Spaghetti squash with chicken
You'll love Mediterranean flavors of this easy dinner recipe. The spaghetti squash is first roasted in the oven, and then stuffed with sliced cooked chicken, garlic cherry tomatoes, spinach, and feta cheese. Everything is seasoned with smoked paprika and oregano. It's a very simple recipe, yet the flavors are rich and complex. This dish is gluten-free, low in calories, low in carbs, and high in protein and fiber. The only dairy product used is feta cheese, there is no cream and no butter. You can easily make it dairy-free by using dairy-free feta cheese.

Why you'll love it
- Nutrient-dense dinner. This incredibly easy recipe is a well-balanced meal that has everything: lots of veggies (spaghetti squash, tomatoes, and spinach), protein (chicken), and healthy fats (feta cheese).
- Healthy pasta alternative. Spaghetti squash is a healthy, delicious, low-calorie, and gluten-free alternative to regular pasta.
- Easy-to make. It's a simple dinner that a whole family will love! Easy enough to make it on a busy weeknight, yet the presentation is so appealing that you can serve it when you have company over.
Main ingredients
- Spaghetti squash is low in calories and incredibly nutritious, and a good source of folic acid, potassium, and beta-carotene.
- Chicken. You can use skinless boneless chicken thighs, chicken breasts, or tenderloins. This recipe is also great for leftover cooked chicken or rotisserie chicken!
- Spinach is packed with nutrients and antioxidants. It’s high in fiber and a good source of many vitamins and minerals. Spinach is a great source of vitamins A and C, as well as folic acid, iron, and calcium. I used fresh spinach, but frozen spinach can certainly be used! Make sure to thaw it and drain it from any liquid. I would even pat it dry with paper towels.
- Tomatoes. I used red cherry tomatoes.
- Feta cheese is quite nutritious, as well, and is a great source of calcium. This delicious cheese has a soft texture and briny flavor.
- Seasonings include smoked paprika, dried oregano, salt, and freshly ground black pepper.
- Olive oil is used to brush spaghetti squash halves before roasting.
How to roast spaghetti squash
You will need 2 medium spaghetti squashes. Carefully slice each one in half, and scoop out the seeds. (Tip: you can microwave each spaghetti squash for about 5 or 10 minutes to soften it a bit before slicing the squash in half. Make several large slits in the squash before microwaving.) You will have 4 squash halves. Roast the squash cut sides down in the preheated oven at 400 F for about 40 minutes.
Tips for Success
- To use cooking time efficiently, make the chicken, spinach, tomato and feta cheese mixture while you roast the spaghetti squash in the oven.
- Fresh spinach or frozen. I used fresh spinach but frozen spinach (thawed and drained well of all liquid) can be used here, as well.
- Use leftover chicken. This recipe works great with leftover cooked chicken, grilled chicken, or rotisserie chicken.
Storage and reheating tips
- Fridge. Refrigerate the leftover spaghetti squash stuffed with chicken in an airtight container for up to 4 days.
- Reheat in the oven. Reheat it in the preheated oven at 350 F for about 30 minutes.
- Reheat in the microwave oven. You can also microwave the leftovers. For the best and fastest results, take the chicken mixture out of the squash, and reheat this mixture and the squash separately. Then stuff the chicken mixture back into the spaghetti squash.
What to serve with it

Ingredients
Spaghetti squash
- 2 medium spaghetti squash
- 2 tablespoons olive oil
- salt and pepper
Chicken
- 2 tablespoons olive oil
- 1 lb skinless boneless chicken thighs or breasts
- ½ teaspoon smoked paprika
- ½ teaspoon dried oregano

Instructions
How to roast spaghetti squash
- Preheat oven to 400 Fahrenheit. Line the baking sheet with parchment paper.
- Cut the squash in 2 halves, scrape out the seeds and the fiber out of each half. Repeat with a second squash.
- (Note: before cutting each squash, you can microwave it. In this case, make large slits with a knife in a spaghetti squash along the line where you will slice it in half. Then, microwave the whole squash for about 5 or 10 minutes to soften it a bit. Then cut each squash in half.)
- Drizzle olive oil over the cut sides and inside of the squash. Generously season with salt and pepper.
- Place the 4 squash halves on the prepared baking sheet cut side down.
- Bake for about 30 or 40 minutes on the middle rack. Remove it from the oven when it's cooked through and soft. You can check by pulling the baking sheet out of the oven and piercing the squash with the fork - it should be soft.
- Proceed with the rest of the recipe while the squash is in the oven.
Cook chicken
- In a large, high-sided skillet, heat 2 tablespoons of olive oil. Add chicken seasoned generously with smoked paprika, dried oregano, salt and pepper.
- Cook the chicken on medium heat on both sides for about 10 or 20 minutes until the chicken is completely cooked through.
- Remove chicken from the skillet and slice it thinly.
Make a veggie mixture
- To the same, now empty, skillet (with juices from chicken), add fresh spinach, halved cherry tomatoes, and minced garlic. Cook the spinach on medium heat for about 5 or 10 minutes until it wilts.
- Add crumbled feta cheese and mix to combine.
- Season the veggie mixture with salt and pepper.
How to stuff spaghetti squash
- By this time, you have roasted the spaghetti squash for 30 or 40 minutes. Remove it from the oven and turn cooked squash halves cut sides up. Let it cool slightly.
- Divide the veggie mixture among the 4 halves and stuff the squash until the mixture is leveled. Top with the reheated cooked sliced chicken.
- When serving, top with fresh thyme.

