Preheat your oven to 400°F (200°C).
Peel the red onions and cut each one into quarters, keeping the root end intact to help hold the layers together during roasting.
Place the onion quarters in a large mixing bowl.
In a small bowl, whisk together the balsamic vinegar, olive oil, brown sugar, fresh thyme leaves, sea salt, and black pepper until well combined.
Pour the balsamic mixture over the onions and gently toss to ensure the onions are evenly coated.
Arrange the onions in a single layer on a baking sheet or in a roasting dish, cut side up. Drizzle any remaining balsamic mixture from the bowl over the onions.
Roast the onions in the preheated oven for 35-40 minutes, turning them halfway through the cooking time, until they are tender and caramelized.
Remove from the oven and let the onions rest for a few minutes before serving.
Serve warm as a side dish or use them as a topping for your favorite dishes.
