I read the recipe correctly and agree with all - 250 must be a typo. However-I found there was not enough milk to keep the casserole a casserole- it came out of the oven looking like potatoes and cheese. I added butter and more milk and put it back in the oven at 350. It's not finished yet-but I'm thinking 30 min.?
