  • Salt (optional)

Tools Required

  • Baking sheet (for oven method)

  • Skillet (for stovetop method)

  • Air fryer (for air-frying method)

  • Toaster oven (optional for small batches)

  • Parchment paper or aluminium foil (for easy cleanup)


Roasting Methods

Oven Roasting

A simple and efficient way to get evenly roasted cashews with a deep, nutty flavour is to roast them in an oven. Set the oven temperature to 350°F (175°C) to start. To ensure uniform heat distribution, spread the raw cashews in a single layer on a baking sheet, be careful not to crowd them. To improve flavour and texture, you can decide to toss them with melted butter or olive oil.  Depending on your taste, add more flavours by adding salt, pepper, or spices like garlic powder, cinnamon, or paprika. 

To prevent overheating and guarantee even roasting, place the baking sheet in the oven and roast the cashews for ten to fifteen minutes, stirring them every five minutes. The nuts should smell toasty and turn golden brown. The cashews are taken out and allowed to cool on the baking sheet. Before storing or serving, permit them to cool fully. Roasted cashews made this way are crispy and flavourful, making them perfect for snacking or adding to food. 

Stovetop Roasting

Cashews can be rapidly and easily roasted on the stovetop to create a deliciously crunchy snack. Heat a big dry skillet over medium heat. The raw cashews should be placed in a hot skillet and scatter out evenly. To avoid burning and guarantee even roasting, it's essential to keep the cashews moving by stirring them regularly with a wooden spoon or spatula.

After 5 to 7 minutes of roasting, check the cashews often for a golden-brown colour and a nutty aroma. It's necessary to avoid over-roasting because, on the stovetop, cashews can burn quickly. Season the cashews with salt, pepper, or your favourite spices before roasting, or toss them with oil for extra flavour. Once cashews have attained a desired level of roasting, take them off the stovetop and let them cool. Roasting on the stovetop produces a crisp, fresh flavour more rapidly than roasting in an oven.

Air Fryer Method

Cashews can be roasted quickly and effectively using air frying, which uses less oil and produces a crispy texture. The air fryer must first be preheated to 175°C (350°F). Place the raw cashews in a bowl and lightly coat them with a small amount of oil (olive oil, for example). Additionally, you can add spices like paprika or garlic powder, or season with salt, pepper, and other spices.

Make sure the cashews are distributed evenly in the air fryer basket in a single layer. To guarantee even roasting, shake the basket midway through the 8–10 minutes air fry time. Pay careful attention to the cashews because they can burn if left in the air fryer for an extended period of time. Remove the cashews from the air fryer and enable them to cool when they are golden brown and flavourful. The final product is a quick and easy snack that is crunchy and evenly roasted.

Toaster Oven Method

A quick and easy way to get evenly roasted, flavourful cashews is to roast them in a toaster oven. Set the temperature of your toaster oven to 350°F (175°C) to start. On a baking tray or parchment paper-lined tray, spread the raw cashews in a single layer, and do not crowd them. If desired, mix the cashews with a small amount of oil (like coconut or olive oil) and your preferred seasonings (garlic powder, paprika, etc.).

To ensure uniform roasting, stir the cashews every five minutes while the tray is in the preheated toaster oven. Roast for roughly ten to twelve minutes. Because cashews burn easily and toaster ovens cook quickly, keep a careful eye on them. Take the tray out of the toaster oven and allow the cashews to cool after they are aromatic and golden brown. Small quantities are perfect for the toaster oven, which gives a deliciously crunchy snack.

Tips for Perfect Roasted Cashews

Preheat the Oven/Skillet: Before roasting cashews, always preheat your oven, microwave, or skillet. This guarantees that the nuts will roast uniformly once kept on the heat source.

Use the Perfect Temperature: For roasting in an oven or toaster oven, maintain the temperature at nearly 350°F (175°C). A temperature that is too high can quickly burn the cashews, while one that is too low could cause uneven roasting.

Single Layer: Arrange the cashews in the skillet or the baking sheet in a single layer. Overcrowding can result in uneven roasting because it restricts adequate heat circulation.

Stir Often: In the air fryer, stovetop, or oven, shake or stir the cashews every five minutes. This keeps things from burning and safeguards even roasting on all sides.

Oil and Seasoning: For added crunch and taste, gently rub the cashews with oil, such as melted butter or olive oil. Salt and other seasonings, such as paprika, cinnamon, or garlic powder, can also be added for variation.

Watch carefully: Cashews can burn even from being roasted a bit more than needed, so keep a close eye on them, especially in the last few minutes of roasting.

Before storing, let it cool: Allow the cashews to cool fully before putting them in an airtight container for storage. This retains its crisp texture.

Tips to Store Roasted Cashews

Cool Fully: Before storing roasted cashews, let them cool fully. This prevents moisture from accumulating inside the storage container, which could cause the cashews to become soggy and lose their crunch.

