How to Use the Cooking Oil Smoke Point Guide
Select your cooking method to instantly see the best oils for that application, their smoke points, and which oils to avoid. Covers 9 cooking methods from high-heat frying to cold salad dressings.
The smoke point is the temperature at which oil starts to smoke and release harmful compounds. Cooking above an oil's smoke point creates aldehydes and acrolein, ruins flavor, and destroys nutrients like antioxidants and vitamin E.
Refined oils generally have higher smoke points than unrefined (virgin) versions because the refining process removes impurities. The tradeoff is less flavor and fewer nutrients — so unrefined oils are best for low-heat cooking and finishing.
Frequently Asked Questions
You can reuse frying oil 2–3 times if it hasn't been overheated and you filter out food particles. Discard it if it smells rancid, turns dark, or produces excessive foam. Each use lowers the effective smoke point slightly.
Butter contains milk solids (proteins and lactose) that burn at around 300–350°F. To get the butter flavor at higher heat, use clarified butter (ghee), which removes the milk solids and raises the smoke point to 450–485°F.
Refined coconut oil (450°F smoke point) is stable at high heat and works well for frying. It's high in saturated fat, but primarily medium-chain triglycerides (MCTs). For general health, variety is best — rotate oils for a balanced fatty acid profile.
