   When the polenta begins to bubble, reduce the heat to low and continue to cook, whisking steadily, until the mixture is thick and pulls away from the pot, about 30 minutes.

   Then remove it from the heat.
6. 6
   Oil two 8-inch square baking pans and pour the polenta into them, dividing equally.

    Spoon half of the sauce evenly over the polenta squares and top with half of the mozzarella and half of the Parmesan.
