How To Make Garlic Parmesan Stuffed Spaghetti Squash with Chicken and Spinach
This recipe is a delightful journey from roasting squash to stuffing it with a creamy, protein-packed filling. You’ll roast the spaghetti squash until tender, sauté chicken with garlic and spinach, blend in cheeses and seasonings, then nestle everything back into the squash shells for a final bake. The result is a vibrant, flavorful dinner that’s low-carb-friendly and perfect for sharing.
1. Preheat your oven to 400°F (200°C) to ensure even roasting and melting.
2. Carefully cut the spaghetti squash in half lengthwise using a sharp knife. Scoop out the seeds and stringy insides with a spoon for clean, cavity-ready shells.
3. Drizzle 1 tablespoon of olive oil inside each half, season with salt and pepper, then place cut-side down on a baking sheet. Roast for 30–40 minutes until the flesh is tender and fork-shreddable.
4. While the squash roasts, heat the remaining tablespoon of olive oil in a large skillet over medium heat. Add diced chicken, season with salt and pepper, and cook 5–7 minutes until no longer pink.
5. Stir in minced garlic and cook 1–2 minutes until fragrant. Add fresh spinach and sauté 2–3 minutes until wilted and bright green.
6. Combine the chicken-spinach mixture in a bowl with Parmesan, ricotta, Italian seasoning, and red pepper flakes (if using). Mix thoroughly to create a creamy, well-seasoned filling.
7. Flip the roasted squash halves so cut sides face up. Use a fork to scrape and fluff the flesh into spaghetti-like strands, creating a cozy bed for the filling.
8. Spoon the cheesy chicken and spinach mixture into each squash half, mounding it generously for maximum flavor in every bite.
9. Return the stuffed squash to the oven and bake an additional 10–15 minutes until heated through and the cheese melts into golden pockets.
10. Remove from the oven, let cool briefly, then garnish with chopped parsley before serving to add a fresh, vibrant touch.
Serving Suggestions
Once your squash is bubbling and golden, it’s time to think about plating. Whether you’re serving friends, family, or meal-prep lunches, these ideas will elevate each portion and bring out the best in every bite.
- Family-style Platter: Arrange both halves on a large, warmed platter so everyone can dig in and serve themselves.
- Garnish with Extra Cheese: Sprinkle additional grated Parmesan before the final bake for a crispy, golden crust.
- Add a Side Salad: Pair with a simple green salad dressed in lemon vinaigrette to balance the richness.
- Lemon Wedges: Serve with fresh lemon wedges so guests can squeeze bright citrus over the filling for added zing.

Frequently Asked Questions
Got questions? Here are quick answers to common queries about this stuffed spaghetti squash recipe.
- How do I know when the spaghetti squash is perfectly roasted and ready to be shredded?
The squash is done when the flesh is tender and you can easily scrape it with a fork to create spaghetti-like strands. This usually takes 30–40 minutes at 400°F (200°C). If the skin yields slightly under gentle pressure, it’s a good sign that the squash is fully cooked.
- Can I prepare any components of this recipe ahead of time?
Yes. You can roast and shred the spaghetti squash a day in advance and store it in an airtight container in the refrigerator. You can also cook the chicken-spinach filling a day ahead and refrigerate it. When you’re ready to serve, simply reheat the squash and stuffing together, then bake for 10–15 minutes until warmed through and the cheese melts.
- What can I use instead of ricotta cheese if I don’t have any on hand?
You can substitute cottage cheese (drained) or mascarpone for a similar creamy texture. Greek yogurt thinned with a bit of milk also works in a pinch, but the filling may be tangier. Adjust salt and pepper to taste when using substitutes.
- How do I adapt this recipe for extra vegetables or dietary preferences?
Feel free to stir in diced bell peppers, sliced mushrooms, or sun-dried tomatoes with the chicken and spinach. For a dairy-free version, omit the Parmesan and ricotta and use a plant-based cheese alternative. You can also swap the chicken for turkey or a plant-based protein like tofu or chickpeas.
- What’s the best way to reheat leftover stuffed spaghetti squash?
Place leftovers in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 10–12 minutes or until heated through. You can also microwave individual servings for 2–3 minutes on medium power, stirring halfway to ensure even heating.
- Can I make this recipe spicier or milder?
To increase heat, add an extra pinch of red pepper flakes or a dash of hot sauce to the filling. To tone it down, omit the red pepper flakes altogether and use just the Italian seasoning for flavor without the heat.
- How long will leftovers keep, and can I freeze them?
Stored in an airtight container, leftover stuffed squash will keep in the fridge for up to 3 days. To freeze, wrap individual halves tightly in plastic wrap and place in a freezer bag for up to 2 months. Thaw overnight in the refrigerator before reheating as directed.
