Key Ingredients
Before you start roasting and stuffing, gather these fresh, simple ingredients that pack a punch of flavor and texture:
- 1 medium spaghetti squash: Crisp exterior that roasts into tender, noodle-like strands to replace pasta.
- 2 tablespoons olive oil: Adds richness and helps achieve a golden roast on the squash and chicken.
- Salt and pepper to taste: Balances flavors and enhances the natural sweetness of squash and spinach.
- 1 pound boneless, skinless chicken breasts, diced: Provides lean protein that absorbs garlic and Parmesan notes.
- 3 cloves garlic, minced: Delivers aromatic warmth and a savory backbone to the filling.
- 4 cups fresh spinach: Adds vibrant color, mild flavor, and a boost of nutrients once wilted.
- 1/2 cup grated Parmesan cheese: Imparts sharp, nutty cheesiness that binds the filling.
- 1/2 cup ricotta cheese: Offers creamy texture and mellows the tang of Parmesan inside the squash.
- 1 teaspoon Italian seasoning: Brings herbal depth with oregano, basil, and thyme accents.
- 1/4 teaspoon red pepper flakes (optional): Provides a gentle kick for those who like mild heat.
- Fresh parsley, chopped (for garnish): Sprinkles bright color and fresh herbal notes on top.
How To Make Garlic Parmesan Stuffed Spaghetti Squash with Chicken and Spinach
These steps will guide you through roasting the squash, preparing a savory chicken-spinach filling, and baking everything together until the cheese is luxuriously melted and golden. Get your apron on and let’s turn simple ingredients into a mouthwatering feast!
1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or foil for easy cleanup.
2. Cut the squash in half lengthwise using a sharp chef’s knife, then use a spoon to scoop out the seeds and stringy fibers, creating hollow “boats.”
3. Drizzle 1 tablespoon of olive oil inside each half, season with salt and pepper, and place them cut-side down on the prepared baking sheet; roast for 30–40 minutes until the flesh is tender and easily shredded with a fork.
4. While the squash roasts, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced chicken, season with salt and pepper, and cook for 5–7 minutes until cooked through and no longer pink.
5. Stir in the minced garlic and cook for 1–2 minutes until fragrant, then add the fresh spinach and cook 2–3 minutes until wilted.
6. In a mixing bowl, combine the chicken-spinach mixture with Parmesan, ricotta, Italian seasoning, and red pepper flakes; mix until evenly coated.
7. Once the squash is tender, flip the halves cut-side up and use a fork to shred the flesh into spaghetti-like strands.
8. Spoon the cheese and chicken mixture into each squash half, packing it generously.
9. Return the stuffed squash to the oven and bake for 10–15 minutes until the filling is heated through and the cheese is melted and bubbly.
10. Remove from the oven, let cool slightly, garnish with fresh parsley, and serve immediately.

Frequently Asked Questions
Here are answers to common questions about mastering this dish:
- How do I know when the spaghetti squash is cooked through and ready to be shredded?
Roast the squash cut-side down at 400°F for 30–40 minutes. It’s done when the flesh is tender enough to pierce easily with a fork and the strands pull away smoothly. If it still resists, roast for an additional 5–10 minutes and test again.
- Can I prepare any parts of this recipe ahead of time?
Yes. You can roast and shred the spaghetti squash up to a day in advance and store it covered in the refrigerator. You can also cook the chicken-spinach filling, cool it completely, and refrigerate in an airtight container. When ready to serve, reheat the squash and filling briefly, stuff, and bake for 10–15 minutes.
- What are some good substitutions or additions to the filling?
For extra flavor, you can stir in sautéed bell peppers, mushrooms, or sun-dried tomatoes. If you prefer a different cheese profile, swap the ricotta for cottage cheese or use shredded mozzarella in place of some Parmesan. Fresh herbs like basil or oregano also complement the Italian seasoning.
- How should I store and reheat leftover stuffed spaghetti squash?
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place a portion in an oven-safe dish, cover with foil, and warm at 350°F for 10–12 minutes until heated through. You can also microwave on medium power for 2–3 minutes, stirring halfway.
- My filling seems dry. How can I keep it moist and cheesy?
Ensure you mix the ricotta and Parmesan thoroughly with the chicken and spinach. If it still seems dry, stir in 1–2 tablespoons of reserved pan juices or a splash of chicken broth. You can also drizzle a little olive oil over the filling before the final bake.
- How can I adjust the spice level?
The recipe calls for ¼ teaspoon of red pepper flakes for mild heat. To increase the kick, add up to ½ teaspoon or sprinkle chili powder into the chicken while cooking. For a milder dish, omit the red pepper flakes entirely.
- Is this recipe suitable for meal prep?
Absolutely. Roast and shred the squash, cook the filling, and store separately. In meal-prep containers, layer squash and filling, then refrigerate. When you’re ready to eat, simply reheat in the microwave or oven until warm and the cheese is melted.

Instructions
-
Preheat your oven to 400°F (200°C).
-
Carefully cut the spaghetti squash in half lengthwise using a sharp knife. Scoop out the seeds and stringy insides with a spoon.
-
Drizzle 1 tablespoon of olive oil inside each half of the squash and season with salt and pepper. Place the squash cut-side down on a baking sheet and roast in the preheated oven for about 30-40 minutes, or until the flesh is tender and can be easily shredded with a fork.
-
While the squash is roasting, heat the remaining tablespoon of olive oil in a large skillet over medium heat. Add the diced chicken and season with salt and pepper. Cook for about 5-7 minutes, or until the chicken is cooked through and no longer pink in the center.

Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant. Then, add the fresh spinach and cook until wilted, about 2-3 minutes.
-
In a mixing bowl, combine the cooked chicken and spinach mixture with the Parmesan cheese, ricotta cheese, Italian seasoning, and red pepper flakes (if using). Mix well to combine all ingredients.

Once the spaghetti squash is done roasting, carefully flip the halves over so the cut side is facing up. Use a fork to scrape and fluff the squash, creating "spaghetti" strands.

Spoon the chicken and spinach mixture into each half of the prepared spaghetti squash, mounding it generously.
-
Return the stuffed squash to the oven and bake for an additional 10-15 minutes, until heated through and the cheese is melted.
