Transform leftover pasta into a bold, Sichuan-inspired late night meal.

Late Night Hot and Sour Noodles · 3:34 · Video: J. Kenji López-Alt · Watch at the source

In short: This guide demonstrates how to create a flavorful noodle dish using pantry staples and leftover pasta. It is a practical approach to late-night cooking that relies on balancing acidity, heat, and savory depth without extensive preparation.

The dish centers on a sauce profile defined by the interplay of light soy sauce, black vinegar—specifically Chinkiang—and a combination of roasted chile oil and Sichuan pepper oil. For convenience, these oils can be replaced by a single store-bought spicy chile crisp.

To round out the flavor, the recipe incorporates sugar and MSG, topped with fresh scallions and cilantro. While traditional noodles are standard, the method is versatile enough to utilize leftover Italian-style pasta, making it an accessible solution for quick, minimal-prep meals.
