- 2 tablespoons extra virgin olive oil: This adds richness and helps achieve that golden, crispy exterior when roasting.
- ⅓ cup mayonnaise: For creamy texture; choose a high-quality brand for the best flavor.
- ⅓ cup grass-fed Greek yogurt: Adds creaminess and a tangy flavor. Regular yogurt can be used in a pinch.
- ¼ cup chopped parsley: Fresh parsley brightens up the salad and adds a burst of color.
- ⅓ cup chopped green onions: They introduce a mild onion flavor and a bit of crunch.
- 1 tablespoon dill: This herb complements the potatoes beautifully; fresh dill is recommended for maximum flavor.
- 1 tablespoon apple cider vinegar: This brings a pleasantly tangy element to the dressing.

- ½ teaspoon flaky sea salt: Use this for a finishing touch on your roasted potatoes.
- ⅓ teaspoon pepper: Essential for seasoning and rounding out the flavors.
How to Make Buttermilk Smashed Potato Salad | Creamy BBQ Side for Memorial Day
- Cook the Potatoes: Begin by washing the 3 lbs of Yukon gold baby potatoes thoroughly. Place them in a large pot and cover with cold water, adding a generous pinch of sea salt. Bring to a boil and let them cook until they are fork-tender, which typically takes about 15-20 minutes.
- Preheat the Oven: While the potatoes are cooking, preheat your oven to 425°F (220°C).
- Smash the Potatoes: Drain the cooked potatoes and transfer them to a lined baking sheet. Using the bottom of a glass, gently smash each potato until it’s flattened but still intact.
- Add Olive Oil and Roast: Drizzle the smashed potatoes with 2 tablespoons of extra virgin olive oil, making sure to coat them evenly. Season generously with flaky sea salt. Roast them in the preheated oven for 15-20 minutes, or until they turn golden brown and crispy.
- Prepare the Dressing: In a large mixing bowl, whisk together 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 until well combined.
- Combine Everything: Once the potatoes are nicely roasted and slightly cooled, chop them into bite-sized pieces. I often leave some larger chunks for texture. Add the crispy potato pieces to the dressing and gently toss to ensure they are well-coated.
- Chill and Serve: For best flavor, let the salad chill in the fridge for at least 30 minutes before serving. When ready to enjoy, transfer the potato salad to a serving dish and garnish with additional herbs if desired. Serve it at room temperature for the best taste.
Storing & Reheating
To store leftover Buttermilk Smashed Potato Salad, keep it refrigerated in an airtight container. It should stay fresh for about 3-4 days. Avoid leaving it at room temperature for more than two hours to maintain its quality. If you want to keep it longer, you can freeze it for up to 3 months in a freezer-safe container; however, the texture of the potatoes may change upon thawing and reheating. When you’re ready to enjoy it again, simply thaw in the refrigerator, then gently warm in the oven at 350°F (175°C) for about 10-15 minutes. You may want to refresh the dressing with a little extra Greek yogurt or mayonnaise for extra creaminess.
Chef’s Helpful Tips
- Avoid overcooking the potatoes; they should be just fork-tender, as they will continue to cook slightly in the oven.
- For a twist, try mixing in some crumbled bacon or hard-boiled eggs for added flavor and texture.
- Use a pastry brush to evenly distribute the olive oil when roasting the potatoes, ensuring each one gets crispy.
- If you need to make this salad ahead of time, prepare the dressing and cook the potatoes a day in advance. Combine the two on the day of serving to maintain crunchiness.
- Experiment with different herbs! Chives or basil can be a delightful substitution for a unique flavor profile.
Buttermilk Smashed Potato Salad is not just easy to prepare but also a completely satisfying dish that will shine at any gathering.
