Set oven to 450F.
Slice carrots down the middle – vertically – to make two thin pieces. Place the halves in a bow.
Add olive oil, 1 tablespoon sugar-free maple syrup, thyme, cinnamon and sea salt & pepper. Rub the slices in the spices, then place them on a baking sheet with parchment paper.
Roast in the oven for 10 minutes, or until the edges are brown but have not burned.
Drizzle the remaining syrup over the carrots and serve immediately.
