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 temperature ensures that the spaghetti squash becomes tender while roasting.
Step 2: Prepare the Spaghetti Squash
Cut the spaghetti squash in half lengthwise and remove the seeds. Brush the cut sides with olive oil. Season them with salt, pepper, and garlic powder.
Step 3: Roast the Squash
Place the squash halves cut-side down on a baking sheet. Bake for 30-35 minutes or until they are tender. This will create perfect strands to mix with your filling.
Step 4: Cook the Chicken
While the squash is baking, heat 1 tablespoon of butter in a skillet over medium heat. Add the cubed chicken pieces and cook until golden brown. Once cooked, set aside.
Step 5: Sauté Vegetables
In the same skillet, add remaining butter. Cook diced onion until translucent. Then add minced garlic and sauté for about 30 seconds until fragrant.
Step 6: Add Spinach
Add fresh spinach to the skillet. Cook until wilted. Pour in chicken broth and bring it to a gentle simmer.
Step 7: Combine Filling Ingredients
Stir in cream cheese, Greek yogurt, parmesan cheese, dried thyme, and optional red pepper flakes. Return cooked chicken to skillet and mix everything well. Stir in half of chopped parsley and let it simmer for another 2-3 minutes.
Step 8: Assemble the Dish
Once your spaghetti squash is roasted, use a fork to create spaghetti-like strands within each half. Mix some of this creamy mixture with those strands before filling each half generously with the remaining chicken mixture.
Step 9: Bake Again
Top each filled squash half with additional parmesan cheese. Return them to bake for another 10-15 minutes until cheese is melted and golden brown.
Step 10: Serve
Let cool for about 5 minutes before garnishing with remaining parsley. Enjoy your delicious Garlic Parmesan Stuffed Spaghetti Squash with Chicken and Spinach!
