Preheating the pan really helps to brown the carrots, so don't skip that part. 2. Make sure to dry the baby carrots off if they are wet from the package. They are packed in filtered water to keep them from drying out. Moisture inhibits browning, so taking the moment to do this makes a difference! 3. Note that we use an oven with high heat (425 degrees) which is hot enough to brown them, but not too hot so that the natural sugars burn. Make sure that your oven is fully preheated. 4. You also want to make sure the carrots are spread in an even layer and the pan is not overcrowded.
