Roasting cashews transforms their naturally creamy, buttery flavor into a deeply aromatic, slightly caramelized nutty delight. Whether you are preparing them as a snack, adding them to a salad, or using them in a savory dish, roasting brings out the best in cashews. Traditionally, roasting nuts was a time-consuming process that required careful attention in an oven or on the stovetop. However, the air fryer has revolutionized this process. With its rapid hot-air circulation, the air fryer allows for evenly roasted nuts in a fraction of the time, while preserving their natural oils and enhancing flavor. This guide will walk you through everything you need to know about achieving perfectly roasted cashews, from temperature and timing to troubleshooting and expert tips.
The key to perfectly roasted cashews lies in temperature control. Cashews are sensitive to heat; too low a temperature results in a pale, soft nut, while too high can lead to burnt edges and bitterness. The ideal air fryer temperature for roasting cashews is 325°F (163°C).
At this temperature, the cashews roast evenly, allowing their natural oils to release slowly, creating a subtle golden-brown color and a rich aroma. This temperature strikes a balance between thorough roasting and maintaining the delicate texture of the nut. Some air fryer models may have hotspots, so shaking or stirring the cashews halfway through is recommended to ensure uniform roasting.

Time is just as crucial as temperature. For raw cashews, the typical roasting duration in an air fryer is 8-12 minutes. This range depends on the size of the cashews, the amount in the basket, and your air fryer model.
It’s essential to check the nuts periodically, as cashews can go from perfectly roasted to burnt very quickly due to their high oil content. Shaking the basket or stirring the nuts every 3-4 minutes promotes even roasting and prevents scorching.
Determining doneness is not just about color-it involves aroma, texture, and taste:
To roast cashews in an air fryer, you’ll need:
Note: Cashews have natural oils and can roast without added oil, but a light coating helps seasonings stick and intensifies the roasted flavor.
Adjusting the temperature changes the roasting outcome significantly:
If experimenting with temperature, always check the nuts frequently to prevent over-roasting.
Cooking time variations affect texture and flavor:
Timing adjustments must also consider batch size; larger amounts need slightly longer roasting due to crowded baskets reducing airflow.
Even in the air fryer, roasting can go awry:
Understanding these common pitfalls allows quick correction before ruining an entire batch.
For roasting cashews in an air fryer, set the temperature between 325°F to 350°F (160°C to 175°C). This range allows the nuts to roast evenly without burning, preserving their natural oils and flavor.
Roasting cashews in an air fryer typically takes 8 to 12 minutes, depending on the size of the nuts and the specific air fryer model. It is important to shake the basket halfway through to ensure even roasting.
Preheating is recommended for consistent results. Preheat your air fryer for about 3 to 5 minutes before adding the cashews to ensure even heat distribution.
Adding a small amount of oil is optional; about 1 teaspoon per cup of cashews can enhance browning and flavor. Seasonings like salt, cinnamon, or chili powder can be added before roasting for a customized taste.
Cashews are done when they are golden brown, fragrant, and slightly crisp to the touch. They continue to cook slightly from residual heat after being removed from the air fryer, so avoid over-roasting.
Raw cashews and unsalted cashews can be roasted directly. Salted cashews should be monitored closely as they can brown more quickly due to the salt. Reduce the temperature slightly or shorten the cooking time if needed.
Allow the cashews to cool completely, then store them in an airtight container at room temperature for up to two weeks. For longer storage, refrigerate or freeze to maintain freshness and prevent rancidity.
