Jumbo pasta shells are stuffed with a beefy cheesy mixture and smothered in marinara sauce.


  • 1 pound lean ground beef
  • 1 tsp kosher salt
  • 1 tsp garlic powder
  • 1 tsp black pepper
  • 1 tsp dried basil
  • 1 tsp onion powder
  • 1 tsp dried parsley
  • 1/2 tsp dried oregano
  • 2 cups cottage or ricotta cheese
  • 1 egg
  • 1 cup grated mozzarella cheese
  • 1/2 cup shredded parmesan cheese
  • 1 (12 oz) box jumbo pasta shells (has about 42 shells in it)
  • 2 cups water
  • 1 (26 oz jar or can) marinara sauce


  1. In a pan over medium high heat brown the ground beef for about 5 minutes. Add in the salt, garlic powder, pepper, basil, onion powder, parsley and oregano. Stir. 
  2. Add cottage/ricotta cheese, egg, mozzarella and parmesan into the bowl with the meat. Stir to combine. 
  3. Use your fingers to stuff the meat mixture into the pasta shells. Some shells will be easier to stuff than others. 
  4. Place each of the shells into the bottom of your slow cooker. Pour 2 cups water over the shells and then pour the marinara sauce over the top evenly.
  5. Cover and cook on low for 4 hours, or until pasta is tender. Serve and enjoy!
