Step‑by‑Step Instructions for Irresistible Chicken Spaghetti Squash with Creamy Garlic Sauce
Step 1: Prepare Squash
Preheat your oven to 400°F (200°C). Carefully slice the spaghetti squash in half lengthwise, ensuring to keep your fingers safe. Place the squash cut-side down on a parchment-lined baking sheet. Bake for 30-40 minutes, or until the flesh is tender and easily shredded with a fork, giving you those lovely spaghetti-like strands.
Step 2: Cook Chicken
While the squash bakes, season the boneless, skinless chicken breasts with kosher salt and pepper. In a large skillet, melt unsalted butter and heat vegetable oil over medium-high heat. Sear the chicken for about 5-7 minutes until golden brown. Flip, cover, reduce the heat, and continue cooking until the internal temperature reaches 165°F (74°C). Remove chicken and let it rest, keeping it warm.
Step 3: Make Sauce
Using the same skillet, add any remaining vegetable oil and sauté the minced garlic over medium heat for about 1 minute, until fragrant but not burnt. Pour in the heavy cream and chicken broth, stirring to combine. Then add Italian seasoning and salt, bringing the mixture to a gentle simmer. Gradually stir in the grated Parmesan cheese until melted and smooth, creating your luscious creamy garlic sauce.
Step 4: Combine Ingredients
Once your sauce is ready, fold in the chopped fresh spinach and sun-dried tomatoes, letting the spinach wilt for a minute. Carefully contribute the shredded spaghetti squash into the pan, mixing until every strand is well coated with that decadent creamy sauce. Taste and adjust seasoning if needed for a burst of flavor in your Chicken Spaghetti Squash.
Step 5: Serve
Slice the rested chicken into strips and either toss it with the spaghetti squash mixture or artfully place it on top for presentation. If desired, return the delectable mixture to the empty squash shells for a stunning serving option. Garnish with extra Parmesan and fresh parsley for a beautiful final touch, making your Irresistible Chicken Spaghetti Squash a delightful centerpiece at the dinner table.

Chicken Spaghetti Squash Recipe FAQs
What is the best way to choose a ripe spaghetti squash?
Look for a spaghetti squash that has a firm and heavy feel, with a smooth, golden-yellow skin. Avoid any with soft spots or bruises, as these indicate over-ripeness. It should feel solid without any dark spots, which can be a sign of spoilage.
How should I store leftover Chicken Spaghetti Squash?
Keep your Chicken Spaghetti Squash stored in an airtight container in the refrigerator for up to 4 days. This helps retain its delicious flavors and prevents any moisture loss. Just make sure to let it cool down to room temperature before sealing it up to avoid condensation buildup.
Can I freeze Chicken Spaghetti Squash? If so, how?
Absolutely! To freeze your Chicken Spaghetti Squash, allow it to cool completely, then portion it into freezer-safe containers or bags. It can be stored in the freezer for up to 2 months. When reheating, it’s best to thaw in the refrigerator overnight before warming. This method helps to maintain the texture.
What should I do if my spaghetti squash is too watery?
If you find your spaghetti squash is watery, no worries! First, after baking, place the squash cut-side down on a paper towel to absorb excess moisture for about 10-15 minutes. Alternatively, sauté the squash strands briefly in a pan over medium heat. This not only helps reduce the water content but also enhances the flavors.
Are there any dietary considerations for Chicken Spaghetti Squash?
Yes, this dish can easily accommodate various dietary preferences! For a dairy-free option, substitute heavy cream and parmesan cheese with coconut cream and nutritional yeast. If you’re cooking for those with allergies, make sure to clearly identify ingredients like spices and oils. This recipe is also gluten-free when using proper broth, and you can easily swap in turkey or tofu for a different protein source if needed.
Can I use other vegetables with the Chicken Spaghetti Squash?
The more the merrier! You can definitely experiment by adding other vegetables such as bell peppers, zucchini, or mushrooms. Just remember to sauté harder vegetables a bit longer to ensure they’re tender and flavorful before mixing them into the creamy sauce.
