Is Mozzarella Vegetarian & Halal?

Cheese, a staple in many diets, has been a topic of discussion and scrutiny among vegetarians. One popular cheese that raises questions is mozzarella.

Traditionally made from cow’s milk, the vegetarian and halal status of mozzarella cheese is not as straightforward as one might think.

The key concern lies in the type of rennet used in the cheese-making process.

This article will delve into the ingredients of mozzarella cheese, the role of rennet, and ultimately answer the question: Is mozzarella cheese vegetarian and halal?

How is Mozzarella Made?

Understanding the mozzarella making process is crucial to determine if it is vegetarian.

The primary ingredients of mozzarella are milk, rennet, and a bacterial culture.

The process typically involves the following steps:

  1. Milk selection: The first step involves choosing the milk source, traditionally water buffalo or cow’s milk. High-quality milk is crucial to create the perfect texture and flavor of mozzarella.
  2. Pasteurization: Milk is pasteurized to eliminate harmful bacteria and ensure food safety.
  3. Culturing: A bacterial culture is added to the milk, which helps convert lactose into lactic acid. This acidification process is essential for curdling the milk.
  4. Coagulation: Rennet is added to the milk to coagulate it. The enzymes in rennet cause the milk proteins to form solid curds, separating them from the liquid whey.
  5. Cutting and stirring: The curds are cut into small pieces and stirred to encourage whey separation and curd firming.
  6. Draining and molding: The curds are drained of excess whey and molded into desired shapes, typically balls or blocks.
  7. Salting: The mozzarella is salted to enhance flavor and act as a preservative.
  8. Aging: The cheese is allowed to age for a short period, usually a few hours to several days, depending on the desired texture and taste.

Is Mozzarella Cheese Vegetarian?

The critical factor in determining whether mozzarella is vegetarian lies in the rennet source.

Traditional mozzarella uses animal rennet, which is obtained from the stomach lining of calves, making it non-vegetarian. 

Fortunately, there are alternatives for vegetarians seeking to enjoy mozzarella without compromising their dietary choices.

Vegetarian mozzarella uses microbial or vegetable rennet to coagulate milk.

Microbial rennet is derived from fungi or bacteria, while vegetable rennet is extracted from plants like thistle or fig leaves.

Both options offer similar coagulation properties to animal rennet and result in vegetarian-friendly cheese.

To ensure you are purchasing vegetarian mozzarella, look for labels indicating “vegetarian,” “microbial rennet,” or “vegetable rennet” on the packaging.

Many brands now produce vegetarian mozzarella to cater to the growing demand for plant-based alternatives.

Is Mozzarella Cheese Halal?

The halal status of mozzarella cheese depends on the ingredients used and the certification of the manufacturing facility.

  1. Ingredients: Traditional mozzarella cheese is made from milk, rennet, and salt. The halal status depends on the type of rennet used. Rennet can be derived from animal, microbial, or vegetable sources. Animal-derived rennet from non-halal slaughtered animals would make the cheese non-halal. However, if the rennet is microbial or vegetable-derived, or from halal-slaughtered animals, it could be considered halal.
  2. Certification: Even if the ingredients are halal, the manufacturing facility must also be certified halal, meaning it adheres to Islamic dietary laws and avoids cross-contamination with non-halal substances.

It is always recommended to check for a halal certification on the packaging or contact the manufacturer for more information.


The traditional mozzarella is not vegetarian due to the presence of animal rennet.

However, there are vegetarian alternatives available. By using microbial or vegetable rennet, cheese manufacturers can create vegetarian-friendly mozzarella that caters to an ever-increasing audience seeking plant-based options.
