Spaghetti squash

Characteristics and culinary qualities

Raw spaghetti squash has a solid, dense texture similar to other squashes. After cooking the flesh loosens and can be scraped with a fork into strands that resemble thin pasta. The flavor is mild and slightly sweet, making it a neutral base for a wide range of sauces and seasonings. Because of its low carbohydrate and calorie content compared with wheat pasta, it is often used in gluten-free, vegetarian, and low-carb diets. Seeds can be removed, seasoned, and roasted like pumpkin seeds.

Preparation and uses

• Bake whole or halved, roast cut-side down, steam, microwave, or pressure-cook to produce strands.
• Serve topped with tomato sauce, pesto, sautéed vegetables, cheese, or meat, or use as a casserole or stuffed vegetable.
• Common in diets seeking a pasta substitute or lighter vegetable-based main course.

Nutrition and storage

Spaghetti squash is a source of dietary fiber and provides vitamins and minerals including vitamin A precursors (carotenoids), vitamin C, and potassium. Like other winter squashes, uncut fruits store well in a cool, dry place for weeks to months when harvested at maturity. Choose specimens that feel heavy for their size, have hard, unblemished rinds, and avoid soft spots.

Origin, cultivation and notable facts

Cultivars of C. pepo were developed through selection from the broad tradition of squash domestication in the Americas. Spaghetti squash itself was selected for the unusual stringy flesh rather than being a separate species. It is grown in home gardens and commercially in temperate regions where summers provide enough warmth for vines to set fruit.
