Line a rimmed baking sheet with parchment paper. Place carrots on parchment paper and drizzle with olive oil. Gently toss with your hands to evenly coat each carrot with the oil. Sprinkle with salt and fresh thyme leaves.
Place baking tray in pre-heated oven and roast for approximately 15-20 minutes. Remove from oven and turn each carrot to expose the bottom side. Return to oven and roast another 5-10 minutes or until they start to brown.
