Irresistible Chicken Spaghetti Squash Ingredients
For the Squash
• Spaghetti Squash – The star of this dish, providing a pasta-like texture; choose small to medium-sized, pale yellow squash for optimal results.
For the Chicken
• Unsalted Butter – Adds richness to the chicken when sautéing; consider using olive oil for a delicious dairy-free alternative.
• Vegetable Oil – Essential for searing chicken and making the creamy sauce; any neutral oil, like canola, works well.
• Chicken Breasts – Boneless and skinless is best for a hearty protein component; feel free to swap for turkey for extra lightness.
For the Sauce
• Garlic – Fresh minced garlic brings a robust flavor to your sauce; don’t skimp on this aromatic ingredient!
• Italian Seasoning – A delightful blend of herbs that enhances the overall taste; for a homemade touch, mix dried oregano and basil.
• Chicken Broth – Adds depth to the sauce; using low-sodium broth helps control salt levels.
• Kosher Salt – A vital seasoning for both chicken and sauce; adjust according to your taste preferences.
• Parmesan Cheese – This provides a creamy texture and savory goodness to the sauce; freshly grated is ideal or go for nutritional yeast for a vegan option.
• Heavy Cream – Ensures a luxurious finish for the sauce; coconut cream offers a fabulous dairy-free substitute.
• Sun-Dried Tomatoes – Introduces a sweet and tangy flavor; you can swap for fresh tomatoes, keeping in mind texture changes.
• Fresh Spinach – Brightens up the dish with color and nutrients; replace with kale or chard for variety.
This Irresistible Chicken Spaghetti Squash is not just a healthy dinner option—it’s an invitation to a flavor-packed, comforting meal that your family will love!
Step‑by‑Step Instructions for Irresistible Chicken Spaghetti Squash
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup. This will create a perfect cooking environment for the spaghetti squash, ensuring it roasts evenly and develops a lovely golden color during the baking process.
Step 2: Prepare the Spaghetti Squash
Carefully slice the spaghetti squash in half lengthwise, using a sharp knife. Place the halves cut-side down on the prepared baking sheet, and pop them into the oven. Bake for 30 to 40 minutes until the squash is fork-tender, and the flesh easily separates into strands—this is when it truly becomes the star of your Irresistible Chicken Spaghetti Squash!
Step 3: Scoop the Squash
Once the spaghetti squash is done baking, remove it from the oven and let it cool for a few minutes. Using a large spoon, scoop out the seeds and stringy bits from the center. Then, take a fork and gently shred the insides into spaghetti-like strands. Set this aside while you prepare the rest of your dish.
Step 4: Season and Cook the Chicken
While the squash cools, season the boneless, skinless chicken breasts with kosher salt and pepper. In a large skillet, heat a combination of unsalted butter and vegetable oil over medium-high heat. Add the chicken to the hot skillet, searing it for about 5-7 minutes until it’s golden brown on one side before flipping and covering the pan to cook until internal temperature reaches 165°F (75°C).
Step 5: Make the Creamy Sauce
After removing the chicken from the pan, lower the heat and add more vegetable oil if needed. Sauté freshly minced garlic until fragrant, about 1 minute. Gradually stir in heavy cream and chicken broth, followed by the Italian seasoning. Continue stirring until the mixture simmers. Slowly add in the Parmesan cheese, mixing until it melts into a smooth and creamy sauce that is incredibly fragrant.
Step 6: Combine Filling Ingredients
Next, add fresh spinach and sun-dried tomatoes into the sauce. Stir gently until the spinach wilts, which should take just a couple of minutes. Then, fold in the shredded spaghetti squash until well combined, mixing everything together so that the flavors meld. Taste and adjust the seasoning if necessary, perhaps adding a squeeze of lemon for brightness.
Step 7: Plate and Serve
Finally, slice the cooked chicken breasts and either mix them into the squash mixture or serve them on top for a beautiful presentation. Garnish with additional Parmesan cheese and fresh parsley for a pop of color. Serve your Irresistible Chicken Spaghetti Squash hot, allowing everyone to enjoy this comforting and healthy family dinner!
