Ingredients for sweet potato noodles recipe vegan
Twelve ingredients transform humble sweet potatoes into restaurant-worthy vegan noodles with caramelized edges and nutty crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Organic preferred, firm texture |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High quality, fruity variety |
| Raw Cashews 🥜 | ½ cup | Unsalted, soaked overnight |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, strained |
| Garlic Cloves 🧄 | 4 cloves | Fresh, minced after roasting |
| Ground Cumin 🌿 | 1 tsp | Toasted for deeper flavor |
| Smoked Paprika 🌶️ | ½ tsp | For subtle smoky depth |
| Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tsp dried thyme |
| Maple Syrup 🍯 | 1 tbsp | Grade B for robust flavor |
| Sesame Seeds 🌰 | 1 tbsp | Toasted for nutty crunch |
| Fresh Cilantro 🌿 | ¼ cup | Chopped for garnish |
| Avocado Oil 🫒 | 1 tbsp | For high-heat roasting |
The sweet potatoes are the star—look for organic varieties with vibrant orange flesh and firm texture. Trader Joe's and Whole Foods carry excellent options, but any fresh sweet potato works. Roasting brings out their natural sweetness, so don't skip this step. For extra flavor depth, I always peel them after roasting—it intensifies the caramelization. The cashews need soaking overnight (or at least 4 hours) to create that creamy, nutty sauce that ties everything together. Raw cashews from bulk bins are the most economical choice.
No cashews? Silken tofu blended with lemon juice mimics the creaminess beautifully. Short on thyme? Fresh rosemary at half the amount adds a piney note that works well. The smoked paprika is non-negotiable for that subtle smokiness—it's what gives these noodles their restaurant-quality depth. For the roasting oil, avocado oil has the highest smoke point, but any neutral oil will do. The sesame seeds should be toasted in a dry pan for 30 seconds until fragrant—this brings out their nutty aroma. And if you're feeling adventurous, swap the maple syrup for agave nectar for a different depth of sweetness.
Roasted sweet potatoes keep in the fridge for 5 days wrapped in foil, but they're best used fresh. The cashew sauce stays fresh for 1 week in an airtight container, and freezes beautifully for 3 months. I always make extra sauce—it's perfect over salads, drizzled on toast, or mixed into dressings. For the noodles themselves, store them in a single layer on a tray before refrigerating to prevent sticking. Reheat gently in a skillet with a splash of water to maintain that perfect texture.
Why You'll Love This Recipe
- I’ll be real: sweet potatoes are one of the most budget-friendly staples out there. Buy a few large ones, store them in a cool, dark place, and you’ve got a pantry hero that lasts weeks. Plus, the cashew sauce stretches easily—double the batch and freeze half for another meal. It’s the kind of recipe that makes me feel smart about grocery shopping and eating well.
- No Spiralizer Needed: I’ll admit, I was skeptical at first—spiralizing sweet potatoes always feels like a chore. But here’s the trick: just slice them into thin, even strips with a knife (or a mandoline if you’re fancy). Toss them in olive oil, roast until tender but still holding shape, and—boom—noodles without the fuss. The edges get this irresistible caramelized crunch that makes up for any wobbly cuts.
- Creamy Without Dairy: That cashew sauce is where this dish becomes ridiculously good. Soak the raw cashews in warm water for 15 minutes, then blend with lemon juice and a splash of water until silky. It’s tangy, rich, and coats those sweet potato strands like a dream—no heavy cream or butter in sight. Honestly, I’ve sent this to non-vegan friends, and they’ve asked for seconds without batting an eye.
- Weeknight to Potluck Star: Between us, this is my go-to when I need something hearty but still light. For weeknights, I’ll toss in sautéed garlic, spinach, and a sprinkle of chili flakes. For potlucks? Add roasted chickpeas and avocado slices—suddenly, it’s a crowd-pleaser that doesn’t scream “vegan.” The best part? It reheats like a champ, so leftovers (which there always are) taste just as good the next day.
Step-by-step instructions for sweet potato noodles
Transform humble sweet potatoes into silky, restaurant-worthy noodles with this vegan technique.
🔥 Step 1: Roast the Sweet Potatoes Until Caramelized
Preheat your oven to 425°F and line a baking sheet with parchment paper. Pierce each of the 2 whole large sweet potatoes with a fork 4-5 times to allow steam to escape. Rub them generously with 1 tablespoon avocado oil—this high-smoke-point oil handles the heat beautifully without burning.
Place the sweet potatoes directly on the baking sheet (no need for a rack) and roast for 45-50 minutes, turning them halfway through, until their skins are deeply caramelized and a knife slides in with minimal resistance. The edges should be slightly charred—this adds incredible depth of flavor. Let them cool completely before handling; they'll be extremely hot and the skins will be delicate.
👨🍳 Step 2: Create the Nutty Crunch Base
While the sweet potatoes roast, toast the 1 tablespoon sesame seeds in a dry skillet over medium heat for 2-3 minutes until golden and fragrant. Immediately transfer to a plate to cool. In the same skillet, add 1 tablespoon avocado oil and toast the 4 cloves garlic cloves (peeled) for 1 minute until just golden—don't let them brown or they'll turn bitter.
Transfer the garlic to a food processor along with the 0.5 cup soaked raw cashews, 1 teaspoon ground cumin, 0.5 teaspoon smoked paprika, and 1.5 teaspoons sea salt. Pulse until combined but still slightly textured—you want a coarse, nutty paste that will coat the noodles beautifully. With the processor running, slowly drizzle in the 0.25 cup extra-virgin olive oil and 1 tablespoon maple syrup until fully incorporated.
