OK - so I did a test run on roasting carrots & parsnips for Thanksgiving dinner. Sliced them and tossed with olive oil & rosemary and baked (covered) for about 30 minutes @ 350. Not only did they burn on the bottom, but they were also very dried out. I wouldn't think that 30 minutes would be too long for them to bake. Thinking maybe baking them at a lower temp?? Anyone have any suggestions?
