My Creamy Mustard Dill Potato Salad is easy to make and the ultimate summer side dish.

How to Make Mustard Dill Potato Salad

Cut the baby potatoes in half and add them to a saucepan, cover with cold water by an inch. Bring to a boil and cook until fork tender, about 15 minutes. Drain the potatoes.

While the potatoes are cooking prepare the dressing. In a large bowl whisk together the mayonaise, mustard, vinegar, salt, and pepper until combined. Stir in the chopped dill and capers. Add the cooked potatoes to the dressing and toss to combine. Refrigerate for at least 2 hours or up to overnight. Serve chilled or at room temperature. This recipe serves 4-6 but can easily be doubled or tripled if serving a large crowd.
