How to Make Chicken Parmesan Stuffed Spaghetti Squash Recipe
Step 1: Roast the Spaghetti Squash
Start by preheating your oven to 400°F. Carefully slice each spaghetti squash in half lengthwise, then scoop out the seeds—this can be a fun task that sets the foundation for your meal. Brush the inside of each half with olive oil and season with salt and black pepper. Place the halves cut-side down on a baking sheet; this method steams and roasts the squash simultaneously, resulting in tender flesh that separates into perfect strands. Roast for 30 to 40 minutes until the squash is soft and you can easily scrape the flesh with a fork.
Step 2: Prepare the Chicken Mixture
While your squash is roasting, mix together shredded chicken, marinara sauce, Italian seasoning, and garlic powder in a bowl. This blend absorbs the classic chicken Parmesan flavors, making it juicy and packed with warmth from the herbs. Using rotisserie chicken can save you time and add extra savoriness, but freshly cooked chicken works beautifully too.
Step 3: Combine and Fill the Squash
Once the squash halves are tender, take them out of the oven and gently use a fork to loosen the strands inside, keeping them contained within the shell. This stringy texture is what makes this dish so fun and unique. Divide the chicken mixture evenly and fold it gently into the squash strands, ensuring every bite will have that perfect balance of flavors and textures.
Step 4: Add Cheese and Optional Topping
Top each stuffed squash half with shredded mozzarella and grated Parmesan cheese. For those who love a little crunch, sprinkle with panko breadcrumbs and lightly spray with olive oil to help them brown during baking. This step brings the luscious, bubbly, golden finish that makes chicken parmesan irresistible.
Step 5: Bake and Broil to Perfection
Return the stuffed squash halves to the oven and bake for another 10 to 15 minutes, until the cheese has melted and the topping is hot and bubbly. If you want an extra golden, crispy top, switch your oven to broil for 2 to 3 minutes—just keep a close eye to avoid burning. Garnish with chopped fresh basil or parsley for a fresh pop of color and flavor before serving.
How to Serve Chicken Parmesan Stuffed Spaghetti Squash Recipe

Garnishes
Fresh herbs like basil or parsley are perfect to finish off this dish. Not only do they add a vibrant green contrast, but they also provide an aromatic lift that complements the cheesy, savory filling. For an extra treat, drizzle a little more marinara on top or sprinkle crushed red pepper flakes for some heat.
Side Dishes
Because this Chicken Parmesan Stuffed Spaghetti Squash Recipe is so hearty, lighter side dishes pair best. A crisp green salad tossed in a tangy vinaigrette, steamed or roasted veggies like asparagus or broccoli, or even a simple garlic bread can round out the meal without overshadowing the main event.
Creative Ways to Present
For a fun family meal or dinner party, serve the squash halves right on their shells—it’s rustic and inviting. You can also scoop the filling into individual ramekins for a charming presentation or mix the stuffing ahead of time and top it in muffin tins for cute, single-serve bites everyone will love. This recipe adapts beautifully to your style and occasion.
Make Ahead and Storage
Storing Leftovers
Leftovers keep well in an airtight container in the refrigerator for up to 3 days. Let the dish cool completely before storing to maintain the cheese’s texture and prevent sogginess. Reheat gently to preserve the squash’s tender strands and the fresh flavors of the chicken parmesan filling.
Freezing
You can freeze leftover portions wrapped tightly in foil and stored in a freezer-safe bag for up to 2 months. Thaw the squash in the refrigerator overnight before reheating for best results. Keep in mind the texture might be slightly softer after freezing, but the flavors remain deliciously intact.
Reheating
To reheat, place the stuffed squash halves in a preheated oven at 350°F for about 15 minutes or until warmed through. Avoid microwaving if possible, as this can lead to uneven heating and mushy squash. If the topping has lost some crispness, broiling for a minute or two can revive that delightful crunch.
FAQs
Can I make this Chicken Parmesan Stuffed Spaghetti Squash Recipe gluten-free?
Absolutely! Simply omit the panko breadcrumbs or substitute them with gluten-free breadcrumbs to keep the dish gluten-free without sacrificing texture.
Is it possible to use a different type of squash?
While spaghetti squash’s unique strands make it ideal for this recipe, you could experiment with other squash varieties, but the texture and presentation will differ significantly.
Can I use ground chicken instead of shredded chicken?
Yes, ground chicken can work if cooked and seasoned well, though shredded chicken provides a better texture and blends more seamlessly with the squash strands.
How do I know when the spaghetti squash is fully cooked?
When the squash strands easily separate with a fork and the flesh is tender all the way through, it’s perfectly cooked. Roasting times can vary depending on size and oven, so test with a fork after 30 minutes.
Can this recipe be made ahead of time?
You can prepare the filling and roast the squash in advance, then assemble and bake just before serving to save time on busy days.
