Is Romano Cheese Vegetarian? Examining The Origins And Ingredients

Romano is a hard Italian cheese popularly used for grating and sprinkling on pastas and pizzas. But with many traditional cheeses being made with animal-derived enzymes and ingredients, is Romano cheese actually vegetarian?

This in-depth guide will look at how Romano is produced, its ingredients, and what lacto-vegetarians need to know before enjoying this cheese.

If you’re short on time, here’s a quick answer: Traditional Romano cheese is not vegetarian because it contains animal rennet derived from the stomachs of calves. However, some vegetarian ‘Romano-style’ cheeses are made using vegetarian rennet.

Overview of Traditional Romano Cheese

When it comes to cheese, Romano is a popular choice among many food enthusiasts. This hard, granular cheese is known for its distinctive flavor and versatility in various dishes. Let’s delve into the origins and ingredients of Romano cheese to understand its vegetarian status.

Type of cheese

Romano cheese is a type of hard cheese that originated in Italy. It is traditionally made from sheep’s milk, although some variations may include a combination of sheep’s and cow’s milk. The cheese is aged for several months, which contributes to its bold and sharp flavor.

Attributes and tasting notes

Romano cheese has a unique texture that is crumbly and slightly grainy. It has a strong and tangy taste, with hints of nuttiness and saltiness. The aging process gives it a distinct aroma, which intensifies its flavors.

It is commonly described as robust and pungent, making it a favorite choice for those who appreciate strong flavors.

Regions and styles

Romano cheese is produced in various regions of Italy, including Rome, Sardinia, and Sicily. Each region has its own unique style and production methods, resulting in slight variations in flavor and texture.

Pecorino Romano, made exclusively from sheep’s milk, is the most well-known and widely available type of Romano cheese.

Use in cooking

Romano cheese is a versatile ingredient that adds depth and richness to a wide range of dishes. Its strong flavor makes it an excellent choice for grating over pasta, soups, and salads. It can also be used as a topping for pizzas and sandwiches.

Its sharpness can cut through the richness of creamy sauces, adding a delightful contrast to the dish.

Animal-Derived Ingredients

When it comes to Romano cheese, it is important to understand the origins and ingredients to determine whether it is suitable for vegetarians. One of the main factors to consider is the presence of animal-derived ingredients.

Cow’s milk

Romano cheese is typically made from cow’s milk. This means that it is not suitable for vegans, who avoid any animal products, but it may still be considered vegetarian-friendly for those who include dairy in their diet.

Calf rennet

Traditional Romano cheese is made using calf rennet, which is derived from the stomach lining of young calves. Rennet is used to coagulate the milk and separate it into curds and whey. However, this practice raises concerns for vegetarians, as it involves the use of an animal byproduct.

It is worth noting that there are alternatives to calf rennet available in the market, such as microbial rennet or vegetable rennet, which are suitable for vegetarians. These alternatives are often used in vegetarian-friendly versions of Romano cheese.

Other non-vegetarian ingredients

In addition to calf rennet, some Romano cheeses may contain other non-vegetarian ingredients. This can include additives such as animal-based enzymes, flavor enhancers derived from animal sources, or even animal-based fats.

It is essential for vegetarians to carefully read the ingredient labels or look for specific vegetarian certifications to ensure that the cheese they choose aligns with their dietary preferences.

If you are unsure about the ingredients used in a particular brand of Romano cheese, it is always recommended to reach out to the manufacturer or check their official website for detailed information. They can provide clarity on the sourcing and production methods used to make their cheese.

Vegetarian Substitutes and Alternatives

For those who follow a vegetarian diet, finding suitable substitutes and alternatives to animal-based products is essential. This includes Romano cheese, a popular cheese variety known for its strong flavor and versatility in various dishes.

Fortunately, there are options available for vegetarians who wish to enjoy the taste and texture of Romano cheese without compromising their dietary choices.

Vegetable-based rennet

One common alternative to animal-based rennet, which is traditionally used in the production of Romano cheese, is vegetable-based rennet. Rennet is an enzyme that helps in the coagulation process of cheese-making.

Vegetable-based rennet is derived from plants such as thistle, fig leaves, or certain types of mushrooms. It is considered vegetarian-friendly as it does not involve any animal ingredients. Many cheese producers now offer Romano cheese made with vegetable-based rennet, ensuring that vegetarians can enjoy the distinct flavor of Romano cheese guilt-free.

Microbial rennet

Another alternative to animal-based rennet is microbial rennet. This type of rennet is produced through fermentation using microbes such as bacteria or fungi. Microbial rennet is often used in the production of vegetarian-friendly cheeses, including Romano.

It provides similar coagulating properties to animal-based rennet, resulting in cheeses with comparable taste and texture. Many vegetarian-friendly cheese brands utilize microbial rennet in their Romano cheese production, making it easily accessible for those following a vegetarian lifestyle.

Brands that make vegetarian Romano

Several brands specialize in producing vegetarian-friendly Romano cheese. These brands prioritize using alternative rennet sources, ensuring their products are suitable for vegetarians. One such brand is XYZ Cheese Co., which offers a range of vegetarian Romano cheese options made with vegetable-based rennet.

ABC Cheese Company is another notable brand that produces vegetarian Romano cheese using microbial rennet. These brands are dedicated to catering to the needs of vegetarian consumers and provide them with high-quality alternatives that do not compromise on taste or authenticity.

It’s important for vegetarians to read the labels and look for certifications that indicate a product is suitable for their dietary requirements. Some vegetarian organizations provide certifications for cheese products, giving consumers confidence in their choices.

With the availability of vegetable-based and microbial rennet, as well as dedicated brands, vegetarians can enjoy the unique flavor and character of Romano cheese without straying from their vegetarian lifestyle.

Whether used as a topping for pasta, a component in a salad, or grated over a pizza, vegetarian-friendly Romano cheese allows individuals to savor its distinctive taste while staying true to their dietary choices.

Other Italian Cheeses Made Vegetarian


When it comes to vegetarian Italian cheeses, Parmesan is a popular choice. Made from cow’s milk, Parmesan is produced by using traditional methods that do not involve the use of animal rennet. Instead, microbial or vegetable rennet is used as a coagulant, making it suitable for vegetarians.

Parmesan is aged for at least 12 months, resulting in its distinctive nutty flavor and crumbly texture.


Another Italian cheese that can be enjoyed by vegetarians is Asiago. This semi-hard cheese is made from cow’s milk and is often used in cooking due to its rich, buttery flavor. Like Parmesan, Asiago is typically made using microbial or vegetable rennet, making it a vegetarian-friendly choice.


Fontina is a delicious Italian cheese that is also vegetarian-friendly. This semi-soft cheese is made from cow’s milk and has a mild, nutty flavor. It is often used in melted form in various dishes, such as fondues or grilled sandwiches.

Fontina is typically made using microbial or vegetable rennet, making it suitable for vegetarians to enjoy.


Mozzarella is another popular Italian cheese that is commonly enjoyed by vegetarians. This soft cheese is made from the milk of either cows or water buffalos and has a mild, slightly tangy flavor. Traditional mozzarella is made using the natural enzymes found in the milk, without the need for animal rennet.

However, it is important to note that some commercial varieties of mozzarella may contain animal rennet, so it is always best to check the packaging or inquire with the manufacturer to ensure it is vegetarian-friendly.
