According to a study which was published in the Journal of Agricultural and Food Chemistry, carrots do not lose their nutritional value when cooked. In fact, cooked carrots had higher antioxidant values when cooked than raw.
I prefer carrots cooked because they can taste sweeter. A couple of nights ago, I bought a 2 lb bag of baby carrots. I tossed them with 4 teaspoons of olive oil, a tablespoon of finely minced fresh thyme and sage, and spread them in my roasting pan. I then drizzled them with juice from a wedge of orange (about 2 tablespoons). I baked them at 400 for about 30 minutes until they just started to shrivel and caramelize, and were fork tender. They were so good! It brought out the natural sugars so they tasted as if they were cooked in honey, but I hadn't added any sugar. I had a large batch, so I froze them in individual portions so I could just reach in the freezer and find a serving of vegetables that I loved.
If divided into 6 servings, each serving contained 87 calories, 4 grams fat, 3 grams fiber, 13 carbs, 1/3 of your daily Vit C, and 2 or 3 times your daily requirement of Vitamin A.
How do you like your carrots?
