How to Make Pesto Chicken Stuffed Spaghetti Squash
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F to ensure it’s hot enough when you’re ready to bake.

- Cut each spaghetti squash in half lengthwise.

Place each half of the squash facing down in a baking dish. Bake for 35-45 minutes until tender. The strands should be easy to fluff with a fork.

Common Mistakes to Avoid
When making pesto chicken stuffed spaghetti squash, it’s easy to run into some common pitfalls. Here are some mistakes to steer clear of:
Skipping the seasoning: Not adding salt and pepper can make your dish bland. Always season your spaghetti squash before adding the filling for a flavor boost.
Overcooking the squash: Cooking spaghetti squash for too long can lead to mushy strands. Check for doneness at the lower end of the baking time to maintain a firm texture.
Ignoring the chicken preparation: Rushing through cooking the chicken can result in unevenly cooked meat. Ensure it’s fully cooked and shredded properly for even distribution in the dish.
Using too much pesto: Excess pesto can overwhelm the other flavors. Start with a small amount and adjust according to your taste preferences.
Not fluffing the squash: Forgetting to fluff the spaghetti squash strands makes it harder to mix with the filling. Use a fork to separate strands thoroughly for better integration.
