An extended shelf life means you can prepare them in advance for giving as edible gifts! Homemade gifts say, “I’m thinking of you and you are special!” All of these things add up to a fun recipe, in my opinion.

Tips For Success

  • Choose shelled raw walnuts and check the pieces for any bits of shell before cooking. 
  • Spread walnuts in a single layer on a rimmed baking sheet. This ensures even toasting and allows the heat to reach all sides of the nuts.
  • Cover the cookie sheet with parchment paper for easy cleanup.
  • Nuts can quickly go from golden to burnt; keep a close eye during the toasting process.
  • The walnuts should turn golden brown and become aromatic.
  • Skip added oils; walnuts have natural oils that intensify during toasting.
  • Transfer hot walnuts to a cool surface to stop the toasting process and avoid overcooking.
  • It’s often better to toast walnuts in smaller batches rather than trying to toast a large quantity all at once. This ensures that each walnut gets evenly toasted.
  • Trust your senses; a fragrant, nutty aroma indicates they’re perfectly toasted.

Delicious Variations 

  • Swap cooking methods. We are including instructions for air frying and for skillet cooking walnuts in case you prefer either of those. 
  • Make them sweet and spicy. Toss toasted walnuts with honey, cinnamon, and a pinch of cayenne for a delightful mix of sweet and spicy.
  • Add a garlic parmesan crunch. Combine toasted walnuts with grated Parmesan cheese and a hint of garlic powder for a savory, cheesy crunch.
  • Add a curry blend. Create an exotic twist by dusting toasted walnuts with curry powder and a pinch of sea salt.

Prep And Storage

  • Prep Ahead – You can prep these ahead of time or serve straight from the oven since it’s a quick cook. 
  • Store – Store at room temperature in an airtight container for 2 weeks, and in the fridge for up to 4 weeks.
  • Freeze – Toasted walnuts will keep for up to 6 months in the freezer. 
  • Reheat – Thaw to room temperature or reheat under the low broiler until warm and crispy again.

    So delicious. My family love it. So my all-time favorite Mario game is still super mario bros wonder. Furthermore, since SMW has always been associated with Mario World, I’ve learnt that people would start to misinterpret it.
