How to Make Pesto Chicken Stuffed Spaghetti Squash
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. This ensures that your spaghetti squash cooks evenly.
Step 2: Prepare the Squash
- Cut each spaghetti squash in half lengthwise.
- Remove all seeds using a spoon. If it’s too hard to cut, microwave the squashes for 5-10 minutes to soften them.
Step 3: Roast the Squash
Place each half of the spaghetti squash face down in a baking dish. Bake them for 35-45 minutes until they are tender enough to fluff with a fork.
Step 4: Cook the Chicken
While your squashes are baking:
1. Prepare shredded chicken using your preferred method. You can boil chicken breasts for about 20 minutes or opt for an instant pot or slow cooker.
Step 5: Make the Pesto
In a food processor:
1. Combine all ingredients for homemade pesto.
2. Blend until mostly smooth. If using store-bought pesto, skip this step.
Step 6: Mix Chicken and Pesto
In a bowl:
1. Toss shredded chicken with prepared pesto.
2. Gently fold in halved cherry tomatoes.
Step 7: Fluff the Squash
Once cooked:
1. Use a fork to fluff up each half of the spaghetti squash, scraping strands from the sides.
2. Season with salt and pepper.
Step 8: Assemble the Dish
Evenly distribute the chicken pesto mixture over each half of the fluffed squash:
1. Fold in some of the squash strands with the filling mixture.
2. Top each half with cheese if desired.
Step 9: Final Bake
Return stuffed squashes to the oven:
1. Bake for an additional 20 minutes or until everything is warmed through.

Common Mistakes to Avoid
Avoiding common mistakes can enhance your cooking experience and ensure your Pesto Chicken Stuffed Spaghetti Squash turns out perfectly.
- Overcooking the squash: If you bake the spaghetti squash too long, it may become mushy. Keep an eye on it and test for doneness by fluffing with a fork.

- Not seasoning properly: Lack of seasoning can result in bland flavors. Always taste and adjust salt and pepper before serving.
- Ignoring chicken preparation methods: Using dry or overcooked chicken will affect the dish’s overall quality. Opt for moist, shredded chicken for the best texture.
- Skipping the cheese topping: While optional, cheese adds a delightful creaminess. Don’t skip it if you enjoy cheesy flavors!
- Forgetting to fluff the squash: Not fluffing the spaghetti squash strands properly may lead to a clumpy texture. Make sure to scrape and mix thoroughly.
