Step‑by‑Step Instructions for Pesto Chicken Stuffed Spaghetti Squash

Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This temperature is essential for roasting the spaghetti squash and chicken to perfection. Meanwhile, gather your baking sheet lined with foil, making clean-up a breeze. The foil will help the spaghetti squash roast evenly and capture all those delightful flavors as they meld together.

Step 2: Prepare the Spaghetti Squash
Carefully cut the large spaghetti squash in half lengthwise using a sharp knife. Scoop out the seeds and stringy insides—you want a clean base for your filling. Once cleaned, place the squash halves skin-side down on the prepared baking sheet. It’s important that they’re facing down to prevent moisture from making them soggy while roasting.

Step 3: Season and Place the Chicken
Next, take the chicken breast and cut it into halves. Season both sides with salt and pepper to enhance their flavor. Lay the chicken pieces on the same baking sheet as the squash, ensuring they have enough space to cook evenly. The chicken will absorb some of the flavors from the squash as they bake together, creating delightful synergy.

Step 4: Bake the Squash and Chicken
Slide the baking sheet into the oven and bake both the Pesto Chicken Stuffed Spaghetti Squash and chicken for about 45 minutes. After 30 minutes, it’s a good time to check the chicken to ensure it’s fully cooked—juices should run clear when pierced. The squash will be done when it feels tender and can easily be scraped into noodle-like strands with a fork.

Step 5: Scrape the Squash into Strands
Once cooked, remove the spaghetti squash and chicken from the oven. Let them cool briefly, then use a fork to scrape the flesh of the squash into strands. This process transforms the squash into a pasta-like texture, which is perfect for holding all the flavors of the filling. Set the strands aside in a large mixing bowl while you prepare to combine them with the chicken.

Step 6: Combine Chicken, Squash, and Pesto
Dice the cooked chicken into bite-sized pieces and add it to the bowl with the spaghetti squash strands. Pour in the pesto sauce, stirring everything together until well combined. This is where the magic happens—each strand will be coated in the vibrant flavors of your homemade (or store-bought) pesto, making each bite utterly delicious.

Step 7: Stuff the Squash Halves
Spoon the chicken and pesto mixture back into the hollowed spaghetti squash halves, generously filling each one. Make sure to pack it neatly, so every bite is packed with flavor. This step not only looks visually appealing but also ensures you get a hearty serving in each squash boat when it’s time to dig in.

Step 8: Top with Cheeses and Broil
Sprinkle the mozzarella and parmesan cheese over the stuffed spaghetti squash. This cheesy topping creates a delightful, melty layer that adds creaminess to your dish. Place the baking sheet back in the oven and switch to the broil setting. Broil for about 3-5 minutes, watching closely until the cheese is bubbly and golden brown.

Step 9: Serve and Enjoy Your Meal
Once the cheese has reached that perfect golden hue, carefully remove the baking sheet from the oven. Let the Pesto Chicken Stuffed Spaghetti Squash rest for a few minutes before serving. The aroma is irresistible, and each bite promises a delicious adventure that’s healthy and satisfying, making it a delightful dinner option for the whole family.

Make Ahead Options

These Pesto Chicken Stuffed Spaghetti Squash are fantastic for meal prep, allowing you to savor your favorite flavors while saving time during busy weeknights! You can cook and prepare the spaghetti squash and chicken up to 3 days in advance, storing them separately in airtight containers in the refrigerator. For optimal quality, refrigerate the cooked chicken and squash without the sauce, preventing them from becoming soggy. When you’re ready to enjoy, simply combine the squash and chicken with pesto and cheese, fill the squash halves, and broil them until the cheese is bubbly and golden—it’s just as delicious as when freshly made, minimizing your effort while maximizing flavor!
