Grill vs. Roast: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 9, 2023
Grilling involves cooking food on an open flame or heat source, often quickly; roasting is slower, using indirect, dry heat, often in an oven.

Key Differences

Grilling is a method where food is cooked directly over a heat source, typically using high temperatures, which imparts a unique charred flavor. Roasting, on the other hand, involves cooking food, usually in an oven, using indirect heat at lower temperatures for a longer duration, allowing flavors to develop more deeply.
Grills are often open structures with a heat source below, such as charcoal or gas burners, suitable for outdoor cooking. Roasting is typically done in an oven, a closed environment where heat circulates around the food, making it a common indoor cooking method.
Common foods for grilling include steaks, burgers, and vegetables, which benefit from the high heat and smoky flavor. Roast dishes often include meats like chicken, beef, or vegetables, which are cooked more slowly, retaining moisture and developing complex flavors.
Grilling is usually a quick process, taking minutes for thin cuts of meat or vegetables. Roasting is a slower process, often taking hours, as it gently cooks the food through radiant heat, making it ideal for tenderizing tougher cuts of meat.
Grilling imparts a distinct charred and smoky flavor due to the high heat and direct flame contact. Roasting allows for a more subtle flavor development, as herbs and spices can infuse the food over the extended cooking time.
