Sweet Potato Salad Recipe With Greek Yogurt: Roasted Sweetness Meets Tangy Yogurt Cream

This sweet potato salad recipe with Greek yogurt transforms humble ingredients into a vibrant, creamy dish that balances earthy sweetness with tangy brightness. The roasted sweet potatoes develop a caramelized depth that pairs perfectly with the cool, protein-rich Greek yogurt dressing—creating a texture that's both velvety and satisfying.

What makes this version stand out is how the yogurt replaces mayo without sacrificing richness, while fresh herbs and citrus add layers of freshness that keep every bite interesting.

The process is simpler than you'd expect: roast the sweet potatoes until tender and caramelized, then toss them with a dressing made from Greek yogurt, lemon juice, and a touch of honey for balance.

I've tested this recipe countless times to ensure the sweet potatoes stay moist while absorbing the creamy dressing beautifully. The result is a salad that's hearty enough to serve as a main dish but light enough for a refreshing side.

What you'll end up with is a salad that's visually stunning—golden sweet potatoes against a creamy base, topped with fresh herbs and toasted nuts for texture.

The flavor profile is complex yet harmonious: caramelized sweetness from the roasted potatoes, tangy brightness from the yogurt and lemon, and subtle crunch from the toppings. It's the kind of dish that feels special enough for company but simple enough for weeknight dinners.

This salad keeps well in the refrigerator for up to four days, making it perfect for meal prep. Serve it warm or at room temperature, and don't be afraid to customize it with your favorite herbs, nuts, or even a sprinkle of chili flakes for heat.

The possibilities are endless, but the foundation is foolproof—once you try this version, you'll never go back to the traditional mayo-based sweet potato salad again.

Ingredients for sweet potato salad recipe with greek yogurt

Roasted sweet potatoes meet creamy Greek yogurt for a salad that's hearty yet refreshing—no mayo needed.

The sweet potatoes are the star here, so pick firm ones with smooth skins—Trader Joe's or Whole Foods carry the best varieties. Roast them until caramelized (about 30 minutes at 400°F) for that deep, earthy flavor. For the Greek yogurt, Fage 5% or Siggi's full-fat work best—they're thick enough to coat the potatoes without making the salad soggy. I always grab extra because it keeps for 2 weeks in the fridge, and you'll want it for other recipes too.

No honey? Maple syrup works just as well, though it has a different flavor profile. Fresh herbs wilt fast, so grab them last—Costco or local farmers markets have the freshest. Want more crunch? Toasted walnuts or candied pecans are great swaps. The cinnamon is subtle but adds warmth—skip it if you prefer a more neutral flavor. For the olive oil, California extra-virgin brands like Corto or Bertolli elevate the dish without overpowering the sweet potatoes.

This salad tastes even better the next day as flavors meld—store in an airtight container for up to 4 days. The yogurt dressing separates a bit, so give it a stir before serving. For meal prep, roast a big batch of sweet potatoes and store them separately; toss with dressing just before eating. The pecans stay crisp for 1 week if kept in a sealed container, so toast extra if you're making this often.

Step-by-step instructions for sweet potato salad with Greek yogurt

This salad brings together roasted sweet potatoes with a creamy yogurt dressing - here's how to make it shine.

Preheat your oven to 400°F and line a large baking sheet with parchment paper. Toss the 2 lbs sweet potatoes with 0.25 cup extra-virgin olive oil, 1 tsp salt, and 0.25 tsp cinnamon until evenly coated. Spread them in a single layer, leaving space between each piece for even browning.

Roast for 30-35 minutes, flipping halfway through, until the edges are deep golden brown and the sweet potatoes are tender when pierced with a fork. Let them cool slightly before handling - they'll be hot! The caramelization at this stage creates that perfect sweetness that makes this salad special.

While the sweet potatoes roast, combine 1 cup plain Greek yogurt, 0.5 cup lemon juice, 2 tbsp honey, 0.5 tsp salt, and 0.5 tsp ground black pepper in a medium bowl. Whisk until smooth and well incorporated. The dressing should be thick but pourable - if it's too thick, add 1-2 tablespoons water to reach your desired consistency.

In a small separate bowl, finely mince the 3 garlic cloves and set aside. You'll add these to the dressing just before combining with the sweet potatoes to preserve their fresh flavor. The tangy yogurt and bright lemon create the perfect balance to the sweet roasted potatoes.

Once the sweet potatoes have cooled slightly, cut them into 1-inch chunks and transfer to a large serving bowl. Add the yogurt dressing and gently toss until everything is evenly coated. Fold in the minced garlic cloves, 0.5 cup chopped fresh parsley, and 0.25 cup chopped fresh mint leaves (if using). The herbs will add a fresh brightness that cuts through the richness of the yogurt.

Taste and adjust seasoning if needed - you might want to add a bit more salt or lemon juice to balance the sweetness. This is where you can customize the salad to your preference while keeping all the original ingredients intact.

Just before serving, fold in the 0.5 cup toasted pecans to add texture and nutty depth. The pecans should be cool but still slightly warm from toasting. I like to toast them separately in a dry skillet over medium heat for 3-4 minutes until fragrant and lightly browned, then chop them coarsely.

Serve immediately while the sweet potatoes are still warm for the best texture contrast. This salad holds up well for 2-3 hours in the refrigerator if needed, but the pecans will be crispest when freshly added. The combination of warm sweet potatoes, creamy yogurt, fresh herbs, and crunchy pecans makes this a truly satisfying dish.

Dietary considerations for this dish

Dairy-Free Swaps

If you need to avoid dairy, swap the Greek yogurt for unsweetened coconut yogurt or cashew cream (blend 1 cup soaked cashews with ½ cup water until smooth). Both add creaminess without dairy, though coconut yogurt has a slight tropical note that pairs beautifully with the sweet potatoes.

For extra protein, use silken tofu blended with lemon juice—it mimics yogurt's texture while keeping the salad hearty. 🥥

Gluten-Free Assurance

This recipe is naturally gluten-free since it relies on fresh ingredients and simple spices. Always check your honey and cinnamon labels to ensure they're certified gluten-free, as some brands process in shared facilities.

For extra caution, use pure maple syrup instead of honey and organic cinnamon from brands like Frontier Co-op, which guarantees gluten-free processing. The salad's base ingredients are inherently safe for gluten-sensitive diets.

Lower-Carb Adaptations

To reduce carbs, swap half the sweet potatoes for cauliflower florets—roast them alongside the sweet potatoes for a similar texture. Use 1 cup cauliflower per 1 lb sweet potatoes to maintain structure.

For the dressing, keep the Greek yogurt but reduce honey to 1 tbsp and add 1 tsp Dijon mustard for depth. This version drops net carbs by about 30 grams per serving while keeping the creamy satisfaction. 🥦

Protein Boost Options

Add ½ cup cooked chickpeas or ¼ cup crumbled feta cheese (if dairy isn't an issue) to boost protein. For a meaty option, fold in ½ cup grilled chicken breast or ¼ cup smoked turkey after roasting the sweet potatoes.

These additions turn the salad into a complete meal with 15-20 grams protein per serving—perfect for post-workout or high-protein days. The Greek yogurt already contributes 12 grams protein per cup, so you're getting a double protein punch!

Nut-Free Considerations

Skip the pecans and replace them with toasted pumpkin seeds or crispy chickpeas for crunch. For pumpkin seeds, toast ½ cup seeds in a dry skillet for 3-4 minutes until golden.
