Ingredients
- 2 pounds Yukon Gold potatoes, cubed
- 1 pound fresh green beans, trimmed and cut into 1-inch pieces
- 1/2 cup mayonnaise
- 1/4 cup sour cream
- 2 tablespoons apple cider vinegar
- 1 tablespoon Dijon mustard
- 1/4 cup fresh dill, chopped
- 2 tablespoons fresh parsley, chopped
- 1/4 cup red onion, finely diced
- 1 teaspoon garlic powder
- Salt and pepper to taste
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 cooking, then drain thoroughly.
Step 3: In a large bowl, whisk together mayonnaise, sour cream, apple cider vinegar, Dijon mustard, garlic powder, salt, and pepper.
Step 4: Add the cooled potatoes, green beans, red onion, dill, and parsley to the dressing. Gently toss to combine, being careful not to mash the potatoes.
Step 5: Cover and refrigerate for at least 2 hours, or preferably overnight, to allow flavors to meld. Stir gently before serving.
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 for maintaining that beautiful green color and crisp texture.
This salad is perfect for making ahead – it actually improves in flavor as it sits in the refrigerator. It’s an excellent alternative to hot vegetable sides when you want something cool and refreshing.
For extra flavor, try adding some chopped hard-boiled eggs or substituting some of the mayonnaise with Greek yogurt for a tangier, lighter version. The creamy dressing also works wonderfully with other vegetable combinations if you want to experiment.
FAQ
How long does this salad keep in the refrigerator?
This salad will keep well for 3-4 days when stored in an airtight container in the refrigerator.
Can I use frozen green beans?
Fresh green beans are recommended for the best texture, but you can use frozen if necessary. Thaw them completely and pat dry before using.
What type of potatoes work best?
Yukon Gold or red potatoes work best as they hold their shape well after cooking. Russet potatoes tend to become too mushy.
