Recipe Information
Ingredients
- 4 large Vidalia onions
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 teaspoons balsamic vinegar
- 1 teaspoon kosher salt
- 0.5 teaspoons black pepper
- 1 teaspoon fresh thyme leaves
- 4 sheets aluminum foil
Instructions
Preheat your grill to medium heat, approximately 375–400°F.
Peel the Vidalia onions, cutting off the pointed ends while keeping the root intact to hold the layers together.
Using a small paring knife, cut a shallow core out of the top center of each onion to create a small cavity.
Place a Vidalia onion on each sheet of aluminum foil. Shape the foil into a bowl-like form to hold the onion upright.
Into the cavity of each onion, add 1 tablespoon of unsalted butter, followed by a drizzle of about 1/2 tablespoon of olive oil and 1/2 teaspoon of balsamic vinegar.
Season each onion with a pinch of kosher salt, a pinch of black pepper, and a sprinkle of fresh thyme leaves.
Wrap each onion tightly in the foil, making sure the top is sealed to trap the steam during cooking.
Place the foil-wrapped onions on the grill, directly over the heat. Close the grill lid and cook for 25–30 minutes, flipping once halfway through cooking.
Check for doneness by carefully opening one of the foil packets and piercing the onion with a fork. It should be tender all the way through.
Remove the onions from the grill, carefully unwrap the foil, and serve warm as a side dish.
