The research, by retail giant Tesco, also looked at which areas were more veg-friendly than others.
There's a clear North/South divide going on, with Brighton being crowned the 'vegan capital of the UK' - 12 percent of residents plan to serve up a vegan festive feast. In Scotland, however, just five percent are making plant-based preparations.
Supermarket vegan options
If you want proof of just how many people are opting for plant-based alternatives, you no longer have to seek out a branch of Whole Foods to pick up a Tofurky - there are many options are regular supermarkets.
Tesco is selling cauliflower wellingtons (£6) and festive nut roasts with mulled wine and cranberry (£3.50), while Waitrose has vegan chocolate tortes (£15) as well as a vegan Christmas cake (£7.50).
Alessandra Bellini, Tesco's Chief Customer Officer, said: "Our research found that, by and large, we’re still a nation of traditionalists – but with a third of people mixing things up at Christmas each year, that is changing."
