  • 1 large spaghetti squash
  • 1 lb lean ground turkey
  • 2 cups marinara sauce
  • 1 cup part-skim ricotta cheese
  • 1 cup shredded mozzarella cheese
  • 2 cloves garlic, minced
  • 1 small onion, diced
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste
  • Fresh basil or parsley for garnish (optional)


1. Preheat the Oven:

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

2. Prepare the Spaghetti Squash:

  • Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds and pulp with a spoon.
  • Place the squash halves, cut side down, on a baking sheet lined with parchment paper.
  • Bake in the preheated oven for 40-45 minutes, or until the squash is tender when pierced with a fork.
  • Remove the squash from the oven and let it cool slightly.

3. Cook the Turkey Meat Sauce:

  • While the squash is baking, heat a skillet over medium heat and add a drizzle of olive oil.
  • Add the diced onion and minced garlic to the skillet and sauté until softened and fragrant, about 2-3 minutes.
  • Add the lean ground turkey to the skillet and cook until browned and cooked through, breaking it apart with a spoon as it cooks.
  • Pour in the marinara sauce and Italian seasoning, stirring to combine. Let the sauce simmer for 5-7 minutes, then remove it from the heat.

4. Prepare the Ricotta Cheese Mixture:

  • In a small bowl, combine the ricotta cheese with salt and pepper to taste. Mix until well combined.

5. Assemble the Lasagna:

  • Once the spaghetti squash has cooled slightly, use a fork to scrape the strands of squash from the skin, creating “noodles.”
  • In a baking dish, spread a thin layer of the turkey meat sauce on the bottom.
  • Arrange a layer of spaghetti squash noodles on top of the sauce.
  • Dollop spoonfuls of the ricotta cheese mixture over the squash noodles, spreading it out evenly.
  • Spoon more of the turkey meat sauce over the ricotta cheese layer.
  • Repeat the layers until all the ingredients are used, finishing with a layer of turkey meat sauce on top.

6. Bake the Lasagna:

  • Sprinkle the shredded mozzarella cheese evenly over the top layer of meat sauce.
  • Cover the baking dish with foil and bake in the preheated oven for 25-30 minutes.
  • Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly and the edges are golden brown.

7. Serve and Garnish:

  • Once the lasagna is cooked through and the cheese is golden and bubbly, remove it from the oven.
  • Let it cool for a few minutes before slicing into portions.
  • Garnish with fresh basil or parsley if desired, and serve hot.

8. Enjoy!

  • Serve the Spaghetti Squash Lasagna as a delicious and nutritious meal option for the whole family to enjoy.
