5 Best Oils for Air Fryer: The Ultimate Guide for Crispy, Healthy Results
So, you’ve finally joined the revolution and bought a digital air fryer. You’ve read our benefits of using an air fryer guide, and you’re ready to cook. But there is one crucial ingredient that stands between you and that perfect, golden-brown crunch: Oil.
Contrary to popular belief, air frying isn’t always “oil-free.” It uses significantly less oil than deep frying, but the right oil is essential for heat transfer, flavor, and achieving that Maillard reaction (browning). Choosing the wrong oil can lead to a smoke-filled kitchen, burnt flavors, and potentially harmful compounds.
Quick Summary: The Winners
- Best Overall: Avocado Oil (High Smoke Point & Neutral Flavor)
- Best for Flavor: Light Olive Oil (Not Extra Virgin!)
- Best Budget: Canola or Vegetable Oil
- Best for Sweets: Coconut Oil
- Best Spray: Pump-Style Sprayers (Avoid aerosols)
Why Smoke Point Matters More Than Anything
Before we dive into the products, we need to talk science for a second. The Smoke Point is the temperature at which an oil stops shimmering and starts smoking. When oil smokes, it breaks down, releases free radicals (bad for health), and makes your food taste bitter.
Air fryers typically operate between 350°F and 400°F (175°C – 205°C). Therefore, you need an oil with a smoke point above 400°F. This is why standard butter or Extra Virgin Olive Oil often fail in air fryers. If you are confused about temperature settings, check out our guide on air fryer temperature control.
Detailed Review: The 5 Best Oils for Your Air Fryer
BetterBody Foods 100% Pure Avocado Oil
Avocado oil is the undisputed king of air frying. With a smoke point of 500°F, it can withstand the intense circulating heat of even the most powerful units like the NuWave IQ360 Pro.
It has a very neutral flavor, meaning your fries will taste like potatoes, not avocado. It’s also rich in monounsaturated fats (the heart-healthy kind).
Pompeian Extra Light Tasting Olive Oil
Wait, didn’t we say no Olive Oil? We said no Extra Virgin Olive Oil. “Extra Light” olive oil is more refined, giving it a higher smoke point (around 410°F) compared to EVOO (375°F).
This allows you to get some of the health benefits of olive oil without the smoke. It works beautifully for Mediterranean-style veggies or chicken breast. If you are trying out new air fryer recipes for beginners, this is a forgiving oil to start with.
Nutiva Organic Steam-Refined Coconut Oil
If you are using your air fryer for baking—perhaps making muffins in a digital toaster oven air fryer combo—coconut oil is fantastic.
Standard coconut oil tastes like coconut, which is great for sweets. However, this Nutiva version is “refined,” meaning it has a higher smoke point (400°F) and a neutral scent, making it versatile for savory dishes like shrimp or tofu as well.
Baja Precious – Grapeseed Oil
Grapeseed oil is a byproduct of winemaking. It is incredibly light and has a moderately high smoke point (420°F). Because it is so thin, it coats food evenly without making it soggy.
This is our top recommendation if you are trying to replicate deep-fried textures. It works perfectly with standard baskets or even when using fryer strainers for smaller items.
4th & Heart Original Grass-Fed Ghee
Ghee is clarified butter—butter that has had the milk solids removed. Because the solids (which burn) are gone, Ghee has a smoke point of 485°F!
It adds a rich, buttery taste that oil simply cannot match. It is incredible on corn on the cob, steak, or even reheating pizza. It’s a true smart lifestyle upgrade for keto or paleo dieters.
Comparison Table: Smoke Points at a Glance
| Oil Type | Smoke Point (°F) | Flavor Profile | Best Application |
|---|---|---|---|
| Avocado Oil | 520°F | Neutral | All-purpose, High Heat |
| Ghee | 485°F | Buttery | Meats, Vegetables |
| Light Olive Oil | 465°F | Mild | Mediterranean dishes |
| Grapeseed Oil | 420°F | Neutral | Ultra-Crispy Fries |
| Coconut Oil (Refined) | 400°F | Neutral | Baking, Seafood |
| Butter (Avoid) | 302°F | Rich | Adding after cooking |
Expert Tip: The Application Method
How you apply the oil is just as important as the oil you choose. Do not use non-stick aerosol sprays (like Pam) directly on your air fryer basket.
Many commercial sprays contain soy lecithin, which can build up on the non-stick coating of your air fryer basket and cause it to peel over time. This is a common issue discussed in our air fryer cleaning guide.
The Solution: Oil Spritzers
Invest in a quality glass oil mister. This allows you to put your high-quality Avocado oil inside and spray a fine mist without the harmful propellants. It’s an essential tool alongside your best measuring cups and kitchen scales.

Frequently Asked Questions (AEO Optimized)
Can I use Extra Virgin Olive Oil in my air fryer?
It is not recommended for high temperatures (above 375°F). EVOO smokes easily, which can ruin the flavor of your food. Use Light Olive Oil or Avocado Oil instead.
How much oil should I use?
Usually, 1 to 2 teaspoons is enough for a basket of fries. The beauty of the digital air fryer is the air circulation does the heavy lifting. Toss your food in a bowl (we recommend checking our best mixing bowls review) with the oil to coat evenly before frying.
Is an air fryer healthy with oil?
Yes. Compared to deep frying, which submerges food in oil, air frying reduces fat content by up to 75-80%. It’s a massive lifestyle upgrade for calorie counters.
Conclusion
Choosing the right oil is the secret weapon for air fryer mastery. Avocado Oil stands out as the champion for its high heat tolerance and health benefits, but Ghee and Grapeseed Oil have their specific places in your culinary arsenal.
