Pesto Chicken Spaghetti Squash is an easy healthy dinner recipe - low-carb, keto, paleo, whole30, delicious

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 you-ify the recipe to your heart’s delight by changing up the pesto recipe or using different animal protein. Craving additional veggies like cauliflower, broccoli, bell pepper, or carrot? Toss ‘em in!

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 cumin. Brown the chicken without stirring for 3 minutes. Stir and continue browning without touching another 3 minutes. Stir chicken well, cover, and cook until 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. Add 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.

I made this recipe for my dinner tonight. It is very good and I know I will make it again. I reduced the ingredients because I only cook for one. I used a small spaghetti squash, which I cooked In the Instant pot. I used one chicken breast , and reduced the amount of the spices. I also added an onion to the chicken while it browned in the skillet.

My pesto was Costco’s brand, Kirkland.

This is so delicious to eat. Thank you.

Do you have a low FODMAP version of this? I'm wondering what to substitute for the garlic in the pesto sauce

Julia

Hi Margaret! I replace garlic with cider vinegar or lime juice. I'd say start with 1 tablespoon of either and adjust up according to your personal taste :D Hope you enjoy! xo
