What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, but they come together in a way that’s anything but basic.

• Potatoes: 2 pounds (900g) Yukon Gold or red potatoes, scrubbed and cut into bite-sized chunks (these hold their shape best)
• Mayonnaise: 3/4 cup (180ml) – I recommend Hellmann’s for the best creamy texture
• Dijon Mustard: 2 tablespoons (30ml) – the star ingredient for that perfect tang
• Yellow Mustard: 1 tablespoon (15ml) – adds a mild sharpness to balance the Dijon
• Celery: 2 stalks, finely chopped (for crunch and freshness)
• Red Onion: 1 small, finely diced (adds a subtle bite)
• Sweet Pickles: 1/3 cup (80ml), diced (adds a touch of sweetness and texture)
• Apple Cider Vinegar: 1 tablespoon (15ml) – brightens the flavors
• Salt: 1 teaspoon (to taste)
• Black Pepper: 1/2 teaspoon (freshly ground for best flavor)
• Hard-Boiled Eggs: 2 large, chopped (optional, but adds richness and tradition)
• Fresh Parsley: 2 tablespoons, chopped (for garnish and a hint of herbaceous freshness)

If you need a gluten-free option, this recipe suits perfectly without any changes. For a dairy-free version, use a mayo brand without dairy. During summer, I sometimes swap sweet pickles for chopped fresh cucumbers for a lighter crunch—a little twist that keeps things interesting.

Equipment Needed

• Large Pot: For boiling the potatoes. A heavy-bottomed pot helps distribute heat evenly.
• Colander: To drain the potatoes thoroughly after boiling.
• Mixing Bowl: A large bowl to combine all ingredients comfortably.
• Sharp Knife and Cutting Board: For chopping veggies and eggs precisely.
• Measuring Cups and Spoons: For exact ingredient amounts.
• Spatula or Wooden Spoon: To gently fold the salad without mashing the potatoes.

If you don’t have a large pot, a deep skillet with a lid works in a pinch. For budget-friendly options, you can use plastic mixing bowls, but glass or stainless steel keeps things cooler and easier to clean. Personally, I keep a dedicated sharp paring knife just for chopping small veggies—it makes the prep smoother and safer.

Preparation Method

1. Prep the Potatoes: Place the potato chunks in a large pot and cover with cold water by about an inch (2.5 cm). Add a pinch of salt. Bring to a boil over medium-high heat, then reduce to a simmer. Cook until the potatoes are fork-tender but not falling apart—about 15-18 minutes. (You want potatoes that hold their shape; overcooked ones turn mushy.)
2. Drain and Cool: Drain the potatoes in a colander and rinse with cold water to stop cooking. Let them cool completely—this prevents the mayo from breaking down and keeps the salad creamy.
3. Chop the Add-ins: While potatoes are cooling, finely dice the celery, red onion, and sweet pickles. If you’re using hard-boiled eggs, chop those up too.
4. Mix the Dressing: In a large mixing bowl, whisk together the mayonnaise, Dijon mustard, yellow mustard, apple cider vinegar, salt, and pepper.
5. Combine Everything: Gently fold the cooled potatoes, chopped veggies, and eggs into the dressing. Stir carefully so you don’t mash the potatoes but everything gets evenly coated.
6. Adjust Seasoning: Taste and add more salt, pepper, or vinegar if needed. The flavors should be balanced—creamy with a tangy kick.
7. Chill Before Serving: Cover and refrigerate for at least 1 hour to let the flavors meld. (Honestly, it tastes even better the next day.)
8. Garnish and Serve: Just before serving, sprinkle chopped fresh parsley on top for color and freshness.

Pro tip: If you’re short on time, you can cool the potatoes faster by spreading them out on a baking sheet in the fridge. Also, don’t skip the vinegar—it’s what brings the mustard’s tang into harmony with the creamy mayo.

Cooking Tips & Techniques

Making this creamy classic potato salad with mustard is simple, but a few tricks can make the difference between good and great.

• Choose the Right Potato: Waxy potatoes like Yukon Gold or red potatoes hold their shape beautifully, avoiding a mushy mess.
• Cook Potatoes Gently: Boiling too rapidly can cause potatoes to break apart. Keep it at a gentle simmer.
• Cool Potatoes Before Mixing: Hot potatoes can make mayonnaise separate, resulting in a runny salad. Cooling them fully is key.
• Mustard Balance: Using both Dijon and yellow mustard provides depth without overpowering. Feel free to adjust the ratio to your taste.
• Don’t Overmix: Gently folding ingredients prevents potatoes from breaking up and keeps the texture appealing.
• Chill Long Enough: Letting the salad rest in the fridge for at least an hour lets the flavors marry perfectly.

One cooking fail I learned from? Adding chopped onions too early made the salad soggy and bitter. Now, I add them just before chilling to keep that fresh crunch. Also, keep an eye on salt—you can always add more later, but it’s tricky to fix an overly salty salad.

Variations & Adaptations

This creamy classic potato salad with mustard is flexible and can take on a few tasty twists depending on your mood or dietary needs.

• Vegan Version: Swap mayonnaise for vegan mayo and skip the eggs. Add diced avocado for creaminess.
• Low-Carb Twist: Replace half the potatoes with cauliflower florets for a lighter salad.
• Spicy Kick: Add a teaspoon of hot sauce or a pinch of cayenne pepper to the dressing for heat.
• Herb-Infused: Mix in fresh dill or chives for a bright herbal note.
• Seasonal Spin: During summer, toss in fresh chopped cucumbers or green beans to add crunch and freshness.

Personally, I tried the low-carb twist once for a family barbecue—nobody guessed cauliflower was hiding in there, and it was a hit! Feel free to play around with flavors until you find your perfect match.

Serving & Storage Suggestions

This creamy classic potato salad with mustard is best served chilled or at cool room temperature. It pairs wonderfully with grilled meats, sandwiches, or as part of a picnic spread.

• Serving: Garnish with fresh parsley or a sprinkle of paprika for color. Serve alongside BBQ ribs, fried chicken, or veggie burgers.
• Storage: Store in an airtight container in the refrigerator for up to 3 days. The flavors deepen over time, making leftovers even more delicious.
• Reheating: Potato salad is traditionally served cold, but if you want it slightly warmer, let it sit at room temperature for 20 minutes before serving.

Pro tip: Avoid freezing this salad—it can change texture and make the mayo separate. If you want to prep ahead, keep the dressing separate and mix just before serving.
