Preheat your air fryer to 350°F (175°C) for about 3-5 minutes. Preheating ensures that the nuts start roasting immediately and evenly.

In a bowl, combine the raw macadamia nuts with olive oil if using. Toss to coat the nuts evenly.

Add salt to taste and any optional ingredients like honey or cinnamon. Mix well to ensure the nuts are evenly coated with the seasoning.

Spread the seasoned macadamia nuts in a single layer in the air fryer basket. Avoid overcrowding to ensure even roasting.

Place the basket in the air fryer and roast at 350°F (175°C) for 5-8 minutes.

Shake the basket halfway through cooking to ensure even roasting. Keep an eye on the nuts to prevent burning, as they can go from perfectly roasted to burnt quickly.

The nuts are done when they are golden brown and fragrant. If they need more time, continue roasting in 1-2 minute increments, checking frequently.

Remove the basket from the air fryer and let the macadamia nuts cool completely on a baking sheet or plate. They will continue to crisp up as they cool.

Once cooled, enjoy your perfectly roasted macadamia nuts as a snack, or use them in your favorite recipes.

Store any leftover roasted macadamia nuts in an airtight container at room temperature for up to two weeks, or in the refrigerator for up to a month.
