How to Make Salt-Roasted Cashews (Oven Method)

Home-roasted cashews are better than most bagged ones for a simple reason: you control the salt and the oil, and you eat them fresh, when the crunch is at its best. The only real skills are getting the salt to stick and not walking away from the oven. Here is the method.

The salt-sticking problem

Sprinkle salt onto dry roasted cashews and most of it falls off. The salt has nothing to hold onto. There are two ways to fix that, and the first is better.

The brine method (best). Dissolve salt in a little warm water, toss the cashews in it briefly, drain, then roast. As the water evaporates in the oven, it leaves the salt bonded to the surface. This gives even, light seasoning without a greasy coating. Use about 1 teaspoon of salt dissolved in 2 tablespoons of water for 2 cups of cashews.

The oil method. Toss the cashews in a very small amount of oil, then salt. The oil holds the salt but adds fat and calories. Fine, but the brine is cleaner.

The method

1. Heat oven to 160 to 170°C (325 to 340°F). Low and slow. Cashews burn easily at higher temperatures because of their oil.
2. Season. Brine or lightly oil the cashews as above.
3. Spread in a single layer on a lined tray. Crowding steams them instead of roasting.
4. Roast 12 to 15 minutes, stirring once or twice, until golden. They colour fast at the end, so watch them.
5. Cool completely. They crisp as they cool; a warm cashew always seems softer than it will be.

Do not walk away

The single most common failure is burning, and it happens in the last few minutes. Cashews go from golden to bitter quickly, and the residual heat keeps cooking them after you take them out, so pull them a shade before they look done. Set a timer, and check at the 12-minute mark.

Flavour variations

Once you have the base, the salt is just the start:

• Chilli salt: a pinch of chilli flakes or a spicy version, like our spicy cashews
• Garlic and herb: garlic powder and dried rosemary in the brine
• Sweet-salty: a whisper of honey with the salt, roasted a touch lower

The honest note on salt

Home roasting lets you use less salt than commercial versions, which is the main health advantage. But salted cashews are still easy to over-eat, and the sodium adds up whatever you do. A 28g portion is a serving; the whole tray in front of the TV is not. The full picture on cashews, calories and sodium is in our cashew guide.

If you would rather not roast, our ready-made salt-roasted cashews are the same idea, done for you.

Storage

Cool completely, then store airtight. They keep about 2 weeks at room temperature, longer in the fridge. Any nut roasted in oil turns rancid faster, which is another reason the brine method wins. In a humid climate, keep them sealed and cool so they hold their crunch.

FAQ

How do you get salt to stick to cashews? Toss them in a light salt brine (salt dissolved in a little water) before roasting. As the water evaporates, the salt bonds to the surface. Oil works too but adds fat.

What temperature to roast cashews? 160 to 170°C (325 to 340°F). Higher burns them because of their natural oil.

How long to roast cashews? 12 to 15 minutes, stirring once or twice. Watch the last few minutes closely.

Why are my cashews soft? They crisp as they cool, so judge them cold. If still soft, they needed a few more minutes or were crowded on the tray.

Are home-roasted cashews healthier? You control the salt and oil and eat them fresh, so usually yes. They are still calorie-dense, so portion applies.
