- 2 tablespoons balsamic vinegar
- 1 teaspoon salt
- 0.5 teaspoon freshly ground black pepper
- 1 teaspoon fresh thyme leaves
- 2 garlic cloves, minced
Directions
Step 1
Preheat your oven to 400°F (200°C).
Step 2
Peel the onions and slice them in half through the root end. Trim the root end slightly but keep it intact so the layers hold together.
Step 3
Place the onion halves in a baking dish with the cut sides facing up.
Step 4
Drizzle the olive oil evenly over the onions to ensure they are well-coated.
Step 5
In a small bowl, whisk together the balsamic vinegar, salt, black pepper, minced garlic, and thyme leaves.
Step 6
Pour the balsamic mixture over the onions, ensuring all the onions get a coating of the flavorful liquid.
Step 7
Cover the baking dish with aluminum foil and place it in the preheated oven.
Step 8
Bake the onions for 45 minutes, then remove the foil and bake for an additional 15 minutes until the onions are tender and caramelized.
Step 9
Remove the baking dish from the oven and let the onions rest for about 5 minutes before serving.
Step 10
Serve the baked onions as a side dish or topping for steaks, burgers, or other entrees.
