Ingredients for sweet potato and white potato salad
Roasted potatoes, fresh herbs, and a bright vinaigrette make this salad creamy and satisfying without mayo.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium size, peeled and cubed |
| White Potatoes 🥔 | 2 lbs | Russet or Yukon gold, peeled and cubed |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For roasting potatoes |
| Dijon Mustard 🍯 | 2 tbsp | For tangy dressing base |
| Red Wine Vinegar 🍷 | ¼ cup | Brightens the dressing |
| Fresh Parsley 🌿 | ½ cup | Chopped, stems removed |
| Fresh Dill 🌿 | ¼ cup | Chopped, for herby crunch |
| Toasted Pecans 🥜 | ½ cup | Chopped, for texture |
| Garlic Cloves 🧄 | 3 cloves | Minced for dressing |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Honey 🍯 | 1 tbsp | Balances tangy dressing |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The potatoes are the star—sweet potatoes for caramelized sweetness and white potatoes for earthy texture. Grab organic sweet potatoes from Whole Foods or your local market for extra sweetness. Russet potatoes hold their shape best when roasted, but Yukon golds add a buttery richness. Peeled and cubed evenly (about 1.5-inch pieces), they roast to crispy perfection. For extra flavor, toss them with olive oil and a pinch of salt before roasting—that's where the magic happens.
No Dijon mustard? Yellow mustard works in a pinch, but the tang is key here. Fresh herbs are non-negotiable—dried just won’t cut it. If you’re out of dill, substitute with chives or tarragon, but parsley is the backbone. Toasting your own pecans? Spread them on a baking sheet at 350°F for 8-10 minutes—they’ll smell amazing. Short on time? Store-bought toasted pecans from Trader Joe’s are a lifesaver. The honey and lemon juice balance the vinegar perfectly, so don’t skip them—trust me, it’s worth it.
This salad keeps beautifully for 4-5 days in the fridge, so make a big batch. Store the dressing separately if you’re prepping ahead—toss it just before serving to keep the herbs crisp. For extra crunch, add the toasted pecans right before eating. The flavors actually improve overnight as the potatoes soak up the dressing. Pack it for lunches—it’s the ultimate meal-prep side that tastes fresh every time.

Step-by-step instructions for sweet potato and white potato salad
This creamy, herb-packed salad delivers rich flavor without mayo—here's how to make it shine.
🔥 Step 1: Roast the Potatoes Until Tender and Golden
Preheat your oven to 425°F and line two large baking sheets with parchment paper. Toss the 2 lbs cubed sweet potatoes and 2 lbs cubed white potatoes with ½ cup extra-virgin olive oil and 1.5 tsp salt. Spread them in a single layer—don't crowd the pan, or they'll steam instead of roast.
Roast for 30-35 minutes, flipping the potatoes halfway through, until they're fork-tender with deep golden brown edges. The sweet potatoes should caramelize beautifully while the white potatoes stay firm. Let them cool slightly before handling—they'll be hot!
👨🍳 Step 2: Prepare the Herb-Dressing Base
While the potatoes roast, whisk together 2 tbsp Dijon mustard, ¼ cup red wine vinegar, 1 tbsp honey, 1 tbsp lemon juice, and 3 minced garlic cloves in a bowl. Gradually drizzle in ¼ cup extra-virgin olive oil while whisking continuously to emulsify the dressing.
Season with ½ tsp black pepper and taste—this is your flavor foundation. The dressing should be tangy-sweet with a subtle garlic kick. If it looks too thick, add 1-2 tablespoons water to reach a pourable consistency. Set aside while the potatoes finish roasting.
🥘 Step 3: Assemble the Salad with Herbs and Crunch
In a large mixing bowl, combine the warm (but not scorching) roasted potatoes with ½ cup chopped fresh parsley and ¼ cup chopped fresh dill. Gently toss to distribute the herbs evenly. The heat from the potatoes will wilt the herbs slightly, intensifying their flavor.
Drizzle the herb dressing over the potatoes and toss again, working the dressing into every crevice. The potatoes should be evenly coated but still retain their texture. Here's the thing—don't overmix or you'll crush the potatoes. We want them to stay intact for that satisfying bite.
⏰ Step 4: Add Texture and Let It Rest
Fold in the ½ cup chopped toasted pecans just before serving. The warmth of the potatoes will make the pecans even more aromatic. The contrast between the creamy dressing, tender potatoes, and crunchy pecans is what makes this salad special.
Let the salad sit for 10-15 minutes before serving—this allows the flavors to meld together. The potatoes will absorb just enough dressing to become perfectly coated without turning soggy. If you're making this ahead, assemble everything except the pecans and refrigerate for up to 2 days. Add the pecans just before serving to maintain their crispness.
