This mashed potato salad is a delightful twist on the classic potato salad, combining the creamy texture of mashed potatoes with the tangy flavors of mayonnaise, sour cream, and dijon mustard. It's perfect for picnics, barbecues, or as a comforting side dish for any meal.
While most of the ingredients for this recipe are common pantry staples, you might need to pick up dijon mustard and chives if they are not already in your kitchen. Dijon mustard adds a unique tangy flavor, and chives provide a fresh, mild onion taste that complements the creamy potatoes perfectly.

Ingredients for Mashed Potato Salad Recipe
Potatoes: The base of the salad, providing a creamy and starchy texture.
Mayonnaise: Adds creaminess and a rich flavor to the salad.
Sour cream: Contributes a tangy taste and smooth texture.
Dijon mustard: Provides a sharp, tangy flavor that enhances the overall taste.
Salt: Essential for seasoning and bringing out the flavors of the other ingredients.

Technique Tip for This Recipe
When boiling the potatoes, make sure to start them in cold, salted water. This ensures that they cook evenly from the inside out. Once the water reaches a boil, reduce the heat to a simmer to prevent the potatoes from breaking apart. After draining, let the potatoes cool slightly before mashing to achieve a smoother texture. For an extra creamy mashed potato salad, use a potato ricer or food mill instead of a traditional masher.

Store the container in the refrigerator. The mashed potato salad can be kept for up to 3-4 days. Always check for any signs of spoilage before consuming.
For freezing, portion the mashed potato salad into smaller, individual servings. This makes it easier to thaw only what you need.
Place each portion into a freezer-safe container or a resealable freezer bag. Squeeze out as much air as possible to prevent freezer burn.
Label the containers or bags with the date. This helps you keep track of how long the mashed potato salad has been stored.
Freeze the mashed potato salad for up to 1 month. While it can be frozen longer, the texture and flavor may start to degrade.
To thaw, transfer the desired portion from the freezer to the refrigerator. Allow it to thaw slowly overnight for the best texture.
Once thawed, give the mashed potato salad a good stir to reincorporate any separated ingredients. You may need to add a bit more mayonnaise or sour cream to restore its creamy consistency.
Avoid refreezing the mashed potato salad once it has been thawed. This can negatively affect the texture and flavor.
How To Reheat Leftovers
For a quick and easy method, use the microwave. Place the mashed potato salad in a microwave-safe dish, cover it with a damp paper towel to retain moisture, and heat on medium power for 1-2 minutes. Stir halfway through to ensure even heating.

For a more gourmet touch, use the oven. Preheat your oven to 350°F (175°C). Spread the mashed potato salad in an oven-safe dish, cover with aluminum foil, and bake for 15-20 minutes or until heated thoroughly. For a crispy top, remove the foil during the last 5 minutes of baking.
If you have a steamer, place the mashed potato salad in a heatproof bowl and set it in the steamer basket. Steam for about 5-7 minutes or until hot, stirring occasionally to ensure even heating.
For those who enjoy a bit of a twist, consider reheating the mashed potato salad in an air fryer. Preheat the air fryer to 350°F (175°C), place the mashed potato salad in an air fryer-safe dish, and heat for 5-7 minutes, stirring halfway through for even warmth.
