A practical starting range for roasted carrots in the oven is 20-30 minutes at 218°C. This page is built to answer the cooking-time query fast without burying the useful part under a long recipe story.
Use the clock as guidance only and confirm doneness with a skewer test, texture check, or other reliable visual cue.
The result usually shifts most with piece size, sugar content, crowding, so treat the range as guidance rather than a guarantee.
