Preheat oven to 400 degrees. Line a large baking sheet with parchment.
Wash, peel and cut carrots on the bias into similar sized pieces so they cook evenly.
In a large bowl combine the carrots, maple syrup, melted butter or coconut oil and springs of thyme. Season with salt and pepper. Stir well to combine all ingredients and coat the carrots well.
Pour carrots and seasonings onto the lined baking sheet or shallow baking dish. Bake in the oven for 20 minutes or until fork tender.
Remove from oven and strip the leaves off of the thyme sprigs. Throw the tough stems away and mix the leaves in with the carrots. Pour into a serving bowl and sprinkle a few more fresh thyme leaves on top for garnish if you wish.
