Bring a large pot of salted water to a boil and cook the pasta shells for around 8 minutes. Drain and drizzle olive oil to avoid the shells from sticking to each other.
In a large mixing, add the ground beef, Italian sausage, diced onion, parsley, breadcrumbs, 1/4 cup grated parmesan, garlic and AP seasoning.
Mix everything with your hands, making sure all the ingredients are fully incorporated.
Take a scoop of the filling mix and carefully stuff it inside the shell. Add a small cube of mozzarella cheese to the filling and cover with the meat.
Add a thin layer of marinara sauce to the bottom of a cast iron skillet
Arrange the stuffed shells in the skillet, one next to the other, until full. Cover the top with more marinara sauce.
Finish it off with shredded mozzarella , the remaining cubed mozzarella and grated parmesan.
Preheat the grill to 375 degrees Fahrenheit. Cover the full cast iron skillet with aluminum foil and place it on the grill for 20 minutes.
Remove the foil and continue cooking uncovered, for 20-30 minutes, or until the internal temperate of the filling reaches 145 degrees.
Remove it from the grill and let it rest 5-10 minutes before serving. Enjoy!
Notes
Don’t overcook the pasta before stuffing
Use whole milk cheese for creaminess and the extra cheese pull
Let rest before serving to set the filling
Use a cast iron skillet for even heat and presentation
