Equipment

  • Cutting board
  • Chef's knife
  • Deep skillet
  • Wooden spoon
  • Rimmed sheet pan
  • 1/2 cup measure
  • Teaspoon measure
  • Tablespoon measure

Ingredients

  • 1 spaghetti squash, halved with some of the insides scooped out to form a well Reserve any of the extra insides to stir into the filling.
  • 2 tablespoons garlic herb butter, melted
  • 1 tablespoon olive oil
  • 1/2 of a large onion, diced
  • 2 cloves garlic, minced
  • 3/4 pound sweet Italian sausage, casings removed
  • 1 cup marinara sauce See notes for recipe, or use a jarred version.
  • 1/2 cup whole milk ricotta
  • 2 teaspoons chopped fresh oregano
  • Salt and pepper to taste
  • 6 ounces shredded mozzarella

Instructions

  • Preheat oven to 400 degrees Fahrenheit. Place spaghetti
    squash halves on a rimmed baking sheet facing up. Brush the garlic herb butter
    evenly over each of the spaghetti squash halves. Roast in the preheated oven
    for 30-45 minutes, or until the squash is fork-tender.
  • While the squash is cooking, prepare the filling. Place a deep skillet on the stove over medium heat and add the olive oil. Once the oil is heated, add the onions and sauté for a few minutes, until fragrant and translucent, then add the garlic and stir to combine. Let cook for a minute or two and then add the Italian sausage and cook until browned.
  • Add in the marinara, ricotta and oregano and stir to combine. Let the mixture heat up and come to a gentle bubble, then turn off the heat.
  • When your squash is fork-tender and you’ve pulled it out of the oven, lower the oven heat to 350 degrees. Then, carefully scoop the filling into each of the halves and sprinkle with mozzarella.
  • Return the squash to the 350-degree oven and cook for 10-15 minutes, then turn on the broiler and cook for another 4 or so minutes, until the cheese on top is browned and bubbly. Remove from the oven and let cool slightly before cutting the halves in half and serving.
