This easy one-pan Tuscan Chicken and Spaghetti Squash recipe is a perfect, healthy dinner. It delivers rich, comforting flavors without the heaviness of traditional pasta. Spaghetti squash, a fantastic low-carb vegetable, transforms into tender, spaghetti-like strands that soak up a creamy garlic and sun-dried tomato sauce. This dish is a crowd-pleaser for both weeknight meals and special occasions.

Why Spaghetti Squash is a Kitchen Superstar
Beyond its delightful texture, spaghetti squash is a nutritional powerhouse. It’s low in calories and carbohydrates compared to pasta, making it a favorite for those monitoring their carb intake. The strands are high in fiber, which aids digestion and promotes a feeling of fullness.
Replacing traditional pasta with this vegetable is a simple swap for adding more vitamins and minerals to your meal.
Spaghetti squash is also incredibly versatile. It can be baked, roasted, or even microwaved for a quick prep, as this recipe demonstrates. Its neutral flavor makes it the perfect canvas for bold sauces, from savory tomato-based sauces to rich, creamy ones like in this Tuscan preparation.
How to Pick and Store Your Squash
For the best results, choose a spaghetti squash that feels firm and heavy for its size. The skin should be a pale, even yellow without any soft spots or cracks, which can indicate spoilage.
A whole squash can be stored in a cool, dry place for several weeks. Once cooked, the flesh should be stored in an airtight container in the refrigerator and used within 3-5 days.
Gathering Your Ingredients
The magic of this recipe lies in its simple, fresh ingredients. We use savory seasonings, aromatic vegetables, and a rich sauce to create a dish bursting with flavor.
For the Squash: You’ll need one medium spaghetti squash.
For the Chicken: Use one pound of boneless, skinless chicken breasts or thighs, cut into bite-sized pieces. Season generously with salt, pepper, and Italian seasoning.
For the Aromatic Base: Four cloves of minced garlic and one minced shallot build the foundational flavor. We’ll use two tablespoons of julienned sun-dried tomatoes (from oil, patted dry) for a sweet, concentrated burst of tomato flavor.
For the Creamy Sauce: The sauce comes together with two tablespoons of unsalted butter, one cup of heavy whipping cream, and one-third cup of freshly grated Parmesan cheese for a touch of salty, nutty flavor.
For Freshness: Three ounces of fresh baby spinach will be stirred in at the end to wilt gently. Fresh parsley makes a beautiful, optional garnish.
How to Make Tuscan Chicken with Spaghetti Squash
Follow these simple steps for a perfectly cooked, flavorful meal all made in one pan (plus the microwave for the squash). It’s a fantastic method for a stress-free dinner.
Step 1: Cook the Spaghetti Squash
Start by carefully piercing the spaghetti squash all over with the tip of a sharp knife. This is a crucial safety step to allow steam to escape. Place it on a microwave-safe plate and microwave on high for 8-12 minutes. The squash is done when the skin yields easily to pressure.
Let it cool on the counter for a few minutes while you cook the chicken. Once cool enough to handle, slice it in half lengthwise, scoop out the seeds, and use a fork to scrape the flesh into beautiful, long strands.
Step 2: Sear the Chicken
While the squash cools, season your chicken pieces. Heat one tablespoon of the butter in a large, deep skillet over medium-high heat. Add the chicken in a single layer and cook, stirring occasionally, for about 7 minutes or until the pieces are cooked through and no longer pink in the center.
Transfer the cooked chicken to a clean plate and cover lightly with foil to keep warm.
Step 3: Create the Creamy Tuscan Sauce
In the same skillet, melt the remaining tablespoon of butter. Add the minced garlic and shallot, cooking for just 1-2 minutes until fragrant and slightly softened. Be careful not to let them brown. Stir in the sun-dried tomatoes and cook for another minute to warm them through. Pour in the heavy cream, bring the mixture to a gentle bubble, and let it simmer for a minute or two until slightly thickened.
Turn off the heat. Stir in the grated Parmesan cheese until melted and smooth, then fold in the fresh baby spinach. It will wilt from the heat of the sauce in just seconds. Finally, add the cooked chicken and any juices from the plate back into the skillet, stirring to coat everything in the sauce.
Step 4: Combine and Serve
Add the scraped spaghetti squash strands directly into the skillet with the creamy chicken sauce. Gently toss everything together until the squash is evenly coated. Taste and adjust seasoning with a pinch more salt or pepper if needed. Garnish with fresh chopped parsley for a pop of color and freshness. Serve immediately while hot.
