I made these a long time ago when I had a bunch of people over. Lost the recipe so I'm very glad you posted it. Looking forward to making them again.
Have made this several times and it's a favourite way to prepare potatoes. Easily serves 4 because they're so good. I've baked this an extra 10 minutes with the temp down to 400F for the last 1/2 hour. Yukon Gold's are a good choice but most potatoes will work fine. Thin, thin slices work the best, lots of them, just keep layering. Thanks for posting.
