresh thyme leaves
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper
- 4 sheets (12-inch squares) aluminum foil
Instructions
Preheat your grill to medium heat (about 375–400°F).
Peel the outer skin of the onions and slice off the top and bottom to create a flat surface.
Cut a small 'X' shape about 1/2-inch deep into the top of each onion.
Place each onion onto a square of aluminum foil, ensuring there is enough foil to wrap the onion completely.
Drizzle each onion with 1/2 tablespoon of olive oil and 1/2 tablespoon of balsamic vinegar.
Sprinkle each onion with a pinch of salt, black pepper, and a few thyme leaves.
Wrap each onion tightly in the foil to create a sealed packet.
Place foil-wrapped onions on the grill, directly over the heat, and close the grill lid.
Grill the onions for 20–25 minutes, turning them halfway through, until they are tender and caramelized.
Carefully remove the packets from the grill and let them rest for 3 minutes before unwrapping.
Open the foil carefully to avoid steam burns, and transfer the onions to a serving plate.
Serve grilled sweet onions warm as a side dish or garnish with additional fresh thyme, if desired.
