Wheat noodles are tossed in an intensely numbing mala sauce with Sichuan peppercorn and chili. This bold dish is a quick family meal that pairs perfectly with added protein like chicken or beef.
Cook the dried wheat noodles according to package instructions until just al dente; drain thoroughly and toss with 1 tsp sesame oil to prevent sticking.
Toast the Sichuan peppercorns in a dry skillet over medium-low heat for 2 minutes until fragrant; finely crush with a mortar and pestle.
In a large mixing bowl, combine the chili oil, light soy sauce, dark soy sauce, black vinegar, sugar, minced garlic, the crushed Sichuan peppercorns, and remaining sesame oil.
Add the drained noodles to the bowl and toss vigorously until evenly coated with the mala sauce. Let them sit for 2–3 minutes to allow flavors to develop.
Garnish with thinly sliced green onions, chopped cilantro, and crushed peanuts just before serving. Serve immediately for the best spicy, numbing texture.
