Described is a method for preparing a nut paste, comprising the steps of: a) treating the surface of nutshells and/or non-shelled nuts to remove surface contaminants from the shell material; b) preparing a mixture comprising: b1) surface-treated non-shelled nuts, b2) shelled culinary nuts and surface-treated nutshells, and/or b3) shelled culinary nuts and surface-treated non-shelled nuts; and c) grinding the mixture to an average particle size of 500 m or less to provide a nut paste; wherein the mixture contains at least 0.05 wt.-% of surface-treated nutshell material based on the total weight of solids, and wherein the mixture does not contain added water. The method enables optimized extraction and yield of nutritionally beneficial components of both nut kernels and nut shells while enabling fast and inexpensive processing. In addition, a nut paste obtainable by the aforementioned method and the use of surface-treated nut shells and/or surface-treated non-shelled nuts in ground form as filler material in the preparation of food is described.
