How to Make Buttermilk Smashed Potato Salad | Creamy BBQ Side for Memorial Day
- Boil the Potatoes: Start by washing the 3 lbs of Yukon gold baby potatoes. Place them in a large pot, covering them with cold water and adding a good pinch of sea salt. Bring to a boil and cook until fork-tender, about 15-20 minutes. This crucial step ensures the potatoes are soft enough to smash later.
- Preheat the Oven: While the potatoes are cooking, preheat your oven to 425°F. This high temperature is key to achieving that crunchy, golden finish on the potatoes.
- Smash the Potatoes: Drain the potatoes and lay them out on a baking sheet lined with parchment paper. Using the bottom of a glass, gently smash each potato until slightly flattened but still intact. This little trick increases the surface area for roasting!
- Roast the Potatoes: Drizzle the smashed potatoes with 2 tablespoons of extra virgin olive oil, ensuring to brush it all over. Season generously with flaky sea salt, then roast them in the oven for 15-20 minutes, or until they turn golden brown and crispy. Keep a close eye on them for that “just right” crunch!
- Make the Dressing: In a large mixing bowl, whisk together the ⅓ cup mayonnaise, ⅓ cup Greek yogurt, 1 tablespoon Dijon mustard, 1 tablespoon apple cider vinegar, ¼ cup chopped parsley, ⅓ cup chopped green onions, 1 tablespoon dill, ½ teaspoon flaky sea salt, and ⅓ teaspoon pepper. This creamy dressing is where the magic happens, blending all those flavors together beautifully.
- Combine and Chill: Once the potatoes are done roasting, let them cool slightly, then chop them into bite-sized pieces; mix in both large and small chunks for a beautiful texture. Add the crispy potatoes to the dressing and toss gently to coat. This step infuses the potatoes with all those creamy flavors!
- Chill Before Serving: Refrigerate the potato salad for at least 30 minutes to allow the flavors to meld. When ready to serve, transfer it to a nice serving dish and, if you wish, garnish with additional chopped herbs. This dish is delightful served at room temperature, making it easy for your guests.
Storing & Reheating
To keep your Buttermilk Smashed Potato Salad fresh, store it in an airtight container in the refrigerator. It will stay good for about three to five days. If you happen to have leftovers, feel free to freeze the salad for up to three months. When it’s time for a reheat, gently warm it in the oven at 350°F for about 10-15 minutes; however, please note the texture might soften slightly. To revive its flavor, consider adding a splash of vinegar or fresh herbs right before serving.
Chef’s Helpful Tips
- Avoid Overcooking: When boiling your potatoes, ensure they’re just fork-tender to prevent them from becoming mushy.
- Room Temperature Ingredients: For an even creamier dressing, let your mayonnaise and Greek yogurt sit at room temperature while you prepare the potatoes.
- Texture Check: If your potatoes come out too crispy or hard, you can briefly steam them to soften them up before mixing them into the dressing.
- Flavor Boost: Experiment with additional herbs or spices in the dressing, like smoked paprika or garlic powder, for an extra flavor punch.
The beauty of Buttermilk Smashed Potato Salad lies not just in its comforting flavors but also its versatility.
