Szechuan beef is a Chinese dish that originated in the Sichuan province and is known for its spicy and bold flavors. It is a stir-fry dish that typically consists of thinly sliced beef that is marinated in a mixture of soy sauce, garlic, crushed red pepper, and cornstarch. The beef is then fried alongside other ingredients such as broccoli, water chestnuts, onions, and peppers. The dish is known for its rich flavor and spiciness, which comes from the use of Szechuan peppercorns and dried red chilies. The sauce used in Szechuan beef is typically a combination of soy sauce, hoisin sauce, sesame oil, and beef broth. Szechuan beef is often served with rice or noodles and pairs well with other Chinese dishes such as potstickers, wontons, and lettuce wraps.