Airtight Container: To maintain their freshness and crispness, roasted cashews should be kept in an airtight container. For this, resealable plastic bags, vacuum-sealed bags, or glass jars are ideal. To keep the nuts safe from air exposure, ensure the container is closed tightly.

Maintain in a Cool, Dry Place: Keep the container out of direct sun, heat sources, and humidity.  The best place to keep the nuts from going rancid from heat or light is a pantry or cupboard.

Refrigeration for Longer Shelf Life: You want to keep your roasted cashews in the refrigerator to maintain their shelf life. In warmer climates, where storing food at room temperature can cause spoiling, this is incredibly useful.

Avoid Freezing for Short-Term Storage: Cashews' texture may be influenced by freezing, even though it can preserve their shelf life for several months. Generally speaking, it is not required unless you intend to keep them for a long time.

Confirm Freshness: Before consuming, look for any indications of spoilage in the cashews, such as a soft texture or a foul smell.  When properly stored, fresh cashews last for three weeks at room temperature or one to two months in the refrigerator.

Flavour Combinations Worth Trying

Salty and sweet: The perfect balance of sweetness and saltiness can be created by integrating a pinch of sea salt with a drizzle of honey or maple syrup. A little cinnamon can be added for warmth, making a tasty, sweet, and savoury snack.

Savoury & Spicy: For a smoky, strong taste, toss cashews with smoked paprika, cayenne pepper, and chili powder. Add some onion or garlic powder for more depth. Those who appreciate strong, tangy flavours will adore this combination.

Garlic & Herb: Sprinkle the cashews with olive oil and then season with garlic powder, thyme, and rosemary. For a flavourful snack with a Mediterranean flair, add a little parmesan to enhance the taste.  

Curry & Coconut: Combine cashews with curry powder, turmeric, and a tiny bit of coconut oil for a different twist.  To even further enhance the tropical taste and texture and generate a fragrant and tasty treat, you can indeed add shredded coconut.

Lemon & Dill: Add some fresh dill and a citrusy lemon to your cashews to make them more exciting. Those who enjoy a zesty, peppery kick will love this refreshing combination.

Sea Salt & Chocolate: Sprinkle melted dark chocolate over roasted cashews and top with crispy sea salt for a treat that reminds you of dessert. This decadent combination keeps it refined while accomplishing sweet cravings.

These combinations provide a wider spectrum of delightful roasted cashew flavours to fit any occasion and are extremely flexible to individual preferences.

Frequently Asked Questions

Q1. Are roasted cashew nuts healthy?

A balanced diet can include cashews as a healthy and nourishing snack, whether roasted or raw. Since raw cashews are more nutrient-dense and less processed, they are a healthier choice. Even so, when eaten judiciously, roasted cashews remain an amazing snack.

Does roasting cashews destroy nutrients?

Roasting nuts with heat can slightly lower their vitamin and antioxidant content. Some of their healthy fats may also be impacted by roasting. These fats can become rancid if inaccurately stored in heat or exposed to the sun for a longer duration, which will give the nuts an unpleasant taste and odour.

Can you roast nuts without oil?

It is feasible to roast nuts with or without oil, "oil-roasted" or "dry-roasted" nuts. Interestingly, the general fat content is equivalent. Nuts absorb only about 2 to 5 percent of the oil when roasted because they already contain lots of healthy fats.

How many roasted cashews can I eat?

It's easy to overeat cashews in one sitting due to their nutty and creamy flavour. To get the health advantages, limit your daily intake of medium cashews to no more than one ounce (28.35 grams). There are approximately eighteen nuts in one serving of cashews.

Is it safe to roast cashews?

Shelled cashews are safe to eat because high temperatures can be used to roast or steam them, which eradicates any aromatic oils that might have seeped into the nuts from their shells. Cashews are usually sold roasted or otherwise exposed to heat for this reason, and they are not sold in stores with their shells still on.

Are roasted cashews better than raw?

Both raw and roasted cashews are excellent choices; the manner in which they are prepared does not change their other nutritional qualities. Depending on how they are roasted, both varieties can be low in sugar and loaded with nutrients.

Do cashews need to be soaked before roasting?

Although it's not necessary, soaking before roasting could give them a crunchier texture. Additionally, soaking the cashews before would aid in the nuts' absorption of the seasonings. If soaking is your preferred choice, dip them completely in water at room temperature for approximately three hours.

How long do roasted cashews last?

There is usually a best-by date on pre-packaged cashews that tells you how long you can preserve the package in your pantry sealed. Usually, this lasts six months to a year. Roasted cashews will be maintained for two weeks in the pantry or for a month in the fridge after they are opened.

What is the difference between roasting and frying nuts?

Except for the pistachio, roasting other nuts increases their fat and calorie content. While frying does not change the fatty acid profile of cashews or pistachios, it increases the fatty acid content of almonds. Raw nuts, compared to roasted nuts, are not cooked before being packaged.
