Chicken Spaghetti Squash Ingredients

For the Spaghetti Squash
• Spaghetti Squash – Provides a pasta-like texture without the carbs. Look for small to medium-sized squashes with hard, matte skins.

For the Chicken and Sauce
• Unsalted Butter – Adds richness and flavor to the chicken during cooking. Substitute with olive oil for a dairy-free option.
• Vegetable Oil – Used for searing chicken and cooking the sauce. Can be replaced with any neutral oil.
• Chicken Breasts (boneless & skinless) – The main protein source. Ensure they are room temperature for even cooking.
• Garlic (minced) – Imparts strong, aromatic flavor to the sauce. Fresh garlic is recommended for best results.
• Italian Seasoning – Enhances flavor complexity in the sauce. Fresh herbs like basil or oregano can be swapped for a fresher taste.
• Chicken Broth – Adds depth to the sauce. Low-sodium options are available to control salt levels.
• Kosher Salt – Used for seasoning chicken and sauce. Table salt can be used but adjust quantity due to different saltiness levels.
• Parmesan Cheese (freshly grated) – Provides creaminess and enhances flavor. Use nutritional yeast for a dairy-free option.
• Heavy Cream – Creates the creamy texture of the sauce. Can be replaced with coconut cream for a dairy-free alternative.
• Sun-Dried Tomatoes – Adds sweetness and texture. Fresh tomatoes can be substituted, but adjust cooking time.
• Fresh Spinach – Adds nutrients and color, wilts down into the dish. Kale can be used as a fibrous alternative.

Final Touches

Step‑by‑Step Instructions for Chicken Spaghetti Squash

Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C) while preparing a baking sheet lined with parchment paper. This setup will make it easy to clean up later. As the oven heats, grab your spaghetti squash, ensuring it’s firm and without blemishes, and get ready to halve it for roasting.

Step 2: Roast the Spaghetti Squash
Carefully slice the spaghetti squash in half lengthwise. Place the cut-side down on your prepared baking sheet and bake for 30–40 minutes. The squash is ready when it’s tender and can be easily pierced with a fork. You’ll know it’s perfect when its skin gives slightly to the touch!

Step 3: Shred the Squash
Once roasted, remove the spaghetti squash from the oven and allow it to cool slightly before handling. Scoop out the seeds, and then, using a fork, shred the flesh into strands. It should resemble spaghetti, making this Chicken Spaghetti Squash dish a delightful low-carb alternative.

Step 4: Season and Sear Chicken
While the squash cools, take your boneless, skinless chicken breasts and season both sides generously with kosher salt and pepper. Heat a skillet over medium-high heat and add unsalted butter and vegetable oil. Sear the chicken for about 6-7 minutes until it’s golden brown, then reduce the heat, cover, and cook until the internal temperature reaches 165°F (75°C).

Step 5: Sauté Garlic
Once the chicken is cooked, remove it from the pan and keep it warm. In the same pan, increase the heat slightly and add more vegetable oil along with minced garlic. Sauté for about 1 minute until fragrant, stirring frequently to avoid burning, as you set the stage for the luscious creamy sauce.

Step 6: Create the Creamy Sauce
Pour in the heavy cream and chicken broth, then sprinkle in the Italian seasoning, kosher salt, and Parmesan cheese. Stir the mixture until the cheese fully melts and becomes creamy, about 2-3 minutes. This rich sauce will beautifully coat your chicken and the shredded squash, enhancing the flavors of your Chicken Spaghetti Squash dish.

Step 7: Combine ingredients
Add in the fresh spinach and sun-dried tomatoes, stirring until the spinach wilts, about 2 minutes. Then, gently fold in the shredded spaghetti squash, ensuring every strand is coated in that delicious creamy sauce. Once mixed, it’s a comforting bowl of Chicken Spaghetti Squash waiting to be served.

Step 8: Serve and Garnish
Slice the seared chicken into strips and either stir it into the squash mixture or serve it on top. For a beautiful presentation, garnish the dish with extra freshly grated Parmesan cheese and chopped parsley, adding a lovely pop of color before serving hot. Enjoy this delightful twist on pasta night!

Chicken Spaghetti Squash Recipe FAQs

How do I choose the best spaghetti squash?
Look for small to medium-sized squashes with firm, hard, and matte skins. Avoid any with dark spots or soft spots as these could indicate over-ripeness. A good spaghetti squash should feel heavy for its size and should not have any blemishes on its surface.

What is the best way to store leftover Chicken Spaghetti Squash?
Store any leftovers in an airtight container in the refrigerator for up to 4 days. When ready to enjoy it again, reheat gently in the microwave or on the stovetop, adding a splash of chicken broth to keep it moist and help restore its creamy texture!

Can I freeze Chicken Spaghetti Squash?
Absolutely! To freeze, allow the dish to cool completely, then transfer it to a freezer-safe container. It can be stored for up to 2 months. When you’re ready to enjoy it, thaw it in the refrigerator overnight and reheat gently. Be aware that while the flavor will remain delicious, the texture of the squash may change slightly upon thawing.

What should I do if my spaghetti squash is too mushy?
If your spaghetti squash turns out mushy, it may have been overcooked. For future reference, aim for fork-tender squash that still holds its shape. If it’s already too soft, you can still use it by mixing it with less sauce or adding a bit of grated cheese, which can help to absorb some of the moisture.

Are there any dietary concerns with this dish?
This Chicken Spaghetti Squash dish is generally family-friendly, but for those with dietary restrictions, you can easily make it dairy-free by substituting heavy cream with coconut cream and Parmesan cheese with nutritional yeast. For anyone concerned about allergies, double-check that your chicken broth and any additional ingredients do not contain common allergens.
