Description

This Cheesy Spaghetti Squash Casserole transforms roasted squash into a creamy, cheesy comfort dish that’s lighter and low-carb. With a blend of mozzarella, ricotta, and Parmesan, it’s rich yet wholesome, easy to customize, and perfect for both weeknight dinners and gatherings.


Ingredients

  • 1 medium spaghetti squash (about 2 to 3 pounds)
  • 2 cups shredded mozzarella cheese
  • 1 cup ricotta cheese
  • 1 cup grated Parmesan cheese
  • 1 large egg
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 cup marinara sauce (optional)
  • Fresh parsley, chopped (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Cut spaghetti squash in half lengthwise, scoop out seeds.
  2. Place squash halves cut-side down on a baking sheet. Roast for 30–35 minutes until tender.
  3. Cool slightly, then use a fork to scrape squash into strands. Transfer to a mixing bowl.
  4. Add mozzarella, ricotta, Parmesan, egg, garlic, Italian seasoning, salt, and pepper. Mix well.
  5. Grease a 9×13-inch baking dish. Spread a layer of marinara sauce if using.
  6. Spread squash mixture evenly into the dish. Top with additional mozzarella and Parmesan.
  7. Bake for 15–20 minutes until cheese is melted and golden. Let cool slightly.
  8. Garnish with parsley if desired and serve warm.

Notes

  • Add cooked ground meat or sautéed vegetables for variety.
  • Switch up cheeses for different flavors.
  • Use pesto or Alfredo instead of marinara for a twist.
  • Adjust baking time if doubling the recipe.
