Ingredients
- 2 pounds baby 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 Dijon mustard
- 2 tablespoons apple cider vinegar
- 1/4 cup fresh dill, chopped

Step-by-Step Instructions
Step 1: Cook the potatoes in a large pot of salted boiling water until fork-tender, about 15-20 minutes. Drain and let cool slightly.
Step 2: While potatoes are cooking, blanch the green beans in 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, Dijon mustard, apple cider vinegar, 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 to combine, ensuring everything is evenly coated.
Step 5: Season with salt and pepper to taste. Cover and refrigerate for at least 2 hours, or overnight for best flavor development.
Expert Tips
