Ingredients
  

  • 1 large spaghetti squash
  • 1 lb ground turkey or beef
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 cup marinara sauce
  • 1 cup ricotta cheese
  • 1 cup shredded mozzarella
  • 1/2 cup grated Parmesan
  • 2 tablespoons olive oil
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

Instructions
 

  • Preheat oven to 400°F (200°C). Slice squash in half, scoop seeds, and drizzle with olive oil. Roast 35–40 minutes until tender.
  • Scrape squash flesh with a fork to form spaghetti-like strands. Set aside.
  • Cook ground turkey or beef with onion and garlic until browned. Add marinara, seasoning, salt, and pepper.
  • In a baking dish, layer squash strands, meat sauce, ricotta, mozzarella, and Parmesan.
  • Bake at 375°F (190°C) for 20 minutes until bubbly and golden.

Notes

  • Squash strands should be fork-tender, not mushy.
  • Marinara sauce enhances flavor depth.
  • Ricotta adds creaminess to the casserole.
  • Use lean ground meat for a lighter dish.
  • Fresh basil makes a great garnish.
