Toasted Walnuts

If you love candied nuts, then this toasted walnuts recipe is for you! The natural flavor of the nut shines while the sticky coating adds just the right amount of sweetness.

As the walnuts cool, they become extra crunchy — perfect for snacking! It will be hard to leave them sitting on the sheet pan, but the wait is worth every second. 

Try them in our cinnamon walnut sweet bread. They are also amazing on my pear and arugula salad.

Sprinkle some over a spinach strawberry salad or homemade ice cream for a pop of sweetness and crunch.

Or, make a simple trail mix with dried cranberries or raisins and your favorite chocolate chips! 

Try these roasted walnuts in our saffron walnut rice pilaf, it is amazing!!!

Roast Walnuts In Air Fryer

Air frying is certainly the fastest method, though it will probably require a bit more clean up in the end.

  1. Combine everything together. In a large bowl, toss the nuts with olive oil, maple syrup, cinnamon, and salt until well coated.
  2. Transfer to the basket. Spread the nuts into a single layer so they toast on all sides.
  3. Cook for 8 to 10 minutes. It helps to preheat the air fryer to 320°F first, and be sure to shake the basket halfway through the cooking time. 

    It’s VERY important not to overcook them, or the sugar will burn and the toasted walnuts will taste bitter.
  4. Allow to cool completely. Once they appear golden and no longer sticky, scoop the roasted walnuts onto a baking sheet to cool.

Note: Different brands and sizes of air fryers may require different cooking times, so be familiar with your model, and make adjustments as needed.

The process is similar to air frying, except you will transfer the nuts straight to a baking sheet once coated.

  • Line your baking sheet. Parchment paper or foil makes clean up a breeze!
  • Spread nuts into a single layer. That extra space will ensure that they toast evenly.
  • Bake until golden. It will take about 8 to 10 minutes at 350°F. Check frequently once you hit the 5-minute mark. 

    Toasted walnuts can go from perfect to burnt in under a minute!
  • Don’t forget to cool! Once they are done, transfer the nuts to a new sheet pan or large plate.

    Don’t worry if they seem soft — they will continue to crisp as they cool.
