Salads
This white and sweet potato salad recipe transforms humble ingredients into a creamy, crunchy masterpiece that balances sweet and tart flavors perfectly.
The secret lies in cooking the potatoes just until tender—sweet potatoes caramelize slightly while white potatoes stay firm—then tossing them with crisp celery, tangy red onion, and fresh herbs for texture and brightness.
I developed this recipe after realizing how often potato salads fell flat, either too starchy or lacking depth.
The magic happens in the dressing—a creamy blend of mayo and buttermilk with a touch of Dijon mustard for tang, plus a splash of apple cider vinegar to cut through the sweetness.
Adding diced celery and fresh parsley not only brightens the dish but also creates that satisfying crunch between bites. This salad holds its shape beautifully, making it perfect for potlucks or meal prep.
What makes this recipe stand out is the harmony of textures: tender potatoes, crisp celery, and creamy dressing come together in every forkful. The sweet potatoes add natural sweetness while the white potatoes provide a neutral base, allowing the herbs and dressing to shine.
It’s hearty enough to serve as a main dish but light enough for a side—ideal for summer gatherings or weeknight dinners.
For a vegan adaptation, simply swap the mayo for a plant-based alternative and use coconut yogurt instead of buttermilk. The same techniques apply, ensuring the same creamy texture and balanced flavors. Let’s get cooking—this salad is a game-changer for any table.
Ingredients for white and sweet potato salad
Transform humble potatoes into a creamy, crunchy masterpiece with these carefully balanced ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Peeled, cubed into 1-inch pieces |
| White Potatoes 🥔 | 1 ½ lbs | Yukon Gold preferred, cubed even |
| Mayonnaise 🥫 | ½ cup | High-quality, full-fat preferred |
| Buttermilk 🥛 | ¼ cup | Plain, not low-fat |
| Dijon Mustard 🍯 | 1 tbsp | For tangy depth |
| Apple Cider Vinegar 🍎 | 1 tbsp | Bragg preferred for flavor |
| Celery Stalk 🧅 | 2 whole | Diced into 1/4-inch pieces |
| Red Onion 🧅 | ¼ cup | Finely diced, tangy variety |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Olive Oil 🫒 | 2 tbsp | For tossing, extra-virgin |
| Granulated Sugar 🍚 | 1 tbsp | Light brown preferred for depth |
The potatoes are the foundation—Yukon Golds for their buttery texture and orange sweet potatoes for natural sweetness. Look for firm, unblemished tubers at Whole Foods or your local market’s produce section. Sweet potatoes should be firm with no soft spots, while white potatoes should be waxy (not starchy) for that perfect bite. If using store-bought baby potatoes, halve them lengthwise for even cooking. The Dijon mustard here is non-negotiable—it provides the tang that cuts through the sweetness without overpowering the delicate flavors. For extra depth, consider adding a pinch of smoked paprika to the dressing mix.
No buttermilk? Plain yogurt thinned with a splash of milk works perfectly—just add 1 tablespoon of milk per 1/4 cup yogurt. The mayonnaise should be full-fat for that luxurious creaminess (duck fat mayo if you're feeling fancy). Running short on fresh parsley? Dill or chives add a lovely brightness—just reduce the amount by half since they're more potent. The apple cider vinegar adds subtle complexity; if you only have white vinegar, reduce to 1 teaspoon and add an extra 1/2 teaspoon of sugar to balance the sharpness. For a vegan adaptation, swap the mayo for vegan mayo and the buttermilk for coconut yogurt—the texture remains identical when using full-fat versions.
Potatoes should be cooked just until tender—about 12-15 minutes in boiling water with a pinch of salt. Drain immediately and shock in ice water for 2 minutes to halt cooking and preserve their texture. This salad keeps beautifully for 4-5 days in the fridge, though the celery and herbs will soften after 2 days—refresh with extra olive oil and a sprinkle of salt before serving. For meal prep, store components separately: dress the potatoes and vegetables first, then mix with the dressing just before serving to maintain that satisfying crunch. Portion into airtight containers with parchment paper between layers to prevent sogginess.

Step-by-step instructions for white and sweet potato salad
Transform simple ingredients into a creamy, vibrant salad with perfect texture and balanced flavors.
Parboil the Potatoes for Uniform Cooking
Fill a large pot with enough water to generously cover the potatoes and bring to a rolling boil. Add the 2 lbs sweet potatoes and 1.5 lbs white potatoes (pre-cut as specified) to the boiling water. Cook for 8-10 minutes until the potatoes are fork-tender but still hold their shape when pierced with a knife.
This partial cooking ensures the potatoes finish perfectly when tossed in the dressing later. Drain immediately in a colander and rinse under cold water to stop the cooking process and cool the potatoes. The contrast between the warm potatoes and cold water also helps set their texture for the final salad.
Create the Creamy Herb Dressing
In a medium bowl, whisk together the 0.5 cup mayonnaise, 0.25 cup buttermilk, 1 tbsp Dijon mustard, 1 tbsp apple cider vinegar, 1 tbsp granulated sugar, 1.5 tsp salt, and 0.5 tsp black pepper until completely smooth and well combined. This dressing forms the creamy base that binds all ingredients together.
The buttermilk adds subtle tanginess while balancing the richness of the mayonnaise, and the sugar enhances the natural sweetness of the potatoes. Taste and adjust seasoning if needed—this is your flavor foundation, so don't skip this step.
Toss Potatoes with Dressing and Vegetables
Transfer the cooled potatoes to a large mixing bowl. Drizzle with 2 tbsp olive oil and toss gently to coat evenly. Add the 2 whole celery stalks (finely diced), 0.25 cup red onion (finely diced), and 0.25 cup fresh parsley (chopped). Pour the dressing over the potatoes and mix thoroughly with your hands or a large spoon.
