Ingredients: 3 pounds baby red potatoes, halved or quartered; 1 tablespoon kosher salt, for boiling water; 3/4 cup mayonnaise; 1/4 cup sour cream; 2 tablespoons Dijon mustard; 3 tablespoons fresh lemon juice; 1/4 cup extra-virgin olive oil; 3/4 cup freshly grated Parmesan cheese; 1/3 cup finely chopped fresh dill; 3 stalks celery, finely diced; 1/2 cup finely chopped red onion; 1 teaspoon garlic powder; 1 teaspoon kosher salt; 1/2 teaspoon freshly ground black pepper; 1/4 teaspoon paprika

Parmesan Dill Potato Salad tastes creamy, bright, and herby with little salty pops of cheese in every bite, and it totally steals the show at any cookout. It works for busy home cooks who want a make-ahead side dish in about 35–40 minutes that feels a bit fancy without any stress. I first made a version of this on a sweltering July afternoon in my tiny apartment kitchen, and my friends still ask about “that dill potato thing” years later.

Why Parmesan Dill Potato Salad Is Worth It

This potato salad hits that perfect balance of tangy, savory, and fresh. The Parmesan adds nutty richness, the dill keeps everything bright, and a lemony dressing cuts through the creaminess so it never feels heavy. You get picnic comfort food with just enough flair to impress your pickiest relative.

It also works beautifully as a make-ahead dish. The flavors deepen in the fridge, so you can cook once and enjoy it for days. I love it as a “cook once, eat twice” side that turns leftover grilled chicken or tofu into a full meal.

“I brought this Parmesan Dill Potato Salad to a family barbecue, and people skipped the burgers to go back for seconds of the salad. The dill tasted super fresh, the Parmesan gave it a cheesy kick, and the texture stayed creamy without turning gloopy. My aunt asked for the recipe before she even finished her plate.”

Ingredients You Need

Potatoes

2 pounds small yellow or Yukon Gold potatoes, scrubbed
- Thin skins save peeling time and hold their shape well.
- You can use red potatoes instead; they stay firm and look pretty in the bowl.

Dressing

1/2 cup mayonnaise
- Use a full-fat mayo like Hellmann’s / Best Foods for the best texture.
- You can swap half the mayo with plain Greek yogurt for a lighter, tangier version.
1/3 cup sour cream or plain Greek yogurt
1/4 cup finely grated Parmesan cheese
- Use real Parmigiano Reggiano if possible; pre-grated shelf-stable Parmesan works in a pinch but tastes milder.
2–3 tablespoons fresh lemon juice (about 1 lemon)
1 tablespoon Dijon mustard
1–2 teaspoons honey or sugar, to balance the acidity
1/2–3/4 teaspoon fine sea salt, plus more to taste
1/2 teaspoon black pepper, freshly ground

Herbs & Aromatics

1/3–1/2 cup fresh dill, finely chopped (stems removed)
2 green onions, thinly sliced (white and green parts)
1 small celery stalk, finely diced (optional, for crunch)
1–2 cloves garlic, very finely minced or grated
- Use a microplane so the garlic melts into the dressing.

Optional Add-Ins

1/4 cup finely grated Parmesan, extra, for topping
2 hard-boiled eggs, chopped, for extra richness
1/4 cup finely chopped pickles or cornichons, for tang and crunch
1/4 cup finely chopped red onion, for sharper bite
1–2 tablespoons capers, drained, for briny flavor

Pantry Shortcuts & Substitutions

Use pre-washed baby potatoes to skip scrubbing and peeling.
Use jarred minced garlic if you need speed, but use a light hand since it tastes stronger.
Use dried dill (1–1.5 teaspoons) only if you cannot access fresh, and add it directly to the dressing so it hydrates.
Use pre-shredded Parmesan from the refrigerated section when you do not want to grate by hand.

Equipment List

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

Quick Tips & substitutions

Cut potatoes into even chunks (about 1–1.5 inches) so they cook at the same rate.
Start potatoes in cold, salted water so they cook evenly and soak up seasoning.
Boil until just fork-tender; stop before they fall apart to keep the salad from turning mushy.
Dress potatoes while still warm so they absorb flavor, but let them cool slightly so the mayo does not separate.
Taste and adjust salt and lemon juice after the salad chills; cold food needs a bit more seasoning.
Swap half the mayo with Greek yogurt for a lighter dressing that still tastes creamy.
Use vegan mayo and a vegan Parmesan-style cheese to keep the salad dairy-free and egg-free.
Skip Parmesan and add extra dill and lemon for a brighter, herb-forward version.
Use red potatoes if you want a firmer texture that holds up longer in the fridge.
Stir in chopped pickles, capers, or a spoonful of pickle brine if you love tangy potato salad.

