Spaghetti squash is a type of winter squash that has a unique, stringy flesh resembling spaghetti when cooked. It is typically oval or oblong in shape and has a hard, yellow skin. When baked or boiled, the flesh separates into long strands, making it a popular low-carb alternative to traditional pasta. This vegetable is rich in vitamins A and C, as well as fiber, making it a nutritious addition to meals. Spaghetti squash can be prepared in various ways, including roasting, steaming, or microwaving, and is often served with sauces, vegetables, or proteins for a healthy dish.
