Ingredients
For the Salad:
- 2 pounds baby potatoes, halved or quartered
- 1 pound fresh green beans, trimmed and cut into 2-inch pieces
- 1/2 cup red onion, finely diced
- 1/4 cup fresh dill, chopped
- 2 tablespoons fresh parsley, chopped
- 3 hard-boiled eggs, chopped (optional)
For the Creamy Dressing:
- 1 cup mayonnaise
- 1/4 cup sour cream
- 2 tablespoons Dijon mustard
- 1 tablespoon apple cider vinegar
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and black pepper to taste
Step-by-Step Instructions
Step 1: Cook the Potatoes and Green Beans
Place the potatoes in a large pot and cover with cold water. Bring to a boil and cook for 10-12 minutes until fork-tender. During the last 3 minutes of cooking, add the green beans to the same pot to blanch them. Drain both and rinse with cold water to stop the cooking process.
Step 2: Prepare the Dressing
In a medium bowl, whisk together mayonnaise, sour cream, Dijon mustard, apple cider vinegar, garlic powder, and onion powder until smooth and creamy. Season with salt and pepper to taste.
Step 3: Combine Everything
In a large mixing bowl, combine the cooled potatoes, green beans, red onion, dill, and parsley. If using, add the chopped hard-boiled eggs. Pour the creamy dressing over the salad and gently toss to combine, making sure everything is evenly coated.
Step 4: Chill and Serve
Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or preferably overnight, to allow the flavors to develop. Give it a gentle stir before serving cold.
Expert Tips for Perfect Potato Salad
Choose the right potatoes: Waxy potatoes like Yukon Gold or red potatoes hold their shape better than starchy varieties, making them perfect for salads.
Don’t overcook the green beans: They should be crisp-tender to maintain that satisfying crunch against the creamy potatoes.
Make it ahead: This salad actually tastes better the next day as the flavors have time to meld together. It’s perfect for outdoor gatherings and parties where you want to prepare food in advance.
Customize the herbs: Feel free to experiment with different herb combinations. Tarragon, chives, or basil would all work beautifully in this recipe.
