Delicious Stuffed Spaghetti Squash Recipe

Ingredients

Servings:
4
  • 1 medium spaghetti squash
  • 1 cup cooked quinoa
  • 1 cup marinara sauce (preferably homemade or low-sugar)
  • 1 cup spinach (fresh or frozen)
  • 1 cup mozzarella cheese (shredded)
  • 1 teaspoon olive oil (for drizzling)
  • 1 teaspoon Italian seasoning
  • 1 cup parmesan cheese (grated)
  • 1 clove garlic (minced)
  • 1 teaspoon red pepper flakes (optional for heat)

Instructions

8 steps

  1. Preheat the Oven

    Preheat your oven to 400°F (200°C).

    This ensures even cooking of the squash.
  2. Prepare the Squash

    Cut the spaghetti squash in half lengthwise and scoop out the seeds.

    This will create the 'noodles' for stuffing.
  3. Roast the Squash

    Place the squash halves cut-side down on a baking sheet and roast for 30-40 minutes.

    Check for tenderness by piercing the skin with a fork.
  4. Prepare the Filling

    In a large mixing bowl, combine quinoa, marinara sauce, spinach, garlic, mozzarella, Italian seasoning, and red pepper flakes.

    Mix well to ensure even distribution of ingredients.
  5. Stuff the Squash

    Flip the roasted squash and fill each half with the quinoa mixture.

    Pack the filling tightly for maximum flavor.
  6. Add Cheese

    Top with grated parmesan cheese and a drizzle of olive oil.

    This will create a delicious, crispy topping.
  7. Bake Again

    Return to the oven and bake for an additional 15-20 minutes until cheese is bubbly.

    Keep an eye on the cheese to prevent burning.
  8. Serve

    Remove from the oven, let cool slightly, and serve warm.

    Garnish with fresh basil if desired.
