Ingredients
- 2 pounds small red potatoes, quartered
- 1 pound fresh green beans, trimmed and cut into 1-inch pieces
- 1/2 cup mayonnaise
- 1/4 cup sour cream
- 2 tablespoons apple cider vinegar
- 1 tablespoon Dijon mustard
- 1/4 cup finely chopped red onion
- 2 tablespoons fresh dill, chopped
- 2 tablespoons fresh parsley, chopped
- 1 teaspoon garlic powder
- Salt and freshly ground black pepper to taste
- 2 hard-boiled eggs, chopped (optional)
Step-by-Step Instructions
Step 1: Cook the potatoes in a large pot of salted boiling water until fork-tender, about 10-12 minutes. Drain and let cool slightly.
Step 2: While potatoes are cooking, blanch the green beans in another pot of boiling water for 3-4 minutes until bright green and crisp-tender. Immediately transfer to an ice bath to stop the cooking process, then drain well.
Step 3: In a large bowl, whisk together mayonnaise, sour cream, apple cider vinegar, Dijon mustard, garlic powder, salt, and pepper until smooth and well combined.
Step 4: Add the slightly cooled potatoes, blanched green beans, red onion, fresh dill, and parsley to the dressing. Gently toss to coat all ingredients evenly.
Step 5: If using, fold in the chopped hard-boiled eggs.
Step 6: Cover and refrigerate for at least 2 hours, or overnight, to allow flavors to meld together.
Step 7: Before serving, give the salad a gentle stir and adjust seasoning if needed. Garnish with additional fresh herbs.
Expert Tips
For the best texture, don’t overcook the potatoes or green beans. They should be tender but still hold their shape. The ice bath step for the green beans is crucial for maintaining their vibrant color and crisp texture. This salad tastes even better the next day, making it perfect for meal prep or make-ahead occasions. For a lighter version, you can substitute Greek yogurt for half of the mayonnaise.
