Ingredients

• 2 pounds baby potatoes, quartered
• 1 pound fresh green beans, trimmed and cut into 1-inch pieces
• 1 cup mayonnaise
• 1/4 cup sour cream
• 2 tablespoons Dijon mustard
• 2 tablespoons apple cider vinegar
• 1/4 cup finely chopped fresh dill
• 2 tablespoons chopped fresh parsley
• 1/4 cup finely chopped red onion
• 2 celery stalks, finely diced
• Salt and freshly ground black pepper to taste
• Optional: 2 hard-boiled eggs, chopped

Step-by-Step Instructions

Step 1: Cook the potatoes in a large pot of salted boiling water until tender but still firm, 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 thoroughly.

Step 3: In a large mixing bowl, whisk together mayonnaise, sour cream, Dijon mustard, apple cider vinegar, chopped dill, and parsley until smooth and creamy.

Step 4: Add the slightly cooled potatoes, blanched green beans, red onion, and celery to the dressing. Gently toss until everything is evenly coated.

Step 5: Season with salt and pepper to taste. If using, fold in the chopped hard-boiled eggs.

Step 6: Cover and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to meld together. Serve chilled.

Expert Tips

For the best texture, don’t overcook the potatoes or green beans. They should be tender but still have some bite to prevent the salad from becoming mushy. The ice bath step for the green beans is crucial—it preserves their vibrant color and crisp texture.

This salad tastes even better the next day, making it perfect for meal prep or entertaining. If you’re serving it at an outdoor event, keep it chilled in a cooler until ready to serve. For a lighter version, you can substitute Greek yogurt for half of the mayonnaise.

FAQ

Can I make this salad ahead of time?
Absolutely! This salad actually benefits from sitting in the refrigerator for several hours or overnight. The flavors meld together beautifully, and the texture remains perfect.

How long does it keep in the refrigerator?
Stored in an airtight container, this potato salad will keep well for 3-4 days. The vegetables may soften slightly over time, but it will still taste delicious.

Can I use frozen green beans?
While fresh green beans are recommended for the best texture and flavor, you can use frozen green beans in a pinch. Thaw them completely and pat dry before using to avoid excess moisture in the salad.
