Roasting cashews in an air fryer is a fast, healthy, and delicious way to enhance their natural flavor and crunch. With minimal oil and just 8–12 minutes of cooking time, you’ll get golden, aromatic nuts that are perfect for snacking or adding to meals.
If you’ve ever stood over a hot stove, stirring raw cashews in a pan and hoping they don’t burn, you’ll love this simpler way to roast them. Roasting cashews in an air fryer is not only faster and safer but also delivers consistently delicious results. Whether you’re a seasoned home cook or just starting out, this method is foolproof and perfect for busy weeknights or last-minute snack cravings.
Cashews are naturally creamy and mild, but roasting brings out their rich, buttery depth and adds a satisfying crunch. Traditionally, people roast nuts on the stovetop or in the oven, but both methods require constant attention and can lead to uneven results. The air fryer changes the game. With its powerful convection heating, it circulates hot air around the nuts, ensuring even browning and eliminating the need for constant stirring. Plus, you use far less oil—sometimes none at all—making this a healthier alternative without sacrificing flavor.

Why Roast Cashews in an Air Fryer?
The air fryer has become a kitchen staple for good reason. It’s versatile, energy-efficient, and perfect for small-batch cooking. When it comes to roasting nuts like cashews, it offers several advantages over traditional methods.
Even Heat Distribution
Unlike a stovetop pan where heat comes from the bottom, air fryers use rapid air circulation to cook food evenly from all sides. This means your cashews won’t end up with burnt edges and raw centers. You get uniformly golden nuts every time.
Less Oil, Same Flavor
Raw cashews have a soft texture and mild taste. Roasting enhances their natural oils, bringing out a rich, nutty flavor. You don’t need much oil—just a light spray or a teaspoon tossed in—to achieve that perfect crunch. In fact, many people roast cashews in the air fryer with no oil at all and still get excellent results.
Faster Than the Oven
Preheating an oven takes time, and roasting cashews can take 15–20 minutes. In an air fryer, you’re looking at 8–12 minutes total, including preheating. That’s a huge time saver, especially when you’re craving a quick, healthy snack.
Easy Cleanup
No greasy stovetop or baking sheet to scrub. Most air fryer baskets are non-stick and dishwasher-safe, so cleanup is a breeze. Just wipe down the basket or toss it in the dishwasher, and you’re done.
Ingredients and Equipment You’ll Need
One of the best things about roasting cashews in an air fryer is how simple it is. You don’t need fancy tools or a long list of ingredients.
Basic Ingredients
- 1 cup raw cashews (unsalted, unroasted)
- 1 teaspoon oil (optional—use olive, avocado, or coconut oil)
- Salt to taste (about ¼ teaspoon)
You can keep it simple with just salt, or get creative with seasonings like garlic powder, smoked paprika, cinnamon, or a drizzle of honey.
Equipment
- Air fryer (any model works—basket or tray style)
- Mixing bowl
- Measuring spoons
- Tongs or a spoon for stirring
No need for parchment paper or foil—just place the cashews directly in the air fryer basket. However, if you’re worried about small pieces falling through the grate, a light spray of oil on the basket can help prevent sticking.
Step-by-Step Instructions
Roasting cashews in an air fryer is straightforward, but a few tips will help you get the best results.
Step 1: Preheat the Air Fryer
Set your air fryer to 320°F (160°C) and let it preheat for 3–5 minutes. Preheating ensures even cooking from the start. While some models don’t require preheating, doing so helps the cashews roast more consistently.
Step 2: Prepare the Cashews
In a mixing bowl, toss the raw cashews with oil (if using) and salt. Stir well to coat evenly. If you’re adding spices or sweeteners, mix them in now. For example, try ¼ teaspoon garlic powder and a pinch of cayenne for a spicy kick, or 1 tablespoon honey and a dash of cinnamon for a sweet treat.
