Parmesan Dill Potato Salad tastes creamy, tangy, herby, and a little cheesy in the best way possible. It works perfectly for anyone who wants a fresh twist on classic potato salad and needs a side dish on the table in about 35 minutes. I tested this version at a family cookout, and my uncle who “doesn’t like potato salad” went back for thirds.
Why Choose This Parmesan Dill Potato Salad
This potato salad packs bright dill, salty Parmesan, and a lemony kick that cuts through the richness. It feels lighter than mayo-heavy versions but still brings that comforting, picnic-style vibe.
You can prep it ahead, chill it, and pull it out when guests arrive. It travels well, holds up on a buffet, and tastes even better after the flavors mingle in the fridge.

Ingredients You’ll Need
Potatoes
- 2 pounds baby Yukon Gold potatoes, halved (or quartered if large)
- Use red potatoes if you prefer a firmer texture.
- Avoid russets since they turn too fluffy and break apart.
Dressing
- 1/2 cup mayonnaise
- Use full-fat for the best flavor; avocado oil mayo works well too.
- 1/3 cup sour cream or plain Greek yogurt
- Greek yogurt adds extra tang and protein.
- 1/3 cup finely grated Parmesan cheese
- Use real Parmigiano Reggiano if possible; pre-grated shelf-stable Parmesan works in a pinch.
- 2 tablespoons fresh lemon juice
- 1 teaspoon Dijon mustard
- 1 small garlic clove, very finely minced or grated
- 1/2 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon black pepper
Herbs & Mix-ins
- 1/4 cup fresh dill, finely chopped
- Use dried dill only if needed: start with 1 tablespoon and adjust.
- 2 green onions, thinly sliced (white and green parts)
- 1/4 cup finely chopped celery (optional, for crunch)
- 1 tablespoon finely chopped fresh parsley (optional, for color)
Pantry shortcuts & substitutions
- Use bottled lemon juice if fresh lemons hide from you, but taste and adjust since it can taste sharper.
- Use pre-minced garlic from a jar, but use a light hand since it tastes stronger.
- Swap half the mayo for more Greek yogurt if you want a lighter dressing.
- Add a spoonful of pickle relish if your crew loves a tangier, old-school potato salad vibe.
Equipment
- Medium pot with lid
- Colander
- Large mixing bowl
- Small bowl for dressing
- Sharp knife and cutting board
- Rubber spatula or large spoon
- Microplane or fine grater for Parmesan and garlic
Tips & Tricks
- Cut potatoes into equal sizes so they cook at the same rate.
- Salt the cooking water generously so the potatoes taste seasoned from the inside out.
- Boil potatoes just until fork-tender; stop cooking as soon as a fork slides in with slight resistance.
- Drain potatoes well and let them steam off for a few minutes so the dressing clings instead of sliding off.
- Toss potatoes with part of the dressing while they still feel warm to help them soak up flavor.
- Chill the salad at least 30 to 60 minutes before serving for the best Parmesan dill flavor.
- Taste again after chilling and adjust salt, pepper, or lemon juice since flavors mellow in the fridge.
- Add extra fresh dill and a sprinkle of Parmesan on top right before serving for a fresh, pretty finish.
How to Make Parmesan Dill Potato Salad
Step 1: Prep and cook the potatoes
Rinse the baby Yukon Gold potatoes and scrub off any dirt. Cut them into halves or quarters so they match in size. Place them in a pot, cover with cold water by about an inch, and add 1 to 2 teaspoons of kosher salt.
Bring the pot to a gentle boil over medium-high heat. Lower the heat to maintain a steady simmer. Cook the potatoes for about 10 to 15 minutes, until a fork slides in easily but the pieces still hold their shape.
Drain the potatoes in a colander. Let them sit for 5 minutes so steam escapes and excess moisture evaporates. Spread them out slightly if they look very wet.
Step 2: Mix the Parmesan dill dressing
In a small bowl, add mayonnaise, sour cream or Greek yogurt, grated Parmesan, lemon juice, Dijon mustard, garlic, salt, and pepper. Whisk until the mixture looks smooth and creamy. Taste the dressing and adjust salt, pepper, or lemon juice to your liking.
Stir in the chopped dill and green onions. Add celery and parsley if you use them. The dressing should look thick but still pourable; thin it with a teaspoon of water or lemon juice if it seems too thick.
Step 3: Combine potatoes and dressing
Transfer the warm potatoes to a large mixing bowl. Spoon about two-thirds of the dressing over the potatoes. Gently fold with a spatula so you coat the potatoes without smashing them.
Let the mixture sit for 5 to 10 minutes so the warm potatoes absorb some of the dressing. Add more dressing as needed until the salad reaches your preferred level of creaminess. Save a spoonful or two of dressing for a final toss after chilling if you like a glossy finish.
Step 4: Chill and finish
Cover the bowl and chill the Parmesan Dill Potato Salad in the fridge for at least 30 minutes, or up to 24 hours. Right before serving, give the salad a gentle stir. Add the remaining dressing if the potatoes soaked up a lot.
Taste again and add a pinch of salt, a squeeze of lemon, or extra dill if the flavors need a boost. Sprinkle more Parmesan and a little dill or parsley on top for a fresh, herby look. Serve cold or at cool room temperature.
What to Serve with it?
This Parmesan Dill Potato Salad pairs beautifully with grilled chicken, turkey burgers, or veggie burgers. It also works with baked salmon, roasted chicken thighs, or simple pan-seared tofu. Add a crisp green salad, grilled corn, or sliced watermelon to round out a summer-style plate. For a potluck, place it next to coleslaw, pasta salad, and a big platter of cut veggies with hummus.
Storage Options
- Store leftover Parmesan Dill Potato Salad in an airtight container in the fridge for up to 3 to 4 days.
- Stir before serving leftovers, and add a spoonful of mayo or yogurt plus a splash of lemon juice if it looks a little dry.
- Avoid freezing this salad, since potatoes and dairy dressing turn grainy and watery after thawing.
- Serve leftovers cold straight from the fridge, or let them sit at room temperature for 10 to 15 minutes to take off the chill.
