Ingredients for sweet potato noodle salad
Transform simple sweet potatoes into a restaurant-quality salad with this vibrant, protein-packed recipe.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 large | Spiralized into noodles |
| Natural Peanut Butter 🥜 | ½ cup | Creamy, unsweetened preferred |
| Lime Juice 🍋 | ¼ cup | Freshly squeezed for brightness |
| Cucumber 🥒 | 1 medium | Seedless, thinly sliced |
| Red Bell Pepper 🌶️ | 1 whole | Thinly sliced into strips |
| Fresh Cilantro 🌿 | ¼ cup | Chopped, stems removed |
| Red Onion 🧅 | ¼ cup | Thinly sliced |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For roasting and dressing |
| Maple Syrup 🍯 | 2 tbsp | For dressing sweetness |
| Soy Sauce 🥢 | 2 tbsp | For umami depth |
| Sesame Seeds 🌾 | 2 tbsp | Toasted for garnish |
| Sea Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Cloves 🧄 | 3 cloves | Minced for dressing |
The sweet potatoes are the foundation—look for firm, vibrant orange ones at Whole Foods or your local market. Organic is ideal if you want to skip peeling, but conventional works too. Spiralize them just before roasting to prevent browning. For the peanut butter, natural, unsweetened varieties like 365 Organic or Smucker's ensure the best flavor without additives. The lime juice should be freshly squeezed—bottled just doesn't cut it here. If you can't find seedless cucumbers, remove the seeds yourself for cleaner slices.
No fresh cilantro? Substitute with 1/4 cup chopped parsley or skip entirely. The red bell pepper can be swapped for yellow or orange if that's what's available. For extra crunch, add 1/4 cup shredded carrots or thinly sliced jicama. The dressing can be made ahead—store it in a jar for up to 5 days in the fridge. If you prefer a smoother texture, blend the dressing ingredients instead of whisking. For heat, add a pinch of red pepper flakes or a dash of sriracha to the dressing.
Roasted sweet potato noodles keep for 4 days in an airtight container, but the dressing will separate slightly after 2 days—just whisk before using. The full salad stays fresh for 3 days if stored properly. For meal prep, portion the dressing separately and toss with noodles before serving. Garnish with toasted sesame seeds right before eating to maintain that fresh, crunchy texture. Freeze the dressing alone for up to 3 months—thaw and whisk before using.
Why You'll Love This Recipe

Step-by-step instructions for sweet potato noodle salad
Transform simple ingredients into a vibrant, roasted sweet potato salad with a rich peanut dressing.
Roast the Sweet Potato Noodles
Preheat your oven to 425°F and line a baking sheet with parchment paper. Spiralize the 2 large sweet potatoes into noodles using a spiralizer or mandoline, then toss them immediately with 1 tablespoon of the extra-virgin olive oil and ½ teaspoon of the sea salt. Spread them in a single layer on the prepared baking sheet, ensuring they don't overlap.
Roast for 20-25 minutes, stirring halfway through, until the noodles are tender and develop a deep golden hue. You'll know they're perfectly roasted when they're fork-tender with caramelized edges. Remove from the oven and let them cool slightly before proceeding—this prevents them from turning mushy when combined with other ingredients.
Prepare the Vegetable Components
While the sweet potatoes roast, thinly slice the 1 medium cucumber into half-moons, the 1 whole red bell pepper into strips, and the ¼ cup red onion into paper-thin slices. Chop the ¼ cup fresh cilantro, removing any tough stems. Transfer all sliced vegetables to a large mixing bowl and set aside.
Toast the 2 tablespoons sesame seeds in a dry skillet over medium heat for 2-3 minutes until fragrant and lightly golden. This adds a nutty depth to the final dish. Let them cool completely before using, as they'll continue to toast slightly when mixed with warm sweet potatoes.
Create the Creamy Peanut Dressing
In a small bowl, whisk together the ½ cup natural peanut butter, ¼ cup lime juice, 2 tablespoons maple syrup, 2 tablespoons soy sauce, ¼ cup extra-virgin olive oil, and 3 minced garlic cloves until completely smooth. The dressing should be thick but pourable—if it's too stiff, add 1-2 teaspoons of water to loosen it.
