- Preheat your oven to 425°F (220°C) to ensure perfect caramelization.

- In a large ovenproof casserole dish, combine unsalted butter and olive oil. Melt slightly, then stir in balsamic vinegar, wine, salt, sugar, and pepper.
- Arrange the onion halves cut side down in the dish, ensuring even cooking.
- Cover with aluminum foil and bake for 20 minutes to soften the onions.
- Remove foil, flip the onions cut side up, brush with pan juices, and roast uncovered for an additional 20-25 minutes.
- Once done, let them cool slightly and garnish with fresh herbs before serving.
