Preheat your oven to 200°C (390°F). Line a baking sheet with parchment paper for easy cleanup.
Peel the carrots if the skins are thick or blemished, then cut them into evenly sized pieces, about 2-3 inches long, to ensure uniform roasting.
In a small bowl, whisk together the maple syrup, olive oil, a pinch of salt, black pepper, and herbs if using, until well combined.
Toss the carrot pieces in the maple glaze until they are thoroughly coated. Use a spatula or tongs to evenly distribute the glaze over each piece.
Arrange the glazed carrots in a single layer on the prepared baking sheet, making sure they aren’t overcrowded for even caramelization.
Roast in the oven for about 25-30 minutes, flipping or shaking the pan halfway through to promote even browning and caramelization. Look for deep amber color and crispy edges.
Once done, the carrots should be tender when pierced and coated with a sticky, glossy glaze. Remove from the oven and let rest for 5 minutes to allow flavors to settle.
Transfer the carrots to a serving dish, drizzle with any remaining glaze if desired, and sprinkle with a little extra salt or fresh herbs for garnish.
