This one’s a personal favorite of mine, made with fluffy russet potatoes, chopped eggs, creamy mayo, zesty mustard relish, and a good handful of fresh herbs straight from my garden. As a German immigrant, potatoes are practically in my DNA—I love them every which way and make no apologies for it.

This is the kind of potato salad that somehow tastes even better the next day (if there’s any left), and it’s flexible enough to work with whatever’s growing or hanging around in your kitchen. But the real magic? Those freshly snipped dill fronds, tender chive stems, and bright parsley leaves bring this humble dish to life.

Oh, and if your chives are blooming, don’t toss those blossoms. The petals make the prettiest garnish and add a subtle onion flavor that takes this humble potato salad straight into showstopper territory at summer cookouts. I like to dry them too and sprinkle them over all kinds of dishes. They’re especially lovely on my goat cheese appetizer with fig jam and hot honey—just a little touch of garden beauty on the plate.

🌿 Ingredients You’ll Need

Russet potatoes – Yes, the humble baking potato! They’re fluffy, tender, and soak up dressing like champs. If you prefer, substitute with red or Yukon gold potatoes.

Eggs – For that classic old-fashioned potato salad richness.

Mayonnaise – Adds creaminess. If you have farm-fresh eggs, try my homemade, easy mayonnaise recipe. You can lighten it up with a spoonful of Greek yogurt or sour cream if you’d like.

Mustard relish – This is where the flavor really comes alive. It’s sweet, tangy, and has just the right amount of zip. I like to use my zesty mustard relish, but store-bought works just fine too. No mustard relish on hand? Just mix a little sweet pickle relish with a spoonful of Dijon mustard for a quick and tasty substitute.

Onion – Use your favorite onion. I prefer a sweet onion, but use yellow or red onions if you prefer. Fresh green onions are another good alternative.

Apple cider vinegar – Just enough to brighten and balance the creamy base. If you don’t have any apple cider vinegar on hand, then use white wine vinegar or even plain white vinegar.

Chopped dill, parsley, and chives – Herbs straight from the garden are best for fresh flavor. If you only have one or two, that’s okay—this salad is forgiving.

Salt and black pepper – The basic ingredients of any good dish.

Optional garnish: Chive flower petals – They’re edible, pretty, and give you full garden bragging rights.

👩‍🍳 How to Make this Potato Salad with Herbs and Mustard Relish

Boil the Potatoes

Pin it

Peel and cut your russets into bite-sized chunks, about 3/4 inch pieces. Place the cut potatoes in a large pot of water. Make sure there is enough water to cover the cut potatoes, add a bit of salt, and bring to a gentle boil. Always start with cold water, especially when cooking Russet potatoes, since they break down more easily than wax potatoes. Cook until just fork-tender—about 8 to 10 minutes. Drain and let cool completely, which I like to do by spreading them out on a baking sheet so they cool quicker. Don’t rush this step or you’ll end up with mashed potato salad (still tasty, but not the goal here).

Hard Boil the Eggs

Place your eggs into boiling water, bring the water back to a boil, and cook for 10 minutes. I use eggs from my chickens, so if you use store-bought extra-large eggs, you may need to cook them a little longer. TIP: Once the time is done, place the hot eggs into an ice bath to make them easier to peel.

Make the Dressing

In a large bowl, mix the mayonnaise, mustard relish, apple cider vinegar, salt, and pepper. Stir in your chopped fresh chives, dill, and parsley. You’ll start to see the flavors come together already.

Fold in the Potatoes and Eggs

Pin it

Let the tender, warm potatoes completely cool. Once cooled, gently fold them into the creamy dressing along with three of the chopped hard-boiled eggs. I like to save the 4^th egg to add as part of the garnish on the finished salad. Take it slow—Russets are delicate when cooked. A rubber spatula works best here to avoid breaking them up too much.

Chill & Serve

Cover the bowl and let it chill in the fridge for at least 2 hours for the best flavor. This step is non-negotiable—the flavors need time to mingle and marry. After the salad has chilled for a couple of hours, taste and adjust seasoning as needed—don’t be shy with the salt or vinegar if it needs a little wake-up. Right before serving, garnish with the last chopped egg and sprinkle with more dill, chives, or chive flower petals for a rustic, garden-fresh finish.

How to fix bland potato salad?

• Potatoes Matter: Depending on the type of potato you used and the size in which they were cut.  The dressing will absorb a little differently. So, after the potato salad has chilled for at least 2 hours, and you find that your potato salad tastes a little bland, the fix is easy. Here are a few ideas:
• Seasoning:  Lack of salt and pepper is usually the problem since potatoes absorb a lot of salt.
• Acid and Tang: To help brighten the flavor of the potato salad, add a spoonful of additional apple cider vinegar or a little pickle or lemon juice.
• Additional Herbs:  If the potato salad is a little lackluster, add just a bit more herbs.
• Temperature:  Even though you never want your potato salad sunbathing on the picnic table, letting it sit out for 10–15 minutes before serving does it a world of good. The flavors wake up a bit more when it’s not fridge-cold. That said—don’t get too cozy. Mayo potato salad should never hang out at room temperature for more than 4 hours. No one wants to be that potato salad people remember for all the wrong reasons.

🪴 Tips from My Garden Table

• Potatoes: Russets give that soft, classic texture, but you can use red or Yukon gold if you prefer firmer bites, and the bonus is that you don’t have to peel them.
• Herbs: Use whatever you’re growing! Tarragon, basil, cilantro, or even a little mint could be fun if you’re feeling adventurous.
• Relish: If you haven’t tried mustard relish before, you’re in for a treat. It adds sweetness, tang, and spice in one easy spoonful.
