Preheat oven to 375 F. In a bowl mix your honey, balsamic vinegar, olive oil and seasoning to taste.
In a tray, combine your carrots, thyme and 3/4 of your glaze, ensuring you cut the carrots as evenly as possible. Roast for 15-20 mins or until the carrots start to caramelize.
Take the try out the oven, flip the carrots and pour over the rest of your glaze. Pop back in the oven until nicely browned and sticky. This can take up to another 20-25 mins depending on the size of your carrots. Don't raise the heat to try and speed things up as the vinegar/honey will burn.
Serve by pouring over any leftover glaze from the pan, and a sprinkle of fresh parsley. If you particularly love balsamic vinegar then use the brush to flick over some at serving, or if you particularly love honey then give them a tiny drizzle.
