Ingredients

• 2 pounds small red 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 fresh dill, chopped
• 2 tablespoons fresh parsley, chopped
• 1/2 cup red onion, finely diced
• 3 hard-boiled eggs, chopped
• Salt and pepper to taste

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, diced red onion, and chopped hard-boiled eggs to the dressing. Gently toss to combine, being careful not to break up the potatoes too much.

Step 5: Season with salt and pepper to taste. Cover and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to develop.

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—it preserves their vibrant color and crisp texture.

This salad pairs wonderfully with other creamy dishes like our Creamy Tuscan Salmon or can be served alongside simpler grilled options for a complete meal.

If you’re making this for a large gathering, you can easily double the recipe. It travels well and stays fresh for up to 3 days in the refrigerator, making it perfect for meal prep or bringing to potlucks.

FAQ

Can I use frozen green beans?
Yes, frozen green beans work well in this recipe. Just thaw them completely and pat dry before using—no need to blanch.

How far in advance can I make this salad?
This salad actually improves with time! You can make it up to 24 hours in advance. The flavors meld together beautifully when given time to rest in the refrigerator.

What can I substitute for mayonnaise?
Greek yogurt makes an excellent healthier alternative to mayonnaise while still maintaining the creamy texture. You could also try a combination of avocado and lemon juice for a dairy-free option.
