The invention relates to a method for manufacturing a soluble coffee tablet comprising the following successive steps: a. Taking a quantity of a coffee composition comprising coffee, wherein the coffee consists of soluble coffee particles b. Compaction of the coffee composition to form a compacted coffee product of three-dimensional form c. Moistening of said compacted coffee product to moisten the exterior surface of the compacted product d. Drying of the moistened compacted product to form the soluble coffee tablet. Such a method makes it possible to form a soluble coffee tablet having an internal part and an external part entirely surrounding the internal part, with the external part having a greater density than the density of the internal part. The internal part is a porous core promoting the dissolution of the tablet and the external part forms a thick hardened crust with a density greater than the density of the core, thus increasing the mechanical resistance of the tablet.
