  • Total Time: 50 mins
  • Yield: 4-6 Servings 1x


  • 11/2 lbs red potatoes, skins on, washed and scrubbed

    We made these for Thanksgiving this year and they were a hit. Fairly simple, very tasty, and they were great with or without gravy! Thanks for the recipe.

    Nice upgrades here from plain old mashed potatoes. I like the idea of the buttermilk and the fresh herbs are certainly welcome. And yet it’s lighter than the mashed potatoes loaded with whole cream that a lot of people serve on Thanksgiving. Should be a good one for Christmas dinner, too!
