Transforming tender strands of spaghetti squash into a luxurious bed for creamy Tuscan chicken creates an incredible low-carb twist on classic Alfredo. This dish marries the subtle sweetness of roasted spaghetti squash with a velvety sauce enriched by sun-dried tomatoes, fresh spinach, and perfectly seasoned chicken.
In my kitchen, this recipe has become a regular feature during fall squash season. The way the sauce clings to each golden strand of spaghetti squash creates such a satisfying alternative to traditional pasta.
Essential Ingredients Guide
- Spaghetti squash: Brings a subtle sweetness and creates those distinctive pasta-like strands. Look for one that feels heavy for its size and has a firm, cream-colored shell
- Heavy cream: Forms the foundation of our silky sauce. Choose fresh cream with a high fat content for the smoothest results
- Sun-dried tomatoes: Add concentrated bursts of flavor. Select oil-packed varieties for the richest taste
- Parmesan cheese: Should be freshly grated from a block to ensure proper melting and authentic flavor
- Fresh spinach: Wilts beautifully into the sauce. Choose bright, crisp leaves without any yellowing
Creating Your Masterpiece
- Preparing the Squash:
- Cut your squash lengthwise and remove the seeds. Rub the flesh generously with olive oil and season well with salt and pepper. Place cut-side down on a baking sheet and roast until the strands separate easily with a fork.
- Developing the Flavors:
- Start by seasoning your chicken thoroughly with Italian herbs and spices. Sear until golden brown and cooked through, allowing a beautiful crust to form. Set aside to rest before cutting.
- Creating the Sauce:
- Sauté your aromatics until fragrant and softened. Pour in the cream slowly, stirring constantly as it begins to thicken. Add cheese gradually to achieve a smooth, velvety consistency.
- Final Assembly:
- Fold in your perfectly cooked chicken and tender squash strands. Stir gently until every component is enrobed in the luxurious sauce.

My family particularly loves the sun-dried tomatoes in this dish. Their intense flavor reminds us of summers in Italy, and they add such a wonderful depth to the creamy sauce.
Perfect Pairings
Transform this dish into a complete feast by serving it alongside a crisp arugula salad dressed with lemon vinaigrette. A glass of chilled Pinot Grigio complements the creamy sauce beautifully.
Customizing Your Creation
- Consider swapping spinach for Tuscan kale, or adding sautéed mushrooms for an earthier flavor profile
- For dairy-sensitive guests, coconut cream can create a similarly rich sauce
Keeping Your Leftovers Fresh
Store any remaining portions in an airtight container, keeping the sauce separate from the squash strands when possible. Reheat gently on the stovetop, adding a splash of cream to restore the sauce's silky texture.

After years of making this dish, I've found it brings together the comfort of classic Alfredo with the lightness of fresh vegetables in a way that satisfies both traditional pasta lovers and those seeking healthier alternatives.
Frequently Asked Questions
- → How do I know when the spaghetti squash is done?
- The squash is done when you can easily pierce it with a fork and the flesh easily separates into spaghetti-like strands, usually after 45-50 minutes at 400°F.
- → Can I make this dish ahead of time?
- Yes, you can prepare this dish up to 2 days ahead. Store in an airtight container in the refrigerator and reheat gently on the stovetop or microwave.
- → What can I substitute for heavy cream?
- While heavy cream provides the best texture, you can use half-and-half or whole milk mixed with a bit of cornstarch for a lighter version.
- → Why is my sauce too thin?
- If your sauce is thin, let it simmer longer to reduce, or add more parmesan cheese. The cheese will help thicken the sauce as it melts.
- → Can I freeze this dish?
- While possible, freezing isn't recommended as the cream sauce may separate and the squash can become watery when thawed. Best enjoyed fresh or within 2-3 days when refrigerated.