Pro Tips For Making Sweet Potato And White Potato Salad
- Boil Until Fork-Tender: Sweet potatoes need patience—test them at 20 minutes, but don’t rush past 25. White potatoes? They’re done when a knife glides in like butter. Overcooking turns them mushy; undercooking leaves you chewing. I learned this after serving a salad where one bite was perfect and the next was a gummy disaster.
- Peel While Still Warm: Cold potatoes are stubborn. Peel them right after draining while they’re still hot—skins slip off effortlessly. Skip the soaking step unless you’re dealing with waxy potatoes that refuse to behave. Your hands (and your salad) will thank you.
- Balance the Mustard: Start with 1 tablespoon Dijon, then taste. Too sharp? Add a splash of vinegar. Too mild? More mustard. The sweet potatoes’ natural sugars can make the dressing taste flat if you overdo it. My first batch was bland until I doubled the mustard—now I adjust as I go.
- Toss with Olive Oil First: Drizzle the warm potatoes with 1 tablespoon olive oil before adding the dressing. This coats them evenly and prevents a greasy mess when you mix later. The oil also helps the vinegar and mustard cling instead of pooling at the bottom. (Yes, even if you’re impatient like me.)
Serving suggestions for this recipe
Plating Like a Pro
For a restaurant-worthy presentation, arrange the salad in a wide, shallow bowl—this showcases the colors and textures beautifully. I love using glass bowls because they let the vibrant orange of sweet potatoes and golden white potatoes shine.
Garnish with an extra sprinkle of chopped fresh dill and a few pecan halves on top for visual appeal. 🌟
Pairing with Proteins
This salad stands up to hearty proteins, making it perfect for a complete meal. I often serve it with grilled chicken breast (seasoned with lemon and herbs) or smoked salmon for a lighter option.
The creamy texture balances the richness of proteins beautifully. For a vegetarian spread, add crumbled feta cheese or marinated white beans to boost protein content.
Summer Picnic Perfection
Pack this salad in airtight glass containers with compartments for the potatoes, dressing, and pecans separately. Keep the dressing in a small jar and toss everything together right before eating to maintain crispness.
Bring along crusty bread or warm tortillas for a complete picnic spread. The flavors taste even better when enjoyed outdoors! 🌞
Garnish Game-Changers
Elevate your salad with unexpected garnishes. A drizzle of honey-sriracha glaze adds a sweet-spicy kick, while pickled red onions bring tangy brightness. For a pop of color, add edible flowers like nasturtiums or thinly sliced radishes.
These small touches make the dish feel extra special without overpowering the main flavors.
Meal-Prep Friendly
Divide the salad into individual glass containers for easy grab-and-go lunches. Store the dressing separately and toss it in just before eating to keep the herbs fresh. I prep this salad on Sundays and portion it into mason jars—it stays fresh for 4-5 days in the fridge.
The flavors actually deepen as the potatoes absorb more dressing over time. Perfect for busy weekdays! ⏰
Seasonal Variations
In fall, swap pecans for toasted walnuts and add sautéed apples for a cozy twist. For spring, use toasted almonds and fresh peas for a lighter texture.
In winter, boost warmth with roasted butternut squash and crispy bacon bits. Each season brings new opportunities to customize this versatile salad. 🍂

Frequently asked questions
Can I use orange sweet potatoes instead of regular sweet potatoes?
Yes! Orange sweet potatoes work perfectly—they're even sweeter and more vibrant. Their natural sugars caramelize beautifully during roasting, intensifying the flavor. Just be aware they'll make the salad more visually striking with their deep orange hue.
How do I keep the white potatoes from turning mushy?
Roast them at 425°F for 30-35 minutes and flip halfway through. Use Russet potatoes (they hold shape best) and cut them into 1.5-inch cubes. Don't overcrowd the pan—give them space to crisp up. Let them cool slightly before handling.
Can I make this salad ahead of time?
Assemble everything except the pecans and store in an airtight container for up to 2 days. Add the pecans right before serving to keep them crisp. The flavors actually improve as the potatoes absorb the dressing overnight—it gets even better!
What if I don't have Dijon mustard?
Use yellow mustard as a substitute, but reduce the amount to 1 tbsp since it's milder. For extra tang, add ½ tsp apple cider vinegar to the dressing. The flavor will be slightly different but still delicious—this salad is forgiving with substitutions.
Why does the dressing separate?
This happens when the oil and vinegar aren't properly emulsified. Whisk vigorously while adding the oil, or blend the dressing ingredients for 10-15 seconds with an immersion blender. If it separates later, just give it a quick stir before serving—it'll come together again.
