Instructions

1. Place the oven rack in the center position and preheat to 350 degrees Fahrenheit. Spray a rimmed, shallow roasting pan with vegetable oil cooking spray and set aside.

2. Wash the green peanuts thoroughly in warm water to remove any excess dirt or debris and place them on clean paper towels. Allow the nuts to dry completely before roasting.

3. Place the peanuts in a single layer in the bottom of the prepared roasting pan. Place the pan in the oven and roast for 20 to 25 minutes, or until the shells are golden brown, crisp and dry.

4. Test for doneness after about 15 minutes by removing a peanut, allowing it to cool enough to handle, and then cracking it open. Check if the skin is flaky and dry, and the peanut flesh is lightly colored and easy to snap with your fingers.

5. Continue roasting if the green peanuts are not yet done, and check again every 5 minutes until they almost reach the desired doneness. Remove the peanuts from the oven a few minutes before they are done, as the nuts will continue to cook while cooling.

6. Allow the roasted peanuts to cool for at least 30 minutes before consuming. Store leftovers in a brown paper bag in the refrigerator for up to one week or at room temperature for up to three days.
