Step‑by‑Step Instructions for Irresistible Chicken Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (204°C). While the oven heats, line a baking sheet with parchment paper to prevent sticking. This setup will be perfect for roasting the spaghetti squash, ensuring it becomes beautifully tender and easy to scrape into strands later.
Step 2: Prepare the Spaghetti Squash
Carefully halve the spaghetti squash lengthwise using a sharp knife. Scoop out the seeds from each half and place the squash cut-side down on the prepared baking sheet. Roast in the oven for 30-40 minutes, checking for tenderness; it should feel soft when pierced with a fork yet still hold its shape.
Step 3: Season and Cook the Chicken
While the squash is roasting, take your boneless, skinless chicken breasts and season them generously with kosher salt and pepper. Heat a large skillet over medium-high heat, then add a mixture of unsalted butter and vegetable oil. Once hot, add the chicken to the pan, searing for about 5-7 minutes on each side until golden brown.
Step 4: Finish Cooking the Chicken
When the chicken is nicely browned, reduce the heat to medium-low, cover the skillet, and cook for an additional 8-10 minutes, or until the internal temperature reaches 165°F (74°C). Once done, remove the chicken from the skillet and let it rest on a plate, covering it lightly to keep it warm.
Step 5: Create the Creamy Garlic Sauce
Increase the heat back to medium-high on the skillet, adding any remaining oil before tossing in minced garlic. Sauté the garlic for about 1-2 minutes until fragrant, stirring constantly to prevent burning. This aromatic base forms the foundation for your creamy garlic sauce in the Chicken Spaghetti Squash dish.
Step 6: Combine Sauce Ingredients
To the fragrant garlic, add heavy cream, chicken broth, Italian seasoning, kosher salt, and freshly grated Parmesan cheese. Stir everything together, and allow the mixture to come to a gentle simmer over medium heat. Watch as the sauce thickens and transforms into a rich coating that pairs perfectly with the spaghetti squash.
Step 7: Add Spinach and Sun-Dried Tomatoes
Once the sauce is bubbling, fold in the chopped fresh spinach and sun-dried tomatoes, stirring until the spinach wilts and integrates with the sauce. This vibrant addition not only boosts color but also adds essential nutrients to your irresistible Chicken Spaghetti Squash.
Step 8: Combine Squash with Sauce
After the spaghetti squash has finished roasting, carefully scrape its insides with a fork to create long, spaghetti-like strands. Add the shredded squash to the creamy garlic sauce and toss gently until each strand is well coated. This melding of flavors will highlight the comfort of your Chicken Spaghetti Squash dish.
Step 9: Serve with Chicken
To serve, plate the creamy Chicken Spaghetti Squash mixture and top each serving with slices of the rested chicken. For added richness and presentation, consider garnishing with extra Parmesan cheese and a sprinkle of freshly chopped parsley. Your delightful weeknight meal is now ready to be enjoyed!

Storage Tips for Chicken Spaghetti Squash

Reheating: When ready to eat, reheat in a skillet over medium heat with a splash of chicken broth or cream to restore the creamy texture of the Chicken Spaghetti Squash.

Expert Tips for Chicken Spaghetti Squash
-
Perfectly Cooked Squash: Aim to roast the spaghetti squash until fork-tender, typically 30-45 minutes, to ensure it holds its shape without becoming mushy.
-
Long Strands: When scraping the squash, use a fork at an angle. This technique generates longer strands that better hold onto the creamy sauce.
-
Avoid Watery Sauce: Let the roasted squash sit, cut-side down, to drain excess moisture. This prevents your sauce from becoming runny.
-
Mix Gradually: When adding Parmesan cheese to your sauce, introduce it gradually over medium-low heat. This method helps prevent curdling and ensures a smooth finish to the Chicken Spaghetti Squash.
-
Customize Flavor: Experiment with ingredient substitutions such as using fresh herbs instead of Italian seasoning, or try adding red pepper flakes for some extra warmth to the sauce.

Irresistible Chicken Spaghetti Squash Recipe FAQs
How do I choose the perfect spaghetti squash?
Absolutely! When selecting spaghetti squash, look for small to medium-sized squashes that feel heavy for their size and have a hard, matte skin. Avoid any that have dark spots or soft areas, as these can indicate that the squash is overripe or spoiled. The vibrant yellow color is also a good sign of ripeness!
How should I store leftover Chicken Spaghetti Squash?
You can store any leftovers in an airtight container in the fridge for up to 4 days. Be sure to let it cool completely before sealing the container to avoid condensation, which can make the dish soggy. If you’re looking to keep it longer, you can freeze individual portions in airtight containers for up to 2 months. This way, you can enjoy it as a quick meal later!
Can I freeze Chicken Spaghetti Squash? If so, how?
Absolutely! To freeze your Chicken Spaghetti Squash, let it cool completely first, then separate it into individual portions for convenience. Place each portion in an airtight container or freezer bag, making sure to remove any excess air before sealing. Label the bags with the date, and pop them in the freezer. To reheat, you can thaw in the fridge overnight or directly cook from frozen by adding a splash of broth or cream during reheating.
What if my spaghetti squash isn’t tender after roasting?
If your spaghetti squash isn’t tender after the suggested 30-40 minutes, don’t worry! Simply continue roasting it for an additional 5-10 minutes, checking periodically to see if it’s softened. You want it to be fork-tender, allowing for the perfect spaghetti-like strands. Remember, roasting times may vary based on the size of the squash, so keep an eye on it!
Are there any dietary considerations for Chicken Spaghetti Squash?
Very! This dish is inherently gluten-free, making it a fantastic option for those with gluten sensitivities or celiac disease. If you’re concerned about allergies, always check ingredients like chicken broth and Parmesan cheese, as some brands may include additives. Additionally, for a dairy-free option, substituting heavy cream with coconut cream is a delightful choice that retains creaminess.
How can I make this dish vegetarian-friendly?
The more the merrier! To transform the Chicken Spaghetti Squash into a vegetarian dish, simply replace the chicken with tofu or chickpeas for that protein kick. You can sauté the tofu until golden and incorporate it into the creamy garlic sauce just as you would the chicken. Feel free to add even more veggies, like bell peppers or mushrooms, to build a hearty, veggie-packed alternative!
