Salads
This sweet potato and white potato salad recipe transforms humble tubers into a vibrant, textured dish where caramelized sweetness meets crisp celery crunch.
The secret lies in roasting the sweet potatoes first—just 20 minutes at 400°F—to develop their natural sugars into a golden, almost candy-like sweetness while keeping the white potatoes tender and neutral.
I developed this after years of struggling with soggy potato salads; the roasting method ensures each bite stays satisfyingly firm.
The dressing is where the magic happens: a tangy mustard-vinaigrette base cuts through the richness of the potatoes while herbs and a touch of honey balance the flavors. Celery and red onion add the signature crunch, but it's the contrast between the deep caramelized sweet potatoes and the crisp white potatoes that makes this salad unforgettable.
This isn't just a side dish—it's a hearty, flavor-packed meal that holds up for picnics, potlucks, or a satisfying weeknight dinner.
What you'll end up with is a salad that's visually stunning—deep oranges and creamy whites layered with bright green celery—and packed with texture. The roasted sweet potatoes develop a subtle crispness on the edges, while the white potatoes stay tender.
The dressing clings perfectly, creating a harmonious blend of sweet, tangy, and herby notes in every bite. It's the kind of dish that disappears quickly, leaving everyone asking for seconds.
Serve it warm or at room temperature for maximum flavor development, and don't be afraid to customize with add-ins like crispy bacon, toasted pecans, or fresh herbs. The possibilities are endless, but the foundation—those perfectly roasted potatoes and bright dressing—is what makes this salad truly special. Let's get started!
Ingredients for sweet potato and white potato salad
Roasted sweet potatoes meet crisp white potatoes in this vibrant, textured salad where caramelized sweetness and fresh crunch shine.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 ½ lb | Medium, peeled and cubed |
| White Potatoes 🥔 | 2 lb | Yukon Gold, peeled and cubed |
| Celery Stalks 🧅 | 4 whole | Thinly sliced, about 2 cups |
| Red Onion 🧅 | 1 medium | Thinly sliced, about 1 cup |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For roasting potatoes |
| Honey 🍯 | 2 tbsp | For glaze and dressing |
| Dijon Mustard 🥫 | 2 tbsp | For tangy dressing base |
| Apple Cider Vinegar 🍎 | ¼ cup | For dressing acidity |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for freshness |
| Fresh Thyme 🌿 | 1 tbsp | Chopped, for herbal notes |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Cloves 🧄 | 3 cloves | Minced for dressing |
The sweet potatoes are the star here—organic sweet potatoes from Trader Joe's develop the best caramelization, but any medium variety works. For white potatoes, Yukon Gold stays creamy without falling apart. Peeled and cubed evenly, they roast to tender perfection while the sweet potatoes develop that signature crisp edge. If you're short on time, pre-cut frozen sweet potatoes thawed and patted dry work in a pinch, though fresh is ideal. The key is roasting them separately: sweet potatoes first for 20 minutes, then white potatoes for 15 minutes—this prevents the white potatoes from turning mushy.
No Dijon mustard? Whole-grain mustard at double the amount works, though the texture will differ slightly. Fresh herbs wilt fast, so dried thyme at one-third the amount is a solid backup. The honey can be swapped for maple syrup or agave, though it adds a deeper earthiness. For extra crunch, toasted pecans or candied walnuts elevate the dish—just add them after tossing. The red onion adds brightness, but if you prefer milder flavor, yellow onion at half the amount is gentler. Celery should be crisp; if it feels rubbery, soak it in ice water for 10 minutes before slicing.
Roasted potatoes keep their texture best when stored in an airtight container for 4-5 days in the fridge. The dressing separates naturally—just whisk before serving. For make-ahead convenience, roast the potatoes and store them separately, then toss with dressing when ready. The full salad holds up well for 3 days refrigerated, though the celery and herbs lose crispness over time. For longer storage, freeze the roasted potatoes (without dressing) for up to 3 months. Reheat gently in the oven to restore crispness before serving.

Step-by-step instructions for sweet potato and white potato salad
This method delivers perfectly caramelized sweet potatoes alongside crisp white potatoes, all bound together with a bright, herby dressing.
Roast the Potatoes for Maximum Flavor
Preheat your oven to 425°F and line two rimmed baking sheets with parchment paper. Toss the 2.5 lb cubed sweet potatoes and 2 lb cubed white potatoes separately with 1 tbsp of the extra-virgin olive oil, ½ tsp salt, and ¼ tsp black pepper each. Spread them in a single layer—they need room to caramelize, not steam.
Roast the sweet potatoes for 35-40 minutes until tender with deep caramelization and crisp edges. Remove them and set aside. Increase the oven temperature to 450°F, then roast the white potatoes for 25-30 minutes until golden brown and crispy. The contrast between the sweet, caramelized sweet potatoes and the crisp white potatoes is what makes this salad special.
Prepare the Celery and Onion for Crunch
While the potatoes roast, thinly slice the 4 whole celery stalks (about 2 cups) and 1 medium red onion (about 1 cup). Place them in a large bowl and toss with 1 tbsp of the extra-virgin olive oil, ½ tsp salt, and ¼ tsp black pepper. Let them sit at room temperature while you finish the dressing—this allows their flavors to meld slightly before assembly.
