Oil selection for air fryers matters because different oils have varying smoke points that affect both flavor and safety. So what kind of oil do you use in an air fryer? The short answer is any oil with a high smoke point works best, like avocado, canola, or grapeseed oil.
Air fryers cook with hot circulating air, not deep oil. But a light coating of oil still helps food crisp up and taste better.
Below you’ll find the best oils, oils to avoid, and simple tips for using them right.
What Kind Of Oil Do You Use In An Air Fryer
The best oil for an air fryer is one with a high smoke point. Smoke point is the temperature where oil starts to burn and smoke.
Air fryers usually run between 300°F and 400°F. If your oil burns at a lower temp, it can turn bitter and create harmful compounds.
So you want oils that stay stable at high heat.
Top Oils With High Smoke Points
These oils handle air fryer heat well and have neutral or mild flavors:
- Avocado oil: smoke point around 520°F. Great all-purpose pick.
- Canola oil: smoke point around 400-450°F. Cheap and easy to find.
- Grapeseed oil: smoke point around 420°F. Light taste.
- Peanut oil: smoke point around 450°F. Adds a subtle nutty note.
- Safflower oil: smoke point around 440°F. Neutral flavor.
- Sunflower oil: smoke point around 440°F. Common and affordable.
- Vegetable oil: smoke point around 400-450°F. Widely available.
Any of these will work for most air fryer recipes. Avocado and canola are the two safest bets.
Oils You Should Avoid In An Air Fryer
Some oils have low smoke points. They burn fast at air fryer temps.
- Extra virgin olive oil: smoke point around 350-410°F. Can smoke at high heat.
- Butter: smoke point around 300-350°F. Burns quickly.
- Coconut oil: smoke point around 350°F. Not ideal for high heat.
- Toasted sesame oil: smoke point around 350°F. Better for finishing, not cooking.
That said, extra virgin olive oil can work if you keep the temp under 350°F. Just watch it closely.
Does The Type Of Oil Really Matter
Yes, it does. Two main reasons:
- Safety: low smoke point oils can release acrolein, a compound linked to irritation.
- Flavor: burnt oil tastes bad and ruins your food.
High smoke point oils stay clean and neutral. Your food tastes like food, not burnt oil.
How Much Oil Should You Use
You need very little. Air fryers don’t need much oil to work.
- Light coating: 1 to 2 teaspoons for most recipes.
- Spray bottle: best way to control amount.
- Avoid aerosol sprays: they can damage the nonstick coating over time.
Too much oil can pool and cause smoke. A thin, even layer is all you need.
Best Way To Apply Oil In An Air Fryer
Follow these simple steps:
- Pat your food dry with a paper towel.
- Put food in a bowl and drizzle a small amount of oil.
- Toss to coat evenly.
- Or use a oil spray bottle and mist the food lightly.
- Don’t spray oil directly into the air fryer basket while it’s hot.
Even coating helps browning. Uneven oil means uneven crisp.
Can You Use Olive Oil In An Air Fryer
Yes, but with a catch. Regular olive oil has a higher smoke point than extra virgin. Regular olive oil sits around 465°F.
Extra virgin olive oil is lower, around 350-410°F. If your recipe runs at 375°F or higher, use regular olive oil instead.
Or save the extra virgin for lower temp cooking and finishing.
What About Spray Oils
Store-bought cooking sprays often contain propellants and additives. Some can leave a sticky residue on your air fryer basket.
Better option: buy a refillable oil sprayer. Fill it with your favorite high smoke point oil.
This gives you control and avoids mystery ingredients.
Does Oil Affect Crispiness
A little oil helps browning and texture. But oil isn’t the main driver of crispiness in an air fryer.
Hot air does most of the work. Oil just helps the surface brown and prevents dryness.
If you want extra crunch, a light starch coating plus a small amount of oil works well.
Flavored Oils And Infused Oils
Flavored oils can be tricky. Some contain garlic, herbs, or chili. These bits can burn at high heat.
If you use infused oil, strain out solid pieces first. Or add flavor after cooking.
Plain high smoke point oils are the safest choice for cooking.
Quick Comparison Table
- Avocado oil: 520°F, neutral, great for all recipes.
- Canola oil: 400-450°F, neutral, budget friendly.
- Grapeseed oil: 420°F, light, good for frying.
- Peanut oil: 450°F, mild nutty taste.
- Extra virgin olive oil: 350-410°F, use at lower temps.
- Butter: 300-350°F, avoid high heat.
- Coconut oil: 350°F, not ideal for high heat.
Storage And Freshness
Oil goes bad over time. Heat, light, and air speed up spoilage.
- Store oil in a cool, dark place.
- Keep the cap tight.
- Use within six months of opening for best quality.
- Smell it before use. If it smells off, toss it.
Rancid oil tastes bad and won’t help your food.
Common Mistakes To Avoid
- Using butter at high heat. It burns fast.
- Over-oiling food. It causes smoke and soggy results.
- Using aerosol sprays. They can harm the nonstick coating.
- Ignoring smoke point. It matters more than flavor.
- Reusing oil from the basket. Air fryer oil doesn’t recycle well.
Keep it simple. Pick one high smoke point oil and use it lightly.
Final Takeaway
For most air fryer cooking, avocado oil and canola oil are the best picks. They handle high heat without burning.
Grapeseed, peanut, safflower, and sunflower oil are also solid choices. Avoid butter, coconut oil, and extra virgin olive oil at high temps.
Use a light hand. A teaspoon or two is plenty. A refillable spray bottle helps you control the amount.
Pick the right oil, use it sparingly, and your air fryer food will come out crisp and clean tasting every time.
