Ingredients

• 2 pounds Yukon Gold potatoes, cut into 1-inch cubes
• 1 pound fresh green beans, trimmed and cut into 2-inch pieces
• 1/2 cup mayonnaise
• 1/4 cup sour cream
• 2 tablespoons Dijon mustard
• 1 tablespoon apple cider vinegar
• 1/4 cup finely chopped red onion
• 2 tablespoons chopped fresh dill
• 2 tablespoons chopped fresh parsley
• 1 teaspoon garlic powder
• Salt and 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 well 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 ice water to stop cooking, then drain thoroughly.

Step 3: In a large bowl, whisk together mayonnaise, sour cream, Dijon mustard, apple cider vinegar, garlic powder, salt, and pepper until smooth and creamy.

Step 4: Add the cooled potatoes, green beans, red onion, dill, and parsley to the dressing. Gently toss to coat everything evenly.

Step 5: If using, fold in the chopped hard-boiled eggs. Cover and refrigerate for at least 1 hour before serving to allow flavors to develop.

Expert Tips

For the best texture, don’t overcook the potatoes – they should be tender but still hold their shape. The green beans should retain some crunch to contrast with the creamy potatoes. This salad pairs wonderfully with other summer favorites like Mexican street corn salad for a complete meal spread.

Make this salad up to 24 hours in advance – the flavors actually improve as they meld together in the refrigerator. If you’re serving it at a picnic, pack it in a cooler to keep it chilled. For a lighter version, you can substitute Greek yogurt for half of the mayonnaise.

Frequently Asked Questions

Can I use frozen green beans? Yes, frozen green beans work well. Thaw them completely and pat dry before using to prevent excess moisture in the salad.

How long does this salad keep in the refrigerator? It will stay fresh for 3-4 days when stored in an airtight container. The texture may soften slightly over time.

What other vegetables can I add? Try adding chopped celery, bell peppers, or cherry tomatoes for extra color and crunch. This salad also complements other vegetable sides like sesame green beans for variety.

Can I make this dairy-free? Absolutely! Use vegan mayonnaise and dairy-free sour cream alternatives for a plant-based version that’s just as delicious.
