This is the easiest way to cook and extract the flesh from any winter squash, even the large, thick-skinned varieties like Hubbard and pumpkin. If the process of cutting apart a raw squash has ever seemed daunting (or scary, given the knife or cleaver required), then oven roasting whole squash will spare you that chore. Use cooked squash in purées, soups, or desserts.
Other vegetables you can use: eggplant; it will take a lot less time.
Serves 4 to 10 depending on the size of your squash.
