Ingredients

Scale

Potatoes

  • 1 pound baby Yukon gold potatoes (or red potatoes)

Herbs

  • 2 tablespoons chives (finely chopped)
  • 2 tablespoons tarragon (finely chopped or use dill)

Dressing

  • 3 tablespoons extra virgin olive oil
  • 1 tablespoon lemon juice
  • 1 ½ tablespoons Dijon mustard
  • 1 ½ tablespoons grainy mustard
  • 3 tablespoons mayonnaise
  • 5 peperoncini (finely chopped)
  • 1 teaspoon kosher salt (or more to taste)

Instructions

  1. Cook the potatoes: Add the potatoes to a pot, cover them with water and add kosher salt. Bring the water to a boil and cook the potatoes until they are fork tender, which should take about 10-12 minutes.
  2. Drain and slice: Drain the cooked potatoes and let them cool for a few minutes. Once cooled, slice the potatoes into ¼ inch thick circles.
  3. Make the Dijon vinaigrette: In a small bowl, combine the extra virgin olive oil, lemon juice, Dijon mustard, grainy mustard, mayonnaise, finely chopped peperoncini, and salt. Mix thoroughly to create a smooth and tangy dressing. Adjust seasoning to taste if necessary.
  4. Assemble the potato salad: In a mixing bowl, combine the sliced potatoes with the vinaigrette and chopped herbs (chives and tarragon or dill). Toss gently to ensure the potatoes are evenly coated with the tangy dressing and herbs. Serve immediately.

Notes

  • Use baby Yukon gold potatoes for a creamy texture, or red potatoes for a slightly firmer bite.
  • Fresh tarragon gives a subtle anise flavor, but dill can be used as a tasty alternative.
  • Peperoncini add a mild heat and tang—adjust quantity according to preference.
  • This salad is best served slightly warm or at room temperature for maximum flavor.
  • Mayonnaise can be substituted with Greek yogurt for a lighter version.
