How to Make Chicken Pesto Spaghetti Squash

Roast the spaghetti squash: Preheat your oven to 400°F (200°C). Cut the squash in half, scoop out the seeds, drizzle with 2 tablespoons of avocado oil, and sprinkle with a pinch of sea salt. Roast for about 35-40 minutes until fork-tender.
Prepare the pesto sauce: While the squash is roasting, gather your ingredients for the pesto. In a food processor, combine 2 cups of fresh basil leaves, 2/3 cup of pumpkin seeds, 1 large clove of garlic, and 1/4 teaspoon of sea salt. Pulse for a few moments, then stream in 2/3 cup of avocado oil until you achieve your desired texture.
Sauté the chicken: Heat a skillet over medium-high heat and add 1 to 2 tablespoons of avocado oil. Once hot, add 1 1/2 lbs of chopped boneless chicken thighs, followed by 1 teaspoon each of paprika and garlic powder, and 1/4 teaspoon of sea salt. Cook without stirring for 3 minutes until browned, then stir and cook for another 3 minutes. Cover and cook for an additional 2 to 5 minutes until fully cooked.
Combine the ingredients: Let the roasted squash cool slightly before fork-scooping out the “spaghetti” strands into a large mixing bowl. Add in the homemade pesto sauce and toss to combine. Gently fold in the chicken—be sure to include all of the flavorful juices—until everything is well mixed. Adjust the seasoning with more sea salt if needed.

Optional: Garnish with grated parmesan for an extra touch of flavor.

Make Ahead Options

These Chicken Pesto Spaghetti Squash are perfect for meal prep enthusiasts! You can roast the spaghetti squash up to 3 days in advance; just store the strands in an airtight container in the refrigerator. The pesto can also be prepared 24 hours ahead; just be sure to cover it to prevent browning. When you’re ready to serve, sauté the chicken and combine everything in a large mixing bowl. Simply reheat the roasted squash and pesto, add the chicken, and toss until well combined. This approach not only saves you time on busy nights but ensures your meal is just as delicious as when freshly made!
