Dill and Dijon Potato Salad tastes creamy, tangy, and bright with fresh herbs, and it suits anyone who loves classic comfort food with a little zip in under 45 minutes. It works well for picnics, potlucks, or weeknight dinners when you want something that feels homemade without a ton of fuss. I first made this version for a backyard cookout in my tiny apartment years ago, and it still disappears before the burgers.

Why Make This Dill and Dijon Potato Salad at Home

Homemade Dill and Dijon Potato Salad gives you control over texture, seasoning, and how bold you want that Dijon kick. You choose how much dill, how creamy the dressing, and whether you like your potatoes super tender or with a little bite.

You also skip the gloopy, overly sweet deli case versions that taste the same no matter where you buy them. This version tastes bright, herby, and balanced, and it holds up well in the fridge for easy leftovers.

“This Dill and Dijon Potato Salad tastes like the best parts of a deli classic with way more flavor, freshness, and zero soggy sadness.”

Ingredients You Need

Potatoes

2 pounds small yellow or Yukon Gold potatoes, scrubbed
- Yellow potatoes hold their shape and stay creamy.
- You can use red potatoes if that is what you have, but avoid starchy russets because they fall apart too easily.

Dressing

1/3 cup mayonnaise
- Use a full-fat mayo for the best texture.
- Avocado oil mayo or a good classic American brand both work well.
3 tablespoons Dijon mustard
- Choose a smooth Dijon, not whole grain, for a silky dressing.
- If you like extra heat, add 1 more teaspoon.
2 tablespoons Greek yogurt or sour cream
- This lightens the dressing and adds tang.
2 tablespoons apple cider vinegar or white wine vinegar
1 tablespoon fresh lemon juice
1 to 1 1/2 teaspoons kosher salt, plus more to taste
1/2 teaspoon black pepper
1 teaspoon sugar or honey
- This tiny bit of sweetness balances the vinegar and mustard.
2 to 3 tablespoons extra virgin olive oil
- Whisk this in to loosen the dressing and add richness.

Herbs and Mix-ins

1/3 to 1/2 cup fresh dill, finely chopped
- Use the tender fronds and thin stems.
2 tablespoons finely chopped fresh parsley (optional but nice)
3 green onions, thinly sliced
1/3 cup finely diced red onion or shallot
2 ribs celery, finely diced
2 hard boiled eggs, chopped (optional, for a more classic deli vibe)
1 tablespoon capers, drained and chopped (optional, for extra tang)
1 small dill pickle, finely chopped, or 2 tablespoons relish (optional, for crunch and acidity)

Pantry shortcuts and substitutions

Use pre-cooked refrigerated potatoes if you want to skip boiling, but toss them gently so they do not break.
Use dried dill only if you have no fresh herbs at all, and use just 1 to 2 teaspoons since dried herbs taste stronger.
Swap Greek yogurt for all of the mayo if you want a lighter Dill and Dijon Potato Salad, but add a bit more olive oil for creaminess.
Use yellow mustard if you dislike Dijon, but expect a milder flavor.

Equipment

Large pot for boiling potatoes
Colander
Large mixing bowl
Small bowl and whisk for the dressing
Cutting board and sharp knife
Rubber spatula or large spoon for gentle mixing

Tips & Mistakes

Cut potatoes into even chunks so they cook at the same rate.
Salt the cooking water generously so the potatoes taste seasoned from the inside out.
Boil potatoes until just fork tender; stop before they crumble.
Drain potatoes well so extra water does not thin the dressing.
Toss warm potatoes with a little vinegar and salt before the full dressing to boost flavor.
Chill the dressing while potatoes cook so flavors meld.
Fold the salad gently so you keep some potato chunks instead of mashed potatoes.
Taste and adjust salt, pepper, and acid after chilling because flavors mellow in the fridge.
Add fresh dill near the end so it stays bright and green.
Keep the salad cold at picnics and potlucks; do not let it sit at room temperature for hours.

