A fresh and tangy potato salad featuring tender Yukon Gold or red potatoes, crisp cucumber, fresh dill, and a creamy whole grain mustard dressing. Perfect for summer barbecues and light meals.

Ingredients

Scale
  • 2 pounds Yukon Gold or red potatoes, washed and cut into bite-sized pieces
  • 1 large English cucumber, thinly sliced
  • ¼ cup fresh dill, finely chopped
  • 2 tablespoons whole grain mustard
  • ½ cup mayonnaise
  • 1 tablespoon apple cider vinegar
  • 2 tablespoons extra virgin olive oil
  • 2 stalks green onions, thinly sliced
  • 1 small clove garlic, minced (optional)
  • Salt and black pepper to taste
  • Optional: handful of chopped fresh parsley or a squeeze of lemon juice

Instructions

  1. Place the cut potatoes in a large pot and cover with cold water by at least an inch. Add a pinch of salt. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 12-15 minutes until the potatoes are fork-tender but not falling apart. Drain well and let cool slightly.
  2. While potatoes cook, thinly slice the English cucumber. If the skin is thick or waxed, peel it first. Place slices in a colander, sprinkle lightly with salt, and let them sit for 10 minutes. Gently pat dry with paper towels.
  3. In a medium bowl, whisk together the whole grain mustard, mayonnaise, apple cider vinegar, olive oil, and minced garlic (if using). Add salt and pepper to taste.
  4. In a large bowl, add the warm potatoes, sliced cucumbers, chopped dill, and green onions. Pour the dressing over and gently toss everything together until well coated.
  5. Taste and add extra salt, pepper, or a splash more vinegar if needed. Optionally, add a small squeeze of fresh lemon juice.
  6. Cover and refrigerate for at least 30 minutes before serving. Serve chilled or at room temperature.

Notes

Use waxy potatoes like Yukon Gold or red potatoes to hold shape. Salt cucumbers and pat dry to prevent sogginess. Toss gently to avoid breaking potatoes. The salad tastes better after chilling for a few hours or overnight. For dairy-free, substitute mayonnaise with plant-based alternative. Whole grain mustard adds texture and tang; Dijon can be used but lacks crunch.
