After 20 minutes, remove the carrots from the oven. Pour sauce over carrots and toss until evenly coated. Spread back int an even layer. Bake an additional 15-25 minutes or until for tender. (Heirloom carrot varieties will roast in as little as 30 minutes total, but most carrots are denser and typically require 35 to 45 minutes total. Fresh carrots will require more time, older carrots will require less time.)
