Recipe Information
Ingredients
- 4 pieces Large yellow onions
- 4 tablespoons Butter
- 2 tablespoons Brown sugar
- 2 tablespoons Balsamic vinegar
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 1 teaspoon Fresh thyme (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C).
Peel the onions and trim off the ends, taking care to maintain the onion's shape by cutting just enough.
Cut a small X score across the top of each onion to allow the flavors to seep in during cooking.
Place the onions in a baking dish, evenly spaced.
In a small saucepan, melt the butter over medium heat.
Add the brown sugar, balsamic vinegar, salt, and black pepper to the melted butter, stirring until the mixture is smooth and well combined.
Pour the butter mixture evenly over the onions, ensuring they are well coated.
Cover the baking dish with aluminum foil and bake for 40 minutes.
Remove the foil and baste the onions with the pan juices. Return to the oven uncovered and bake for an additional 20 minutes, or until the onions are tender and caramelized.
Remove the baking dish from the oven and let the onions rest for 5 minutes.
Garnish with fresh thyme, if using, and serve warm as a side dish.
