Ingredients

Scale
  • 3 pounds (about 1.4 kg) medium Yukon Gold or red potatoes, cut into 1-inch chunks
  • 4 large hard-boiled eggs, peeled and chopped
  • 2 stalks celery, finely diced
  • 1/4 cup (60 ml) yellow mustard
  • 1/2 cup (120 ml) mayonnaise, full-fat
  • 2 tablespoons (30 ml) apple cider vinegar
  • 1 tablespoon (12 g) granulated sugar (optional)
  • 2 tablespoons (30 ml) pickle relish, sweet or dill
  • 1 small onion, finely chopped (red or white)
  • Salt and black pepper, to taste
  • 2 tablespoons fresh parsley or chives, chopped (optional)

Instructions

  1. Wash and cut potatoes into 1-inch chunks. Place in a large pot and cover with cold water by 1 inch. Add a pinch of salt. Bring to a boil over medium-high heat, then reduce to medium and simmer for 12-15 minutes until tender but not mushy.
  2. Drain potatoes in a colander and set aside to cool completely.
  3. Place eggs in a saucepan and cover with cold water by 1 inch. Bring to a boil, then cover and remove from heat. Let sit for 10-12 minutes. Cool under cold running water, peel, and chop finely.
  4. Finely dice celery and onion. Set aside.
  5. In a medium bowl, whisk together mustard, mayonnaise, apple cider vinegar, sugar (if using), and pickle relish. Season with salt and pepper to taste.
  6. In a large mixing bowl, gently fold together cooled potatoes, chopped eggs, celery, and onion. Pour dressing over and stir carefully until evenly coated, avoiding overmixing.
  7. Cover and refrigerate for at least 2 hours or overnight. Just before serving, garnish with chopped parsley or chives.

Notes

Cool potatoes completely before mixing with dressing to avoid watery salad. Adjust mustard and mayo ratios to taste. Use an egg slicer for even chopped eggs. For a lighter version, substitute some or all mayonnaise with Greek yogurt. Add a splash of vinegar or salt after chilling if flavor is flat.
