The kitchen brigade system establishes a hierarchy of roles and responsibilities in a professional kitchen. At the top is the executive chef who oversees all kitchen operations including quality control, menu planning, and staff management. Below the executive chef are sous chefs who assist in daily operations and handle guest issues. Other key roles include pastry chefs, bakers, butchers, and chefs de partie who focus on specific dishes or stations. The chief steward oversees cleaning and ensures health standards are met.
