Equipment

  • Fork
  • Baking Sheet
  • Large knife
  • Grapefruit spoon (or regular spoon)
  • Large skillet
  • Mixing spoon
  • Oven

Ingredients
  

  • 1 large spaghetti squash 3-4 pounds
  • 1 tablespoon olive oil
  • Salt to taste
  • Pepper to taste
  • 1 pound Italian sausage, removed from casings
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 5 ounces fresh spinach, roughly chopped
  • ½ cup ricotta cheese
  • ¼ cup grated Parmesan cheese
  • 1 teaspoon dried oregano
  • ½ teaspoon red pepper flakes optional
  • Fresh basil, chopped optional
  • Extra Parmesan cheese optional
  • Mozzarella cheese, shredded optional

Instructions
 

  • Preheat oven to 375°F (190°C). Poke holes all over the spaghetti squash with a fork.
  • Bake the whole squash for 30-45 minutes, or microwave for 5-7 minutes, rotating halfway through. Let cool slightly.
  • Preheat oven to 400°F (200°C).
  • Carefully cut the squash in half lengthwise and scoop out the seeds and stringy bits.
  • Drizzle the cut sides of the squash with olive oil, then season with salt and pepper.
  • Place the squash halves cut-side up on a baking sheet and roast for 30-40 minutes, or until the flesh is easily pierced with a fork.
  • While the squash is roasting, brown the Italian sausage in a large skillet over medium heat, breaking it up with a spoon. Drain off any excess grease.
  • Add the chopped onion and cook until softened, about 5 minutes. Then, add the minced garlic and cook for another minute until fragrant.
  • Stir in the chopped spinach and cook until it wilts, about 2-3 minutes.
  • Add the diced tomatoes (undrained), ricotta cheese, Parmesan cheese, oregano, and red pepper flakes (if using). Season with salt and pepper to taste. Simmer for 5-10 minutes, allowing the flavors to meld together.
  • Once the spaghetti squash is cooked and cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands, leaving about 1/2 inch of squash intact along the edges.
  • Gently stir the spaghetti squash strands into the sausage and spinach mixture in the skillet.
  • Spoon the filling back into the spaghetti squash 'boats,' mounding it slightly on top.
  • If desired, sprinkle the tops of the stuffed squash boats with shredded mozzarella cheese or extra Parmesan cheese.
  • Bake in a preheated oven at 350°F (175°C) for 10-15 minutes, or until the cheese is melted and bubbly (if using).
  • Remove the stuffed spaghetti squash boats from the oven and let them cool slightly before serving.
  • Garnish with fresh basil, if desired. Serve immediately and enjoy.

Notes

Pre-roasting the squash makes scooping easier. Get creative with the filling! Use ground beef, turkey, or lentils. For make-ahead, roast squash and prepare filling ahead, storing separately. Stuffed squash boats can be frozen for up to 2 months; thaw overnight before reheating.
