You are going to LOVE this Whole30 Greek Chicken Spaghetti Squash Bake. Spaghetti squash gets roasted + shredded then tossed with chicken, olives, sun dried tomatoes, basil, and artichokes.

The mixture then gets baked in the oven to form a casserole-like dinner that is packed with veggies and so yummy!

This recipe is inspired by this Whole 30 Tuscan Chicken Spaghetti Squash recipe from my friend Chrissa at Physical Kitchness.

The idea of baking spaghetti squash in a casserole like form basically blew my mind last year, and after trying it I proceeded to come up with all different variations of spaghetti squash bakes (Including this Healthy Buffalo Chicken Spaghetti Squash Casserole!)

We love all things greek food from Greek Chicken Kabobs to Greek Chicken Thighs.

This Whole30 Greek Chicken Spaghetti Squash Bake recipe is something you can get on the table in just about 30 minutes if you time it right or plan ahead.. so let me explain.

Ya gotta multi-task!

It’s important that you get the spaghetti squash in the microwave or instant pot to cook first. That takes the longest.

Time Saving Tips for making this Greek Chicken Spaghetti Squash Bake

  • Cook the spaghetti squash ahead of time.
  • Cook the chicken ahead of time – You can make my Easy Instant Pot Shredded ChickenCrockpot Shredded Chicken Recipe you can cook the chicken in the crockpot or Roast a Whole Chicken (you’d have to do it the day before or in the morning)
    • OR you buy a rotisserie chicken and shred it up.. any method will work!
  • While your chicken/spaghetti squash are cooking – you can prep the other minimal ingredients, so that you can get it in the oven in no time!
  • Prep the entire dish ahead of time (maybe on a Sunday) put it in the fridge + then just take it out and bake it when you’re ready for dinner!

Between getting dinner on the table super quickly + making something oh, so delish – you’re about to 100% win the dinner time hustle and feel like a superhero!

Substitutions for this recipe:

If you don’t like sun dried tomatoes, olive or artichokes, you can omit them and just sub in more of one of the other ingredients.

Basil – You can sub the 1/4 cup fresh basil for 1/2 tablespoon dried basil. It won’t be nearly as flavorful! I highly recommend getting the fresh herbs. You can even add in some fresh parsley for more flavor

Cheese – If you’re not doing a Whole30 or following a strict paleo diet this is delicious with some parmesan cheese on top!

Do you need to bake this if all the ingredients are already cooked?

Technically no you don’t need to, however I would recommend it. By baking the casserole with all the ingredients together it allows the flavors to meld and it makes it that much better!

If you’re pressed for time you could totally just toss all the cooked ingredients together in a skillet!

    This was my first recipe of yours to try. I’ve lost 159 pounds and my personal trainer and I are now focusing on clean eating rather than using fake or highly processed foods while I heal from skin removal surgery and can’t work out for 12 weeks. This recipe is easily a 10/10 and was so easy to make. The flavor is incredible and I’ll be making this again in the near future.

  3. Looking forward to this! I realized I forgot to account for portion sizing and I mixed up probably three times more than we’ll eat at this point… any chance this could be frozen?

    1. The Clean Eating Couple says:

      I’ve never tried freezing it so I’m not sure, but if I were you I’d bake it first, then freeze it!

    I love love Greek food and I thought this was delicious for a healthy weeknight dinner!

    1. The Clean Eating Couple says:

      So happy to hear this! Thank you!!

    This will go into the weekly rotation for sure! I subbed out chicken for ground turkey because we were chickened our this week already and the family and friend we had over for dinner DEVOURED many plates of this deliciousness!

    1. The Clean Eating Couple says:

      So glad you liked it, Jenna! Thank you!

  6. 5 stars
    We loved this! Tweaked it slightly. We do not like sundried tomato, so did roasted red bell pepper instead. Added feta cheese, so YUMMY! Definitely a keeper recipe.

    1. The Clean Eating Couple says:

      Love that substitution, Sherri! I want to try that!

    I love the flavors in this dish! I’ve also used the same ingredients and served it over zucchini noodles when I don’t have to time to cook up a whole spaghetti squash. Cheesy, Mediterranean goodness!

    1. The Clean Eating Couple says:

      That’s a great idea to serve it over the zoodles!! Glad you enjoyed it 🙂

    I made this yesterday to have for my lunches for the week and I’m sooo excited about it! It smelled like pizza when I took it out of the oven! I had some shredded Parmesan on hand, so per the recommendation, I added 2oz Parmesan to the top! This was super easy to put together, but as she mentions, you just have to plan ahead so that you have the spaghetti squash and chicken cooked. I threw my chicken in the crockpot on Saturday so that it was ready to go for meal-prep on Sunday. I do carb-cycling so this dish is great for low-carb days.

    1. The Clean Eating Couple says:

      Thank you so much Mindy! The parm on top was a good move – it makes this even better! Enjoy!!

      Thank you so much, Maurita! I’m so glad you and your family loved the recipe 🙂
