Health Benefits of Spaghetti Squash
Continue reading to discover how spaghetti squash can enhance your overall well-being.
Strengthens Immune System
Kimberly Varner, a dietitian at Weis Markets, encourages people to add spaghetti squash to their meals due to its high content of vitamins C and K. Vitamin C serves as an antioxidant, enhancing the immune system and supporting memory retention as you age. On the other hand, vitamin K plays a crucial role in blood clotting and wound healing.
Supports Digestive Health
Spaghetti squash is a great source of fiber, providing 2.2 grams per cup, which is 9% of the daily fiber requirement. This aids in maintaining healthy digestion and regularity. Josh Schlottman, a certified personal trainer and nutritionist, recommends incorporating squash into daily meals. "It can be added to salads, soups, or roasted alongside other vegetables," Schlottman advises.
Enhances Blood Pressure Regulation
Studies indicate that winter squash is abundant in potassium, which helps offset the negative effects of sodium on blood pressure. Experts also believe this nutrient may assist in managing cholesterol levels.
Enhances Bone Health
Spaghetti squash is rich in calcium, making it an excellent choice for building and maintaining strong bones. It also contains manganese, which supports bone formation, and vitamin C, which promotes collagen production—essential for bone structure. Together, these nutrients help improve bone density and lower the risk of conditions such as osteoporosis.
Promotes Vision Health
The high beta-carotene content in spaghetti squash, which the body converts to vitamin A, supports healthy vision and prevents night blindness. Additionally, antioxidants like lutein and zeaxanthin protect the eyes from oxidative stress and UV damage. Vitamin C in spaghetti squash further reduces the risk of eye disorders, including cataracts and age-related macular degeneration.
Provides Hydration
With over 90% water content, spaghetti squash is incredibly hydrating. This makes it an excellent vegetable to help meet your daily fluid needs, which are essential for maintaining vital bodily functions such as regulating body temperature and keeping joints lubricated.
Enhances Metabolism
Vegetables are well-known for their metabolism-boosting properties, and spaghetti squash is no different. Its high levels of B vitamins, particularly vitamin B6, assist in converting food into energy, supporting the metabolism of carbs, fats, and proteins. Additionally, the fiber in spaghetti squash helps stabilize blood sugar levels, ensuring a consistent energy supply.
Offers a Low-Calorie Side Option
Spaghetti squash is an ideal low-calorie side dish, with just 31.3 calories per cup. Despite its low calorie count, it is rich in healthy carbs, protein, fiber, and other nutrients that provide a feeling of fullness without the heaviness or sluggishness often associated with high-calorie foods.
Lowers the Risk of Chronic Illnesses
The antioxidant properties of spaghetti squash make it effective in reducing the risk of chronic diseases. Nutrients like beta-carotene and vitamin C combat oxidative stress and inflammation, while fiber aids in lowering cholesterol and stabilizing blood sugar. Potassium further supports healthy blood pressure, collectively helping to prevent inflammation-related conditions such as heart disease, diabetes, and certain cancers.
Spaghetti Squash Recipe Ideas
Varner recommends slicing the squash lengthwise and removing the seeds. Brush the inside with olive oil, place it cut-side down on a baking sheet, and poke a few holes in the top. Roast at 400°F for 30 to 40 minutes until lightly browned. After cooling, use a fork to extract the strands from the squash.
"Once cooked, spaghetti squash separates into noodle-like strands," Varner notes. "It can be enjoyed plain with olive oil and seasonings, or topped with pasta sauce like traditional spaghetti." Spaghetti squash is versatile and can be customized with your favorite toppings. Explore the following recipe ideas for inspiration.
Spaghetti Squash Ragù

This comforting slow-cooker ragù features classic ingredients like ground beef, crushed tomatoes, and oregano, but instead of pairing it with pasta, it’s served over spaghetti squash. The convenience? Both the squash and ragù can cook simultaneously in the slow cooker, minimizing prep time and making cleanup a breeze.
Spaghetti Squash Parmesan

This vegetarian dish uses spaghetti squash as a pasta substitute, topped with marinara sauce, ricotta, mozzarella, grated Parmesan, and crispy panko breadcrumbs. For an eco-friendly twist, the hollowed squash serves as a natural bowl, making cleanup easier.
Instant Pot Spaghetti Squash

For a hassle-free meal, cook spaghetti squash in an Instant Pot. This hands-off method takes around 20 minutes, yielding a perfectly tender squash ready to be paired with your preferred sauce, such as homemade pesto or Trader Joe's Truffle Picante Spicy Pasta Sauce.
