Instructions

  • Preheat your oven to 400°F. Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle lightly with olive oil and season with salt and pepper. Place cut-side down on a baking sheet and roast for 35-40 minutes, until fork-tender.
  • Once cool enough to handle, use a fork to scrape out the strands and set aside on a paper towel to soak up the excess moisture.
  • While the squash roasts, heat a large skillet over medium heat. Add the Italian sausage and cook, breaking it up, until browned and fully cooked.
  • Add the diced onion, red bell pepper, and mushrooms. Sauté for 5-7 minutes, until softened. Stir in the Italian seasoning, garlic powder, and one container of pizza sauce. Simmer on low until the spaghetti squash is done, then remove from the heat.
  • Reduce oven temperature to 375°F.
  • Lightly grease a large baking dish. Add the spaghetti squash strands and spread them evenly across the bottom. Pour in the other container of pizza sauce and toss gently to combine.
  • Layer the cooked sausage and veggie mixture evenly over the squash. Add mozzarella cheese on top, then finish with a layer of pepperoni.
  • Place uncovered in the oven and bake for 15 minutes, and finish with a 1-2 minute broil until the cheese is melted, bubbly, and lightly golden.
  • Let cool for a few minutes, then slice and serve. Optional but highly encouraged: extra red pepper flakes, fresh basil, or a drizzle of hot honey.