This is where the magic happens—the olive oil helps distribute the dressing evenly, while the celery and onion add fresh crunch. The parsley not only brightens the salad visually but also provides a fresh herbal note that complements the creamy dressing.
Chill and Develop Flavors
Cover the bowl and refrigerate the salad for at least 2 hours, or preferably overnight. This chilling time allows the flavors to meld together and the potatoes to absorb the dressing fully. The salad will thicken slightly as it cools, which is perfect for serving.
Don't skip this step—it's essential for achieving the ideal texture and flavor balance. The potatoes will become more tender, the dressing will emulsify better, and the overall taste will be more cohesive. When ready to serve, give it a final toss to redistribute any settled dressing.
Pro Tips For Making White And Sweet Potato Salad
- Cook Potatoes Separately: Sweet potatoes and white potatoes behave differently when cooked—one gets mushy, the other stays firm. Boil the white potatoes in salted water until tender (about 12-15 minutes), then drain and cool. Roast the sweet potatoes at 400°F (200°C) for 20-25 minutes with olive oil and salt until caramelized. Mixing them raw or undercooked ruins the texture.
- Peel After Cooling: I learned this the hard way—peeling hot sweet potatoes turns them into a sticky mess. Let them cool slightly after roasting, then peel under running water. For white potatoes, peel them raw before boiling to save time, but don’t skip rinsing off excess starch—it’ll make your salad gummy.
- Balance the Dressing: Too much mayo? The salad turns heavy. Too little buttermilk? It’s bland. Start with a 3:1 ratio of mayo to buttermilk (about ¾ cup mayo, ¼ cup buttermilk per 2 cups potatoes), then adjust. Add 1-2 teaspoons of Dijon mustard first—it brightens the flavors before you even taste it.
- Cut Uniformly, Toss Early: Chop both potatoes into even ½-inch cubes—this ensures they cook at the same rate and mix well. Toss the warm potatoes with half the dressing while they’re still hot (about 10 minutes after cooking), then let them cool completely before adding the rest. This keeps them from turning to glue.
Serving suggestions for this white and sweet potato salad
Plating for Potlucks
For gatherings, serve this salad in a large glass bowl with a wooden spoon for easy scooping—it’s both practical and visually appealing. I love using amber-tinted bowls to make the orange sweet potatoes pop against the creamy dressing.
Garnish with extra chopped parsley and a sprinkle of flaky sea salt right before serving to elevate the presentation. 🌟
Bread Pairings
This hearty salad pairs perfectly with crusty sourdough or baguette slices for dipping. Toast the bread lightly and rub with a garlic clove for extra flavor. For a more substantial meal, serve alongside grilled chicken breast or smoked salmon—the creamy salad balances rich proteins beautifully. 🥖
Summer Picnic Ideas
Pack individual portions in mason jars with the dressing on the bottom, followed by potatoes, celery, and onion. Seal tightly and store upright in a cooler for up to 4 hours.
At the picnic, shake to redistribute the dressing and serve with chilled lemonade or sparkling water for a refreshing contrast. 🧺
Holiday Side Dish
Transform this salad into a festive centerpiece by arranging it on a platter with edible flowers (like nasturtiums) and a drizzle of balsamic glaze. The sweet-tart balance makes it a crowd-pleaser for Thanksgiving or Christmas dinners. Serve with roasted turkey or ham for a complete meal. 🎄
Meal Prep Containers
Divide the salad into airtight glass containers with parchment paper between layers to prevent sogginess. Store in the fridge for up to 5 days—just give it a quick toss with extra olive oil before serving.
This makes it ideal for lunches or quick dinners when you’re short on time. 📦
Dessert Twist
For a sweet finish, top individual servings with toasted pecans and a drizzle of honey—the salty-sweet contrast is unexpected but delicious. Serve with vanilla ice cream for a deconstructed dessert salad that’s perfect for summer parties. 🍯

Frequently asked questions
Why do you use both sweet and white potatoes in this salad?
The combination creates a perfect balance of flavors and textures. Sweet potatoes add natural sweetness and a slightly caramelized depth when cooked, while white potatoes (like Yukon Gold) stay firm and buttery, providing a neutral base. This contrast makes every bite more interesting than a single-potato salad.
Can I make this salad ahead of time?
This salad actually tastes better after chilling for 2-4 hours (or overnight). The flavors meld together, and the potatoes absorb the dressing perfectly. Just store it in an airtight container with parchment paper between layers to keep the celery crisp. Refresh with extra olive oil before serving.
How do I prevent the celery from getting soggy?
Salting the celery before adding it to the salad is key—toss the diced celery with 1/4 teaspoon salt and let it sit for 10 minutes before mixing. This draws out moisture, keeping it crisp. Also, store the salad in layers with parchment paper between them to prevent sogginess.
What's the best way to make this vegan?
Swap the mayo for vegan mayo (like Hellmann's Vegan) and replace buttermilk with coconut yogurt (thinned with 1 tablespoon of plant-based milk per 1/4 cup). The texture stays creamy, and the flavors remain balanced. Just check that your vegan mayo has enough fat for that rich mouthfeel.
Can I use baby potatoes instead of cutting regular potatoes?
Yes! Halve baby potatoes lengthwise before cooking to ensure even doneness. They'll cook faster than regular potatoes, so reduce the boiling time to 6-8 minutes instead of 8-10. This works especially well for white potatoes, which stay firm when cooked properly.
