In cooking, to season means to add salt and other flavouring ingredients to food to improve or balance its natural flavour. Seasoning may include salt, pepper, herbs, spices, citrus, vinegar, aromatics and other ingredients chosen for the dish. The term also has a second culinary meaning: to season cookware by applying a thin layer of oil and heating it to develop a protective, relatively non-stick surface, especially on cast iron and carbon steel.
Salt is the most common seasoning because it enhances flavour and changes how other tastes are perceived. Acid can brighten a dish, herbs and spices add aroma, and heat can contribute pungency. Seasoning should support the principal ingredient rather than mask it.
Chefs often season in stages as a dish is prepared. Salt added early has time to dissolve and distribute, while final seasoning adjusts the finished balance. The timing depends on the ingredient and method: meat may be salted before cooking, vegetables can be seasoned during sautéing, and a sauce is usually tasted and adjusted before service. Take care with reductions, cured products, salted stocks and other ingredients that may concentrate salt.
Example: season a soup lightly during cooking, reduce it to the required consistency, then taste and adjust salt, acidity and aromatics before service.
Seasoning cast iron or carbon steel means applying a very thin layer of suitable oil and heating the pan so the oil forms a bonded protective layer. This helps reduce rust and improves release over time. It is different from adding flavouring to food. Follow the cookware manufacturer’s instructions for the oil, temperature and maintenance routine.
Chef’s tip: Taste at more than one stage, use a clean tasting spoon and account for ingredients that add hidden salt. A dish can be well-seasoned without tasting overtly salty.
Key distinction: Seasoning food means adjusting flavour; seasoning a pan means building and maintaining its protective oil layer.
