Let's get started with this game-changing preparation method.

Ingredients for spiralized sweet potato noodles

Perfectly roasted garlic and vibrant herbs transform simple sweet potatoes into restaurant-quality noodles.

The sweet potatoes are the foundation—organic, firm varieties like Jewel or Beauregard hold their shape best. Whole Foods or local farmers markets often carry the best quality, but any well-stocked grocery store will have them. Look for potatoes that are heavy for their size and have smooth, unblemished skin. The garlic should be fresh, plump cloves with no sprouting—Costco or Trader Joe's sell great bulk options. Fresh herbs make all the difference here: Whole Foods or local herb vendors have the freshest parsley, thyme, and rosemary, but even grocery store selections work if they're vibrant and free from wilting.

No fresh herbs? Dried thyme at one-third the amount works in a pinch, though fresh delivers that bright, aromatic punch. Running low on vegetable broth? Water plus a bouillon cube gives similar flavor. The nutritional yeast adds that savory depth—Bob's Red Mill brand is widely available and consistently high quality. For the roasted garlic, don't skip the peeling step—it's easier than you think if you smash the cloves first. Olive oil matters here too: use something fruity and peppery like California Extra Virgin or Colavita for the best flavor infusion. The avocado oil for sautéing should have a high smoke point—Primal Kitchen or Chosen Foods brands are excellent choices.

Spiralized sweet potatoes oxidize quickly, so toss them immediately with lemon juice after cutting to preserve color and freshness. Store any leftovers in an airtight container with a damp paper towel to maintain moisture—keeps for 3-4 days in the fridge. The roasted garlic can be prepped ahead and stored in the freezer for up to 3 months, making it a perfect flavor booster for other dishes. These noodles reheat beautifully—just warm gently in a pan with a splash of water to prevent drying. For meal prep, portion into containers with a light drizzle of olive oil to maintain crispness.

Step-by-step instructions for roasted garlic sweet potato noodles

Transform simple sweet potatoes into restaurant-worthy noodles with this precise roasting and herb technique.

Preheat your oven to 425°F and line two baking sheets with parchment paper. Cut the 2 whole large sweet potatoes lengthwise into ½-inch thick planks, then slice each plank into ¼-inch thick rounds using a mandoline or sharp knife. Arrange the sweet potato rounds in a single layer on one baking sheet, brushing each with 1 tablespoon of the extra-virgin olive oil.

In a small bowl, toss the 6 whole peeled garlic cloves with 1 tablespoon of the remaining extra-virgin olive oil, ½ teaspoon of the sea salt, and ¼ teaspoon of the ground black pepper. Spread them on the second baking sheet. Roast both sheets for 20-25 minutes until the sweet potatoes are tender when pierced with a knife and the garlic cloves are golden and caramelized.

Remove the sweet potatoes from the oven and let them cool slightly. Using a spiralizer, carefully transform each cooled sweet potato round into noodles, working quickly to prevent them from sticking. As you spiralize, immediately transfer the noodles to a large bowl and toss with 1 tablespoon avocado oil, ½ teaspoon sea salt, and ¼ teaspoon ground black pepper.

Heat a large skillet over medium-high heat and add the sweet potato noodles in batches. Sauté for 3-4 minutes until they begin to soften slightly but remain slightly firm to the bite. Remove from heat and set aside, keeping warm.

In the same skillet, add the roasted garlic cloves and cook for 1 minute until fragrant. Remove the garlic and set aside. To the skillet, add 2 tablespoons fresh thyme leaves, 1 tablespoon fresh rosemary, and 2 tablespoons lemon juice. Cook for 30 seconds, stirring constantly, until the herbs release their aromas.

Pour in the ¼ cup vegetable broth and scrape up any browned bits from the bottom of the pan. Bring to a gentle simmer and let it reduce by half, about 3-4 minutes. Stir in the 2 tablespoons nutritional yeast and the reserved roasted garlic cloves, mashing them slightly to release their flavor.

Return the sweet potato noodles to the skillet and toss gently to coat them evenly in the herb garlic broth. Cook for an additional 2-3 minutes until everything is heated through and the noodles have absorbed the flavors. Transfer to a serving platter and garnish with the ¼ cup fresh parsley, chopped finely.

Serve immediately while the noodles are still warm and slightly crisp at the edges. The roasted garlic and herbs should infuse every bite with rich, umami depth, while the lemon juice brightens the naturally sweet potatoes. This dish pairs beautifully with a simple arugula salad or grilled protein for a complete meal.
