Ingredients:
- 3 pounds small red potatoes
- 1 tablespoon salt (plus 1 teaspoon for later)
- 1 tablespoon white vinegar
- ½ cup green onions (roughly chopped)
- 2 tablespoons capers (optional)
- 4 hard-boiled eggs (yolks only)
- 1 cup sour cream
- ½ cup mayonnaise
- 2 teaspoons Dijon mustard
- ¼ cup fresh dill (chopped)
- ½ teaspoon freshly ground black pepper
Instructions:
- In a large pot, bring salted water to a boil. Add the red potatoes and cook for 20-30 minutes, or until tender enough for a fork to slide through and the skins begin to peel away. Drain the potatoes, then cut them into halves, followed by quarters. Toss the cut potatoes with white vinegar while they’re still warm.
- In a food processor, combine the green onions and capers (if using) and process until finely chopped.
- Add the hard-boiled egg yolks, sour cream, mayonnaise, Dijon mustard, fresh dill, black pepper, and 1 teaspoon of salt to the food processor. Process until the mixture is creamy and smooth.
- Pour the creamy egg yolk mixture over the potatoes. Gently stir, using the back of a spoon or a potato masher to mash some of the potatoes while leaving larger chunks for texture.
- Cover the potato salad and refrigerate for at least 2 hours, or overnight, to allow the flavors to meld together.
Why You’ll Love This Recipe
This red potato salad is the perfect combination of creamy and tangy flavors, with the right amount of texture. The use of sour cream and mayonnaise creates a rich and indulgent dressing, while fresh ingredients like dill and green onions elevate the flavors. It’s a great dish for any occasion, whether you’re preparing a picnic meal, a barbecue, or a family gathering.

Tips

- Potato size: Small red potatoes are ideal for this recipe because they hold their shape well after boiling.

- Add-ins: Include chopped pickles, bacon crumbles, or a bit of shredded cheese for extra flavor.
- Capers: If you’re not a fan of capers, feel free to omit them or swap them for finely chopped olives for a different flavor profile.
