Sweet Potato Vermicelli Noodles Recipe: Silky Rice Noodles Wrapped in Sweet Potato Creaminess

This sweet potato vermicelli noodles recipe transforms humble rice noodles into a silky, golden-hued dish with natural sweetness and earthy depth. 🌟 The secret lies in blending steamed sweet potatoes into the broth, creating a velvety sauce that clings to every strand while keeping the noodles perfectly tender.

I developed this after craving something hearty yet light—ideal for both hot bowls and chilled salads. What sets this apart is the versatility—it works as a comforting soup with coconut milk or as a refreshing salad with lime and herbs.

The sweet potato adds natural sweetness without sugar, while the broth (peanut, chili-lime, or ginger-turmeric) lets you customize the flavor profile. No animal products are needed, making it equally satisfying for plant-based eaters.

The result is a dish that’s naturally vibrant, with strands of noodles coated in a glossy, sweet potato-infused sauce. Each bite delivers a balance of textures—chewy noodles, creamy sweet potato, and a hint of spice or tang.

It’s the kind of meal that feels indulgent yet light, perfect for weeknight dinners or meal prep. Whether you’re serving it warm with fresh herbs or chilled with a zesty dressing, this recipe proves that sweet potatoes can elevate simple rice noodles into something extraordinary. Let’s get cooking!

Ingredients for sweet potato vermicelli noodles

Sweet potatoes, silky noodles, and creamy coconut milk—this combo transforms simple ingredients into something extraordinary.

The sweet potatoes are the star here. Orange-fleshed varieties like Jewel or Garnet give the best natural sweetness. I grab mine from the organic section at Whole Foods or Trader Joe's—they're usually pre-washed and ready to go. If you're using regular sweet potatoes, they'll work too, but the flavor isn't quite as vibrant. For this recipe, we're steaming them whole first, then blending them into a velvety puree that becomes the base of our sauce. Pro tip: don't peel them until after steaming—the skins stay on during cooking to keep them from turning mushy.

No coconut milk? Cashew cream (blend soaked cashews with water) works perfectly, though it'll be slightly thinner. Fresh cilantro is ideal, but dried won't ruin it—just use one-third the amount. Thai basil adds that signature Southeast Asian flavor, but regular basil or mint can stand in if you're improvising. The peanut butter and tahini are what give this dish that rich, nutty depth—skip the tahini if you're avoiding sesame (though it's totally worth it). For the chili peppers, I like to use Thai bird's eye peppers if I can find them, but regular serranos or jalapeños work too. Always remove the seeds if you want less heat.

This dish keeps beautifully—3-4 days in the fridge, covered with a damp paper towel to prevent drying. For longer storage, freeze the sauce separately from the noodles (they don't like freezing well). Reheat gently on low—microwaving can make the noodles gummy. I love making a big batch on Sundays and using it for lunches all week. The sauce thickens as it cools, so if it seems too thick when reheating, just add a splash of warm water or broth. And if you're prepping for a crowd, double the sauce recipe—the noodles can be cooked fresh when serving.

Step-by-step instructions for sweet potato vermicelli noodles

Here's how to make these dreamy noodles—creamy, spicy, and packed with flavor.

Preheat your oven to 400°F. Toss the peeled and cubed 2 whole Large Sweet Potatoes with 1 tablespoon sesame oil, ½ teaspoon sea salt, and ¼ teaspoon black pepper. Spread them on a baking sheet in a single layer—they need room to crisp slightly.

Roast for 25-30 minutes until fork-tender with slightly crisp edges. You'll know they're done when the outside is golden and the inside gives way easily. Let them cool slightly before transferring to a blender—this makes peeling the skins off effortless later.

Once cooled, peel the skins off the roasted sweet potatoes (they'll come right off). Transfer the flesh to a blender with 1 can coconut milk (reserve ¼ cup for garnish), 2 tablespoons peanut butter, 1 tablespoon tahini, and 1 tablespoon maple syrup.

Blend until completely smooth, scraping down the sides as needed. The mixture should be velvety with no lumps. Taste and adjust seasoning—add more sea salt or maple syrup if needed. This creamy base is the heart of your noodles, so don't rush it.

