    if I wanted to add prepared horseradish sauce to this recipe, how much would you recommend?

    1. Robyn Stone says:

      Hi Colleen,
      When I add prepared horseradish to my mashed potatoes, I add about two-three tablespoons, depending on taste.

    Made this for Christmas dinner with the roaster garlic & it was DIVINE! Hands down BEST mashed potatoes I have ever made! Absolutely in love! Thank you for the wonderful recipes!

    Thanks for another way of preparing a mashed potato recipe. I am thinking on how to do it for more grown up taste since the usual mashed potatoes caters the kids taste buds:-). Mashed potatoes add savor and goodness as a side dish. What do you mean by 3/4 cup half and half?

  4. Brenda @ a farmgirl's dabbles says:

    Oh, fabulous! I love roasted garlic. And mashed potatoes. I usually use 1 bulb of garlic with that many potatoes…looks like I need to try yours with 2!

  5. JulieD says:

    I completely agree…life wouldn’t be the same without them!! Yours looks divine!

    That sounds pretty heavenly, pure comfort.
