Creamy, Comforting, and Guilt-Free! This Spaghetti Squash Chicken Alfredo is the perfect low-carb twist on a classic pasta dish. Made with wholesome ingredients, this recipe delivers all the rich flavors of traditional Alfredo without the heavy cream or added carbs!
This light and creamy comfort dish was super flavorful. I will be making this one on repeat! Spaghetti squash is also low in calories and contains several key vitamins and nutrients. This meal has it all!
I also love the idea of using the actual squash as the bowl! Dishes have become my chore in the house since I am forever cooking something. The squash bowl was also super fun for my kids when it came time for them to eat. When you pull the spaghetti out of the shell, it looks like real spaghetti.
You can really add spaghetti squash to a variety of dishes, like soups or stews. It can even be eaten raw if you desire.

Ingredients needed for this spaghetti squash meal

- garlic cloves - minced, enhance the overall flavor of the dish, infusing the meal with a strong, pungent garlic flavor.

Directions for skinny chicken alfredo spaghetti squash
Step-by-step directions to make this delicious, healthy dinner!
Step 1 - Preheat the oven to 350 degrees and spray a pan with cooking spray. Lay your chicken on the pan and season with salt and pepper. Bake for 20 - 25 minutes.
Step 2 - Use a large knife to cut your spaghetti squash in half lengthwise. Lightly coat the inside with cooking spray and place cut-side down on a separate baking tray. Bake for 30 minutes.
Step 3 - Meanwhile, heat olive oil in a large cast-iron skillet over medium heat. Add garlic and cook until fragrant, about 2-3 minutes.
Step 4 - Whisk in flour and cook for 3 minutes. Then, gradually whisk in milk until it's smooth. Simmer until thickened, about 5 minutes.
Step 5 - Whisk in lemon juice, Parmesan cheese, salt, and pepper.
Step 6 - Once the chicken is done, shred it with 2 forks and add it to the sauce, stirring to combine.
Step 7 - Once spaghetti squash is done, remove it from the oven and turn it over using a large spatula, as the squash will be very hot. Scrape out the seeds and discard them. Use a fork and scrape out the squash so it makes spaghetti strands, and add them to the chicken mixture, stirring to combine.
Step 8 - Fill empty squash boats with the chicken alfredo mixture and then top with the shredded mozzarella and return to the oven for 10 more minutes. Broil for 2 minutes at the end until the cheese is golden, then sprinkle with fresh parsley and serve.
Substitutions and Variations
Whole Wheat Flour - you can also use all-purpose flour as a substitute for whole wheat.
Milk - I usually use 2%, but you can also make this dish using heavy cream, 1%, whole, or almond milk. You can also try plain Greek yogurt or light cream cheese to give it an even creamier texture.
Lemon Juice - I prefer freshly squeezed lemon juice, but you can also use bottled lemon juice.
Tips and FAQ's
Yes, store the cooked squash and sauce separately in air-tight containers. When you're ready to serve, combine and reheat for the best texture.
You can store this dish for up to 4 days in an air-tight container.
You can pair this with a fresh green salad or my super-easy Air Fryer Broccoli recipe.
Don't over-roast the squash! You want it tender, but not mushy!
