Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
02 -
Boil a large pot of salted water. Cook the jumbo pasta shells just shy of al dente. Drain and set aside to prevent overcooking.
03 -
In a bowl, mix ricotta, half the mozzarella, Parmesan, beaten egg, Italian seasoning, salt, and pepper until smooth and fully combined.
04 -
Spread a layer of pasta sauce on the bottom of the prepared dish. Stuff each shell generously with the cheese mixture, then arrange them seam-side up in the dish.
05 -
Spoon the remaining pasta sauce over the shells. Sprinkle the remaining mozzarella and additional Parmesan on top, if desired. Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and golden.
06 -
Let the baked shells rest briefly out of the oven. Garnish with chopped fresh parsley before serving warm.