How to Make Parmesan Dill Potato Salad

Step 1: Cook the Potatoes

Rinse the potatoes and cut them into bite-size chunks, about 1–1.5 inches. Place them in a large pot and cover with cold water by about an inch. Add a generous pinch of salt so the potatoes taste seasoned from the inside out. Bring the water to a gentle boil over medium-high heat, then lower the heat slightly and simmer until the potatoes feel just tender when you pierce them with a fork, about 10–15 minutes.

Once the potatoes reach fork-tender, drain them in a colander. Spread them out slightly so steam escapes and they cool faster. While they still feel warm but not scorching, transfer them to a large mixing bowl. This warm stage helps them soak up the dressing without turning mushy.

Step 2: Mix the Dressing

In a small bowl or jar, add mayonnaise, sour cream (or Greek yogurt), grated Parmesan, lemon juice, Dijon mustard, honey or sugar, salt, and black pepper. Whisk until the dressing looks smooth and creamy with no streaks. Taste and adjust seasoning; add more lemon for brightness, more honey for balance, or more salt if it tastes flat. The dressing should taste slightly stronger than you want the final salad, since the potatoes will mellow it out.

Step 3: Add Dill and Aromatics

Add chopped dill, green onions, celery (if using), and minced garlic to the warm potatoes in the large bowl. Toss gently to distribute the herbs and aromatics. This step helps the herbs cling to the potatoes before the dressing goes on. The bowl already smells amazing at this point, which always makes me snack on a potato or two.

Step 4: Dress the Potatoes

Pour about two-thirds of the dressing over the warm potatoes. Use a rubber spatula or large spoon to fold everything together gently, so the potatoes stay mostly intact. Add more dressing as needed until the salad looks creamy but not soupy. Hold back a few spoonfuls of dressing if you plan to serve the salad the next day, so you can freshen it up before serving.

Step 5: Chill and Finish

Cover the bowl and chill the Parmesan Dill Potato Salad in the fridge for at least 1 hour, or up to a full day. The flavors meld as it chills, and the potatoes soak up the dressing. Right before serving, give the salad a gentle stir, then taste and adjust with a pinch of salt, a squeeze of lemon, or a spoonful of the reserved dressing. Sprinkle extra Parmesan and a little fresh dill on top for a pretty finish.

Recipe Variations

Gluten-free: The recipe already uses naturally gluten-free ingredients; just check labels on Dijon and mayo to confirm.
Vegan: Use vegan mayo, a dairy-free Parmesan-style cheese, and plant-based yogurt instead of sour cream.
Lighter version: Use half mayo and half Greek yogurt, and add extra lemon juice and dill for brightness.
Low carb twist: Swap half the potatoes with steamed cauliflower florets; dry them well so they do not water down the dressing.
Extra protein: Add chopped hard-boiled eggs, grilled chicken, or chickpeas.
More crunch: Stir in diced celery, radishes, or cucumber (seeds removed).
Extra tangy: Add chopped pickles, capers, or a splash of pickle brine.
Spicy kick: Mix in a pinch of red pepper flakes or a spoonful of your favorite hot sauce.

Ways to Serve Parmesan Dill Potato Salad

Serve alongside grilled chicken, burgers, or veggie skewers at cookouts and picnics.
Pack it in lunch boxes with sliced cucumbers, cherry tomatoes, and a boiled egg.
Spoon it over a bed of crisp greens for a hearty salad bowl.
Pair it with roasted salmon or baked tofu for an easy weeknight dinner.
Serve small portions in cups or jars for a fun party side.

Storage Success

Store Parmesan Dill Potato Salad in an airtight container in the fridge for up to 3–4 days. Stir it before serving, since the dressing can settle a bit as it chills. If it looks a little dry on day two or three, loosen it with a spoonful of mayo, yogurt, or a squeeze of lemon juice. Keep it chilled until serving time, and avoid leaving it out at room temperature for more than 1–2 hours, especially on hot days.
