🧡 The Secret Behind Its Flavor
At the heart of this recipe is the combination of roasted spaghetti squash and creamy garlic chicken sauce. When roasted, spaghetti squash transforms into golden, noodle-like strands that absorb the sauce beautifully. The chicken provides protein and substance, while the creamy base of Greek yogurt, cream cheese, and Parmesan gives the dish its luscious texture.
Fresh spinach adds color and nutrients, while garlic, thyme, and red pepper flakes build layers of warmth and depth. It’s the perfect balance of creamy, garlicky, and savory — the kind of meal that makes your kitchen smell like heaven.
🍽️ Ingredients You’ll Need
Here’s everything you’ll need to make the perfect Creamy Chicken Spaghetti Squash:
For the Squash:
- 1 medium spaghetti squash (about 2–3 pounds)
- 1 tablespoon olive oil
- Salt and black pepper, to taste
- ½ teaspoon garlic powder
For the Chicken & Sauce:
- 2 boneless, skinless chicken breasts, diced into small cubes
- 2 tablespoons butter
- 1 small yellow onion, finely chopped
- 3 cloves garlic, minced
- 2 cups fresh spinach leaves
- ¾ cup low-sodium chicken broth
- 4 ounces cream cheese, softened
- ½ cup Greek yogurt (for light tanginess)
- ½ cup freshly grated Parmesan cheese
- ½ teaspoon dried thyme
- ¼ teaspoon red pepper flakes (optional for mild heat)
- 2 tablespoons fresh parsley, chopped (for garnish)
🔥 Step-by-Step Instructions
Step 1: Roast the Spaghetti Squash
Preheat your oven to 400°F (200°C). Slice the spaghetti squash lengthwise, scoop out the seeds, and brush the insides with olive oil. Season with salt, pepper, and garlic powder.
Place cut-side down on a baking sheet lined with parchment paper. Roast for 30–35 minutes, or until the flesh is tender and can easily be scraped into spaghetti-like strands with a fork.
Let it cool slightly, then use a fork to pull apart the strands — this is your healthy “pasta base.”
Step 2: Cook the Chicken
While the squash is roasting, heat butter in a large skillet over medium heat. Add the diced chicken and cook until golden brown on all sides. Season lightly with salt and pepper.
Once cooked through, remove the chicken from the pan and set aside.
Step 3: Build the Flavor Base
In the same pan, add the chopped onion and sauté until soft and translucent — about 3 minutes. Add minced garlic and cook for another 30 seconds until fragrant.
Add spinach leaves and sauté just until wilted — this keeps them bright green and tender.
Step 4: Create the Creamy Sauce
Pour chicken broth into the skillet and bring to a gentle simmer. Stir in cream cheese and Greek yogurt, mixing until the sauce becomes smooth and creamy.
Next, add Parmesan, thyme, and red pepper flakes. Stir constantly to avoid curdling. The sauce should become thick and silky — rich but not heavy.
Step 5: Combine and Layer
Return the cooked chicken to the pan and toss it in the sauce until coated. Let it simmer for a few minutes so the flavors meld beautifully.
Take your roasted spaghetti squash strands and mix a portion of the sauce directly into them for even flavor. Then fill each squash half with the creamy chicken mixture and top with a sprinkle of Parmesan.
Step 6: Bake and Serve
Place the filled squash halves back into the oven and bake for 10–15 minutes, until the top becomes bubbly and slightly golden.
Let it rest for 5 minutes before serving. Garnish with chopped parsley — and if you like, a little squeeze of lemon to balance the richness.
🍋 Chef’s Pro Tips
- Roast cut-side down for the most tender, caramelized strands.
- Don’t overcook the spinach — wilt it lightly for better color.
- Use freshly grated Parmesan, not pre-shredded, for smooth melting.
- Mix a bit of sauce into the squash strands before stuffing for deeper flavor.
- Add a dash of nutmeg for subtle warmth in the sauce.
- Use leftover roasted chicken to save time.
🌿 Variations to Try

🍷 What to Serve It With
- Garlic bread or whole-grain toast

It’s also filling enough to be a complete meal on its own.
🧊 Storage & Reheating
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Warm gently in the oven or microwave with a splash of broth to restore creaminess.
- Avoid freezing: The sauce may separate after thawing, affecting texture.