How to Make Dill and Dijon Potato Salad

Step 1: Cook the potatoes

Scrub the potatoes and cut them into bite-size chunks, about 1 to 1 1/2 inches. Add them to a large pot and cover with cold water by about 1 inch, then stir in 1 to 2 tablespoons of kosher salt. Bring the pot to a gentle boil over medium heat and cook until the potatoes feel just tender when you pierce them with a fork, about 10 to 15 minutes.

Drain the potatoes in a colander and let them steam off for a few minutes so excess moisture escapes. While they still feel warm, sprinkle them with 1 tablespoon vinegar and a pinch of salt, then toss gently. This step seasons the potatoes and helps them soak in flavor.

Step 2: Mix the dressing

In a small bowl, whisk together mayonnaise, Dijon mustard, Greek yogurt or sour cream, remaining vinegar, lemon juice, sugar or honey, salt, and pepper. Stream in the olive oil while you whisk until the dressing looks smooth and slightly thick but pourable. Taste and adjust seasoning so it tastes tangy, a bit salty, and slightly sharp from the mustard.

Chill the dressing in the fridge while you prep the mix-ins. This short rest helps the flavors blend and gives the dressing a better texture.

Step 3: Prep herbs and crunchy bits

Finely chop the dill and parsley. Slice the green onions, dice the red onion or shallot, and chop the celery. If you use eggs, capers, or pickles, chop those into small pieces so they tuck into the salad instead of taking over each bite.

Add all these mix-ins to a large mixing bowl. This step keeps everything ready so you can assemble the Dill and Dijon Potato Salad while the potatoes still feel slightly warm.

Step 4: Combine potatoes and dressing

Add the warm potatoes to the bowl with the herbs and vegetables. Pour about two thirds of the dressing over the top. Use a rubber spatula to fold everything together gently until the potatoes look coated and the herbs spread evenly.

Taste a piece of potato and adjust with more dressing, salt, or pepper as needed. If the salad looks dry, add a splash of olive oil or a spoonful of mayo instead of thinning it with water.

Step 5: Chill and serve

Cover the bowl and chill the Dill and Dijon Potato Salad for at least 30 minutes, and up to a few hours, so the flavors meld. Right before serving, give it a gentle stir and taste again. Add a sprinkle of fresh dill or green onion on top for color and a fresh aroma.

Variations I've Tried

Extra herby version
Double the dill and parsley and add a handful of chopped chives. This version tastes bright and fresh and works well with grilled chicken or fish.
No mayo version
Use all Greek yogurt plus olive oil and a bit more Dijon. The salad tastes lighter and tangier, and it still feels creamy enough for most mayo lovers.
Bacon and dill version
Crisp a few slices of bacon, crumble them, and fold them in with the herbs. The smoky flavor pairs nicely with the sharp Dijon and fresh dill.
Pickle lover version
Add extra chopped dill pickles or relish and a spoonful of pickle brine. This version tastes punchy and tangy and works well for anyone who loves pickles in their potato salad.
Vegan version
Use vegan mayo, skip the eggs, and keep the Dijon and dill as written. The texture stays creamy, and the flavor stays bold and herby.

How to Serve Dill and Dijon Potato Salad

Serve Dill and Dijon Potato Salad chilled or at cool room temperature alongside grilled chicken, burgers, sausages, or veggie skewers. Spoon it into lettuce cups for a lighter option, or pile it into a bowl with sliced cucumbers and tomatoes for a picnic plate. Pack it in lunch boxes with sliced fruit and a simple green salad for a complete meal. If you host a cookout, set it out with other sides like coleslaw and corn on the cob so everyone can build their own plate.

How to store

Store Dill and Dijon Potato Salad in an airtight container in the fridge for up to 4 days.
Stir before serving leftovers and adjust with a squeeze of lemon or a spoonful of Dijon if the flavor tastes muted.
Avoid freezing, since the potatoes and dressing change texture and turn grainy.
Serve leftovers cold or let them sit at room temperature for 10 to 15 minutes; skip reheating, because heat can split the dressing.
