  1. Love the recipe, but I just kind of stir and chop the potatoes with a spoon so they are more like eating a baked potato than mashed.5 stars

  2. I’ve got mine in the oven now! I make it every couple of months – so yummy! Serving along side buffalo chicken wings and a salad.

    1. Yes, the recipe should be prepared up to step 3. and spread into a slow cooker instead of a casserole dish. You may need to double the recipe depending on the size of your slow cooker.

  3. Holly you were right! Thanks! I didn’t have oven space today for our family holiday so I made this in my 9×13 crockpot and it was amazing as usual. 3 hours on low.5 stars
