No. If made with parmesan cheese, this recipe is meatless but not vegetarian. Most parmesan cheese contains animal rennet and is not vegetarian. This is also true of other cheeses, such as Pecorino Romano, Grana Padano, and Gorgonzola, and some french cheeses. There are more and more plant-based vegan and vegetarian cheese available every day. So, if eating vegetarian is important to you, look for those.
