Recipe Information
Ingredients
- 4 large Vidalia onions
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- 0.5 teaspoons black pepper
- 0.5 teaspoons garlic powder
- 1 tablespoon fresh thyme leaves (optional)
- 4 sheets (approximately 12x12 inches each) aluminum foil
Instructions
Preheat your grill to medium heat (about 375°F/190°C).
Peel the Vidalia onions, removing the papery outer layers, and cut off just the tip of the root end while leaving the base intact to keep the onion whole.
Using a sharp knife, cut a deep 'X' into the top of each onion, going about halfway down but not through the bottom.
Place each onion on a sheet of aluminum foil and gently pull apart the 'X' to create a small cavity in the center of each onion.
Place 1 tablespoon of unsalted butter into the cavity of each onion.
Drizzle each onion with 1/2 tablespoon of olive oil and season generously with kosher salt, black pepper, and garlic powder.
If desired, sprinkle the fresh thyme leaves into the cavity for added flavor.
Wrap each onion tightly in the aluminum foil, ensuring there are no gaps in the foil to allow steam to escape.
Place the wrapped onions directly on the preheated grill and close the lid.
Cook for 35-40 minutes, turning the onions once or twice to ensure even cooking. The onions are done when they are tender and caramelized.
Carefully remove the foil packets from the grill and let them rest for 5 minutes before unwrapping. Be cautious of the hot steam when opening the packets.
Serve the grilled Vidalia onions as a side dish or use them as a topping for your favorite grilled dishes.
