Ingredients

  • 4 large Yellow onions
  • 3 tablespoons Olive oil
  • 1 teaspoon Salt
  • 0.5 teaspoon Black pepper
  • 1 teaspoon Fresh thyme
  • 2 teaspoons Balsamic vinegar (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or foil for easy cleanup.

Step 2

Peel the onions and slice them in half through the root. Leave the root intact to help the onion halves hold together.

Step 3

Place the onion halves cut-side up on the prepared baking sheet.

Step 4

Drizzle the olive oil evenly over the onions, ensuring each half is well-coated.

Step 5

Sprinkle the onions with salt, pepper, and fresh thyme for seasoning.

Step 6

If using balsamic vinegar, drizzle it lightly over the onions to add a touch of rich sweetness.

Step 7

Place the baking sheet in the preheated oven and roast the onions for 40-45 minutes, or until they are golden brown, tender, and slightly caramelized around the edges.

Step 8

Remove the onions from the oven and allow them to cool slightly before serving.

Step 9

Serve warm as a side dish or use in salads, pasta, or as a topping for roasted meats.
