This study applies Norm Activation Theory (NAT) to examine meal kit consumers’ cooking intentions, focusing on how perceived responsibility and personal moral norms influence these intentions during meal preparation. A total of 376 adults with prior experience using meal kits participated in an online survey. The collected data were analyzed using exploratory factor analysis, reliability testing, correlation analysis, simple regression, and mediation analysis. The findings reveal five key insights. First, awareness of meal preparation significantly reduced perceived burdens related to cooking outcomes, suggesting that consumers who internalize cooking as a moral practice experience less psychological and temporal stress. Second, awareness of cooking outcomes positively influenced the ascription of responsibility, implying that higher awareness reinforces consumers' moral obligation. Third, the ascription of responsibility played a central role in activating personal norms. Fourth, personal norms were strong predictors of cooking intentions, with ascribed responsibility being the most influential antecedent. Fifth, the mediation analysis confirmed that personal norms partially mediated the relationship between responsibility and cooking intention. This study extends the theoretical application of NAT to the domain of food and consumer behavior, interpreting cooking as a morally motivated act. Practically, the findings suggest that meal kit companies should design marketing and branding strategies that reflect consumers’ sense of responsibility and ethical engagement in food preparation.
