Ingredients

• 1 teaspoon onion powder
• 1 cup chopped fresh spinach
• 6 tablespoons grated Parmesan cheese, divided
• 3 tablespoons olive oil, divided, or as needed
• 1 (2 pound) spaghetti squash, halved and seeded
• 4 cloves garlic, unpeeled
• 6 tablespoons shredded mozzarella cheese, divided

Recipe Instructions

Step 1

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

Step 2

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

Step 3

Fill squash shells evenly with spinach filling; sprinkle remaining 2 tablespoons each mozzarella and Parmesan over top. Place filled shells on the baking sheet.

Step 4

Drizzle about 1 tablespoon olive oil over cut sides spaghetti squash; season with salt and black pepper. Place squash on a baking sheet, cut-sides down. Place unpeeled garlic on a piece of aluminum foil; drizzle with about 1 tablespoon olive oil. Wrap aluminum foil around garlic; place onto baking sheet next to squash.

Step 5

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

Step 6

Scrape out squash strands into the same bowl using a fork; reserve shells. Toss squash strands with garlic paste until thoroughly coated. Stir in spinach, ¼ cup mozzarella cheese, and ¼ cup Parmesan cheese; toss to combine. Season with salt and black pepper.

Step 7

Bake in the preheated oven until cheeses melt, 7 to 10 minutes. Turn on the broiler and broil until cheeses begin to brown and bubble, 3 to 5 minutes.
