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

Directions

Step 1

Preheat your grill to medium heat (about 375–400°F).

Step 2

Peel the outer skin of the onions and slice off the top and bottom to create a flat surface.

Step 3

Cut a small 'X' shape about 1/2-inch deep into the top of each onion.

Step 4

Place each onion onto a square of aluminum foil, ensuring there is enough foil to wrap the onion completely.

Step 5

Drizzle each onion with 1/2 tablespoon of olive oil and 1/2 tablespoon of balsamic vinegar.

Step 6

Sprinkle each onion with a pinch of salt, black pepper, and a few thyme leaves.

Step 7

Wrap each onion tightly in the foil to create a sealed packet.

Step 8

Place foil-wrapped onions on the grill, directly over the heat, and close the grill lid.

Step 9

Grill the onions for 20–25 minutes, turning them halfway through, until they are tender and caramelized.

Step 10

Carefully remove the packets from the grill and let them rest for 3 minutes before unwrapping.

Step 11

Open the foil carefully to avoid steam burns, and transfer the onions to a serving plate.

Step 12

Serve grilled sweet onions warm as a side dish or garnish with additional fresh thyme, if desired.
