Preheat oven to 375 degrees Fahrenheit. Scrub carrots clean and dry with paper towel.
Combine oil, basil, garlic and salt. Pour over dried carrots and gently stir to combine (directly on the cooking sheet).
Spread the carrots out in a single layer.
Bake for 35 minutes. Turn oven to off and set on low broil for 4-5 minutes. Watch those carrots closely as they can burn quickly. (I like to keep the oven light on to see the progress.)
