There are so many good vegetarian cookbooks to choose from these days, it's easy to shift to a plant-based diet without sacrificing interest and excitement about your food. If you're going vegan, there are some very good specialized vegan cookbooks, though vegetarian cookbooks published now often provide substitutes for those avoiding eggs and dairy. Also worth noting are books that while not 100% vegetarian—they may have some meat recipes or ingredients in there—have many 'veg-forward' recipes that are unmissable. (eg. some recent Yotam Ottolenghi books). Diane Seed's Top One Hundred Pasta Sauces is also very vegetable friendly.

As the food writer Alicia Kennedy explains, the best vegan cooking is just excellent cooking, on its own terms. She recommends five vegan cookbooks to help you get to grips with vegan cooking techniques and to understand the range of vegan culinary possibilities.
