Step 1

Preheat oven to 375 degrees F.

Step 2

Spread sauce in a 9-by-13-inch broiler-safe baking dish. Make crosswise cuts every 1/4 inch along each eggplant, slicing almost to the bottom but not all the way through. Carefully transfer the eggplants to the baking dish. Gently fan them to open the cuts wider. Drizzle 2 tablespoons oil over the eggplants. Fill the cuts alternately with mozzarella and pesto (some cuts may not be filled). Cover with foil.

Step 3

Bake until the eggplants are very tender, 45 to 55 minutes.

Step 4

Combine panko, Parmesan and the remaining 2 teaspoons oil in a small bowl. Remove the foil and sprinkle the eggplants with the breadcrumb mixture.

Step 5

Increase the oven temperature to broil. Broil the eggplants on the center rack until the topping is golden brown, 2 to 4 minutes. Top with basil. Serve with the sauce.
