Chicken Pesto Spaghetti Squash features delicious homemade pesto sauce and tender chicken for an easy, satisfying, nourishing dinner recipe that happens to be paleo, whole30, and! Make it for the whole family or as a meal prep recipe.
If I had a dollar for every time I’ve made this chicken pesto spaghetti squash…
…I’d be cashing in early retirement in the Maldives.
It’s one of those meals that covers all the bases and is just so nice to cozy up to on a chilly evening.
The best part about this recipe is you can either prepare it in parts – roast the spaghetti squash and/or make the pesto sauce up to 5 days in advance, or make everything as the squash is roasting.
Bonus: you can customize the recipe to your heart’s delight by changing up the pesto recipe or using different animal protein.

Let’s whip it out!
How to Make Chicken Pesto Spaghetti Squash:
Begin by roasting a medium to large-sized spaghetti squash. If you’ve never roasted a spaghetti squash, no sweat! I made a nifty little tutorial on How to Roast Spaghetti Squash, which you can follow!
Once the squash has finished roasting, allow it to cool.
While the squash is roasting, prepare the homemade pesto sauce.
To do so, add all ingredients except the oil to a food processor. Pulse a few times to chop the ingredients. Leave the food processor on and stream oil through the top. Continue processing until desired texture is reached.
Heat a skillet to medium-high and add 1 to 2 tablespoons avocado oil or coconut oil. Add the chopped chicken, sea salt, paprika, and garlic powder.
Brown the chicken without stirring for 3 minutes. Stir and continue browning without touching another 3 minutes.
Cover the skillet with a lid, and cook until the chicken is cooked through, about 2 to 5 minutes more.
Once the squash is cool enough to handle, transfer the “spaghetti” strands to a large mixing bowl.
Add in the pesto sauce and toss well. Stir in the chicken, including all of the liquid, and toss until everything is combined.
Taste for flavor, and add sea salt to taste.
Recipe Adaptations:
- Turn this into a casserole by following all the steps outlined in the recipe, then transfer everything to a casserole dish and bake for 20 to 30 minutes at 375. If you aren’t dairy-free, be sure to give it a hefty shower of grated mozzarella and parmesan cheese.
- Use any type of homemade or store-bought pesto sauce. Just be sure you’re using 1 to 1.5 cups.
- Replace the chicken with shrimp or ground turkey.
- If you don’t follow a strict paleo or whole30 diet, add 1 cup grated parmesan cheese to the pesto sauce.

Can’t wait to try this! Cooking for my 88 year old mom, and was wondering if this could be frozen for individual portions

Hi Terry! That's so sweet of you to make the recipe for your mom! I haven't tried freezing it myself but I think it would work. Because there's a decent amount of sauce (and fat), it should thaw just fine. I hope she enjoys the recipe!

This was fantastic! Made this for dinner and it was superb. I used almonds in the pesto (previously I’ve only used pine nuts in pesto but didn’t have any on hand), and no cheese. It was a big hit for my mom and I! I love pesto and she has many allergies including dairy, added sugars, barley, etc. so not only was this exciting to find something delicious, but something so delicious that she could enjoy too! 10/10, will make again!

How much pesto is needed in this recipe if using storebought or preprepared? And, is spaghetti squash peel edible? I never peel my butternut squash as it's thin, gets very soft while cooking and is delicious. Just wondering about spaghetti squash as this is my first time to cook with it.

@Julia, The recipe card has the ingredients for making the pesto but not for buying it already prepared. If one makes up the recipe as specified, how much does it make, i.e, 1/2 cup, etc??

Hi Sara! There is a recipe card at the end of the post that has the breakdown of all of the ingredients with their measurements. You can either scroll down or slick the 'Jump to Recipe' link at the top of the page, which will take you right there :) Spaghetti squash peel is edible. To be honest, I personally wouldn't eat it because the texture is a little rough. Hope you enjoy the recipe! xo

This was delicious. I made as is except I had some leftover rotisserie chicken & already had some homemade pesto so that shortened the prep/cooking time. Thanks for a great recipe!

This is AMAZING! Just cooked it to meal prep lunches for the week and of course had to taste it. I could have eaten the whole bowl! Yum yum yum! I used pine nuts in the pesto and no cheese. So good!
