Update: Thanksgiving 2006. I have made this casserole each year for Thanksgiving since 2002. Here are my comments from November 2002, totally unedited: I made this dish for my family's Thanksgiving Day feast. Dorothy, thanks for the suggestion you made in a thread discussing pros and cons of re-heating mashed potatoes! This was simply divine! This recipe proves beyond a doubt that reheating mashed potatoes CAN be done without any sacrifice in flavor! My son, who is a true traditionalist, told me that I could just plan on making these potatoes every single Thanksgiving from here on out! Not only were these potatoes creamy and tasty and beautiful to behold, but the pre-cooking of this casserole a day before Thanksgiving made my day so much easier! I advise anyone who believes you can not successfully re-heat mashed potatoes to try this one. And soon!

Dorothy, thank you so much for recommending this dish to me! It was perfect for the occassion! So easy to prepare and ready with a simple heating on the day needed. I will be using this recipe often from now on when I need to prepare for a crowd in advance. Thanks, Dorothy!
