Recipe Information
Ingredients
- 4 whole sweet onions
- 3 tablespoons olive oil
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 4 sprigs fresh thyme
- 1 tablespoon balsamic vinegar (optional)
Instructions
Preheat your oven to 400°F (200°C).
Peel the sweet onions, trimming off the stem and root ends, but leaving the onions intact.
Cut each onion in half vertically through the root end.
Place the onions cut-side up in a baking dish or parchment-lined baking tray.
Drizzle the olive oil evenly over the onions, ensuring they are well-coated.
Sprinkle the onions with salt and black pepper to taste.
Distribute the fresh thyme sprigs among the onions for added flavor.
If using balsamic vinegar, drizzle it lightly over the onions for a touch of acidity and sweetness.
Cover the baking dish loosely with aluminum foil to prevent excessive browning during the first half of cooking.
Place the dish in the preheated oven and roast for 25 minutes.
Remove the foil, then continue roasting for an additional 15 minutes, or until the onions are golden brown, tender, and slightly caramelized.
Remove the onions from the oven and let them cool slightly before serving.
Serve the roasted onions as a side dish, or use them as a topping for steaks, burgers, or salads.
