• 4 scallions, whites and greens separated, thinly sliced
• 1/2 cup vegetable oil
• 1 tablespoon crushed red pepper flakes
• 2 teaspoons sesame seeds
• 2 teaspoons Sichuan pepper, coarsely chopped

Kosher salt

• 3 tablespoons reduced-sodium soy sauce
• 2 teaspoons toasted sesame oil
• 1 teaspoon sugar

1. Cook scallion whites, vegetable oil, red pepper flakes, sesame seeds, and pepper in a small saucepan over low heat, stirring occasionally, until oil is sizzling and scallions are golden brown, 12–15 minutes; let chili oil cool in saucepan.
2. Meanwhile, cook noodles in a large pot of salted boiling water until al dente; drain. Rinse under cold water and drain well.
