We present new supergravity backgrounds generated by N-c D5-branes, wrapping the S-2 of the resolved conifold, in the presence of N-f = 2N(c) smeared flavor D5-branes. The smearing allows us to take into account their backreaction on the geometry. We discuss the consistency, stability, and supersymmetry of these types of setups. We find near horizon geometries that we expect to be supergravity duals of SQCD-like theories with N-f = 2N(c). From these backgrounds, we numerically extract rectangular Wilson loops and beta functions of the dual field theory for the regime where our approximations are valid.
