  • 1 Pound Ground Beef
  • 1 Medium Onion - diced

  • 32 Ounces Crushed Tomatoes 
  • 1 Teaspoon Fresh Basil
  • 1 Teaspoon Italian Seasoning
  • 3/4 Teaspoon Salt
  • 1/2 Teaspoon Pepper

  1. Preheat the oven to 350 degrees. Grease a 9x13" baking dish with cooking spray.
  2. In a large pot, add ground beef over medium heat. Cook for 5-7 minutes and break up with a wooden spoon or meat chopper while cooking.
  3. Add in the onion and garlic and cook for another 5-7 minutes, until the ground beef is fully cooked and the onions have softened.
  4. Add in the tomatoes and seasoning. Bring to a simmer over medium-low heat.
  5. Cook spaghetti in a large pot with heavily salted water for 6-7 minutes. Do not cook fully to al dente as it will continue to cook in the oven.
  6. Strain the pasta and add to the meat sauce. Toss all together.
  7. Pour into the baking dish and top with the fresh mozzarella. Bake for 25 minutes or until hot and bubbly around the sides.
  8. Remove and top with freshly grated parmesan cheese and let sit 10 minutes before serving.
