Roasting garlic alongside the spaghetti squash makes double use of the oven time, and adds double the flavor. This spaghetti squash is great on its own, or as a side dish to any protein.


  • 3 tablespoons olive oil, divided, or as needed
  • 1 (2 pound) spaghetti squash, halved and seeded
  • ¼ teaspoon kosher salt, or to taste
  • ⅛ teaspoon freshly ground black pepper, or to taste
  • 4 cloves garlic, unpeeled
  • 1 teaspoon onion powder
  • ½ teaspoon dried basil
  • ½ teaspoon dried oregano
  • ½ teaspoon dried parsley
  • 1 cup chopped fresh spinach
  • 6 tablespoons shredded mozzarella cheese, divided
  • 6 tablespoons grated Parmesan cheese, divided


Preheat the oven to 350 degrees F (175 degrees C).

Drizzle olive oil over the cut side of the spaghetti squash. Season with salt and black pepper. Place cut-side down on a baking sheet. Place unpeeled garlic on a piece of aluminum foil. Drizzle with olive oil. Wrap aluminum foil around garlic, and place onto baking sheet next to the squash.

Bake in the preheated oven until squash is tender and easily pierced with a fork, 40 to 45 minutes. Allow squash and garlic to rest until cool enough to handle. Leave the oven on.

Peel garlic and squeeze cloves into a large bowl. Smash with a fork until smooth. Add 1 tablespoon olive oil, onion powder, basil, oregano, and parsley. Mix into a paste.

Use a fork to scrape out spaghetti squash strands into the bowl, reserving the shells. Toss spaghetti squash strands with the garlic paste until thoroughly coated. Mix in spinach, 1/4 cup mozzarella cheese, and 1/4 cup Parmesan cheese; toss to combine. Season with salt and pepper.

Fill each reserved spaghetti squash shell evenly with the filling. Sprinkle remaining mozzarella and Parmesan over the top. Return the filled shells to the baking sheet.

Bake until cheeses melt, 7 to 10 minutes. Turn on broiler and broil until cheeses begin to brown and bubble, 3 to 5 minutes. Serve immediately.
