Creamy, addictive Mashed Potato Salad is a game changer! Leftover mashed potatoes are the key ingredient that makes this the most requested at cookouts.

1 large bowl and 2 small bowls of potato salad, garnished with parsley leaves + blue napkin and spoons

This Mashed Potato Salad recipe is inspired by my dad, who made it for my family when I was a kid. He always called it "Hillbilly Potato Salad", so that's how we refer to it. Unlike our Red Potato Salad or Old Fashioned Potato Salad, this recipe is definitely non-traditional, but one bite and you will be converted. This is our GO-TO favorite Potato Salad recipe. I serve it at every cookout and summer holiday, because it tastes good with Grilled Ribeye Steak, Burgers, and all my grilling favorites.

Creamy Potato Salad

Unlike traditional potato salad, this recipe uses leftover mashed potatoes and simple ingredients you probably have in your pantry.
HINT: Make Creamy Mashed Potatoes as a side dish for your dinner, and be sure to make extra so you have leftovers to make this salad.

FAQ

What is mashed potato salad?

Mashed potato salad is a variation of traditional potato salad where the potatoes are mashed instead of diced. This results in a creamy texture, similar to mashed potatoes, combined with the flavors of a classic potato salad.

Should potato salad be served hot or cold?

We prefer this recipe served room temperature or cold. It provides and nice contrast to warm grilled meats, like burgers, steak or chicken.

What kind of potatoes are best for potato salad?

The potatoes you have! We like creamer potatoes, red skinned potatoes, or Yukon Gold potatoes for this recipe to give it great creamy texture.

Can mashed potato salad be made ahead of time?

Yes, mashed potato salad can be made ahead of time. It’s actually recommended to let it chill in the refrigerator for at least a few hours or overnight to allow the flavors to meld together.

    I will be making this tonight. My boys absolutely love this recipe.. Quite unique and incredibly delicious.. Thanks for sharing. Unfortunately, I don't have green onions. Hopefully a yellow onion will do.

    Oh my goodness! This absolutely made my day! My Dad also made this every spring & summer starting with Easter dinner and finishing for the year on Labor Day. We sadly lost him in 2010 and although we watched him many times, I just couldn’t seem to replicate his magic dish (although I’ve tried many times). THIS IS IT!!! I couldn’t shake my Easter craving for it so I once again searched the internet and boom! - your recipe popped right up. Strangely, my Dad was not the chef in the family but the couple of dishes he made were beyond amazing! Another strange coincidence, although we have been in Texas for 4 generations, our family too is originally from Glade Hollow, Virginia and I do know this was a handed down recipe. Wouldn’t it be cool to find that it absolutely is a Virginia mountain recipe?? I’ll keep researching. Thank you so much for sharing. It really felt like my Dad was right in my kitchen making this with me

      Sharon,
      You have made OUR day!!! What a wonderful story!! It warms our heart, especially during these times. We are so happy to have found a kindred spirit, united in love of this OUTSTANDING potato salad (we have on weekly rotation these days)! We absolutely must do some research to see where Keith's dad acquired the recipe. We will be back in touch! Thank you again so much for sharing. It means a lot.

    I gave this recipe a try, but it came out very salty. Hubby said it was "interesting"

    Does this actually use 3/4 mustard?

      Hi Karen,
      Thanks for stopping by! Yes, 3/4 cup mustard is correct. We like it with a strong mustard base (remember it serves 4-6 people). If you are worried, add a bit of mustard at a time to adjust to your taste. Please let us know how it turned out!
