When the warm weather hits, all I want is a refreshing and hearty potato salad. This potato and green bean salad is a combo of two of my favorite things — tender baby potatoes and crisp green beans tossed in a zesty Dijon vinaigrette. It’s bright, satisfying, and finished with a sprinkle of creamy feta for that perfect salty bite. Whether you’re serving it at a backyard barbecue, packing it for a picnic, or enjoying it as a light lunch, this easy side dish is sure to become a seasonal staple.

Potato and Green Bean Salad Recipe
I’ve never been a fan of traditional mayo-heavy potato salads—if you’ve tried my classic potato salad without mayo, you already know that. This recipe takes the same fresh approach with perfectly tender potatoes, crisp-tender green beans, and a punchy vinaigrette made with Dijon mustard, red wine vinegar, olive oil, and a touch of honey for balance. If you’re looking for more light but flavor-packed summer sides, you’ll also love my grilled zucchini salad and lemon orzo salad with feta.
Fresh chives bring a pop of color and herby flavor, while crumbled feta adds that creamy, salty finish I love. It’s the kind of dish that feels just right for spring and summer—great for backyard BBQs, potlucks, or even as a make-ahead lunch.

Sarah's Top Tips
- I always cut my potatoes into bite-sized pieces before boiling them—this helps them keep their shape and makes the salad easier to eat. Just be sure to cut them as evenly as possible so they cook at the same rate.
- For the best texture in potato salad, go with small, thin-skinned varieties that hold their shape well after cooking. I used a mix of red and yellow potatoes in this recipe, but white or fingerling potatoes also work beautifully.
- Tossing the potatoes and green beans with the vinaigrette while they’re still warm helps them soak up all that tangy flavor. I always pour on just enough to coat, then save the rest for another day—it’s too good to waste!
- Keep a close eye on the green beans—5 minutes is usually perfect. You want them bright green with a little snap.

Serving Suggestions
I’ll be making this for all my summer get-togethers this year to go alongside burgers, hot dogs, and any other grilled favorites. It’s the kind of side that goes with everything and never feels too heavy, especially on a hot day. It pairs beautifully with grilled chicken, sausages, salmon, or even a simple sandwich if you’re keeping things casual. I’ve even packed it up for picnics and beach days—it travels well and tastes great cold or at room temperature. Honestly, I’ll probably snack on it all day as well.
Storage & Reheating
This salad actually gets better as it sits. If you have the time, let it chill in the fridge for 30 minutes to an hour before serving. The flavors meld, and it tastes even more delicious cold or at room temperature. Keep stored in the fridge for up to 4 days.
