Chicken Spaghetti Squash

I love spaghetti squash but I have to admit that I often get stuck in a rut where I either eat it with my favorite Bolognese sauce or with a little butter and salt. Pretty plain, right? It’s time to up the ante on this very versatile squash, once that is often overlooked simply because cooking it can seem like a bit of a burden.

Cooking spaghetti squash is not difficult since it can be cooked in a few different ways. As a matter of fact, check out this quick video on how easy it is to cook in the microwave, in the oven, or in the slow cooker.

Another reason I like eating spaghetti squash is that I can cook it ahead of time, shred it to get the meat out, and keep it in the fridge for a few days. At dinnertime, all I have to do is prepare the chicken portion of this dish, heat up the spaghetti squash, and serve.

This recipe is just like the ones in my third cookbook, The Best Grain-Free Family Meals on the Planet. The recipes in the book are naturally gluten and grain free and suitable for everyone who just loves really good food. Honestly, I would eat out of that book on a daily basis; and between us, I published it as a way to pass on my family’s favorite real-food recipes.

Once the spaghetti squash is cooked, the entire dish comes together quickly in a large pan, which is something I love due to its minimal cleanup.

  • Prep Time: 10 minutes
  • Cook Time: 20 minutes
  • Total Time: 30 minutes
  • Yield: 4 servings 1x
  • Category: Dinner
  • Cuisine: American/Low-Carb


  • 1 large spaghetti squash, washed
  • 2 boneless, skinless chicken breasts
  • 1 tablespoon + 1 teaspoon Italian seasoning, divided
  • 2 tablespoons olive oil, divided
  • 2 tablespoons lemon juice, about 1 lemon
  • 1/4 cup unsalted butter
  • 3 cloves garlic, minced
  • 1 cup half and half
  • pinch of red pepper flakes
  • 1/2 cup Parmesan cheese
  • 2 tablespoons chopped fresh parsley leaves


  1. Cook spaghetti squash until tender. Check out this video to see 3 easy methods to cook your spaghetti squash.
  2. While your spaghetti squash is cooking, season chicken breasts with 1 tablespoon Italian seasoning, salt, and pepper.
  3. On a large skillet, heat up 1 tablespoon of olive oil. Add chicken breasts and cook, flipping once, until cooked through, about 5 minutes per side. Add lemon juice, let it bubble, turn off the heat, remove chicken from skillet onto a cutting board, slice diagonally, and set aside.
  4. In a microwave-safe glass or small saucepan, heat up half and half.
  5. To the same large skillet over medium-high heat, melt butter, add garlic, and cook, stirring constantly for about one minute, until the garlic is fragrant and heated through. Slowly, add in half and half, 1 teaspoon Italian seasoning, and red pepper flakes. Stir in the Parmesan cheese and stir until the mixture has slightly thickened. Cook, stirring constantly until everything is incorporated into a sauce.
  6. Add the chicken back into the skillet or large pan, turn heat to simmer (lowest heat setting) and heat the chicken through.
  7. With a fork, scrape the squash meat off each half into a large bowl or directly onto 4 plates. Top with chicken and lemon-garlic sauce, sprinkle with fresh parsley and serve.


  • Make sure to heat the half & half prior to adding it to the skillet. This will prevent the sauce from curdling.
  • If you don’t have spaghetti squash, you can serve this recipe over regular or gluten-free pasta.

      Thank you for trying!

    can I use 1% milk instead?

    1. Laura Fuentes says:

      you can, but it might be a bit … runny.

  7. Jonathan says:

    Going to try it substituting white wine for the lemon, I love this recipe just do not have any lemon, so I will improvise and try with lemon at a later date, I will let you all know how it turns out

  8. Paula says:

    How was it with the wine in place of lemon?

    1. Laura Fuentes says:

      works well.

  9. Lisa F says:

    Is that correct that it is only two boneless skinless chicken breasts for four servings?

    1. Laura Fuentes says:

      Yes, two boneless chicken breasts are about 1 pound, at 4ounces of protein per person and the spaghetti squash is a generous portion. Of course, you can add a third.

  10. Donna says:

    Made this meal last night……delicious,! Loved by the whole family. I was told to “put it in the rotation” of favorite dinners. Appreciate the detailed recipe directions, easy to follow.

    1. Laura Fuentes says:

      Its in our regular rotation as well!

  11. LL says:

    My family loved it though the sauce was kind of curdled.

  12. Roxane says:

    Just made this tonight and it tastes delicious!

    1. Laura Fuentes says:

      I’m so glad you enjoyed it Roxane!

  13. Mikaela says:

    Food was delicious but may need to note that when adding the half & half, that you need to be sure the pan is cool. Iron skillets apparently hold too much heat and will curdle the milk. It tasted fine, just had an off texture.

  14. Linda says:

    Can coconut milk be substituted for the half and. Half

  15. Alison Young says:

    Yum! My picky 8 year old who never eats seasoned food actually liked the chicken. He wasn’t keen on the spaghetti squash but it’ll take any win I can get. My husband & I loved all of it. Plus I made extra chicken so there are leftovers!!

  16. Christa says:

    This was so tasty! Just one question.. The sauce was cooking perfectly but right before I was about to pull the chicken off, it seemed like the butter started to separate from the rest of the sauce. Could I possibly not have heated the half and half up long enough? Or did I just leave it on a bit too long? Any tips are appreciated!

    1. Laura Fuentes says:

      Hi Christa, this “separation” sometimes happens when the half and half is too cold when it goes in the pan. As it’s heated, the dairy proteins separate. You can avoid this by warming it up first and whisking it continuously. I am so glad you enjoyed the recipe!
