Ingredients for sweet potato and white potato salad
Roasted potatoes meet creamy herbs in this restaurant-quality salad that’s perfect for picnics or meal prep.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium size, peeled and cubed |
| White Potatoes 🥔 | 2 lbs | Yukon gold, peeled and cubed |
| Red Onion 🧅 | 1 whole | Thinly sliced, for crunch |
| Celery Stalks 🧅 | 3 whole | Diced, for freshness |
| Greek Yogurt 🥛 | 1 cup | Full-fat for creaminess |
| Dijon Mustard 🍯 | 2 tbsp | For tangy depth |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Fresh Parsley 🌿 | ½ cup | Chopped, for brightness |
| Fresh Chives 🌱 | ¼ cup | Chopped, for freshness |
| Garlic Cloves 🧄 | 3 cloves | Minced, for flavor |
| Lemon Zest 🍋 | 1 tbsp | From 1 lemon |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Honey 🍯 | 1 tbsp | For subtle sweetness |
The potatoes are the heart of this dish—Yukon golds for creaminess and sweet potatoes for depth. Costco or Trader Joe's usually carry pre-peeled sweet potatoes, which saves time. Look for firm, unblemished potatoes with vibrant color—no soft spots. The red onion adds a sharp crunch, so don’t skip slicing it thin. Celery keeps the salad fresh longer, and I always grab the crisp stalks from the grocery store’s produce section. For the herbs, fresh is non-negotiable—dried just won’t give you that same bright flavor punch.
No Greek yogurt? Vegan yogurt or sour cream works in a pinch, though the texture will be slightly different. Short on Dijon? Yellow mustard at half the amount gets you close. The olive oil matters here—California extra-virgin from the store’s refrigerated section has the best flavor. For the honey, local raw honey adds subtle floral notes, but regular grocery store honey works fine. Want more crunch? Add 1/2 cup diced bell pepper or toasted nuts. The lemon zest can be zested by hand for maximum aroma, but a microplane works too.
This salad tastes even better the next day as flavors meld. Store in an airtight container for up to 5 days in the fridge. For meal prep, portion into individual containers—1/2 cup dressing per 2 cups potatoes keeps everything balanced. The roasted potatoes reheat beautifully if you prefer them warm. Freeze the dressing separately for up to 3 months if you’re prepping ahead, then toss with fresh potatoes when ready to serve.

Step-by-step instructions for sweet potato and white potato salad
Follow these precise steps to create a perfectly balanced salad with creamy texture and vibrant flavors.
Parboil the Potatoes to Perfect Tenderness
In a large pot, bring 4 quarts of salted water to a rolling boil. Add the 2 lbs sweet potatoes and 2 lbs white potatoes (already peeled and cubed) and cook for 8-10 minutes until they're just tender when pierced with a fork. You want them to hold their shape but be easily pierced—not mushy.
Drain immediately and transfer to an ice bath to halt cooking. This parboiling step ensures your potatoes cook evenly and maintain their texture. Don't skip this cooling step—it prevents overcooking when you finish in the oven later. Once cooled, drain thoroughly and pat completely dry with paper towels.
Roast Potatoes for Caramelized Crunch
Preheat your oven to 400°F. In a large mixing bowl, toss the drained potatoes with 0.5 cup extra-virgin olive oil, 1.5 tsp salt, and 0.5 tsp black pepper until evenly coated. Spread them in a single layer on two rimmed baking sheets.
Roast for 25-30 minutes, stirring once halfway through, until the edges are golden brown and the potatoes are tender when pierced. The sweet potatoes will develop a beautiful caramelized crust while the white potatoes remain firm. Remove from oven and let cool slightly before proceeding.
Prepare the Herb-Infused Dressing
In a medium bowl, whisk together the 1 cup Greek yogurt, 2 tbsp Dijon mustard, 1 tbsp lemon zest, 1 tbsp honey, 3 minced garlic cloves, and 0.5 cup extra-virgin olive oil reserved from the potatoes. The dressing should be smooth and creamy with a subtle tang.
Stir in the 0.5 cup chopped fresh parsley and 0.25 cup chopped fresh chives until evenly distributed. Taste and adjust seasoning with additional salt or pepper if needed. This herb infusion adds freshness that balances the richness of the yogurt and roasted potatoes.
Combine All Ingredients for Perfect Balance
In a large mixing bowl, combine the warm (but not hot) roasted potatoes with 1 whole thinly sliced red onion and 3 diced celery stalks. Pour the dressing over the potatoes and gently toss until everything is evenly coated. The acidity from the lemon zest and Dijon mustard will help tenderize the onions slightly.
