What cooking method is primarily used by Panda Express for their entrees?

Panda Express primarily employs wok cooking as their main cooking method for entrees. This method is deeply rooted in Chinese culinary traditions and is characterized by its high heat and quick cooking time, allowing for vibrant flavors and the retention of nutrients in vegetables and proteins. Wok cooking enables chefs to achieve a unique texture and taste by quickly stir-frying ingredients in a small amount of oil.

This technique often involves tossing ingredients rapidly in the wok, which promotes even cooking and can create a desirable char or sear, enhancing the overall flavor profile of the dishes. This contrasts with other methods such as frying, grilling, or steaming, each of which has its distinct qualities and impacts on the final dish.

Frying, although used in the preparation of some menu items, typically incorporates more oil and focuses on different textures, while grilling is less common in Chinese cuisine and emphasizes a different cooking technique. Steaming, while a healthier option, does not provide the same depth of flavor or appealing texture that wok cooking achieves. Therefore, wok cooking is integral to the signature dishes found at Panda Express, making it the correct answer.
