Recipe Information
Ingredients
- 4 pieces Large onions (yellow, white, or red)
- 2 tablespoons Olive oil
- 1 teaspoon Salt
- 0.5 teaspoons Black pepper
- 1 tablespoon Balsamic vinegar (optional)
- 2 sprigs Fresh thyme (optional)
Instructions
Preheat your oven to 400°F (200°C).
Peel the onions, trim the bottoms slightly to create a flat base, and cut each onion in half from root to tip.
Drizzle a baking dish or sheet pan with 1 tablespoon of olive oil to lightly coat the surface.
Place the onion halves cut-side up in the baking dish and drizzle with the remaining 1 tablespoon of olive oil.
Sprinkle the onions with salt and black pepper, ensuring even distribution.
If using, drizzle the onions with balsamic vinegar for added flavor and place the fresh thyme sprigs on top or alongside the onions.
Cover the dish tightly with aluminum foil and roast in the oven for 25 minutes to allow the onions to soften.
Remove the foil and roast uncovered for an additional 20 minutes, or until the onions are golden brown and caramelized around the edges.
Remove the onions from the oven and let them cool slightly before serving as a side dish or topping for your favorite meals.
