Preheat oven to 350 degrees F. Cook jumbo shells according to package directions. Using a large slotted spoon, transfer shells to a colander. Rinse with cold water; drain well and set aside.
Meanwhile in a medium bowl whisk together the ricotta cheese, garlic, Italian Seasoning, salt, pepper, 1 cup mozzarella cheese, parmesan cheese and egg.
Spread about 1/2 cup of the pasta sauce in the bottom of a 3-quart rectangular baking dish. Spoon cheese mixture into drained jumbo shells; place stuffed shells in prepared baking dish. Top with remaining pasta sauce.
Bake, covered, for 30 minutes. Uncover and sprinkle with remaining mozzarella cheese. Bake, uncovered, about 15 minutes more or until heated through. Let stand 10 minutes before serving. Top with fresh basil. Enjoy!
