In this work, we study the theory of inflation with the non-minimally coupled quadratic, standard model Higgs, and hilltop potentials, through *ξφ*^{2}*R* term in Palatini gravity. We first analyze observational parameters of the Palatini quadratic potential as functions of *ξ* for the high-*N* scenario. In addition to this, taking into account that the inflaton field *φ* has a non-zero vacuum expectation value *v* after inflation, we display observational parameters of well-known symmetry-breaking potentials. The types of potentials considered are the Higgs potential and its generalizations, namely hilltop potentials in the Palatini formalism for the high-*N* scenario and the low-*N* scenario. We calculate inflationary parameters for the Palatini Higgs potential as functions of *v* for different *ξ* values, where inflaton values are both *φ* > *v* and *φ* < *v* during inflation, as well as calculating observational parameters of the Palatini Higgs potential in the induced gravity limit for high-*N* scenario. We illustrate differences between the Higgs potential's effect on *ξ* versus hilltop potentials, which agree with the observations for the inflaton values for *φ* < *v* and *ξ*, in which *v* ≪ 1 for both these high and low *N* scenarios. For each considered potential, we also display *n*_{s} − *r* values fitted to the current data given by the Keck Array/BICEP2 and Planck collaborations.
