Cut each carrot into two inch long strips of around half inch thickness,If the strips are thin, they will burn quickly
Toss these strips in oil, salt and pepper
Arrange them in a single layer on a baking tray
Bake the carrots for 18-20 minutes, making sure to toss the tray after 10 minutes to avoid the carrots sticking to the pan
Serve immediately with tomato ketchup
