Acorn squash is a tasty, versatile and fantastic fall vegetable. Once cooked, it can be pureed, chopped, sliced or stuffed and used in both sweet and savory dishes. Roasting is a popular method of preparing acorn squash, but it can take up to an hour. Microwaving, though, takes less than 15 minutes to prep and cook. Perfect for weeknight cooking. Add acorn squash to soups, pies, pasta, casseroles, stir-fry, or salad for a festive fall ingredient.
