Convection vs. Grill — What's the Difference?

By Tayyaba Rehman — Updated on September 20, 2023
Convection is a method of cooking that circulates hot air around food to cook it evenly. Grill refers to cooking food on a grill, usually over an open flame, to achieve a charred texture.

Difference Between Convection and Grill

Key Differences

Convection and Grill are both cooking methods but achieve different results. Convection involves the circulation of hot air around the food, often with the use of a fan in ovens. This method provides an even and efficient cooking process. Grill, on the other hand, refers to cooking food on a grill grate, often over an open flame, which produces a different texture, usually a sear or char on the surface.
In terms of cooking equipment, Convection ovens are specially designed to circulate air, while grills are open structures often fueled by charcoal, gas, or electricity. When using Convection, the food typically doesn't have to be flipped, thanks to the even distribution of heat. Grilling, however, usually requires the food to be flipped for even cooking and to achieve grill marks.
When discussing Convection and Grill, it's important to mention the type of foods that are best suited for each method. Convection is great for baked goods, roasts, and dishes that benefit from even cooking. Grill is often the go-to for meats, vegetables, and foods that are enhanced by a smoky flavor and crisp exterior.
From a health perspective, Convection cooking usually involves less fat since it doesn't require additional oils to conduct heat. Grill cooking can be healthier if the fats from the food can drip away, but the charred portions might contain harmful compounds. Both methods have their merits and drawbacks, depending on what you are aiming to cook.
