Preheat your oven to 400°F (200°C).
Peel the red onions, leaving them whole, and cut them in half lengthwise through the root so they hold together.
Place the onion halves in a roasting dish, cut-side up.
Drizzle the olive oil and balsamic vinegar evenly over the onions, ensuring each half is coated.
Scatter the fresh thyme sprigs over and around the onions.
Season with sea salt and freshly ground black pepper to taste.
Cover the roasting dish with aluminum foil and roast in the preheated oven for 30 minutes.
After 30 minutes, remove the foil and return the dish to the oven. Roast uncovered for another 15 minutes, or until the onions are golden, soft, and slightly caramelized on top.
Remove from the oven and let the onions cool slightly before serving.
Serve warm as a side dish or incorporate into salads or grain bowls for added sweetness and depth of flavor.