Step 3: Arrange in the Basket
Spread the cashews in a single layer in the air fryer basket. Don’t overcrowd them—this allows hot air to circulate freely. If you’re roasting a large batch, cook in two rounds to avoid steaming instead of roasting.
Step 4: Roast and Stir
Air fry for 6 minutes, then open the basket and stir the cashews with tongs or a spoon. This ensures even browning. Return to the air fryer and cook for another 2–4 minutes, depending on your desired level of doneness.
Step 5: Cool and Store
Once golden and fragrant, remove the cashews and let them cool completely on a plate or baking sheet. They’ll crisp up as they cool. Store in an airtight container at room temperature for up to two weeks.
Tips for Perfect Roasted Cashews
Even with a simple recipe, small details make a big difference.
Don’t Overcook
Cashews can go from golden to burnt very quickly. Start checking at the 8-minute mark, especially if you’re using a powerful air fryer. The residual heat will continue cooking them slightly after removal.
Use a Light Hand with Oil
Too much oil can make the cashews greasy instead of crispy. A light spray or a teaspoon is plenty. If you’re avoiding oil altogether, the air fryer’s dry heat still works well.
Experiment with Flavors
Once you master the basics, try different flavor combinations:
- Savory: Garlic powder, onion powder, smoked paprika, and a pinch of salt
- Sweet: Cinnamon, nutmeg, and a drizzle of maple syrup
- Spicy: Chili powder, cayenne, and lime zest
- Umami: Soy sauce, sesame oil, and a sprinkle of sesame seeds
Let your taste buds guide you—roasting cashews in an air fryer is a great way to personalize your snacks.
Batch Cooking Tip
If you’re making a large quantity, roast in small batches. Overloading the basket traps steam and leads to soggy nuts. It’s better to cook two smaller batches than one large, uneven one.
Serving and Storage Ideas
Roasted cashews are incredibly versatile. Here’s how to enjoy them:
As a Snack
Keep a jar of plain or lightly salted roasted cashews on hand for a quick, protein-rich snack. They’re perfect for road trips, lunchboxes, or afternoon energy boosts.
In Salads
Add a handful to green salads, grain bowls, or fruit salads for crunch and healthy fats. Try them in a kale salad with apples and a lemon vinaigrette.
In Stir-Fries
Toss roasted cashews into vegetable or chicken stir-fries during the last minute of cooking. They add texture and absorb the savory sauces beautifully.
In Baking
Chop them up and use in cookies, energy bars, or granola. Their rich flavor pairs well with chocolate, coconut, and dried fruit.
As a Topping
Sprinkle over oatmeal, yogurt, or ice cream. A few cashews can elevate a simple breakfast or dessert.
For storage, keep roasted cashews in an airtight container in a cool, dry place. Avoid the fridge or freezer unless you plan to store them long-term—moisture can make them lose their crunch.
Frequently Asked Questions About Air Fryer Cashews
Many people have questions when trying this method for the first time. Here are some common concerns and answers.
Can I roast cashews without oil?
Yes! The air fryer’s dry heat is enough to toast cashews without any oil. The natural oils in the nuts will release during roasting, giving them a rich flavor and crisp texture.
What temperature should I use?
320°F (160°C) is ideal. Higher temperatures can cause burning, while lower ones may not crisp the nuts properly. This moderate heat allows for even roasting.
How do I know when they’re done?
Roasted cashews should be golden brown and smell nutty and fragrant. They’ll crisp up as they cool, so don’t wait for them to be hard while hot.
Can I roast other nuts in the air fryer?
Absolutely! Almonds, walnuts, pecans, and peanuts all roast beautifully in the air fryer. Adjust the time slightly—larger nuts may need a few extra minutes.
Why are my cashews still soft after roasting?
This usually happens if the basket was overcrowded or the temperature was too low. Ensure the cashews are in a single layer and the air fryer is preheated.
Can I reheat store-bought roasted cashews?
Yes! If your roasted cashews have lost their crunch, reheat them in the air fryer at 300°F for 2–3 minutes. This restores their crispness without burning.
