Mashed Potatoes always draw me in. Especially gooooood mashed potatoes. You know what I mean, right? Those mashed potatoes that you can just tell someone took the time to make them right and didn’t just throw them together and hope for the best. The mashed potatoes that have just the right consistency, just the right amount of butter, just the right amount of salt, and oh yes, just the right amount of horseradish and garlic.

Yes, I said it. Horseradish and garlic.

I’ve always had a thing for mashed potatoes with horseradish and garlic and a couple of weeks ago when I ate at a beautiful restaurant while traveling, they served mashed potatoes with horseradish and I kept feeling like I wanted to tell them if they just added the garlic the mashed potatoes would have been perfect.

I think I have a problem.

Prep Time: 15 minutes
Cook Time: 45 minutes
Total Time: 1 hour
Servings: 12


  • 5 pounds Russet, or Yukon gold potatoes, peeled and cut into chunks
  • 1/2 cup butter, melted + 2 tablespoons cut into pieces
  • ¾ cup half and half
  • cloves from about 2 bulbs of roasted garlic
  • 2 tablespoons prepared horseradish
  • 1 teaspoon Kosher salt
  • teaspoons ground black pepper


  • Place potatoes into large saucepan and add enough water to cover, plus about 1 inch. Cook over medium-low heat until fork tender, about 15-20 minutes.
  • In a medium saucepan, melt butter, add half and half and roasted garlic. Heat until simmering.
  • Drain potatoes and pour potatoes back into saucepan used to cook them. Mash potatoes over low heat until smooth. Add the melted butter and half and half mixture to potatoes. Continue to mash the potatoes until creamy. Stir in prepared horseradish. Then, mix well with a wooden spoon until light, fluffy and smooth. Stir in salt and pepper.

Make-Ahead Tip: Prepare mashed potatoes and pour into a casserole dish. Cover tightly with aluminum foil or a lid and refrigerate until about 20 minutes before ready to serve. Then, place in a preheated oven at 350º F for 20 minutes.
When you remove from the oven, top with remaining 2 tablespoons of butter and a sprinkle of salt and pepper, if desired.

      Thanks, Katie. I, too, love these mashed potatoes with roasted chicken.

  2. Stephanie @ Girl Versus Dough says:

    I LOVE mashed potatoes and I love horseradish and garlic, but I’ve never thought of combining them. Need to try this ASAP!

  3. kelley says:

    Horseradish mashers are my favorite. I used to work in a game restaurant that served them and since then, I make them often. I’ve never added garlic as well but will definitely try it next time I make them! Hope you had a good time in Vegas!! xo

  4. Winnie says:

    I have made mashed potatoes with garlic (often) and with Horseradish (from time to time) so I can’t believe I never thought to do both at the same time. Thanks for sharing this, I will try this the next time I make mashed potatoes.

    I just had a baked potato yesterday with horseradish but not garlic. Need to get that garlic/horseradish combo going! YUM!
