❤️ Why you will love this recipe

  • Easy: All I had to do was mix the walnuts with butter, sugar (or erythritol), vanilla extract, and cinnamon, and add them to the preheated air fryer basket.
  • Quick: This easy snack recipe is ready in less than 10 minutes, including heating the air fryer.
  • Satisfying: We all love that perfect crunch, right? Well, add a little cinnamon sugar and it really takes this crunchy snack up a level!
  • Simple ingredients: Just a few ingredients – walnuts, butter, cinnamon, white and brown sugar (or erythritol), vanilla extract, and a pinch of salt.
  • Healthy: Walnuts are so good for you! They’re rich in antioxidants, and a great source of healthy fats like omega 3s which may reduce the risk of heart disease, lower blood pressure, and may reduce inflammation. This is the perfect snack for the keto diet!
  • Keto and paleo-friendly: This recipe works with regular sugar, but I personally prefer making it with erythritol for a healthy, low carb treat.
  • Less energy: Air fryers are an excellent appliance because they’re easy to use and also they use up less energy than an oven.

🗝️ Key Ingredients & Substitutions

  • Walnuts: Whole walnuts, walnut halves, or walnut pieces all work for this recipe. I found that the walnuts didn’t fall through the holes in the air fryer basket. You can substitute pecans if you’d prefer.
  • Butter: Butter tastes so delicious with these nuts, but for a dairy-free option you can use refined coconut oil.
  • Sugar or sweetener: This recipe works with both sugar and erythritol (or premixed stevia & erythritol). I added both white sugar (or sweetener) and light brown sugar (or sweetener), however, one or the other would work too.
  • Ground cinnamon: This spice brings out the sweetness in these cinnamon sugar walnuts.
  • Vanilla: Vanilla extract adds warmth and sweetness. Skip it if you don’t have any on hand.
  • Salt: Just a pinch of salt makes all of these flavors pop!

🥣 How to make Candied Walnuts in an Air Fryer

1. Preheat the air fryer to 140 degrees C/285 degrees F.

2. Mix melted butter and walnuts: In a medium bowl, mix the raw nuts with the melted butter.

3. Mix the other ingredients: In a large bowl, mix together the remaining ingredients: white and brown sugar (or erythritol), cinnamon, vanilla extract, and salt.

4. Add them together: Add the butter-coated walnuts to the sugar mixture in the large mixing bowl and mix everything together until the walnuts have an even sugar coating.

5. Cook: Add the coated walnuts to the preheated air fryer in a single layer, and cook for 8-10 minutes, stirring or shaking the basket halfway through.

6. Cool: Remove the candied walnuts from the air fryer, spread them out on a baking sheet with a piece of parchment paper, and allow them to cool for 5-10 minutes before eating. If the walnuts are stuck together, break them up with a wooden spoon.

🫙 Storage Instructions

  • Room Temperature: Store any extra candied nuts in an airtight container like a mason jar at room temperature for up to 2 weeks. For ease, store individual portions in little bags so you can just grab them and go.
  • Fridge: If you want to keep them for even longer, pop them in the fridge for up to 3-4 weeks.
  • Freezer: Candied nuts freeze really well! You can store them in a freezer-safe air-tight container or a freezer bag in the freezer for up to 3 months.

🪄 Recipe Notes & Tips

Check your nuts: Make sure when you stir the nuts, you check them to see how “done” they are. Check them again at the 8-minute mark and if they need a couple of extra minutes then cook them just a little longer. Different brands of air fryers will heat differently, so keep an eye on them to prevent burning!

Other nuts: You can swap the walnuts and make air fryer almonds, candied pecans or even peanuts. Peanuts may cook a little quicker so keep an eye on them! I’ve also tried this with cashews and brazil nuts. They take a little longer to cook.

  1. I followed the recipe exactly but I should have done 8 min instead of 10 and they were burned! Next time I will try 8 min.

      Hi Peggy,

      I find that it’s definitely worth checking at the minimum time when following any air fryer recipe, as all air fryers are different. I also have quick check when stirring my air fryer candied walnuts at the half-way mark to see how they’re doing. Hope it works better next time for you, it’s such a tasty recipe!

      Cheers,
      Bethany
