For Christmas this year I wanted to do a lot of the cooking ahead of time so I could enjoy the day. I also wanted to save some oven space. I found this recipe on line....you may have made variations of this .....and I only made slight changes.
I used 8 pounds of potatoes instead of 5, but didn't increase the amounts of the other ingredients. I did stir in about 3/4 cup of half and half during the last 30 minutes of the crockpot time. My mashed potato loving grandkids loved it so much they asked to take some home...and did!
