Maillard Reaction/my-yar/
The browning chemistry between amino acids and sugars at 300°F+. Responsible for the crust on seared steak, bread, coffee, and roast vegetables.
View on brothh.comWhat it means
The Maillard reaction is a chemical cascade that starts around 300°F (150°C) when proteins and sugars rearrange into hundreds of new flavor and aroma compounds. It is NOT caramelization (which is sugar alone) — Maillard requires both amino acids and reducing sugars.
The reaction drives the brown crust on seared meat, the color and aroma of coffee roasting, the flavor of toasted bread, and most "savory roasted" flavors. Hotter and drier conditions produce faster Maillard; water on the surface suppresses it because water evaporation keeps the surface at 212°F.
Examples
Dry a steak first
Pat dry before searing — water = no Maillard until it evaporates.
Deglaze after
The brown stuff stuck to the pan (fond) is pure Maillard; deglaze with stock or wine to capture it.
Do
- Work hot and dry — 400°F+ pan or oven, patted-dry surface.
Don't
- Crowd a sauté pan — food releases moisture, temperature drops, food steams instead of browns.
History
Named for French chemist Louis-Camille Maillard who first described the reaction in 1912 while studying how amino acids and sugars interact. The full mechanism is still actively researched — there are hundreds of reactions that fall under the "Maillard" umbrella.
