Why Spaghetti Squash is Your New Favorite “Noodle”
Spaghetti squash has earned its place as a superstar in the world of healthy eating, and for good reason. Unlike grain-based pasta, spaghetti squash is a vegetable, boasting a fraction of the carbohydrates and calories while being rich in vitamins C and B6, and manganese. Its unique ability to separate into delicate, spaghetti-like strands when cooked makes it an excellent, naturally gluten-free substitute for traditional pasta. It has a mild, slightly sweet flavor that readily absorbs the delicious sauces and seasonings it’s paired with, making it the perfect canvas for a robust marinara and savory turkey meatballs.
- Low-Carb & Low-Calorie: Significantly fewer carbs and calories than wheat pasta.
- Nutrient-Dense: Packed with vitamins and minerals, including fiber for digestive health.
- Naturally Gluten-Free: A fantastic option for those with gluten sensitivities or celiac disease.
- Versatile: A mild flavor that pairs well with a variety of sauces and ingredients.
The Perfect Harmony of Flavors: Components of This Dish
The magic of Spaghetti Squash with Marinara and Turkey Meatballs lies in the synergy of its three main components, each contributing its unique texture and flavor profile to create a balanced and incredibly satisfying meal.

The Roasted Spaghetti Squash
Our foundation for this meal is perfectly roasted spaghetti squash. Roasting brings out its natural sweetness and ensures the strands are tender yet firm enough to hold up to the hearty sauce. It’s a simple process that yields incredible results, transforming a humble gourd into elegant “noodles.”
The Lean Turkey Meatballs
These aren’t just any meatballs; they’re lean, flavorful turkey meatballs that are both juicy and packed with aromatic herbs and spices. Using ground turkey reduces the fat content without sacrificing flavor, especially when seasoned correctly and cooked with care. They provide a vital protein boost and a delightful texture contrast to the soft squash.
The Vibrant Marinara Sauce
A great marinara sauce is the heart of any Italian-inspired dish. For this recipe, we’re aiming for a homemade marinara that’s rich, tangy, and bursting with the fresh flavors of ripe tomatoes, garlic, and basil. While a high-quality store-bought marinara can certainly work in a pinch, making your own allows you to control the ingredients and achieve a depth of flavor that’s truly unparalleled.

- 1/4 cup finely grated Parmesan cheese, plus more for serving
- 1/4 cup finely chopped fresh parsley
- 2 cloves garlic, minced
- 1 large egg
- 1 teaspoon dried oregano
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons olive oil, for cooking
For the Simple Marinara Sauce:
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1 (28 ounce) can crushed tomatoes
- 1 (15 ounce) can tomato sauce
- 1/2 cup water or vegetable broth
- 2 tablespoons fresh basil, chopped, plus more for garnish
- 1 teaspoon dried oregano
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste
- Pinch of red pepper flakes (optional, for a little heat)
Equipment
- Large baking sheet
- Large mixing bowl
- Large skillet or Dutch oven
- Spatula or wooden spoon
- Tongs
Instructions
Step 1: Roast the Spaghetti Squash
- Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
- Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds and stringy bits with a spoon.
- Brush the cut sides of the squash with olive oil and season generously with salt and pepper.
- Place the squash halves cut-side down on the prepared baking sheet.
- Roast for 40-60 minutes, or until the skin is easily pierced with a fork and the flesh is tender. Cooking time can vary based on squash size.
- Once cooked, remove from the oven and let cool slightly. Use a fork to scrape the flesh from the shell, creating spaghetti-like strands. Set aside.
Step 2: Prepare the Turkey Meatballs
- While the squash is roasting, prepare the meatballs. In a large mixing bowl, combine the ground turkey, panko breadcrumbs, milk, Parmesan cheese, parsley, minced garlic, egg, oregano, onion powder, salt, and pepper.
- Using clean hands, gently mix the ingredients until just combined. Be careful not to overmix, as this can lead to tough meatballs.
- Roll the mixture into 1.5-inch meatballs (you should get about 18-20 meatballs).
- Heat 2 tablespoons of olive oil in a large skillet or Dutch oven over medium-high heat.
- Add the meatballs to the hot skillet in a single layer, working in batches if necessary to avoid overcrowding. Sear the meatballs for 3-4 minutes per side, until browned all over. They don’t need to be cooked through at this stage.
- Remove the browned meatballs from the skillet and set aside.
Step 3: Simmer the Marinara Sauce
- In the same skillet (no need to clean it, the leftover bits add flavor), reduce the heat to medium. Add 2 tablespoons of olive oil if the pan is dry.
- Add the minced garlic and cook for about 30 seconds until fragrant, being careful not to burn it.
- Pour in the crushed tomatoes, tomato sauce, and water or vegetable broth. Stir in the chopped fresh basil, dried oregano, salt, pepper, and optional red pepper flakes.
- Bring the sauce to a gentle simmer, then carefully add the browned turkey meatballs back into the sauce.
- Reduce the heat to low, cover, and let the sauce and meatballs simmer for at least 20-30 minutes, or longer for deeper flavor, until the meatballs are cooked through and tender. Stir occasionally to prevent sticking.
Step 4: Assemble and Serve
- To serve, divide the spaghetti squash strands among plates.
- Ladle a generous portion of marinara sauce with several turkey meatballs over the spaghetti squash.
- Garnish with extra fresh basil and a sprinkle of grated Parmesan cheese.
- Serve immediately and enjoy your healthy and delicious Spaghetti Squash with Marinara and Turkey Meatballs!
Chef’s Secrets for Success
Perfectly Roasted Squash
- Cut Crosswise: For longer “noodles,” cut the squash into rings instead of lengthwise halves. This allows you to scrape out truly long strands.
- Don’t Overcook: Overcooked squash can become watery and mushy. It should be tender but still have a slight al dente bite.
- Season Generously: A little salt and pepper go a long way in enhancing the squash’s natural flavor.
Moist & Flavorful Meatballs
- Don’t Overmix: This is crucial for tender meatballs. Mix only until the ingredients are just combined.
- Use a Panade: The breadcrumbs soaked in milk (a “panade”) are key to keeping turkey meatballs moist, as turkey is leaner than beef.
- Sear First: Browning the meatballs before simmering adds a layer of depth and flavor that you wouldn’t get by just simmering them.
Elevating Your Marinara
- Quality Tomatoes: Start with good quality canned crushed tomatoes. San Marzano tomatoes are often preferred for their sweetness and low acidity.
- A Pinch of Sugar: If your tomatoes are a bit acidic, a tiny pinch of sugar can balance the flavors beautifully without making the sauce sweet.
- Fresh Herbs are Best: While dried herbs are fine, fresh basil added at the end makes a significant difference in the sauce’s vibrancy.
- Slow Simmer: Allow the sauce to simmer for at least 30 minutes, or even an hour, for the flavors to meld and deepen.
