    Jump to Recipe Print Recipe

    Fresh basil makes this spaghetti squash casserole chicken caprese such a fresh and flavorful dish. 

    Prepping the spaghetti squash and shredded chicken ahead of time makes this casserole so fast and easy to make! Meal prepping? Make double the chicken and squash and make my Spicy Peanut Butter Noodles.

    Over the Spoon for:

    • Rich in vitamins, minerals, and antioxidants
    • Full of filling fiber

    What do you need:

    • spaghetti squash
    • cooked shredded chicken
    • Red Pesto- this is a pesto sauce made from sundried tomatoes

    • fresh mozzarella 
    • Fresh Basil

    If you can't find red pesto sauce you can sub a basil pesto but be sure to add some sundried tomatoes!

    mixing casserole ingredients
    casserole dish topped with mozzarella
    1. Preheat oven to 375 Fahrenheit.
    2. Strain cooked and shredded Spaghetti Squash to remove as much moisture as possible (you can do this by either pressing down with a colander or use a cheese cloth.
    3. In a large bowl mix squash, chicken, garlic powder, and pesto.
    4. Place in a casserole dish topped with mozzarella slices and bake for 20 minutes.
    5. Top with fresh basil and balsamic glaze.

    Tips:

    • Strain the spaghetti squash as much as possible to reduce any excess moisture! 
    • Cook the spaghetti squash ahead of time with my favorite microwave method: How to Cook Spaghetti Squash (in the microwave)
    • To save time use shredded rotisserie chicken