Season with the remaining ½ teaspoon sea salt and ½ teaspoon black pepper. Taste and adjust the balance of sweetness, acidity, and saltiness—this is where the salad's complex flavor profile comes together. The dressing should coat the back of a spoon with a velvety texture, ready to cling to every strand of sweet potato noodle.
Assemble and Chill the Salad
In a large serving bowl, gently combine the roasted sweet potato noodles with the prepared vegetables. Drizzle the peanut dressing over the top and toss everything together with tongs or clean hands until evenly coated. The noodles should glisten with the creamy dressing while retaining their roasted texture.
Transfer the salad to the refrigerator and let it chill for at least 30 minutes before serving. This allows the flavors to meld and the sweet potatoes to absorb the dressing fully. The salad will keep well for up to 2 days in the fridge, though it's best enjoyed fresh when the sweet potatoes are still warm from the roast.
Garnish and Serve
Before serving, sprinkle the toasted sesame seeds evenly over the salad and give it one final toss to distribute them. The seeds add a satisfying crunch and visual contrast to the creamy, roasted components. Serve immediately over a bed of mixed greens or on its own, accompanied by grilled chicken or tofu for a complete meal.
The ideal serving temperature is slightly chilled but not cold—this ensures the sweet potatoes maintain their texture while the peanut dressing remains creamy. Each bite should deliver a perfect balance of sweet, savory, and tangy flavors with a satisfying bite from the vegetables and seeds.
Pro Tips For Making Sweet Potato Noodle Salad
- SHRED COLD, NOT HOT: Sweet potatoes release starch like a stubborn ex—if you try to shred them warm or straight from the oven, they’ll turn into glue. Let them cool completely first, then spiralize or julienne; they’ll hold their shape and soak up dressing better. (Yes, even if you’re impatient like me.)
- SALT THE PEANUT BUTTER: Natural peanut butter is unsalted by default, and your salad will taste flat if you skip this. Mix in a pinch of flaky salt (½ tsp per 2 tbsp) while emulsifying with lime juice—it balances the sweetness and cuts through the oil. (Trust me, your taste buds will notice.)
- CUT CUCUMBER IN ICE: Toss cucumber slices in a bowl of ice water for 10 minutes before draining. The cold shock tightens the skin, so they stay crisp instead of turning soggy in the dressing. (No, you don’t need a fancy mandoline—just a sharp knife and a bowl of leftover ice cubes.)
- CHAR THE BELL PEPPER: Skip raw bell pepper—it’s bland and watery. Quickly char strips under a broiler (2–3 minutes, watch like a hawk) or in a dry pan until blackened. Peel, cool, and chop; the smoky depth makes the salad taste like it was made by someone who actually cooked. (Your mouth will thank you.)

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can technically substitute regular potatoes, the flavor and texture will be completely different. Sweet potatoes have a natural sweetness and creamier texture when roasted that regular potatoes lack. For the best results, stick with sweet potatoes—they're the star of this dish!
How do I prevent the sweet potato noodles from sticking together?
Toss the noodles immediately with oil and salt after spiralizing, and spread them in a single layer on the baking sheet. Avoid overcrowding—they need space to roast evenly. For extra insurance, lightly oil the parchment paper before arranging the noodles.
Can I make this salad ahead of time?
Roast the sweet potato noodles up to 3 days ahead and store them in an airtight container. Assemble the salad 1 day before serving to let flavors meld. The dressing can be made 5 days ahead—just whisk before using. For best texture, add fresh toppings like sesame seeds right before serving.
What if I don't have a spiralizer?
No problem! Use a mandoline with the thinnest setting or a sharp knife to carefully slice the sweet potatoes into thin strips (about 1/8-inch thick). The texture will be slightly different but still delicious. Just increase roasting time by 5-10 minutes to ensure full tenderness.
How can I make this salad more protein-rich?
Add toasted chickpeas (½ cup), crumbled tofu (½ cup), or edamame (1 cup) for extra protein. For a meat option, stir in grilled chicken or shrimp. The peanut dressing pairs beautifully with all these additions—just adjust the dressing quantity slightly if using wet proteins like shrimp.