This was an excellent healthy meal. I added some garlic powder to the meat as well, and also some balsamic dressing on it, or just put it on the table for people to put on themselves. Highly recommend to try this recipe
This recipe would serve 4 people. I only used one squash and adjusted the filling
Vida, thank you so much for taking the time to share your rave review on my website! I love that you added balsamic dressing as an option - perfect for Spring! 🙂
I’m looking forward to trying this. I’m wondering if the carb count is correct since an entire spaghetti squash has about 10 carb, and all the other ingredients have almost 0 carbs.
Marie, I looked at the break-down, the majority of carbs in this recipe comes from spaghetti squash (about 111 g), followed by tomatoes (about 14 g), then spinach (about 10 g), then feta cheese (about 10 g). A lot of it is fiber, of course. I am not a nutritionist, however, so I can't really provide any in-depth analysis on this. These numbers are really just estimates to give you a general idea.
The best way I have ever made spaghetti squash. This is in our once every 2 week rotation.
Wow, Cindy, I am so flattered! ❤️ Thank you for your rave review! ❤️
Love this recipe. Such great flavours. I added too much cheese ( I must follow recipes exactly!). Serving it with a green salad definitely helps to give freshness and crunchiness too. Very filling so lots left over for the next day. Can’t wait to try Julia’s other recipes.
Catherine, I am so glad you loved this recipe - thank you for such a kind comment! ❤️ I hope you like my other recipes as much as this one! 🙂
This recipe looks amazing! I'm going to try it for Christmas this year. It is my first time hosting! I'm excited!
Janice, this is a great recipe to make for the holidays! It makes a beautiful presentation, is healthy, and very tasty! Let me know how it turns out. ❤️❤️
What a wonderful way to serve squash. I happened across this recipe on FB and thought I would give it try. I had not cooked with this type of squash and found that I have been missing out on an excellent meal.
Sandy, I am so glad that you have a newfound appreciation for spaghetti squash! 🙂 It's such a tasty vegetable especially when it's dressed up the proper way. 🙂
Thank you for your review, and Happy Thanksgiving! 🙂
This looks so delicious! I haven’t made this recipe yet as I have a question. After roasting the halved squash do you spaghetti the squash with a fork prior to adding the mixture or just leave it as is?
Linda, I just roasted 2 spaghetti squash halves (hollowed out of all seeds), and then I stuffed the squash with the chicken mixture, without doing anything to the cooked spaghetti squash halves. Actually, if you scroll up above the recipe card, you will see the photo of the two empty roasted spaghetti squash halves (without any filling). I just stuffed those with the chicken mixture. Hope that clarifies it. 🙂
Question: is the spaghetti squash cooking time including the precooking in the microwave? Or should I reduce the about of time needed in the oven if softened in the microwave?
I just made this for dinner and it is delicious! I love the flavor combination of the squash, chicken, spinach and feta.
When I make this again, I will likely make this as a casserole for portion control and ease of reheating leftovers.
Gina, I am so glad you gave this recipe a try, and that it was a success! Thank you for your great review and the 5-star rating! ❤️
How do you serve? After baking, I use a fork & speghetti the squash. Do you do that with the mixture in it?
Since reheat and saving leftovers is in the opening description, I would probably only eat half a squash to keep carbs within MY daily count.
This looks awesome!!
How do you eat this? Just serve half per person and pig out? I’m all for it, but just want ti be sure before I go caveman on this
Fantastic recipe! Normally my hubby is NOT a spaghetti squash fan, but this was an A+ in his book. I substituted kale for the spinach because I have a garden full of kale. Worked perfectly! Next time I will pound out the boneless thighs a bit to give a more even cooking surface.
Kelly, thank you for your rave review! ❤️❤️ You're so lucky to have your own garden!
