01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.

03 - Drizzle olive oil over the vegetables, then sprinkle with sea salt, black pepper, and thyme. Toss to coat evenly.
04 - Spread vegetables in a single layer on the prepared baking sheet to ensure even roasting.
05 - Roast for 30 minutes, stirring once halfway through, until the vegetables are tender and starting to caramelize.
06 - While roasting, whisk together balsamic vinegar and maple syrup or honey in a small bowl.
07 - Remove the vegetables from the oven and drizzle with the balsamic glaze. Toss gently to coat evenly.
08 - Return the glazed vegetables to the oven for an additional 8 to 10 minutes until the glaze is bubbling and caramelized.
09 - Serve hot, optionally garnished with extra fresh thyme.