While the sweet potato mixture cooks, prepare the 8 oz vermicelli rice noodles. Soak dried noodles in hot water for 10-15 minutes (or follow package instructions for fresh noodles) until pliable but still holding shape. Drain and rinse briefly under cold water to stop cooking.

Heat 1 tablespoon sesame oil in a large wok or skillet over medium-high heat. Add 4 minced garlic cloves and 2 thinly sliced red chili peppers (seeds removed). Stir-fry for 1-2 minutes until fragrant but not burned—just enough to wake up those flavors.

Pour the sweet potato cream base into the skillet with the garlic and chili. Add 2 cups vegetable broth and bring to a gentle simmer. Toss in the drained noodles, stirring until everything is well-coated and heated through (3-4 minutes). The sauce should cling beautifully to the noodles.

Remove from heat and stir in ½ cup lime juice, ¼ cup chopped fresh cilantro, and ⅛ cup chopped fresh Thai basil. Give it one final taste—balance the flavors with more lime or salt if needed. The noodles should be tender, the sauce silky, and the heat from the chili peppers just right.

Divide the noodles among bowls. Drizzle with the reserved ¼ cup coconut milk and top with extra chopped cilantro, Thai basil, and a sprinkle of black pepper. For an extra touch, add a few slices of fresh chili pepper on top.

Serve immediately while warm—these noodles are best enjoyed fresh. The sweet potato cream should coat every strand, the coconut milk adds richness, and the lime brightens everything up. Pair with a simple cucumber salad to cut through the richness if you like!

Wine and beer pairings for these flavors

Creamy Coconut Whites

For this sweet potato vermicelli dish, I love pairing it with a dry Riesling from Germany or Austria—look for one with crisp acidity and subtle honeyed notes. The Mosel region produces excellent examples like Dr. Loosen "Blue Slate" Riesling, where the mineral finish cuts through the coconut richness beautifully.

The slight sweetness in the wine mirrors the natural sweetness of the roasted sweet potatoes, while the acidity keeps your palate fresh between bites. 🍷

Spicy Thai Reds

If you prefer red wine, opt for a light-bodied Thai red like Meokaw Thai Red Blend or a Pinot Noir from California’s Russian River Valley.

These wines have enough fruit to complement the peanut butter and tahini in the sauce, while their earthy undertones enhance the sweet potato’s natural depth. The Pinot Noir’s bright acidity also stands up to the lime juice, creating a harmonious balance.

For a bolder option, try a Gewürztraminer—its lychee and floral notes add an unexpected but delicious twist.

Craft Beer Pairings

For beer lovers, a crisp pale ale with citrus notes works wonders. I recommend Allagash White or Sierra Nevada Pale Ale—both have enough hop bitterness to contrast the dish’s creaminess while their citrusy finish echoes the lime juice.

If you want something darker, try a lightly spiced wheat beer like Blue Moon or a Belgian witbier such as Hoegaarden. The banana and spice notes in witbiers complement the sweet potato’s natural caramelization, while the effervescence cleanses your palate between bites. 🍺

Non-Alcoholic Options

Skip the alcohol? No problem! A sparkling yuzu soda (like San Pellegrino Aranciata) adds a refreshing citrus kick that mirrors the lime in the dish. For something warmer, try hibiscus iced tea—its tart, cranberry-like flavor balances the sweetness of the noodles.

If you prefer a creamy option, a coconut milk-based horchata (made with rice milk and cinnamon) enhances the dish’s tropical vibe while keeping it vegan-friendly. 🥤

Regional Wine Adaptations

In Southeast Asia, where sweet potato noodles are popular, locals often pair them with rice wine like Lao Lao or Thai rice wine (Sao). For a Western twist, a Champagne or Prosecco adds a celebratory touch—its bubbles and acidity make the dish feel extra special.

If you’re in Japan, try pairing with a dry sake like Dassai—its clean, crisp profile highlights the dish’s delicate flavors without overpowering them. Each region brings its own unique twist to the pairing game! 🌏
