Baking vs. Roasting: What is the Difference and Why Does it Matter?

Many people use the terms baking and roasting interchangeably, and in a domestic oven they look the same from the outside. But the distinction is meaningful and understanding it will help you cook more intuitively.

Roasting is applied to ingredients that have inherent structural integrity -- meats, fish, and dense vegetables. The goal is to create surface browning (via the Maillard reaction) while cooking the interior to the correct doneness. Roasting temperatures tend to be higher, typically 180-230C, and the fat on the surface of the ingredient is a key part of the cooking process. Basting, resting, and achieving the right internal temperature are the primary concerns.

Baking, on the other hand, is about transformation. Bread dough bakes into bread. Cake batter bakes into cake. The heat is doing chemical work -- denaturing proteins, gelatinizing starches, setting structures -- that creates something fundamentally different from what went in. The temperature matters enormously because the window between "not set" and "overbaked" can be narrow. This is why baking is often called a science: precision matters far more than it does in roasting. The practical consequence is that when baking, you should always use your oven thermometer rather than trusting the dial, always measure by weight rather than volume, and always resist opening the oven door during the first two-thirds of the baking time.
