Combine basil, Parmesan cheese, pepper, garlic, salt, ricotta cheese, and egg in a bowl.
Spoon 1/2 cup pasta sauce in bottom of a 13-inch by 9-inch glass baking dish coated with cooking spray. Layer half of eggplant slices over pasta sauce. Sprinkle eggplant with salt.
Top with 3/4 cup pasta sauce.
Spread half of ricotta mixture over sauce, and top with a third of mozzarella and 1/4 cup fontina.
Repeat layers once, ending with about 1 cup pasta sauce. Cover tightly with aluminum foil coated with cooking spray. Bake at 375 degrees for 35 minutes.
Remove foil and top with remaining third of mozzarella and 1/4 cup fontina. Bake at 375 for 10 minutes or until sauce is bubbly and cheese melts.
