Mashed Potato Salad Ingredients
POTATOES Any kind of mashed potatoes will do! Even if they are already seasoned (Garlic Roasted or Parmesan), it will add to the flavor of the salad.
ADD-INS We added celery and hard-boiled eggs for texture but you can add bacon bits, or even diced red apples or radishes for a sweet crunch that goes well with vinegar dressing.
VARIATIONS Diced red, yellow, green, or orange bell peppers will add color and crunch! Make this recipe with sour cream or switch it out for Greek yogurt. So many possibilities!
How To Make Mashed Potato Salad
This is the easy part! Just whisk the dressing, combine the ingredients, and chill!
- Whisk dressing ingredients together separately.
- Fold remaining ingredients into mashed potatoes & mix dressing in.
- Chill one hour before serving.
NOTE: You may not need all of the dressing. Add more or less, according to personal preference. Keep in mind, as the salad sits it will absorb some of the dressing.
What to Serve it With
Burgers of course!
This is the perfect side salad to serve with a Baked Ham with Brown Sugar Glaze, or an Easy Rotisserie Chicken. It’s also super tasty with French Dip Sandwiches. It’s an elegant and easy salad for any occasion! Scoop it on top of a bed of greens or add into an Easy Chicken Lettuce Wrap for a school or workday lunch.
Recipe Tips
- No leftover mashed potatoes? Use leftover roasted potatoes and give them a little squish with a masher.
- Make hard-boiled eggs the day before and keep them in the refrigerator until they are ready to use (the air fryer is the easiest way to do this). This will help keep the salad cold!
- Make an extra batch of the dressing, it’s great on macaroni salad too!
- The dressing will keep in the refrigerator for up to 2 weeks in a salad dressing cruet or mason jar.

I used instant mashed potatoes since I didn’t have any fresh potatoes or leftover mashed potatoes. Turned out delish.
I made up boxed instant potatoes, since i didn’t have any fresh potatoes. Turned out delish.
I made this as directed except…
I substituted coursely chopped baked potatoes for the hardboiled eggs. I’m one of those people who thinks eggs have no business in potato salad. Came out great.
Everyone loves this, they loved my other potato salad but this one is better , plus it’s the next day use for the mashed, so good with the flavor you put in the mashed!!! Only one I’m making now!
So glad everyone loved it JP!
So simple and delicious. Now I will be making extra mashed potatoes so I can have this potato salad.
I support that idea, Patricia! This salad is so delicious.
Great recipe, although I did tweak it a bit to fit my liking. It revived my mashed potatoes and is delish!
So happy you enjoyed this recipe Darbi!
Absolutely delicious as written
Genius! I never thought of using leftover mashed potatoes for salad but this sounds delish.
Mashed Potatoes Salad is the only type of Potato Salad I will eat. I don’t like chunkier Potato Salad!
I like it with:
boiled eggs chopped up
Onions chopped up
Sweet pickles chopped up
kosher dills chopped up
(My grandmother put chopped celery)
Mustard
Real Kraft Mayonnaise
Salt and pepper
A little vinegar
I also boil my eggs with the Potatoes to save time. I use a pastry blender to blend in the eggs(chopped).
I LOVE MASHED POTATO SALAD!
I forget to mention that I do add butter…
