Parmesan Dill Potato Salad tastes creamy, bright, and herby with little salty pops of cheese in every bite. It works perfectly for busy cooks who want a crowd-pleasing side in about 35 minutes, start to finish. I first made a version of this for a backyard potluck in 2012 and people still text me for the recipe every summer.
Why You Should Try This Parmesan Dill Potato Salad
This potato salad brings together tender baby potatoes, fresh dill, sharp Parmesan, and a tangy lemon-mayo dressing. It tastes lighter than classic mayo-heavy versions but still feels rich and satisfying.
The fresh dill keeps each bite vibrant while the Parmesan adds a nutty, salty edge that pairs with almost anything off the grill. It works just as well for weeknight dinners as it does for cookouts and holidays.

Ingredients You’ll Need
Potatoes
- 2 pounds baby gold potatoes, scrubbed and halved (or quartered if large)
- 1 tablespoon kosher salt for the boiling water
I like baby gold potatoes because they stay creamy and hold their shape. You can use red potatoes instead, which also keep a nice texture and color. Avoid russets since they break down too easily and turn the salad mushy.
Dressing
- 1/2 cup mayonnaise (Duke’s or Hellmann’s both work great)
- 1/4 cup plain Greek yogurt or sour cream
- 2 tablespoons extra virgin olive oil
- 2 tablespoons freshly squeezed lemon juice
- 1 tablespoon Dijon mustard
- 1 teaspoon honey or sugar (balances the acidity)
- 1 small garlic clove, very finely minced or grated
- 1/2 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
Greek yogurt lightens the dressing and adds a little tang. Use all mayo if you prefer a richer flavor. I like Dijon for its smooth heat, but stone ground mustard also works.
Cheese and Herbs
- 3/4 cup finely grated Parmesan cheese, packed (use a wedge if possible, not the green can)
- 1/3 cup finely chopped fresh dill, loosely packed
- 2 tablespoons finely chopped fresh chives or green onion tops
Freshly grated Parmesan melts slightly into the warm potatoes and gives better flavor than pre-grated. If you only have pre-shredded, chop it a bit finer so it distributes more evenly. Fresh dill makes this salad special, so use it generously.
Crunchy Add-ins
- 2 ribs celery, very finely diced
- 1/4 small red onion, very thinly sliced or finely minced
- 1 small Persian cucumber, finely diced (optional but adds great crunch)
These crunchy bits keep the salad from feeling heavy. If raw onion tastes too strong, soak the slices in cold water for 10 minutes, then drain and pat dry. That little step softens the bite but keeps the flavor.
Optional Flavor Boosters
- 1 teaspoon lemon zest
- 1 teaspoon capers, rinsed and chopped
- Pinch of red pepper flakes
Lemon zest brightens the whole bowl without extra acidity. Capers add a briny note that plays nicely with Parmesan and dill. Use red pepper flakes if you like a subtle kick.
Equipment List
- Large pot for boiling potatoes
- Colander
- Large mixing bowl
- Small bowl or jar for whisking the dressing
- Sharp knife and cutting board
- Microplane or fine grater for Parmesan and garlic
- Rubber spatula or large spoon for gentle mixing
Tips & Tricks
- Salt the potato cooking water generously so the potatoes taste seasoned all the way through.
- Cut potatoes into even pieces so they cook at the same rate and stay tender, not mushy.
- Test doneness with a fork; pull them when the fork slides in easily but the potato still feels intact.
- Dress the potatoes while they still feel warm so they absorb more flavor from the Parmesan dill dressing.
- Let the salad chill at least 30 minutes before serving so the flavors meld and the dressing thickens slightly.
- Add only half the Parmesan and dill at first, then taste and add more until it hits your favorite balance.
- Keep the knife cuts small on celery, onion, and cucumber so they add crunch without taking over each bite.
- If the salad thickens too much in the fridge, loosen it with a splash of lemon juice or a spoonful of yogurt.
- Taste again right before serving and adjust salt, pepper, and lemon juice; cold food usually needs a bit more seasoning.
- Use a rubber spatula and fold gently so the potatoes stay in chunks instead of turning into mashed potato salad.
How to Make Parmesan Dill Potato Salad
Step 1: Boil the potatoes
Fill a large pot with water, add the tablespoon of kosher salt, and bring it to a boil. Add the halved baby potatoes and reduce the heat to a gentle simmer. Cook 10 to 15 minutes, until a fork slides into the center easily but the potato still feels firm enough to hold its shape. Drain in a colander and let the steam escape for 5 minutes so the surfaces dry slightly.
Step 2: Mix the dressing
In a small bowl or jar, whisk together the mayonnaise, Greek yogurt, olive oil, lemon juice, Dijon mustard, honey, minced garlic, salt, and pepper. Whisk until the dressing looks smooth and creamy with no streaks. Taste and adjust with a little more lemon juice, salt, or honey until it tastes bright, tangy, and balanced. Set the dressing aside while the potatoes finish steaming.
Step 3: Prep the mix-ins
While the potatoes cook, finely chop the celery, dill, and chives, and mince or thinly slice the red onion. Dice the cucumber if you use it and pat it dry with a paper towel so it does not water down the salad. Grate the Parmesan on the fine side of a box grater or with a microplane and fluff it with your fingers so it does not clump. Keep everything ready in small piles so you can assemble quickly.
Step 4: Dress the warm potatoes
Transfer the warm potatoes to a large mixing bowl. Spoon about two thirds of the dressing over the potatoes and toss gently with a spatula until each piece looks lightly coated. Sprinkle in half of the Parmesan, half of the dill, and half of the chives, then toss again. Let the potatoes sit 5 to 10 minutes so they soak up the dressing.
Step 5: Add crunch and adjust
Add the celery, red onion, cucumber, lemon zest, and any capers or red pepper flakes to the bowl. Fold everything together gently so the potatoes stay in chunks. Add most of the remaining Parmesan and herbs, then taste. Add more dressing, salt, pepper, or lemon juice until the Parmesan Dill Potato Salad tastes creamy, tangy, and herby.
Step 6: Chill and serve
Cover the bowl and chill the salad at least 30 minutes and up to 24 hours. Right before serving, give it a gentle stir and check the texture. If it looks thick, loosen it with a spoonful of yogurt or a small splash of olive oil and lemon juice. Top with the last bit of Parmesan and dill for a fresh, pretty finish.
What to Serve with Parmesan Dill Potato Salad
Parmesan Dill Potato Salad pairs beautifully with grilled chicken, burgers, sausages, or simple baked salmon-style dishes. It also fits nicely next to veggie skewers, black bean burgers, or a big green salad for a lighter spread. I like to serve it with sliced watermelon, corn on the cob, and maybe some garlic bread for a full summer plate. It works just as well at a picnic as it does on a weeknight table with roasted vegetables.
Storage Options
- Store leftover Parmesan Dill Potato Salad in an airtight container in the fridge for up to 3 days.
- Stir before serving leftovers and taste again; add a squeeze of lemon or a spoonful of yogurt if it tastes flat.
- Avoid freezing this salad because the potatoes and creamy dressing change texture and turn grainy.
- Serve leftovers cold or let them sit at room temperature for 15 to 20 minutes; skip the microwave so the dressing stays smooth.
