Cooking Oil Smoke Point Guide
Look up smoke points in °F and °C for 13 cooking oils including olive, avocado, coconut, and canola.
Matches each oil to frying, sauteing, and baking uses.
The smoke point is the temperature at which a cooking oil begins to break down and produce visible smoke. Heating oil beyond its smoke point creates harmful compounds and unpleasant flavors.
Why smoke points matter:
- Above the smoke point, oils release acrolein and other toxic compounds.
- The flavor degrades, giving food a burnt or bitter taste.
- The nutritional value of the oil decreases.
- It can set off smoke alarms and create a fire hazard.
Smoke points of common cooking oils:
| Oil | Smoke Point | Best For |
|---|---|---|
| Avocado oil (refined) | 518°F / 270°C | Deep frying, high-heat searing |
| Rice bran oil | 490°F / 254°C | Stir-frying, deep frying |
| Light olive oil (refined) | 465°F / 240°C | Frying, roasting |
| Peanut oil (refined) | 450°F / 232°C | Deep frying, Asian cooking |
| Coconut oil (refined) | 450°F / 232°C | Frying, baking, medium-heat sauteing |
| Sunflower oil (refined) | 440°F / 227°C | Frying, baking |
| Canola oil | 400°F / 204°C | General cooking, deep frying, baking |
| Extra virgin olive oil | 374°F / 190°C | Low-heat sauteing, dressings |
| Butter | 350°F / 177°C | Light sauteing, baking |
| Coconut oil (unrefined) | 350°F / 177°C | Low-heat cooking, baking |
| Toasted sesame oil | 350°F / 177°C | Finishing, dressings |
| Walnut oil | 320°F / 160°C | Dressings, finishing |
| Flaxseed oil | 225°F / 107°C | Dressings only, never heat |
These match the figures used by the deep fry temperature and cooking oil amount calculators. Treat all of them as approximate: refining matters more than the plant does, smoke point falls as an oil ages, and it falls fast once the oil has been through a few frying sessions.
Cooking method temperatures:
- Deep frying: 350-375°F (177-190°C)
- Stir-frying and searing: 400-450°F (204-232°C)
- Sauteing: 320-375°F (160-190°C)
- Baking: 325-425°F (163-218°C)
- Salad dressings: no heat
Why baking is the exception
For frying, sautéing and searing, the oil sits in the pan taking the full heat, so its smoke point is the constraint and the rule is simple: pick an oil whose smoke point clears the pan temperature with room to spare.
Baking does not work that way. The oil is dispersed through a batter or coating a vegetable, surrounded by water that cannot exceed 100°C until it has boiled off. Butter smokes at 350°F and is baked at 400°F constantly without incident, because the butter in a cake never reaches oven temperature. So this calculator applies the smoke-point test to the direct-heat methods and tells you what actually matters for baking, which is flavor.
