What is the best oil for an air fryer?
Avocado oil is the top choice thanks to its high smoke point (520°F) and mild, neutral flavor. Other great options include light olive oil, grapeseed oil, and peanut oil depending on the food you are cooking.
Is oil actually necessary when using an air fryer?
Yes, you generally need a small amount of oil when cooking in an air fryer to get crispy, flavorful results. While air fryers use rapidly circulating hot air to cook your food, a light coating of oil conducts that heat more efficiently. This thin layer prevents sticking, promotes even browning, and creates that signature golden-brown crunch.
There is a distinct difference between “low oil cooking” and “no oil cooking.” No oil cooking works for certain pre-packaged frozen foods that already contain fats, but fresh ingredients will dry out without a little help. Low oil cooking uses just enough fat to mimic deep frying. If you are serious about low oil cooking, you can check out our Beginner’s Guide to Air Frying to find the best air fryers designed specifically for minimal oil usage.
Best Oil for Different Foods (IMPORTANT)
| Food Type | Best Oil for Air Fryer | Notes / Why It Works |

| Frozen Foods | No Oil Needed | Already contains fat; prevents soggy texture |
Pro Tip: Use 1–2 tsp oil for fresh foods. For frozen items, skip oil to avoid mess and maintain crispiness.
Why High Smoke Point Oils Matter
The “smoke point” refers to the temperature at which an oil starts to break down and release visible smoke. Since most air fryers operate between 390°F and 400°F, choosing a high smoke point oil is essential for safe and effective cooking.
When oil is heated beyond its smoke point, it starts to degrade. This process releases harmful compounds and free radicals that can negatively impact your health. At the same time, it produces acrid smoke that gives your food a bitter, burnt taste.
Scientific Insight
At high temperatures, the fats in cooking oils break down into compounds such as acrolein, which is responsible for the sharp smell and unpleasant flavor in overcooked food. This is why low smoke point oils—like extra virgin olive oil—are not suitable for air fryer cooking.
Practical Tip
Always choose oils with a smoke point above 400°F (like avocado oil or light olive oil) to ensure:
- Better flavor
- No excess smoke
- Safer cooking

Oils to Avoid in Your Air Fryer
Not all fats are created equal. The following oils will ruin your food, smoke up your kitchen, or damage your machine at high temperatures:
- Extra Virgin Olive Oil: Burns at 325°F to 375°F. It will quickly turn your food bitter.
- Butter: Milk solids in butter burn rapidly at high heat. If you want a buttery flavor, use clarified butter (ghee) instead.
- Unrefined Sesame Oil: Perfect for drizzling over finished dishes, but it burns instantly in an air fryer.
- Aerosol Cooking Sprays: As mentioned, the propellants destroy your air fryer basket.
How Much Oil Should You Use? (And How to Apply It)
You should use between 1 to 2 teaspoons of oil for most fresh foods cooked in an air fryer. The goal is to provide a very light, even coating rather than drowning the ingredients in fat.
Here is a quick cheat sheet for different types of meals:
- Fresh veggies: Toss 1 to 2 teaspoons of oil with your vegetables in a mixing bowl before transferring them to the basket.
- Frozen foods (like fries or chicken nuggets): No oil needed. These pre-packaged foods already contain oil from the manufacturing process.
- Breaded meats: Give the breading a light spritz using the best oil spray for air fryer cooking. This ensures there are no dry, powdery spots of flour left on your chicken.
Practical Tip: Always apply oil directly to the food, not to the basket!
Common Air Frying Mistakes to Avoid
Even with the best high smoke point oils, a few simple errors can ruin your meal. Avoid these common mistakes:
- Overcrowding the basket: If you stack food on top of each other, the hot air and oil cannot circulate. Your food will steam rather than crisp up. Cook in batches for the best crunch.
- Using too much oil: Pouring a heavy glug of oil into the basket leads to soggy, greasy food. Less is more when air frying.
- Skipping the shake: You must toss your vegetables or flip your meat halfway through the cooking time. This ensures the oil coats everything evenly and prevents one side from burning.
Frequently Asked Questions (FAQ)
Is it safe to add oil directly to the air fryer?
No, you should never pour oil directly into the bottom of the air fryer basket. Excess oil will drip down into the heating element and cause heavy smoking. Always toss your food with oil in a separate bowl or use a spritzer to lightly mist the ingredients.
Is vegetable oil safe for air fryers?
Yes, standard vegetable oil is safe for air fryers. It typically has a smoke point of around 400°F and an incredibly neutral flavor. However, avocado oil or extra light olive oil offer far better nutritional profiles and healthier fats.
Why is my air fryer smoking?
Your air fryer is likely smoking because you used an oil with a low smoke point, or excess grease from fatty foods (like bacon) has collected in the bottom pan. Always use high smoke point oils and clean your basket thoroughly between uses.
