Ingredients

For the Cheese Mixture
- 2 ounces cream cheese
- 3 ounces whole-milk, low-moisture mozzarella cheese, shredded (about 3/4 cup)
- 2 ounces Parmesan cheese, grated (about 1 cup), divided
For the Spaghetti Squash
- 2 medium spaghetti squash (about 5 pounds total)
- 1 tablespoon olive oil
- 3/4 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
For Garnish
- 2 tablespoons chopped fresh parsley leaves, plus more for garnish
- 1/2 teaspoon garlic powder
How to Make Cheesy Garlic Parmesan Spaghetti Squash
Step 1: Preheat the Oven
Arrange a rack in the middle of the oven and heat it to 400°F. Line a rimmed baking sheet with aluminum foil or parchment paper; set aside. Place 2 ounces of cream cheese in a large bowl and let sit at room temperature while the oven heats to soften.
Step 2: Prepare the Spaghetti Squash
Cut 2 spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut sides of the squash with 1 tablespoon olive oil and season with 3/4 teaspoon kosher salt and 1/4 teaspoon ground black pepper. Arrange the squash cut-side down on the baking sheet. Roast until soft when poked with a fork and browned on the skin, about 40 minutes.
Step 3: Mix the Cheese Filling
Shred 3 ounces of mozzarella cheese (about 3/4 cup) and grate 2 ounces of Parmesan cheese (1 cup). Chop until you have 2 tablespoons fresh parsley leaves; reserve some for garnish. Add mozzarella, 3/4 cup of Parmesan (set aside remaining 1/4 cup), parsley, and garlic powder to cream cheese. Stir well with a rubber spatula to combine.
Step 4: Combine Squash with Cheese Mixture
Remove the baking sheet from the oven. Flip each squash half over and use a fork to shred its insides, leaving about 1/2-inch unshredded in each shell. Transfer shredded squash to cream cheese mixture; toss well to combine. Evenly divide filling between each half and sprinkle remaining Parmesan on top.
Step 5: Bake Until Golden Brown
Bake until cheese melts, about 8 to 10 minutes. Turn on broil setting and broil until browned and bubbly, about 2 to 3 minutes more. Garnish with additional parsley before serving hot.
