Sweet Potato Noodles Recipe

Prepare sweet potatoes

Wash and scrub the purple sweet potatoes. Trim ends and cut into chunks that will fit into a blender or food processor (roughly 1–2 inch pieces). No need to peel unless you prefer a smoother color; skins are edible and nutritious.

Steam the sweet potato chunks until very tender, about 12–15 minutes depending on size. They should pierce easily with a fork.

Place the steamed sweet potato chunks into a high-speed blender or food processor. Add 60–100 ml of the water and 1/2 tsp salt. Blend until very smooth, scraping down sides. The mixture should be thick but pourable; add more water 1 tablespoon at a time if needed (up to the 500 ml total indicated) to reach a ribbon‑like batter.

If you want a noodle with more structure (closer to shirataki texture), thin the purée slightly and use a spiralizer attachment (or piping bag with a large round tip) to extrude into cold water to set briefly; otherwise proceed to make quick pan noodles below.

To make quick pan-style noodles: heat a nonstick skillet over medium-low with a light spray of oil (or use a well-seasoned pan without oil for lower calories). Spoon or pour thin ribbons of the purée into the pan, spreading to about 1/4-inch thick ribbons (use a small offset spatula or spoon). Cook 2–3 minutes until edges set and bottom develops slight color, then gently flip pieces and cook another 1–2 minutes. For longer noodle strands, pipe long ribbons and cook similarly. Remove to a tray and let cool slightly; the set purée will have a noodle-like chew. This yields a low-calorie, gluten‑free, vegan noodle base.

While noodles cook, whisk together 2 tbs tamari, 1 tbs rice vinegar, 1 tsp toasted sesame oil, grated ginger, minced garlic, red pepper flakes, maple syrup (if using), and 1 tbs fresh lime juice in a small bowl until combined. Taste and adjust: add a pinch more sugar or maple if too sharp, or extra tamari for saltiness.

If using tofu or edamame, lightly pan-fry the pressed tofu in a nonstick skillet over medium heat until edges are golden (about 3–4 minutes per side) using 1 tsp oil, then toss with a tablespoon of the sauce to coat. Alternatively, warm edamame briefly in the skillet and toss with sauce.

Place the cooked sweet potato noodles in a large bowl or individual serving plates. Pour the prepared sauce over the noodles and gently toss to coat. If the noodles are sticky, add the sauce gradually and use a folding motion to avoid breaking them.

Add sliced scallions, julienned carrot, chopped cilantro, toasted sesame seeds, and crushed peanuts (if using). Toss lightly to distribute garnish. Taste and adjust with extra lime juice, tamari, or a pinch of salt to preference.

Serve immediately warm or at room temperature. Leftover noodles keep covered in the refrigerator for up to 2 days; reheat gently in a skillet or enjoy cold as a salad. If stored separately, keep sauce in a small container to preserve texture.
