Ingredients

• 1 large spaghetti squash
• 1 tablespoon olive oil
• 1 medium yellow onion
• 3 cloves garlic cloves
• 2 cups low-fat marinara sauce
• 3 cups baby spinach
• 1 cup part-skim mozzarella cheese
• 0.25 cup grated Parmesan cheese
• 1 teaspoon Italian seasoning
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 2 tablespoons fresh basil leaves (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Cut the spaghetti squash in half lengthwise and remove the seeds. Place the halves cut side down on a baking sheet lined with parchment paper.

Step 3

Bake the spaghetti squash for 30-40 minutes, or until the flesh is tender and easily shredded with a fork. Remove from the oven and let it cool slightly.

Step 4

While the squash is baking, heat the olive oil in a large skillet over medium heat. Dice the onion and mince the garlic, then sauté them in the olive oil until softened, about 5 minutes.

Step 5

Add the marinara sauce, Italian seasoning, salt, and pepper to the skillet, and stir to combine. Let the mixture simmer for 5 minutes.

Step 6

Stir in the baby spinach and cook until wilted, about 2 minutes.

Step 7

Once the spaghetti squash is cool enough to handle, use a fork to scrape out the strands of squash into a large bowl. Add the marinara and spinach mixture to the bowl and mix thoroughly.

Step 8

Lightly grease a 9x13-inch casserole dish. Spread the squash mixture evenly in the dish.

Step 9

Sprinkle the mozzarella cheese and Parmesan cheese over the top of the casserole.

Step 10

Bake in the preheated oven for 20 minutes, or until the cheese is melted and bubbly.

Step 11

If desired, turn on the broiler for 2-3 minutes at the end to brown the top slightly.

Step 12

Remove from the oven and let the casserole rest for 5 minutes before serving.

Step 13

Garnish with fresh basil leaves, if desired, and serve warm.
