The halal status of Parmesan cheese depends on the source of the rennet used in its production. Traditional Parmesan cheese is made with animal rennet, which may not be halal if the animal was not slaughtered according to Islamic law. However, Parmesan cheese can be considered halal if it is made with microbial or plant-based rennet.

For strict followers of halal dietary guidelines, it is recommended to opt for cheese varieties that clearly state the use of microbial or plant-based rennet. Seeking guidance from knowledgeable scholars or halal certification authorities can also help in making an informed decision regarding Parmesan cheese consumption.

And Allah knows best.
