Ingredients
  

  • 2 medium spaghetti squash about 3 pounds each
  • 3 tablespoons olive oil divided
  • 1 medium onion finely diced
  • 4 garlic cloves minced
  • 1 teaspoon red pepper flakes adjust to taste for heat level
  • 1 can 28 oz crushed tomatoes
  • 2 tablespoons tomato paste
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil or 2 tablespoons fresh, chopped
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • 1 cup freshly grated parmesan cheese divided
  • ¼ cup fresh parsley chopped (for garnish)

Instructions
 

  • Prepare the squash: Preheat your oven to 400°F (200°C). Carefully cut each spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut sides with 1 tablespoon of olive oil and season with salt and pepper.
  • Roast the squash: Place the squash halves cut-side down on a baking sheet lined with parchment paper. Bake for 35-45 minutes, or until the flesh is tender and can be easily scraped with a fork.
  • Prepare the sauce: While the squash is roasting, heat the remaining 2 tablespoons of olive oil in a large skillet over medium heat. Add the diced onion and cook for 4-5 minutes until softened and translucent.
  • Add aromatics: Stir in the minced garlic and red pepper flakes, cooking for about 30 seconds until fragrant, being careful not to burn the garlic.
  • Develop the sauce: Add crushed tomatoes, tomato paste, dried oregano, basil, salt, and pepper to the skillet. Bring to a simmer, then reduce heat to medium-low and cook for 10-15 minutes, stirring occasionally, until the sauce thickens slightly.
  • Fluff the squash: When the squash is done, flip them over (careful—they’re hot!) and use a fork to gently scrape the insides, creating spaghetti-like strands. Leave the strands in the squash shells, forming a bowl.
  • Assemble the dish: Spoon the spicy tomato sauce evenly over each squash half, then sprinkle with ¾ cup of the parmesan cheese, dividing it equally among the four halves.
  • Broil to finish: Switch your oven to broil. Place the filled squash halves under the broiler for 2-3 minutes, just until the cheese melts and begins to bubble and brown slightly.
  • Garnish and serve: Remove from the oven, sprinkle with remaining parmesan cheese and fresh parsley. Serve immediately while hot.

Notes

  • To make this dish ahead, roast the squash and prepare the sauce up to 2 days in advance. Store separately in the refrigerator, then reheat the sauce, assemble, and broil when ready to serve.
  • For a meatier version, brown 1/2 pound of Italian sausage or ground turkey with the onions before adding the garlic.
  • The squash can be difficult to cut when raw – microwave it for 5 minutes first to soften the exterior slightly.
  • Don’t throw away those seeds! Clean them, toss with olive oil and salt, and roast alongside the squash for a crispy snack.
  • Make sure to scrape the squash strands gently to maintain their integrity and prevent them from becoming mushy.
