Name: Dill and Dijon Potato Salad
Prep time: 20 min
Cook time: 15 min
Total time: 35 min
Ingredients: 2 pounds baby yellow potatoes, scrubbed and halved; 1/3 cup mayonnaise; 3 tablespoons Dijon mustard; 2 tablespoons olive oil; 2 tablespoons apple cider vinegar; 2 tablespoons fresh dill, finely chopped; 3 tablespoons red onion, finely diced; 1 teaspoon garlic, minced; 1 teaspoon salt; 1/2 teaspoon black pepper; 1 teaspoon whole‑grain mustard

Dill and Dijon Potato Salad tastes tangy, herby, creamy, and just a little sharp from the mustard, like classic picnic potato salad with a zippy upgrade. It works for busy home cooks who want a make-ahead side dish in about 35 minutes that still feels a bit special. I first tested this version for a neighborhood cookout and watched the bowl empty before the burgers even cooled.

Why Dill and Dijon Potato Salad Is Worth It

Dill and Dijon Potato Salad brings together tender potatoes, bright fresh dill, and a punchy Dijon dressing that cuts through the richness. The flavor hits that perfect spot between creamy and sharp, so it never tastes heavy or boring.

You can prep it ahead, chill it, and pull it out when guests walk in or when dinner needs a quick side. It travels well, holds up on a buffet, and tastes even better after the flavors mingle in the fridge.

Ingredients You Need

Potatoes

2 pounds small yellow or Yukon Gold potatoes, scrubbed
1 teaspoon fine sea salt for the cooking water

Creamy Dijon dressing

1/3 cup mayonnaise (use your favorite brand; I like Hellmann’s or Duke’s)
3 tablespoons Dijon mustard (smooth style; use grainy Dijon for more texture)
2 tablespoons sour cream or plain Greek yogurt
2 tablespoons extra virgin olive oil
2 tablespoons fresh lemon juice or white wine vinegar
1 teaspoon honey or sugar, to balance the acidity
1 to 1 1/4 teaspoons fine sea salt, to taste
1/2 teaspoon black pepper, freshly ground

Herbs and mix ins

1/3 cup fresh dill, finely chopped, tender stems included
3 green onions, thinly sliced (white and green parts)
1/3 cup finely diced celery, for crunch
2 tablespoons finely diced red onion, for extra bite
1 small garlic clove, very finely minced or grated
Optional: 2 hard boiled eggs, chopped, for a more classic deli vibe
Optional: 1 tablespoon capers, drained, for briny pops of flavor

Pantry shortcuts and swaps

Use dried dill in a pinch: 1 to 1 1/2 teaspoons, added to the dressing so it softens.
Use yellow mustard if Dijon ran out; the flavor turns milder and a bit sweeter.
Use all mayonnaise if you do not keep sour cream or yogurt.
Use pre chopped onions and celery from the produce section to save time.

Equipment list

Large pot for boiling potatoes
Colander
Cutting board and sharp knife
Large mixing bowl
Small bowl or jar for whisking the dressing
Rubber spatula or large spoon for folding everything together

Quick Tips & substitutions

Cut potatoes into equal size chunks so they cook at the same rate.
Start potatoes in cold, salted water so they cook evenly and season from the inside.
Dress potatoes while still warm so they soak up more flavor.
Chill the salad at least 30 minutes before serving for best texture and taste.
Use Greek yogurt instead of sour cream for extra protein and a tangier bite.
Swap green onions with chives or finely minced red onion if needed.
Use dried dill only if fresh dill stays unavailable; use less, since dried tastes stronger.
Skip eggs for a lighter feel or add them for a more old school deli style.
Use vegan mayo and plant based yogurt for a dairy free, egg free version.
Add a spoonful of whole grain mustard if you want visible mustard seeds and extra tang.

How to Make Dill and Dijon Potato Salad

Step 1: Prep and cook the potatoes

Scrub the potatoes and cut them into bite size chunks, about 1 inch pieces. Place them in a large pot and cover with cold water by about 1 inch, then stir in 1 teaspoon of salt.

Bring the pot to a gentle boil over medium high heat, then lower the heat so the water simmers. Cook the potatoes 10 to 15 minutes, until a fork slides in easily but the pieces still hold their shape.

Drain the potatoes in a colander and let them steam off for 5 minutes so excess moisture escapes. Spread them out slightly in the colander or on a sheet pan so they cool faster but still stay warm for dressing.

Step 2: Mix the Dill and Dijon dressing

While the potatoes cook, whisk the mayonnaise, Dijon mustard, sour cream or yogurt, olive oil, and lemon juice in a small bowl. Add the honey, 1 teaspoon salt, black pepper, and minced garlic, then whisk again until smooth and creamy.

Taste the dressing and adjust the seasoning with more salt, pepper, or lemon juice as needed. The dressing should taste slightly stronger than you want the final salad, since the potatoes will mellow it out.

Step 3: Prep the herbs and crunchy bits

Chop the fresh dill finely so it spreads evenly through the salad. Slice the green onions thinly and dice the celery and red onion into small pieces so they add crunch without big harsh bites.

If you use eggs, peel and chop them into small chunks. If you use capers, drain them well and pat them dry with a paper towel so they do not water down the dressing.

Step 4: Dress the warm potatoes

Transfer the warm potatoes to a large mixing bowl. Pour about two thirds of the dressing over the potatoes and gently fold with a spatula so you coat every piece without smashing them.

Let the dressed potatoes sit for 5 to 10 minutes so they absorb the flavors. If they look dry, add more dressing a spoonful at a time until the salad looks creamy but not soupy.

Step 5: Add dill, onions, and extras

Add the chopped dill, green onions, celery, red onion, eggs if using, and capers if using. Fold gently until everything distributes evenly through the salad.

Taste again and adjust with a pinch of salt, extra dill, or a squeeze of lemon juice. The salad should taste bright, herby, and tangy with a creamy finish.

Step 6: Chill and serve

Cover the bowl and chill the Dill and Dijon Potato Salad for at least 30 minutes, or up to 24 hours. The flavors blend as it rests, and the texture firms up a bit.

Right before serving, give it a gentle stir and add a sprinkle of fresh dill and black pepper on top for a fresh look. Serve cold or at cool room temperature.

Recipe Variations

Gluten free: The base recipe already fits gluten free needs; just check labels on mustard and mayo.
Vegan: Use vegan mayonnaise and plant based yogurt, skip eggs, and keep the rest the same.
Low carb style: Swap half the potatoes with steamed cauliflower florets to cut carbs while keeping a similar feel.
Extra protein: Add chopped grilled chicken or canned chickpeas, drained and rinsed.
More crunch: Stir in diced cucumber, radishes, or extra celery right before serving.
Smoky twist: Add a pinch of smoked paprika or a spoonful of chopped roasted red peppers.
Herb swap: Mix dill with parsley, chives, or tarragon for a different herbal profile.

Ways to Serve

Pair with grilled chicken, turkey burgers, or veggie burgers.
Spoon next to baked salmon or roasted white fish.
Pack into lunch boxes with sliced cucumbers, cherry tomatoes, and fruit.
Serve at potlucks, picnics, or family cookouts as a make ahead side.
Use leftovers as a base and top with canned tuna or chickpeas for a quick lunch bowl.

Storage Success

Store Dill and Dijon Potato Salad in an airtight container in the fridge for up to 4 days. Stir before serving, since the dressing can settle slightly as it chills. If the salad looks a bit thick after a day or two, loosen it with a small splash of lemon juice or a spoonful of mayo or yogurt. Keep it chilled until serving time, and discard any portion that sat out at room temperature longer than 2 hours.
