The pasta phase in core-collapse supernova matter (finite temperatures and fixed pro- ton fractions) is studied within relativistic mean field models. Three different calculations are used for comparison, the Thomas-Fermi (TF), the Coexistence Phase (CP) and the Compressible Liquid Drop (CLD) approximations. The effects of including light clusters in nuclear matter and the densities at which the transitions between pasta configurations and to uniform matter occur are also investigated. The free energy and pressure, in the space of particle number densities and temperatures expected to cover the pasta region, are cal- culated. Finally, a comparison with a finite temperature Skyrme-Hartree-Fock calculation is drawn.
