  • Walnuts: My favorite brand of walnuts is from Costco, so grab a huge bag next time you go! Or, if you don’t have one near you, you can pick up a pack from Amazon.
  • Butter: I like unsalted butter for these — I find salted sticks to be a little too salty, so I like to add the extra pinch myself.
  • Pure Vanilla Extract: For a touch of warm flavor. Walnuts and vanilla pair so well together.
  • Sugar: I use both granulated sugar and brown sugar for my candied walnuts air fryer recipe! Alternatively, you can use only granulated.
  • Cinnamon: It wouldn’t be a candied nuts recipe without some added cinnamon in my opinion! It’s spicy in the best way.

Step 4: Air fry

Place the coated walnuts in the air fryer basket and set the temperature to 200 degrees F. Air fry for 8-10 minutes, shaking the basket frequently during the process so the nuts cook evenly. Let your air fryer walnuts cool a bit before serving, and enjoy!

Candied Walnuts Air Fryer Pro Tips

  • Walnut Prep: Make sure to dry the nuts with clean paper towels before you add the coating! Otherwise, they may not caramelize like you want them to.
  • Add extra spices that you like. I used ground cinnamon, but you can easily make them with chili powder or ground cumin.
  • Toss Well: Make sure all of the walnuts are well-coated with the butter mixture. This way, when the heat hits them, they roast evenly.
  • Prevent Sticking: You can lightly spray your air fryer basket with cooking spray so that the walnuts don’t stick if you’d like.
  • Avoid Overcrowing: Arrange the candied walnuts in air fryer in a single layer for the best results. They’ll cook more evenly if there is enough room for the hot air to circulate.
  • Remember to shake the basket several times as the nuts cook. This is the trick to making candied nuts in the air fryer! It ensures they cook up evenly on all sides so they become crispy when cooled.
  • Adjust if Needed: All air fryers are different, and walnuts may vary in size. Start at 200 degrees F for about 8 minutes and adjust the temperature and air frying time if needed.
  • Let Them Cool: The air fryer candied walnuts will be very hot and sticky when they’re done. I like to cool them on a wire rack so they harden and crisp up before storing.
  • Air fried candied walnuts make for great gifts. Place them in small glass jars with a pretty ribbon for a nice presentation.
  • Storage: Store your nuts in an airtight container in a cool, dark place like your pantry. They should keep for up to 1 week. Otherwise, they will start to get soft. I would avoid putting them into the refrigerator, as the butter will harden them. If you need to store them for longer, you can freeze them for up to 3 months.

Air Fryer Candied Walnuts FAQs

Are glazed and candied walnuts the same?

Almost, although glazed walnuts are often made with corn syrup. Since I knew the air fryer would not cook corn syrup well, I used butter and white sugar to make them candied. The two snacks taste about the same!

Should I soak walnuts before cooking?

I typically don’t soak my walnuts before air frying, but I know some others swear by it for extra crunchy results. If you’d like to try it, you can soak the nuts for about 10-15 minutes before you add the cinnamon-sugar coating. Just remember to dry them very well.

How do you keep the walnuts from sticking?

Since we’re not using corn syrup in my candied walnuts air fryer recipe, they won’t stick like some others can. I also find that shaking the basket really helps keep them separated.

Why are my candied walnuts soft?

It’s important to let them cool completely before storing them! The nuts need that extra time to fully harden and caramelize. If you add them to an airtight container when they’re still warm, the condensation will cause them to soften.

Do candied walnuts go bad?

Yes, all candied nuts go bad after a while — after about a week, the butter begins to break down. You shouldn’t run into this problem because you’re making such a small batch in your air fryer, and these go fast! However, if you’re worried about not using them within a week, feel free to cut the recipe in half for an even smaller batch.
