  • 1 lb lean ground beef note 1
  • 4 cups spaghetti squash cooked & shredded; note 2
  • 1 jar marinara sauce 650 mL/ 22 oz; note 3
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • ½ teaspoon salt
  • ½ cup ricotta drain extra moisture
  • 1 cup mozzarella shredded
  • fresh basil to garnish


  • Cook beef - Heat oven to 425°F. Cook beef over medium heat in a deep 12-inch oven-safe skillet, breaking it up with a spatula. Cook until no pink remains - roughly 8 minutes. Use a paper towel to carefully blot up extra grease or fat from the pan.
  • Combine - Add the cooked spaghetti squash, marinara sauce, basil, oregano, and salt. Stir to combine (tongs make it easier to mix the spaghetti squash in with the sauce/beef). Cook over medium heat for 3 or so minutes, until heated through.
  • Bake - Dollop the ricotta over the skillet, then sprinkle with cheese. Place the skillet in the heated oven for 5 or so minutes, until sauce bubbles and cheese is melted.
  • Serve - Using oven mitts, carefully remove the skillet from the oven. Serve with fresh basil.
