Step 1

Pour enough oil in a heavy large saucepan to reach the depth of 3 inches. Heat the oil over medium heat to 350 degrees F.

Step 2

Stir the eggs, risotto, Parmesan, and 1/2 cup of the bread crumbs in a large bowl to combine. Place the remaining breadcrumbs in a medium bowl. Using about 2 tablespoons of the risotto mixture for each, form the risotto mixture into 1 3/4-inch-diameter balls. Insert 1 cube of mozzarella into the center of each ball. Roll the balls in the bread crumbs to coat.

Step 3

Working in batches, add the rice balls to the hot ail and cook until brown and heated through, turning them as necessary, about 4 minutes. Using a slotted spoon, transfer the rice balls to paper towels to drain. Season with salt. Let rest 2 minutes. Serve hot.
