The objective of this study is to examine and explain the determinant factors related to halal food consumption within the Indonesian Muslim minority group living in Belgium. The research used the quantitative methodology, the theory of planned behavior (TPB) and Islamic religiosity (IR) as a conceptual framework. Questionnaires were collected between December 2017 and January 2018, in Antwerp, Leuven, Gent, and Brussels, during the Islamic community gathering (pengajian), the Friday prayer (jumatan), and the periodic community gathering (arisan). Descriptive statistics were used to explain the Indonesians’ socio-demographic characteristics. Correlations and multiple regression analyses were employed as a basis for the application of TPB, IR and consuming intention. This research is the first to apply the TPB framework to Indonesian Muslims as a religious minority group living in Belgium regarding the issue of halal food consumption.
