Cooking Oil Smoke Points Cheat Sheet for High-Heat Cooking

Choosing the wrong oil can ruin a dish before it even hits the plate. This cheat sheet breaks down cooking oil smoke points so you know exactly which oil to use for searing, sautéing, or deep frying.

With Restaurant Equippers, you can master the smoke points of cooking oils in minutes. Let’s begin with the basics. 

Smoke Points of Popular Cooking Oils Explained

Smoke point is the temperature at which oil starts to smoke, break down, and release bitter flavors and harmful compounds. 

Once an oil reaches its smoke point, it stops performing well and begins to burn. And no one wants that.

High-heat cooking methods like frying or searing need oils with higher smoke points to stay safe and taste clean. That’s why knowing the smoke points of popular cooking oils helps you avoid kitchen mistakes and get better results every time. 

What Oil Has the Highest Smoke Point for Frying and Searing?

When you’re frying or searing at high heat, oil choice makes a big difference. Using a cooking oil with a high smoke point helps prevent burnt flavor, excess smoke, and wasted ingredients. 

Follow the chart below to compare the smoke points of cooking oils commonly used in commercial kitchens: 

So, what oil has the highest smoke point? Avocado oil.

Overall, these oil smoke point chart numbers help guide your oil selection, especially when cooking in hot commercial equipment like ranges, deep fryers, and cookware that push temperatures higher than home kitchens.

To hit the right temp without guessing, use a commercial-grade thermometer to monitor your oil and stay below the cooking oil smoke point.

Choosing the Best Cooking Oil with High Smoke Point

Choosing the best cooking oil with a high smoke point depends on your cooking method, flavor preferences, and how often you plan to reuse the oil. 

For deep frying or high-heat searing, choose neutral, refined oils like avocado, peanut, or safflower oil. These oils handle higher temperatures without breaking down and don’t overpower the food's flavor.

For medium-heat tasks like roasting or sauteing, canola or refined olive oil works well and offers a mild taste.

Avoid unrefined or cold-pressed oils for high-heat cooking, as they smoke earlier and degrade faster. If you need versatility, use oils with high smoke points and long shelf lives, especially in commercial kitchens where volume and consistency are key.

Finally, always check the oil label for refining information and smoke point range before buying. This helps guarantee the perfect choice.

Cooking Oil Smoke Points: FAQs

Learn more about different cooking oil smoke points through our frequently asked questions below. 

Are unrefined oils safe to use for high-heat cooking?

Unrefined oils are not ideal for high-heat cooking. They have lower smoke points and break down quickly, which can release unwanted flavors and smoke. Always choose a refined cooking oil with a high smoke point for frying, searing, or grilling. 

Can I reuse cooking oil that has reached its smoke point?

No. Once oil passes its smoke point, it starts to degrade and lose its cooking quality. Reusing it after this point can affect taste, texture, and even safety. Discard any oil that has visibly smoked or smells burnt. 

How should I store cooking oil to preserve its quality?

Store cooking oil in a cool, dark place away from heat and light. Exposure to air and temperature changes can lower the smoke point of cooking oils over time. Always seal the container tightly to prevent any oxidation.
