Preheat the oven to 400℉. Line a baking sheet with foil or parchment paper or nonstick cooking spray.
Peel the carrots (optional) and slice them into 3" pieces. Slice each one in half if they are too thick.
Add all ingredients to a bowl with the sliced carrots and toss everything together.
Spread onto a prepared baking sheet. Bake for 35-45 mins, flip halfway through. Check for doneness by poking with a fork. Sprinkle with more parmesan cheese if desired and bake an additional 1-2 minutes.
