This creamy, tangy red potato salad is the perfect summer side dish, made with green onions, Dijon mustard, hard-boiled eggs, and fresh dill blended into a sour cream & mayo dressing. It’s easy to make and an absolute must for potlucks, picnics, and cookouts.

Cheryl’s Notes
- Red potatoes are the absolute best for this salad (obviously), but if you can’t find them, don’t panic. Other waxy potato varieties will work, too! Just make sure to use something like fingerling potatoes or new potatoes. Starchy potatoes like russets won’t hold up well and don’t give you that delicious creamy texture.
How to Make This Recipe
See recipe card below for full list of measurements, ingredients, and instructions.
Prep the Potatoes
Boil red potatoes in salted water until they’re fork tender, then carefully slice each potato into 4 quarters. Toss them in a large bowl with a little white vinegar, then set them aside while you make the dressing.
Make the Dressing
Pulse hard-boiled egg yolks and capers (optional) in a food processor until they’re chopped well, then add the rest of the dressing ingredients. Process everything together until the dressing is nice and creamy. Make sure to scrape down the sides of the bowl every so often so you don’t miss anything!
Mix It All tOGETHER
Stir together the dressing and the quartered red potatoes until the potatoes are completely coated. Cover the bowl and chill the potato salad at least 2 hours – but overnight is even better! After it’s chilled, serve the potato salad cold or at room temperature.
A Tip from Cheryl: The longer the salad chills, the more pronounced the flavors will be. If you have time to make the salad in advance and chill it overnight, do it!
What I Love About This Recipe
Rich, creamy potato salad. Is there anything more perfect for a summer side dish? Our unique version of the classic gets its flavor from creamy red potatoes, tangy Dijon mustard, white vinegar, salty capers, sour cream, and fresh herbs.
This recipe also uses easy to find, inexpensive ingredients and pantry staples, making it budget-friendly, too. It’s perfect for making memories over heaping servings at picnics, barbecues, or just around the dinner table.
Recipe Variations
- Make it Gluten Free: Double check your Dijon mustard and make sure it doesn’t include any sneaky gluten ingredients.
Making changes to a recipe can result in recipe failure. Any substitutions or variations listed are simple changes that I believe will work in this recipe, but results are not guaranteed.

What to Serve with Potato Salad
Red potato salad is a staple at all my summer cookouts. It just goes so well with any quintessential “summer” entrรฉe!
Grilling out this weekend? My black bean burgers, grilled beef ribs, pork belly burnt ends, or copycat Texas Roadhouse herb crusted chicken would all be stellar potato salad partners. Add some Mexican street corn salad, grilled broccoli, and grilled green tomatoes. Dinner is set!
For potlucks and picnics, try it with BBQ chicken salad served on buttery croissants and a helping of fresh fruit.
Frequently Asked Questions
Yes! Making it the night before gives the flavors in the dressing time to develop and deepen. I don’t recommend making red potato salad more than 24 hours in advance, though.
You can – sort of. Any waxy potato will work here, so feel free to swap in fingerling potatoes or new potatoes. Starchy potatoes like russets won’t hold up well and won’t be creamy enough.
