As with all winter squashes, such as pumpkins, butternut squash seeds are edible in either a raw or roasted form. Butternut squash is a gourd known for its elongated shape, orange flesh, and tough yellow skin.
Roasting winter squash seeds like butternut squash adds a deeper flavor to them. The seeds are tossed with vegetable oil, salt and sometimes spices and roasted on a pan in a 300 degree Fahrenheit oven until the seeds start to brown, or about 20-25 minutes.
