It won't come out the same, but it can still be good. I find it helpful to thaw the veggies first (in the microwave, usually) and then put in a strainer for about 10 minutes or so, and then blot dry. Otherwise, the veggies just seem to steam rather than roast. I also often increase the temp by about 25 degrees and/or cook them longer.
