The best vegan shredded cheese for mac and cheese varies based on personal preference. Here's a list of all the vegan cheeses that I've tested for this recipe: Emborg, Farm Boy, Ilchester Applewood, Nafsika’s Garden, Nurishh, Parmela Creamery, Violife, Vitalite. My personal favourite brand is Daiya; although it has a controversial smell and isn't necessarily the tastiest choice in other applications, it melts very nicely into the mac and cheese sauce, and it has a great strong cheesy flavour. Not to mention, it's one of the most affordable vegan cheese brands. These brands offer a range of flavors and meltability, making them suitable for creating creamy and flavorful vegan mac and cheese. The choice often depends on factors like taste, texture, and dietary preferences, and experimenting with different brands can help you find the one that suits your mac and cheese recipe best.
