Tips For Making The Best Air Fryer Walnuts

  • Use the freshest walnuts you can get your hands on. Make sure you check the expiry date as well. Look for plump walnuts for the best flavor.
  • Soaking the walnuts will help remove the Phytic acid from the nuts. Phytic acid interferes with mineral and vitamin absorption in your gut – soaking the nut will prevent this. But keep in mind that you will have to cook your walnut at 350 Fahrenheit for about 20 minutes in case of an overnight soak.
  • Shake or stir the walnuts during the cooking process to ensure they cook evenly. This helps to prevent any burnt spots. Also, it’s best to spread them in a single layer in the air fryer basket for an even cooking process.
  • After the walnuts are done cooking, allow them to cool down completely. This will keep them crunchy in their air-tight containers. 


How can we prevent walnuts from sticking to each other?

Most recipes do not use a lot of sugar or sweet syrups. So, this might not be an issue but if you’re still wary, it’s best to shake the air fryer basket halfway through the cooking time. 

Can we freeze air fryer roasted walnuts?

Yes, you can freeze your air fryer walnuts in a dry, clean, airtight container in the freezer for up to 2-3 months. The roasted walnuts will probably go bad after that and you must throw it away in case of mold.

Why did my candied walnuts not turn crispy?

If your air fryer walnuts did not turn crispy, it may be because the glaze is taking time to set when it’s hot. Walnuts will turn harder once cooled down completely. If the walnuts are still soft then you may have overfilled the air fryer tray. Be sure to spread apart the walnuts when cooking. 

Also, you can put the soft walnuts back in to cook for a few more minutes and they’ll come out crispy.  


Air fryer walnuts are a quick, easy, and nutritious snack that you can make whenever. They are a good alternative to the unhealthy treats we consume – just imagine how many pies, cookies, ice creams, and sweets you can top off with these delicious nuts.

Air fryer walnuts are sure to leave you warm and toasty with every bite. So, take your fryer out, gather your ingredients, and get ready to enjoy the ultimate snack.
