The primary metric to consider is the smoke point, which is the temperature at which an oil breaks down and begins to smoke. The goal is often to achieve a contrast between a crisp, golden exterior and a tender, juicy interior.
Understanding Smoke Points for Cooking Oils
A thin film of oil conducts heat to the surface of the food, rapidly dehydrating it and creating a crisp exterior through dehydration and polymerization. Using an oil with a low smoke point for high-heat cooking results in acrid smoke, burnt flavors, and the creation of harmful free radicals.
This rapid and even heating is what enables the Maillard reaction, a complex chemical process where amino acids and reducing sugars react at high temperatures. This reaction is responsible for the development of deep, savory umami flavors and the appealing golden-brown crust that defines a perfectly seared steak or crispy piece of fried chicken.

This is why French fries achieve their satisfying crunch and why a breaded cutlet maintains its shattering crispness. For high-temperature applications like deep frying or stir-frying, refined oils such as avocado, peanut, or grapeseed oil are ideal due to their high smoke points.
