Perfect for those of us with a passion for potatoes and oven meals! Actually have made this twice within the last week -first time exactly as posted and everything was fine but the second time I cranked up the oven to 400 for last 30 so I could roast some corn in oven at SAME time and that worked out fine. I used rosemary with the oregano which my photo shows. Thanks lazyme for posting. Made for Potato event in Photo Forum.
