Recipe Information
Ingredients
- 4 whole sweet onions
- 3 tablespoons extra virgin olive oil
- 1 tablespoon balsamic vinegar
- 1 teaspoon fresh thyme leaves
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 tablespoon butter
Instructions
Preheat your oven to 400°F (200°C).
Peel the sweet onions and carefully cut them in half through the root end to help them hold their shape during roasting.
Lightly grease a baking dish with a bit of olive oil to prevent sticking.
Arrange the onion halves, cut side up, in the prepared baking dish.
Drizzle the onions with the olive oil and balsamic vinegar, ensuring they are evenly coated.
Sprinkle the fresh thyme leaves, salt, and black pepper over the onions.
Place a small dab of butter (about 1/8 tablespoon) on the top of each onion half for added richness.
Cover the baking dish tightly with aluminum foil to prevent drying out.
Place the dish in the preheated oven and roast for 30 minutes.
After 30 minutes, remove the foil and continue roasting for an additional 20 minutes or until the onions are golden brown and caramelized at the edges.
Remove from the oven and let the onions cool for a few minutes before serving.
Serve the roasted sweet onions warm as a side dish with your favorite main course, or enjoy them as a topping for steaks, burgers, or salads.
