Preheat the oven to 400ºF/205ºC degrees. Spray a 9x13 baking dish with nonstick cooking spray.
Place the cut carrots in a large mixing bowl.
Pour the melted butter and oil over the carrots. Then add the brown sugar, salt and cinnamon. Stir well to coat the carrots.
Place the carrots in a single layer in the baking dish.
Bake for 25-30 minutes, turning them after 15 minutes. The carrots should be fork tender when cooked.
Remove from the oven and serve immediately.
Notes
To get more caramelized carrots, spread them on a large baking sheet with space between the carrots. Follow the remaining directions.
For a great Asian side dish replace the cinnamon with ground ginger.
You can use baby carrots in place of cut carrots.
