Ingredients
For the Spaghetti Squash
- 2 medium spaghetti squash (about 3 pounds each)
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
For the Filling
- 1 pound boneless, skinless chicken breasts, cut into small cubes
- 3 tablespoons butter
- 6 cloves garlic, minced (about 2 tablespoons)
- 1 small onion, finely diced
- 8 ounces fresh spinach
- 1 cup chicken broth (low-sodium preferred)
- 4 ounces cream cheese, softened
- 1/2 cup plain Greek yogurt
- 1 cup freshly grated parmesan cheese, plus extra for topping
- 1/2 teaspoon dried thyme
- 1/4 teaspoon red pepper flakes (optional)
- 1/4 cup chopped fresh parsley, divided
How to Make Garlic Parmesan Stuffed Spaghetti Squash with Chicken and Spinach
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). This ensures that your spaghetti squash bakes evenly.
Step 2: Prepare the Spaghetti Squash
Cut each spaghetti squash in half lengthwise. Remove the seeds using a spoon. Brush the cut sides with olive oil. Season them with salt, pepper, and garlic powder. Place the squash cut-side down on a baking sheet.
Step 3: Bake the Squash
Bake in the preheated oven for 30-35 minutes until tender. You can check if it’s done by piercing it with a fork; it should be easily pierced.
Step 4: Cook the Chicken
While the squash is baking, heat 1 tablespoon of butter in a skillet over medium heat. Add the chicken pieces and cook until golden brown. Once cooked, set aside.
Step 5: Sauté Vegetables
In the same skillet, add another tablespoon of butter. Sauté the diced onion until translucent. Then add minced garlic; cook for about 30 seconds until fragrant. Add fresh spinach next and cook until wilted.
Step 6: Create the Creamy Mixture
Pour in chicken broth and bring it to a simmer. Add cream cheese, Greek yogurt, parmesan cheese, thyme, and optional red pepper flakes. Mix well until creamy. Return cooked chicken to this mixture along with half of the chopped parsley.
Step 7: Mix with Spaghetti Strands
Once your squash is cooked, use a fork to scrape out strands from each half carefully. Combine some of these strands with your creamy chicken mixture.
Step 8: Stuff the Squash Halves
Fill each spaghetti squash half with the remaining creamy mixture. Top generously with additional parmesan cheese.
Step 9: Final Bake
Return stuffed squash halves to the oven and bake for an additional 10-15 minutes until cheese is melted and golden brown.
Step 10: Garnish & Serve
Allow to cool for about 5 minutes before serving. Garnish with remaining chopped parsley for added freshness.

Common Mistakes to Avoid
When making Garlic Parmesan Stuffed Spaghetti Squash with Chicken and Spinach, it’s easy to make some common mistakes. Here are a few to watch out for:
- Skipping the seasoning: Not seasoning the spaghetti squash before baking can lead to bland flavors. Always brush with olive oil and season generously.
- Overcooking the chicken: Cooking the chicken too long may dry it out. Cook just until golden brown and tender for the best texture.
- Not using fresh ingredients: Using stale spices or old vegetables can diminish flavor. Always opt for fresh garlic, spinach, and herbs for a vibrant taste.
- Ignoring cooking times: Baking the squash too long can turn it mushy. Check for doneness at 30 minutes and adjust as needed.
- Not mixing well: Failing to combine the creamy filling thoroughly can result in uneven flavors. Make sure to mix the filling until smooth before stuffing.
