My version of the balsamic glazed carrots is similar: toss the carrots with 2 T olive oil then roast in a 425 degree oven for 20 min or until carrots are done to taste. Coat carrots with 2 T balsamic vinegar and roast for 2-3 minutes or until vinegar has evaporated. I have found the addition of sugar to be unnecessary. I have passed this recipe to several people in the office and they all agree that it's terrific.  -  24 Feb 2003  (Review from Allrecipes USA and Canada)

The carrots had a wonderful flavor; however, the saute cooking method took a LOT longer than 10 minutes.....and that was with the carrots cut in half lengthwise. Next time, I plan to steam them, then I will finish them in a skillet with the balsamic vinegar and brown sugar.  -  10 Mar 2007  (Review from Allrecipes USA and Canada)

Wow...so simple & flavorful! My tweaks: par-steamed (2 min) then sauteed in a little butter and olive oil...maybe another 2-3 minutes...finished w/equal amounts of brown sugar & good balsamic. Exquisite! Thank You!  -  10 Jan 2007  (Review from Allrecipes USA and Canada)
