Through the application of mathematical methods developed in a recent paper, we obtain a closed expression for the chiral correction to the free energy of a bag, due to the presence of the external pionic field in a hedgehog configuration. Low- and high-temperature developments are given and, in particular, the zero-temperature limit is shown to be consistent with previous evaluations of the Casimir energy. The subject of renormalization is also discussed.
