Step 1

Preheat the oven to 350°F.

Step 2

In a saucepan of boiling salted water cook shells al dente. Drain.

Step 3

Meanwhile heat marinara sauce over low-medium heat.

Step 4

In a bowl mix the ricotta with 1 1/2 cups mozzarella, parmesan, egg, and basil. Salt and pepper. Stuff the shells with the cheese preparation.

Step 5

Pour two-thirds of the marinara sauce into a 13 x 9" baking dish. Place the stuffed shells in the dish. Cover with remaining sauce and the rest of the mozzarella. Cover the dish with a sheet of aluminum foil and bake for 15 to 20 minutes.

Step 6

Set the oven to the "broil" position. Remove the sheet of aluminum foil from the dish and continue cooking for 2 to 3 minutes until the cheese is golden brown.
