How to Make Chicken Alfredo Spaghetti Squash
-
Preheat the oven to 375°F. Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the squash cut side down on a lined baking sheet and bake for 30-40 minutes. Look for dark and glossy skin and fork-tender strands.
-
Cool the spaghetti squash. Once finished baking, remove from the oven and let it sit for about 15 minutes until it’s cool enough to handle.
-
Sauté garlic. In a large skillet set over medium heat, add oil and minced garlic. Sauté for 1-2 minutes, stirring frequently until fragrant and slightly golden.
-
Whisk together the sauce. Pour in the chicken broth, cornstarch, salt, and pepper. Whisk until smooth, then bring to a boil. Reduce the heat to low and simmer for about 1-2 minutes until slightly thickened.
-
Add the cheesy goodness. Remove the skillet from the heat and stir in the Parmesan cheese until melted and smooth. Then, add Greek yogurt and mix until silky. Finally, fold in the shredded chicken.
-
Scrape the spaghetti squash. Use a fork to gently separate the strands of the squash, leaving them inside the shells. Top each half with the cheesy chicken Alfredo filling, ensuring it settles well.
-
Top with mozzarella. Sprinkle 2 tablespoons of mozzarella cheese on each filled shell, then place them in a baking dish. Bake for 10-12 minutes, then broil until golden and bubbly.
-
Serve hot. Before serving, give the squash a light stir with the sauce for even distribution, and enjoy this comforting dish!

Expert Tips for Chicken Alfredo Spaghetti Squash
- Choose Perfect Squash: Look for a medium-sized, firm spaghetti squash that’s heavy for its size; this ensures tender strands with the right flavor.
