How to Make Buttermilk Smashed Potato Salad | Creamy BBQ Side for Memorial Day
- Prep the Potatoes: Wash the 3 lbs of yukon gold baby potatoes and place them in a large pot. Cover with cold water and add a good pinch of sea salt. Bring to a boil and cook until fork-tender, about 15-20 minutes.
- Roast the Potatoes: Preheat your oven to 425°F. Drain the potatoes and transfer them to a baking sheet lined with parchment paper. Using the bottom of a glass, gently smash each potato until slightly flattened but still intact. Drizzle with 2 tablespoons of extra virgin olive oil and brush to evenly coat. Season with flaky sea salt. Roast in the oven for 15-20 minutes or until golden brown and crispy.
- Prepare 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.
- Combine & Chill: Once the potatoes are done roasting and have cooled slightly, chop them into bite-sized pieces, leaving some larger and some smaller for texture. Add the crispy potatoes to the bowl with the dressing and gently toss to coat everything evenly. For the best flavor, chill the salad in the fridge for at least 30 minutes before serving.
- Serve: When you’re ready to serve, transfer the salad to a serving dish and garnish with additional herbs if desired. Serve at room temperature for the ultimate flavor experience.
Storing & Reheating
To store, keep your Buttermilk Smashed Potato Salad covered in the fridge, where it lasts for about three days. If you need longer storage, consider freezing it in an airtight container for up to three months; however, note that the texture may change slightly. To refresh it, simply let it thaw in the fridge overnight and give it a good stir before serving. Enjoy it at room temperature or chilled, but remember that flavors develop even more after a day in the fridge!
Chef’s Helpful Tips
- Ensure your potatoes are similar in size for even cooking; this helps with consistent texture.
- Roasting the potatoes at a high temperature is key to achieving that delicious crispiness.
- Mix the dressing just before combining with the potatoes to prevent them from becoming soggy.
- For added zest, try sprinkling the finished salad with some smoked paprika or a squeeze of fresh lemon juice.
- If making ahead of time, consider adding the green onions just before serving for that fresh crunch.
With the vibrant mix of flavors and textures, Buttermilk Smashed Potato Salad is guaranteed to be a hit at any gathering. The creamy dressing, enhanced by herbs and spices, truly complements the crispy potatoes for a lovely dish that’s sure to impress your guests.

Recipe FAQs
Can I use other types of potatoes?
Absolutely! While yukon golds are fantastic for their creamy texture, you can also use red potatoes or even russets. Just keep in mind that different potatoes can yield different textures.
What can I substitute for mayonnaise?
If you’re looking for a lighter version or a dairy-free option, you could substitute mayonnaise with additional Greek yogurt or use an avocado-based mayo. Both give a creamy texture, just with varying flavors.
How can I make this dish vegan?
To make this recipe vegan, use dairy-free mayo and replace the Greek yogurt with a plant-based yogurt. Always check the labels to ensure they’re free from animal products.
Can I prepare this potato salad in advance?
Yes, you can! The flavors of your buttermilk smashed potato salad deepen after sitting in the fridge. Preparation a day ahead makes for a quicker serving on the day of your barbecue or gathering. Just remember to add the green onions just before serving for freshness!
