During the warmer months, I find myself relying on simple make-ahead salads more than almost anything else.
If I can spend a little time preparing a salad on Sunday, lunches and light dinners become much easier throughout the week.
This Chicken Potato Salad with Mustard Vinaigrette is one of my favorites. Tender potatoes, chunks of chicken, colorful bell peppers, scallions, and fresh herbs are tossed in a tangy mustard dressing instead of the traditional mayonnaise-based dressing.
The result is a light, flavorful salad that’s hearty enough to serve as a complete meal and travels well for picnics, potlucks, and packed lunches.
If you’re looking for a healthier potato salad or a new way to use leftover chicken, this recipe is worth trying.

Ingredients & Substitutions
Red Potatoes – Small red potatoes hold their shape beautifully in salads. Yukon Gold potatoes are another excellent option.
Chicken – Boneless skinless chicken breasts keep things lean, but leftover grilled chicken, rotisserie chicken, or even turkey work just as well.
Bell Peppers – Red and yellow peppers add sweetness and color. Orange peppers or chopped cucumber are good substitutes.
Scallions – Provide mild onion flavor. Finely diced red onion can be substituted.
Fresh herbs – Parsley and thyme add freshness. Dill, basil, or chives also work well.
Mustard Vinaigrette – The combination of red wine vinegar, olive oil, and coarse-grain Dijon mustard creates a bright, tangy dressing that keeps the salad light while adding plenty of flavor.
How to Make Potato Salad with Chicken
Step 1: Cook the Potatoes
Place the potatoes in a saucepan and cover with water by about 1 inch. Add salt and bring to a boil.
Reduce heat and simmer until fork-tender, about 10 to 15 minutes. Drain, rinse briefly with cool water, and transfer to a large bowl.
Step 2: Cook the Chicken
While the potatoes cook, poach the chicken in gently simmering water until cooked through, about 6 minutes.
Transfer to the bowl with the potatoes.
Step 3: Add the Vegetables
Add the bell peppers, scallions, parsley, thyme, and lemon zest (if using).
Step 4: Make the Dressing
Whisk together the vinegar, olive oil, mustard, salt, and pepper.
Step 5: Toss and Chill
Pour the dressing over the salad and toss gently to combine.
Cover and refrigerate for at least 2 hours before serving.
Recipe Notes
One of the things I like most about this salad is that it gets better as it sits.
The potatoes absorb some of the mustard vinaigrette while the flavors have time to blend.
This recipe is also a great way to use leftover grilled chicken or rotisserie chicken. Simply skip the poaching step and stir in cooked chicken when assembling the salad.
For even more flavor, add a handful of chopped fresh dill or a few capers.
Serving Suggestions
Serve this chicken potato salad:
- As a light lunch
- For meal prep lunches
- At picnics and potlucks
- Alongside grilled vegetables
- With fresh fruit
- As part of a summer buffet
Because it doesn’t contain mayonnaise, it’s also a little easier to transport than traditional creamy potato salads.
