Step‑by‑Step Instructions for Chicken Spaghetti Squash Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is perfect for roasting the spaghetti squash, allowing it to become tender and easy to shred. While the oven heats, gather a large baking sheet lined with parchment paper, ready to cradle the squash during its roasting journey.
Step 2: Prepare the Spaghetti Squash
Slice the spaghetti squash in half lengthwise and scoop out the seeds using a spoon. Brush the insides with olive oil, then generously season with salt and pepper. Place the squash halves cut-side down on the prepared baking sheet and slide it into the preheated oven. Roast for 40-50 minutes until the flesh is tender and easily pierced with a fork.
Step 3: Mix the Creamy Filling
While the spaghetti squash roasts, grab a mixing bowl and combine cream cheese, mozzarella, Parmesan, sour cream, and minced garlic. Use a hand mixer or fork to blend until the mixture is smooth and creamy, creating a luscious filling for your Chicken Spaghetti Squash Casserole. This step ensures that every bite will be rich and flavorful.
Step 4: Stir in Chicken and Spinach
Next, fold in the thawed and squeezed spinach along with the shredded rotisserie chicken into the creamy mixture. Stir gently but thoroughly, making sure everything is well combined. The chicken will add protein while the spinach contributes essential nutrients and vibrant color, elevating your casserole to new heights.
Step 5: Shred the Squash
Once the spaghetti squash has cooled slightly, use a fork to carefully shred the flesh into long strands, resembling traditional pasta. Incorporate these strands into the chicken and cheese mixture, tossing gently until everything is evenly dispersed. This wonderful medley creates the base of your delightful Chicken Spaghetti Squash Casserole.
Step 6: Transfer to Baking Dish
Grease a medium-sized baking dish with a little olive oil and transfer the entire mixture into it, smoothing the top with a spatula for even baking. This step prepares the dish for its final transformation in the oven, making sure it’s evenly distributed for consistent cooking and a beautiful presentation.
Step 7: Bake to Perfection
Bake the casserole in the oven for 20-25 minutes, or until it becomes golden brown and bubbly. To achieve an extra crispy top, broil for an additional 2-3 minutes, keeping a watchful eye as it can quickly turn from golden to burnt. This final step will enhance the dish’s visual appeal and texture.
Step 8: Cool and Serve
Once baked, allow the Chicken Spaghetti Squash Casserole to cool for a few minutes before serving. This cooling period allows the casserole to set, making it easier to slice and serve. Enjoy every creamy, cheesy bite, knowing you’ve created a culinary delight that the whole family will love!

Chicken Spaghetti Squash Casserole Recipe FAQs
What’s the best way to select a spaghetti squash?
Absolutely! When choosing a spaghetti squash, look for one that feels heavy for its size with a hard, golden-yellow skin. Avoid any squash with soft spots or dark blemishes, as these can indicate overripeness. A fresh spaghetti squash should be firm and sound solid when tapped.
How do I store leftover Chicken Spaghetti Squash Casserole?
I often store leftovers in airtight containers in the refrigerator for up to 4 days. Make sure the casserole has cooled down completely before sealing it to maintain its freshness. When ready to enjoy, simply reheat it gently in the oven or microwave.

What if my casserole turns out too watery?
Very! A watery casserole can be frustrating, but no worries! To prevent this, be sure to squeeze out as much moisture as possible from thawed spinach and from the spaghetti squash after roasting. Also, ensure that the cheese and chicken mixture is balanced without too much liquid. If it still comes out watery, simply return it to the oven for a few more minutes to help evaporate excess moisture.
Are there any dietary substitutions I can make?
Absolutely! This recipe is quite flexible. For a dairy-free version, you can use vegan cream cheese and mozzarella alternatives.
