We prove the following Bernstein-type theorem: if $u$ is an entire solution to the minimal surface equation, such that $N-1$ partial derivatives $ \frac{\partial u }{\partial {x_j}}$ are bounded on one side (not necessarily the same), then $u$ is an affine function. Its proof relies only on the Harnack inequality on minimal surfaces proved in \cite{BG} thus, besides its novelty, our theorem also provides a new and self-contained proof of celebrated results of Moser and of Bombieri $\&$ Giusti.