Real talk: Don't skip the salt here. It draws out moisture from the celery and onion, making them crispier when combined with the warm potatoes. If you're short on time, you can briefly sauté them in a dry pan for 2-3 minutes to enhance their crunch, but raw works perfectly too.
Create the Honey-Dijon Dressing
In a small bowl, whisk together the 2 tbsp Dijon mustard, 2 tbsp honey, 3 minced garlic cloves, 0.25 cup apple cider vinegar, and the remaining 0.25 cup extra-virgin olive oil. Season with ½ tsp salt and ¼ tsp black pepper. The dressing should be thick but pourable—if it's too stiff, whisk in 1-2 tsp water to loosen it.
Taste and adjust the balance: More vinegar for tang? A touch more honey for sweetness? This dressing ties everything together, so don't rush it. The honey and Dijon mustard create a perfect contrast to the earthy potatoes, while the vinegar brightens the dish. Let it sit for 5 minutes to allow the flavors to meld before using.
Assemble and Chill for Best Texture
In a large serving bowl, combine the roasted sweet potatoes, white potatoes, celery, and red onion. Pour the dressing over everything and toss gently but thoroughly to coat. Fold in the 0.25 cup chopped fresh parsley and 1 tbsp chopped fresh thyme, distributing them evenly throughout the salad. The herbs add a fresh, aromatic finish that cuts through the richness of the roasted vegetables.
Cover the bowl and refrigerate for at least 1 hour (or up to 4 hours) before serving. This chilling time is crucial—it allows the flavors to develop fully and ensures the potatoes stay warm and the celery remains crisp. If you're in a hurry, serve at room temperature, but the texture and flavor will be even better after chilling.
Serve with Confidence
Before serving, give the salad one final toss to redistribute the dressing and herbs. The contrast in textures—crisp white potatoes, tender sweet potatoes, and crunchy celery—should be evident in every bite. Garnish with additional fresh parsley if desired, and serve with a side of crusty bread to soak up any extra dressing.
This salad holds up beautifully for 2-3 days in the refrigerator, making it an ideal make-ahead dish for gatherings. The flavors deepen as it sits, and the potatoes maintain their perfect texture. Enjoy it as a hearty side dish or a light main course with a simple green salad on the side.
Pro Tips For Making Sweet Potato And White Potato Salad
- BOIL THEM TOGETHER: Peel and chop both potatoes the same size—about 1-inch cubes—then toss them in the same pot with cold water and a pinch of salt. Sweet potatoes take longer, so starting them together guarantees even cooking without mushy white potatoes or undercooked orange ones. (Yes, even if you’re impatient like me, resist the urge to check them early.)
- PEEL AFTER COOLING: Skip peeling raw sweet potatoes—their skins stay stubbornly attached when hot. Let them cool completely after boiling, then peel under running water for a cleaner, faster process. Red onions and celery don’t need this treatment, but the sweet potatoes will thank you.
- DICE ONION AND CELERY SMALL: Cut the red onion and celery into ¼-inch pieces, not the usual ½-inch chunks. This ensures even distribution of flavor and texture, so every bite has that bright crunch and sharpness. (I learned this the hard way—uneven pieces make for a salad that’s hit-or-miss.)
- DRESS WHILE STILL WARM: Toss the drained potatoes with olive oil and any other dressing while they’re still slightly warm—about 105°F (40°C). The residual heat helps the oil cling better, and the salad stays cohesive longer. Cold potatoes? They’ll repel dressing like a bad roommate.

Frequently asked questions
Why roast sweet potatoes separately from white potatoes?
Roasting them separately gives you perfect texture contrast: sweet potatoes develop deep caramelization and crisp edges at 425°F for 35-40 minutes, while white potatoes stay tender and crispy at 450°F for 25-30 minutes. Cooking them together would make the white potatoes mushy while the sweet potatoes overcook. This method ensures each bite delivers that satisfying crunch and tenderness balance.
Can I make this salad ahead of time?
Roast the potatoes up to 3 days ahead and store them separately in an airtight container. When ready to serve, toss with fresh dressing and herbs. The flavors actually improve overnight as the potatoes absorb the dressing. For best texture, chill for at least 1 hour before serving to maintain crispness.
What's the best way to cut potatoes for even cooking?
Cut both sweet and white potatoes into 1.5-inch cubes for consistent cooking. Use a sharp chef's knife and work on a stable cutting board. For extra safety, cut the potatoes in half lengthwise first, then slice into cubes. This ensures even exposure to heat and prevents some pieces from cooking faster than others.
How can I make this salad more protein-packed?
Add ½ cup cooked chickpeas or ½ cup crumbled bacon to the salad. For a heartier option, stir in 1 cup shredded rotisserie chicken or ½ cup canned tuna (drained). These additions boost protein while adding different textures and flavors that complement the sweet and savory potato base.
What if my celery gets too soft?
If your celery loses crispness, try slicing it thinner than usual and tossing it with the potatoes just before serving. For extra crunch, add 2 tbsp chopped toasted pecans or ¼ cup diced bell pepper to replace some of the celery. The key is to keep the celery cold until the last minute to maintain its texture.
