Step‑by‑Step Instructions for Chicken Parmesan Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (232°C). This high temperature ensures that your Chicken Parmesan Spaghetti Squash will bake quickly, resulting in a crispy coating for the chicken. While the oven is heating, prepare your baking sheet by lightly greasing it with cooking spray or a bit of butter, setting the stage for delightful, non-stick baking.
Step 2: Prepare the Herb Mixture
In a medium mixing bowl, combine grated Parmesan cheese, dried oregano, and dried basil, along with a pinch of salt and pepper to taste. Mix these ingredients thoroughly until they are well incorporated. This flavorful blend will create a delicious crust for your chicken, so you want every piece coated evenly with the aromatic herbs and cheese.
Step 3: Season the Chicken
Take your boneless skinless chicken breasts, and gently pound them to an even thickness, ensuring they cook uniformly. Brush each piece with melted butter, then sprinkle with salt and pepper to enhance their flavor. This step prepares your chicken breasts for the cheese coating, setting the stage for a juicy and flavorful Chicken Parmesan.
Step 4: Coat the Chicken
Carefully take each seasoned chicken breast and dip it into the herb and cheese mixture, pressing gently to ensure an even coating sticks to the chicken. Place each coated piece on the greased baking sheet, keeping a little space between them. This step is crucial for achieving that gorgeous, crispy texture in the baked Chicken Parmesan Spaghetti Squash.
Step 5: Bake the Chicken
Slide the baking sheet into your preheated oven and bake for 20 minutes. After that, flip the chicken breasts over and continue baking for an additional 5 minutes. You’ll know they’re done when they’re golden brown on the outside and have reached an internal temperature of 165°F (74°C), ensuring juicy chicken underneath the crispy crust.
Step 6: Add Sauce and Cheese
Once the chicken is perfectly baked, remove the baking sheet from the oven. Spoon marinara sauce generously over each piece of chicken, followed by a handful of part-skim mozzarella cheese. This layering of sauce and cheese adds moisture and richness, making your Chicken Parmesan Spaghetti Squash not only flavorful but also visually appealing.
Step 7: Melt the Cheese
Return the baking sheet to the oven, allowing the chicken to bake for an additional 5-7 minutes, or until the mozzarella is melted and bubbling. Keep an eye on the cheese; it should be ooey-gooey and slightly golden but not burnt. This step wraps your Chicken Parmesan in a deliciously creamy layer of melted cheese, enhancing the overall dish.
Step 8: Prepare the Spaghetti Squash
While your chicken is baking, prepare the spaghetti squash. Halve it lengthwise and scoop out the seeds. Drizzle with olive oil, season with salt and pepper, and roast in the oven for about 30–40 minutes, cut side down, until tender. Once done, scrape with a fork to create spaghetti-like strands that serve as the perfect low-carb base for your Chicken Parmesan.
Step 9: Serve the Dish
Finally, once the Chicken Parmesan and spaghetti squash have finished their respective cooking processes, plate them beautifully. Serve the juicy, cheesy chicken atop the strands of spaghetti squash, allowing the savory marinara sauce to drizzle over. This presentation not only looks stunning but also epitomizes the indulgent yet healthy concept of Chicken Parmesan Spaghetti Squash.

Expert Tips for Chicken Parmesan Spaghetti Squash
• Pounding Technique: Ensure your chicken breasts are pounded evenly to achieve uniform cooking. This prevents some parts from drying out while others remain undercooked.
• Temperature Check: Use a meat thermometer to check that the chicken reaches an internal temperature of 165°F (74°C). This guarantees juicy chicken underneath the crispy coating.
• Casserole Style: For a cozy casserole version, layer cooked spaghetti squash, chicken, marinara sauce, and mozzarella in a baking dish before final baking.
• Cheese Choice: Opt for part skim mozzarella for a lighter option, but full-fat is a delicious alternative if you’re feeling indulgent.
• Alternative Sauces: Feel free to swap marinara for a homemade or store-bought alfredo sauce for a creamy twist; just keep an eye on overall calories.
• Flavor Boost: Experiment with fresh herbs in the coating. Using fresh basil instead of dried basil can elevate the flavors in your Chicken Parmesan Spaghetti Squash.

Chicken Parmesan Spaghetti Squash Recipe FAQs
How do I choose the right spaghetti squash?
Look for a spaghetti squash that is firm, with a smooth, golden skin. Avoid squash with soft spots or dark blemishes, as these can indicate overripeness. The size doesn’t matter much, but a medium-sized squash (about 3-5 pounds) will yield the best amount of “noodles”.
How should I store leftovers of Chicken Parmesan Spaghetti Squash?
Store your leftovers in an airtight container in the refrigerator for up to 3 days. To maintain the texture and flavor, I recommend separating the chicken from the spaghetti squash if possible. This way, you can rehear them separately and keep the crispiness of the chicken intact.
Can I freeze Chicken Parmesan Spaghetti Squash?
Absolutely! For longer storage, wrap individual portions of the Chicken Parmesan tightly in plastic wrap or foil and place them in a freezer bag. This dish can be frozen for up to 2 months. When you’re ready to enjoy, thaw it in the refrigerator overnight and bake at 350°F (175°C) for 15-20 minutes for a perfect reheating.
What if my chicken doesn’t cook evenly?
If you notice that the chicken isn’t cooking evenly, make sure you pound the chicken breasts to an even thickness before baking—they cook more uniformly that way. Additionally, using a meat thermometer to check that the internal temperature reaches 165°F (74°C) will provide additional assurance that your chicken is cooked through.
Can I make this recipe gluten-free?
Yes! This Chicken Parmesan Spaghetti Squash is naturally gluten-free as it uses no breadcrumbs. However, always ensure that your marinara sauce is gluten-free if you’re using store-bought varieties. Check for certification or labels that confirm they are gluten-free.
Is this dish safe for my pets?
While chickens and certain vegetables are safe for pets in moderation, avoid giving them marinara sauce, especially if it contains garlic or onions, as these can be harmful to pets. Always check ingredients before sharing human food with your furry friends.
