In this paper we introduce the notion of gradient Einstein solitons as self-similar solutions of the gradient flow associated to the Einstein-Hilbert action. After proving the rectifiability of $f$, we use it to investigate the geometric properties of the solitons. In particular, we show that there is only one complete three-dimensional gradient steady Einstein soliton with positive sectional curvature. This solution is rotationally symmetric and asymptotically cylindrical. Hence, it represents the analogue of the Hamilton's cigar in dimension three. We also consider the class of gradient solitons associated to the flows $\partial_t g = -2(Ric -\rho R\,g)$, for any constant $\rho\neq 0$. In particular, for $\rho=1/2(n-1)$, we classify all complete three-dimensional gradient Schouten solitons in the steady case as well as in the shrinking case.
