  • Baking Sheet


For the squash

  • 1 small spaghetti squash (about 4 pounds)
  • 1/2 tsp olive oil
  • Salt & pepper to season

For the sauce

  • 1 lb ground beef
  • 1 tsp salt divided
  • 15 oz canned chopped tomatoes
  • 2 tbsp tomato paste
  • 1 clove garlic minced
  • 1 tsp Italian herbs
  • 1/4 tsp oregano
  • 1/4 tsp ground black pepper
  • 1/2 cup mozzarella cheese shredded


  • Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.
  • Cut the spaghetti squash in half lengthwise. Rub olive oil on the flesh and season with salt and pepper. Place the squash halves, flesh-side down on the baking sheet. Poke the skin a few times with a fork. Bake for 30 minutes.
  • Meanwhile, add 1/2 tsp of salt to the ground beef and mix well. Form 1 ½” round meatballs. Brown the meatballs in a medium skillet over high heat, about 8 minutes.
  • Turn the heat to medium and add the tomatoes, tomato paste, garlic, herbs and remaining salt to the skillet. Stir well. Simmer for 15-20 minutes, while the spaghetti squash cooks. If the sauce is too thick, add 1-2 tbsp water to loosen it up.
  • When the squash is done, remove from the oven. Using a fork, gently scrap the squash loose from the skin and fluff into strands.
  • Add half the meatballs and sauce to each squash half. Top with mozzarella cheese. Return the squash to the oven and cook for an additional 8-10 minutes, until the tops are melted and bubbly.


  • The carb count of this dish assumes a squash size that results in 5 cups of cooked squash (about a 4 pound squash).
