Instructions

  1. Preheat oven to 425°F. Cut the squash in half lengthwise and remove the seeds. Brush the flesh with 1 teaspoon oil. Place them cut side down on a baking sheet lined with parchment paper. Roast in the oven until tender, about 40 minutes. Remove from oven and cool. When the squash is cooled, scrape the flesh with a fork so that it forms spaghetti-like strands. You should have a total of about 6 cups total.
  2. Meanwhile, make the sauce by heating 2 teaspoons oil in a large sauté pan over medium heat. Add the onion and garlic and cook 4-5 minutes until partially softened. Stir in the tomatoes, Italian seasoning, red pepper flakes, ½ teaspoon salt and ¼ teaspoon pepper. Simmer the sauce for 15-20 minutes until thickened.
  3. Mix the ricotta, egg, spinach, ½ cup mozzarella cheese, 1 teaspoon salt and ¼ teaspoon pepper together in a large bowl. Squeeze all of the liquid from the spaghetti squash and add it to the bowl (the squash releases a lot of water as it cooks so make sure to squeeze it well). Stir to combine all of the ingredients.
  4. Turn the heat on the oven down to 375°F. To assemble the lasagna, spread about 1 ½ cups of the sauce on the bottom of an 8x11-inch baking dish. Add the squash mixture on top and spread it out evenly. Spread the remaining tomato sauce over the top of the squash and sprinkle the remaining 1 cup mozzarella and Parmigiano cheese on top.
  5. Bake in the oven 35-40 minutes until bubbly and cheese is melted. Garnish with parsley. Let stand 10 minutes before cutting and serving.