Let the salad sit at room temperature for 10-15 minutes before serving. This resting time allows the flavors to meld together perfectly. The potatoes will absorb just enough dressing to create that creamy texture while maintaining their individual integrity. For best results, serve immediately while the potatoes are still warm from roasting.
Pro Tips For Making Sweet Potato And White Potato Salad
- COOL THE POTATOES FIRST: I learned this the hard way—dumping hot potatoes into a cold dressing makes a soggy mess. Let them sit in a wire basket for 10 minutes after boiling, then run under cold water. The texture stays firm, and the salad won’t turn into a watery purée.
- PEEL AND CUT ONION LAST: Red onion adds bite, but it turns bitter and watery if prepped too early. Dice it right before mixing everything—just 2-3 minutes before serving. Thin slices work best; skip the chopping if you’re short on time.
- USE HALF THE YOGURT: Greek yogurt thickens fast, and too much makes the salad gluey. Start with ¼ cup per pound of potatoes, then adjust. If it’s still too thick, add a splash of buttermilk or lemon juice—it cuts the richness without thinning.
- BOIL POTATOES UNTIL FIRM: Sweet potatoes get mushy fast, but white potatoes need extra time. Test with a fork: they should hold shape but yield slightly. Overcooking turns them to mush, and no one wants a sad, gummy salad. Aim for 12-15 minutes total.
Pro cooking tips for great sweet potato and white potato salad
Roasting Perfection
Roasting is where the magic happens—don’t skip the parboiling step! Cooking the potatoes in boiling water for 8-10 minutes ensures they’re tender but still hold their shape. After draining, immediately plunge them into an ice bath to stop cooking.
This prevents mushiness when they roast later. I use 400°F for even browning, stirring once halfway through to avoid sticking. 🔥
Dressing Balance
The dressing is the soul of this salad, so taste as you go! Whisk the Greek yogurt, Dijon mustard, and honey first to emulsify, then add the olive oil slowly.
The lemon zest and garlic brighten everything, while the parsley and chives add freshness. If it’s too thick, add 1-2 tbsp water to loosen it.
Texture Control
For the perfect bite, roast the potatoes until they’re tender but still slightly firm. Over-roasting turns them dry and crumbly. If your oven runs hot, reduce the temperature to 375°F and check at 25 minutes.
The sweet potatoes should caramelize beautifully, while the Yukon golds stay creamy inside. Let them cool slightly before tossing with dressing to avoid a soggy salad.
Make-Ahead Secrets
This salad tastes even better the next day! Store the roasted potatoes and dressing separately in airtight containers for up to 5 days. When ready to serve, toss them together and let sit for 10 minutes to meld flavors.
For meal prep, portion into individual containers with ½ cup dressing per 2 cups potatoes. The flavors deepen as the onions soften and herbs infuse.
Pro Crunch Boost
Want extra texture? Add ½ cup toasted pecans or walnuts right before serving. For a smoky twist, sprinkle with ½ tsp smoked paprika when roasting. If you love heat, toss in 1 tbsp chopped jalapeño with the dressing. These tweaks keep the dish exciting while maintaining balance. ✨

Frequently asked questions
Can I substitute sweet potatoes with regular potatoes?
You can use all white potatoes, but you'll lose the natural sweetness that balances the creamy dressing. For best results, stick with the sweet potato/white potato combo—it creates a beautiful color contrast and flavor depth. If you must substitute, add 1 tbsp extra honey to the dressing to compensate for the lost sweetness.
How do I prevent the salad from getting soggy?
Roast the potatoes until they're tender but still slightly firm—over-roasting makes them crumbly. Let them cool completely before tossing with dressing, and store components separately in airtight containers. Only combine when ready to serve. The key is timing: add celery and onions just before eating for maximum crunch.
Can I make this salad ahead of time?
Roast the potatoes and make the dressing separately, then store them in airtight containers for up to 5 days. Toss them together just before serving—this lets the flavors meld beautifully. The onions will soften slightly overnight, adding sweetness. For meal prep, portion into individual containers with ½ cup dressing per 2 cups potatoes.
What's the best way to reheat leftovers?
This salad is best served at room temperature, but if you prefer warm potatoes, gently reheat in a skillet with 1 tbsp olive oil over medium-low heat for 5-7 minutes. Avoid microwaving as it makes the potatoes gummy. For cold servings, let it sit at room temperature for 10 minutes before eating to enjoy the full flavor profile.
Can I make this salad dairy-free?
Yes! Replace the Greek yogurt with 1 cup vegan yogurt or sour cream, and use ½ cup extra olive oil to maintain creaminess. For extra richness, add 1 tbsp tahini to the dressing. The texture will be slightly lighter, but the flavors remain balanced.
