Ingredients You’ll Need
For the Spaghetti Squash:
- 1 medium spaghetti squash (about 3 pounds)
- 1 tablespoon olive oil
- Salt and pepper to taste
For the Chicken Alfredo Sauce:
- 2 cups cooked chicken, shredded (you can use rotisserie chicken for convenience)
- 1 cup heavy cream
- 1 cup grated Parmesan cheese
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
For Topping:
- 1 cup mozzarella cheese, shredded
- Fresh parsley, chopped (for garnish)
Ingredient Notes:
- Choose a firm, vibrant spaghetti squash for the best flavor and texture.
- For a lighter take, you can substitute the heavy cream with half-and-half or a dairy-free cream alternative.
- Freshly shredded cheese melts better than pre-shredded versions, which often contain anti-caking agents.
How to Prepare This Recipe
- Preheat Your Oven: Begin by preheating your oven to 400°F (200°C). This will ensure that your spaghetti squash roasts perfectly.
- Prepare the Spaghetti Squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the insides with olive oil and season with salt and pepper. Place cut-side down on a baking sheet lined with parchment paper.
- Roast the Squash: Roast the spaghetti squash in the preheated oven for about 30-40 minutes, or until the flesh is fork-tender. Keep an eye on it towards the end you want it to be soft but not mushy.
- Make the Alfredo Sauce: While the squash is roasting, prepare the sauce. In a skillet over medium heat, add minced garlic and sauté for about a minute until fragrant. Pour in the heavy cream, stirring gently.
- Add Cheese and Seasoning: Gradually whisk in the grated Parmesan cheese until melted and creamy. Add the shredded chicken and Italian seasoning, then season with salt and pepper to taste. Stir until everything is well combined and heated through.
- Combine Everything: Once the spaghetti squash is ready, use a fork to scrape out the strands into a large bowl. Combine the squash strands with the creamy chicken Alfredo sauce, mixing well to ensure each strand is coated.
- Top with Mozzarella: Transfer the mixture back into the squash halves or into a baking dish. Sprinkle the top with shredded mozzarella cheese.
- Final Bake: Return it to the oven and bake for an additional 10-15 minutes or until the cheese is bubbling and golden brown.
- Garnish and Serve: Remove from the oven, garnish with fresh parsley, and let it cool for a few minutes before serving.
Tips & Recipe Variations
- Use Fresh Herbs: Incorporating fresh basil or oregano into the sauce can add a delightful burst of flavor.
- Make it Vegetarian: Swap the chicken for sautéed mushrooms or a variety of seasonal vegetables for a hearty vegetarian version.
- Low-Carb Option: This recipe is naturally low in carbs due to the spaghetti squash, making it perfect for low-carb diets.
- Storage: If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave until warmed through.
- Freezing: You can freeze the Baked Chicken Alfredo Spaghetti Squash in individual portions for convenient meals later.
How to Enjoy This Dish
This Baked Chicken Alfredo Spaghetti Squash is versatile when it comes to serving suggestions. For a complete meal, pair it with a crisp side salad topped with a light vinaigrette. Garlic bread is another delightful side that complements the creamy alfredo perfectly. For beverage pairings, consider a chilled glass of white wine to elevate the dining experience or sparkling water with a slice of lemon for a refreshing contrast.
When serving, I recommend plating the spaghetti squash halves as they are for a rustic presentation, garnishing generously with parsley for that pop of color.
Common Questions
Can I make this recipe ahead of time?
Yes, you can prepare the sauce and roast the squash in advance. Keep them separate in the refrigerator and combine when ready to bake.
Can I freeze the leftovers?

What can I use instead of chicken?
Shredded tofu or a medley of hearty vegetables, such as zucchini and bell peppers, make excellent substitutes.
