Ingredients

• 4 large onions
• 3 tablespoons olive oil
• 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.
