Ingredients for Potato Salad With Grainy Mustard

  • Yukon Gold Potatoes
  • 1/2 medium red onion, finely chopped
  • Parsley
  • Fresh Chives
  • Fresh Tarragon
  • 2 tablespoons capers, drained
  • Grainy Mustard
  • Salt And Pepper
  • 1/4 cup extra virgin olive oil
  • White Wine Vinegar

How to Make Potato Salad With Grainy Mustard

  1. Place the quartered potatoes in a large pot and cover with cold water. Add a generous pinch of salt.
  2. Bring to a boil over high heat, then reduce heat to medium and simmer for 20-25 minutes, or until the potatoes are easily pierced with a fork.
  3. Drain the potatoes and rinse them under cold water to stop the cooking process. Set aside to cool slightly.
  4. Once cool enough to handle, peel and dice the potatoes into small, even-sized cubes.
  5. In a large bowl, combine the diced potatoes, chopped red onion, fresh herbs, capers, grainy mustard, salt, and pepper.
  6. In a small bowl, whisk together the olive oil and vinegar.
  7. Pour the dressing over the potato mixture and toss gently to combine.
  8. Cover the bowl and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to meld. Serve chilled.

Chef's Tip for Extra Flavor

Elevate your dish with simple flavor boosters! A final flourish of freshly chopped herbs can add incredible brightness, while a squeeze of lemon or lime juice right before serving can awaken all the flavors. Don't underestimate a sprinkle of quality finishing salt or a drizzle of good olive oil to make your creation shine.
