  • 48 oz. RAGÚ® Pasta sauce
  • 1.5 lbs. ground beef
  • ½ cup diced white onion
  • 1 minced garlic clove
  • ¼ tsp. salt
  • 1 tsp.dried oregano
  • 1 tsp. dried basil
  • 1 lb. spaghetti noodles see below for cooking instructions, these don't get cooked or added until after the sauce cooks for 6 hours

Cheese topping after sauce cooks:

  • 4 ounces cream cheese 1/2 cup
  • 1 cup ricotta
  • ¼ tsp. salt
  • 2 cups shredded mozzarella cheese


  • Pour the jars of sauce in to the slow cooker. In a large skillet set over medium-high heat, brown the meat and onions together. After the meat is browned add the garlic, cook for a minute a longer. Drain the fat. Add the salt, oregano and basil and stir. Pour the meat onto the sauce in the slow cooker and stir.
  • Cover and cook on LOW for 6 hours without opening the lid during the cooking time.
  • After the cooking time is up, cook the noodles as directed on the package in boiling water on the stove-top. I cooked my noodles for exactly 8 minutes after adding them to the boiling water. The noodles will cook a bit more after adding them to the slow cooker.
  • Drain the noodles and add them to the meat sauce in the slow cooker. Stir, then flatten the noodles in an even layer.
  • In a small bowl combine the cream cheese, ricotta and salt. The cream cheese will be in small chunks, but that is fine.
  • Dollop the cream cheese/ricotta mixture over the spaghetti, then use a spatula to even it out over the spaghetti. Add the mozzarella cheese.
  • Cover and cook for an extra 20 minutes on LOW.
  • Serve and enjoy!
