Short answer Traditional basil pesto is not vegetarian because animal rennet is used in the production of the cheeses it contains. However, it is perfectly possible to create vegetarian pesto using cheese substitutes such as tofu or nutritional yeast.
Long answer We're often asked whether pesto is vegetarian, and people are surprised when we say it's not. The reason is because classic basil pesto contains pecorino and Parmigiano-Reggiano, which are both made from milk curdled in animal rennet. That means that most of the pesto sauces you see on supermarket shelves are not vegetarian.
Animal rennet is used in Italian hard cheese production because this complex set of enzymes can quickly separate milk into curds and whey. The rennet itself comes from the lining of a calf's stomachs before being washed, brined, salted, and used.
You may wonder why no onehas been clever enough to make a non-animal rennet. Well, they have, but Italian producers of Parmigiano-Reggiano not only continue to use animal rennet out of respect for tradition but also because EU law dictates that the cheese cannot be sold under that name if it doesn't contain it.
All is not lost, though. If you are making pesto yourself, you can easily switch the traditional cheese for a vegetarian alternative. Nutritional yeast is the magic ingredient preferred by producers of vegetarian pestos because it's cheaper than cheese but still has the same cheesy flavour. Better still, it doesn't just make the sauce vegetarian; but it makes pesto vegan too.

animal rennet
Rennet has traditionally been used to separate milk into solid curds and liquid whey, used in the production of cheeses. Rennet from calves has become less common for this use, to the point that less than 5% of cheese in the United States is made using animal rennet today.
Sadly, classic basil pesto is not vegan because it contains Parmesan and Pecorino, which are both cheeses made from dairy. However, there are plenty of vegan pesto sauces available, many of which use nutritional yeast to replicate the taste of cheese.
Pesto. If it doesn't specify it's veggie, it's likely to contain our old meaty friend, Parmesan. Most traditional pesto recipes and shop-bought jars won't be suitable for vegetarians. It's worth double-checking pizzas and pastas which contain a drizzle of pesto, just to be sure.
Unfortunately, most supermarket pesto brands aren't vegetarian. Parmesan, a key ingredient in pesto, contains rennet which is an enzyme found in the stomach of a goat or calf. It's not just Parmesan. Pecorino Romano, Manchego, Gruyère and Gorgonzola all contain rennet.
So Why Isn't Parmesan Cheese Vegetarian? This answer is encapsulated in one word: rennet. Specifically animal rennet, collected from slaughtered cows, goats or other young, milk-fed ruminant animals.
Similar to the vegan labels, there are also labels for vegetarian products. The most common one is the vegetarian category of the yellow V-label. Even if chances are the vegetarian label has been added for good reason, it's still worth checking the ingredients.
Like many other types of cheese, authentic mozzarella uses animal rennet, a substance obtained from the stomach lining of young animals that have not yet been weaned. Many vegetarians and lactose intolerants cannot consume mozzarella and a variety of other classic European cheeses due to this restriction.
Barilla Vegan Basil Pesto has an intense basil flavour and creamy texture, just like our Pesto Genovese. Made without any cheese or dairy substitutes, Vegan Basil Pesto is the perfect choice for both lactose intolerant and vegan guests.
Younger, soft cheeses like mozzarella, cottage cheese, cream cheese, ricotta, goat, and provolone often are not made with rennet. However, this isn't an exhaustive list, so be sure to read your labels carefully!.
The classic one is basil, but you can also have the cherry tomato kind, the bell pepper one or tapenade with black olives. Those would do great on toasts or in pastas. Substitute for what? Pesto is just one sauce for pasta, so any other of the thousands of sauces for pasta can substitute it.
Is pesto vegan friendly? The classic pesto recipe is, unfortunately, not vegan because it's made with fresh basil, garlic, pine nuts, oil, and parmesan cheese. Thankfully, it doesn't take much to make a delicious vegan pesto. Just remove the dairy and mix and match a few other ingredients.
Basil stems can be used in the pesto, but make sure to remove any extra thick stems so that they don't get stuck in your blender or food processor. Pine nuts can be used instead of the walnuts for a more traditional pesto.