🔪 Step 3: Spiralize and Toss the Noodles
Using a vegetable peeler or mandoline with a julienne attachment, carefully peel the cooled sweet potatoes into long, thin noodles. The skin should come off easily now that they're roasted—discard any tough patches. Immediately toss the noodles with the cashew-garlic paste in a large bowl, massaging gently to ensure even coating. This step is crucial for flavor distribution and preventing the noodles from sticking together.
Add the 2 tablespoons lemon juice and 0.25 cup fresh thyme leaves (finely chopped if needed) to the bowl. Toss everything together until the noodles are uniformly coated and the thyme is evenly distributed. Let them marinate at room temperature for 10 minutes—this allows the flavors to meld and the noodles to soften slightly.
🥘 Step 4: Finish with Fresh Herbs and Garnish
Gently reheat the noodles in a large skillet over medium-low heat for 2-3 minutes, stirring occasionally, until warmed through but not mushy. The residual heat from the roasting will carry them through. Remove from heat and immediately stir in the 0.25 cup fresh cilantro and the toasted sesame seeds.
Taste and adjust seasoning—you might need a pinch more salt or a squeeze of lemon to balance the sweetness. Serve immediately while still warm, garnished with additional sesame seeds and cilantro if desired. These noodles are best enjoyed fresh, with their silky texture and perfect balance of sweet, nutty, and herby flavors.
Pro Tips For Making Sweet Potato Noodles Recipe Vegan
- Peel When Cool: Sweet potatoes stay glued to the peeler when hot—wait until they’ve cooled for 10 minutes first. I learned this the hard way after peeling a batch that kept sticking and turning into a mushy mess. A damp towel helps too if you’re impatient.
- Soak Cashews 15 Minutes: Toss raw cashews in warm water for at least 15 minutes before blending—they’ll crush smoother and the sauce won’t taste chalky. I used to skip this and ended up with a gritty, unsatisfying texture every time.
- Spiralize Dry, Not Damp: Pat sweet potatoes completely dry before running them through the spiralizer—wet noodles stick together and clog the blade instantly. Use a paper towel to wipe them down if needed; it’s a small effort that saves frustration.
- Roast Noodles First: Toss spiralized sweet potatoes in olive oil and roast at 400°F (200°C) for 10–12 minutes before cooking. This step caramelizes the edges and adds depth—no one ever regrets doing it, but everyone skips it until they try it.
Make-ahead tips for this dish
Prep Ahead Sauce
Make the cashew-garlic sauce up to 3 days ahead—it actually tastes better as the flavors meld! Store it in an airtight container in the fridge, and give it a quick stir before using.
For extra richness, add 1 tablespoon nutritional yeast when blending. I like to make a double batch because this sauce is perfect over grain bowls or drizzled on toast. 💫
Roast in Advance
Roast the sweet potatoes the night before and store them in the fridge for up to 5 days. This is a total game-changer for busy weeknights. Just reheat the roasted potatoes in a 350°F oven for 10 minutes before spiralizing—this keeps them perfectly tender.
I always do this when I'm prepping for meal prep Sundays.
Freezer-Friendly Noodles
For a true time-saver, spiralize the sweet potatoes and toss them with 1 tablespoon olive oil and a pinch of salt. Spread them in a single layer on a tray, freeze until solid, then transfer to a freezer bag for up to 2 months.
When ready to cook, simply thaw, toss with your pre-made sauce, and warm through in a skillet. The texture holds up beautifully! ❄️
Sauce Variations
Want to switch up the flavor? Swap the cashew sauce for a peanut sauce by blending 0.5 cup peanut butter, 2 tablespoons soy sauce, 1 tablespoon lime juice, and 1 tablespoon maple syrup.
Or go for a creamy tahini dressing with 0.25 cup tahini, 2 tablespoons lemon juice, and 1 tablespoon water. Both keep well in the fridge for 5 days.
Portioning for Meals
Divide the fully assembled noodles into 4 meal-prep containers with a tight-fitting lid. Store in the fridge for 3 days or freeze for 2 months. When reheating, microwave for 1-2 minutes with a splash of water to prevent drying.
I love packing these in bento boxes with roasted chickpeas and avocado slices for a complete meal on the go.
Garnish Fresh
Keep your fresh herbs and sesame seeds separate until serving. Toast the sesame seeds again before garnishing to restore their nutty aroma. Fresh cilantro or parsley adds a bright pop of color—just chop them right before serving.
This keeps your dish looking vibrant and tasting fresh, even when using prepped ingredients. 🌿

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes won't work well for this recipe—they lack the natural sweetness and rich texture that makes sweet potato noodles special. The caramelization process relies on sweet potatoes' natural sugars, which develop that signature nutty depth. For a similar texture, try butternut squash noodles instead.
How do I prevent the noodles from sticking together?
Toss the freshly spiralized noodles immediately with the cashew-garlic paste and a light coating of oil. The key is to work quickly and massage them gently in the bowl. If they start sticking, add 1 teaspoon more oil and toss again. Spreading them on a tray before freezing also helps prevent clumping.
What's the best way to reheat these noodles?
Reheat gently in a skillet over medium-low heat for 2-3 minutes with a splash of water to maintain their silky texture. Microwaving works too, but add 1 teaspoon water and cover with a damp paper towel to prevent drying. Never reheat in the oven—it will make them rubbery.
Can I make this gluten-free?
This recipe is already naturally gluten-free! All ingredients are plant-based and free from wheat or gluten-containing additives. The only potential cross-contamination risk would be if you use a shared spiralizer or cutting board that hasn't been cleaned between uses.
What if I don't have a spiralizer?
No problem! Use a sharp vegetable peeler or mandoline with a julienne attachment for similar results. For extra-thin noodles, slice the roasted sweet potato lengthwise into 1/8-inch thick strips. Just be sure to work quickly to prevent browning while you prepare them.
