Heat a skillet or pan over medium heat. Once the pan is warm, pour in the walnuts. While stirring often, heat walnuts until slightly golden and fragrant, about 2-4 minutes.
Notes
Walnut has a high-fat content that can make them burn quickly, so be sure to keep a close eye on them and stir often/constantly shake the pan.
To store: Allow the walnuts to cool to room temperature. Then, transfer the walnut pieces in an airtight container or reusable silicone bag. They’ll keep for up to a week.
