  We consider the Einstein-Gauss-Bonnet gravity with a negative cosmological
constant together with a source given by a scalar field nonminimally coupled in
arbitrary dimension D. For a certain election of the cosmological and
Gauss-Bonnet coupling constants, we derive two classes of AdS black hole
solutions whose horizon is planar. The first family of black holes obtained for
a particular value of the nonminimal coupling parameter only depends on a
constant M, and the scalar field vanishes as M=0. The second class of solutions
corresponds to a two-parametric (with constants M and A) black hole stealth
configuration, that is a nontrivial scalar field with a black hole metric such
that both side (gravity and matter parts) of the Einstein equations vanishes.
In this case, in the vanishing M, the solution reduces to a stealth scalar
field on the pure AdS metric. We note that the existence of these two classes
of solutions is inherent of the particular choice of the coupling constants
and, they can not be promoted to spherical or hyperboloid black hole solutions
in a standard fashion. In the last part, we add to the original action some
exacts (D-1)-forms coupled to the scalar field. The direct benefit of
introducing such extra fields is to obtain black hole solutions with planar
horizon for arbitrary value of the nonminimal coupling parameter.
