Potato Salad Recipe With Mustard And Mayo: Classic Creamy Side With Tangy Kick

There’s a reason this potato salad keeps appearing at every family gathering I attend. The balance of creamy mayo and sharp mustard creates a dressing that’s rich yet bright, coating every tender potato perfectly.

I learned early that the secret lies in the details—waxy potatoes hold their shape, a touch of vinegar keeps the flavors vibrant, and chilling time lets everything meld. This version stays true to the classic while feeling anything but ordinary.

What results is a side dish with satisfying texture contrast: soft potatoes, crisp celery, and a dressing that clings without being heavy. It’s the kind of recipe that earns second helpings before the main course is even served.

Serve it warm or cold—both ways deliver that perfect tangy kick.

Ingredients for Potato Salad Recipe with Mustard and Mayo

Waxy potatoes, tangy dressing, classic ingredients that feel anything but ordinary.

The potatoes make this. Yukon Golds or red potatoes hold their shape best—avoid Russets, they turn to mush. I grab mine from Trader Joe’s or the local farmers market when they’re in season. For the mayo, Hellmann’s or Duke’s are my go-tos (full-fat only, don’t skimp). The mustard should be classic yellow, but I always keep a jar of French’s on hand for that sharp kick.

No dill pickles? Sweet pickles at half the amount work, but you’ll lose some tang. Fresh dill is ideal, but dried dill at one-third the amount gets you close. The celery adds crunch—if you hate it, try bell pepper or radishes. Want more zing? Add an extra tablespoon of vinegar or a pinch of cayenne (just don’t tell my grandma).

This tastes even better after a night in the fridge. Keeps 4-5 days covered in the fridge. Don’t freeze it though—mayo separates and potatoes get watery. Perfect for potlucks (or midnight snacks).

Step-by-Step Instructions for Potato Salad With Mustard and Mayo

Here’s how I make this classic side—simple steps, perfect texture, every time.

Step 1: Cook and Cool the Red Potatoes

Place the 2 lb Red Potatoes in a large pot and cover with cold water by 1 inch. Add 1 tsp Salt to the water. Bring to a boil over high heat, then reduce to medium and simmer for 12-15 minutes until a knife slides in easily but the potatoes still have some bite.

Drain immediately and let cool for 5 minutes. You want them warm but not hot when you mix in the dressing—this helps them absorb the flavors better. Cut them into 1-inch cubes while still warm, leaving the skins on for texture and color.

Step 2: Prepare the Vegetables and Eggs

While the potatoes cook, finely dice the 3 whole Celery Stalks and 0.5 whole Red Onion. I like to soak the diced red onion in cold water for 5 minutes to mellow its sharpness, then drain well before adding.

Chop the 0.5 cup Dill Pickles into small pieces and peel and chop the 4 whole Hard-Boiled Eggs. Chop the 2 tbsp Fresh Dill as well. Having everything prepped and ready means you can mix the salad while the potatoes are still warm.

Step 3: Make the Creamy Mustard-Mayo Dressing

In a large bowl, whisk together the 0.75 cup Mayonnaise, 2 tbsp Yellow Mustard, 1 tsp Dijon Mustard, 1 tbsp White Vinegar, 0.5 tsp Black Pepper, and 0.5 tsp Sweet Paprika. The vinegar brightens the richness of the mayonnaise, while the two mustards add depth and tang.

This is where the magic happens—the combination of full-fat mayonnaise and both mustards creates that classic creamy texture with a slight kick. Whisk until completely smooth, with no streaks of mustard visible.

Step 4: Combine Everything Gently

Add the warm cubed potatoes to the dressing and fold gently with a spatula to coat evenly. Then add the diced celery, red onion, dill pickles, hard-boiled eggs, and fresh dill. Fold again until everything is well distributed.

Real talk: don’t overmix here. You want the potatoes to stay intact and the eggs to remain in visible chunks. The dressing should cling to every piece without turning the salad into a mushy mess.

Step 5: Chill and Let Flavors Meld

Cover the bowl with plastic wrap and refrigerate for at least 1 hour (I prefer 2 hours if possible). This chilling time allows the flavors to meld together and the dressing to thicken slightly as it absorbs into the potatoes.

Before serving, give it one final gentle stir and adjust seasoning if needed. The paprika adds a subtle warmth and a beautiful color contrast against the creamy dressing and green dill. Serve chilled for the best texture and flavor.

Troubleshooting Perfect Results

Dressing Too Thin

If your dressing seems runny, you likely added too much pickle juice or vinegar. Fix it by whisking in an extra 2-3 tbsp mayonnaise until creamy. I always start with less liquid and adjust—easier to thicken than thin. 💡

Watery Salad

Watery results usually mean the potatoes weren’t drained well. Pat them dry with a towel after boiling. If already mixed, add 1-2 tbsp instant mashed potato flakes to absorb excess moisture without changing flavor.

Potatoes Falling Apart

Overcooking or overmixing causes mushy potatoes. Boil until just tender (12-15 minutes), then fold gently with a spatula. Use waxy potatoes like red or Yukon Gold—they hold shape better than Russets.

Dressing Separates

If the dressing looks greasy or separated, whisk in 1 tsp hot water to re-emulsify. This trick works wonders with mayonnaise-based dressings. Always store leftovers in an airtight container to prevent separation.

Bland Flavor

Taste and adjust seasoning. Add ½ tsp salt, ¼ tsp black pepper, or 1 tsp vinegar for brightness. I often add an extra 1 tsp Dijon mustard for depth. Remember, flavors meld more after chilling. 🌟

Eggs Too Dry

Hard-boiled eggs can turn rubbery if overcooked. Boil for exactly 9-10 minutes, then shock in ice water. Chop just before adding to the salad to retain moisture. Fresh eggs peel easier than older ones.
