Want to save yourself a lot of hassle and effort this Christmas? Then cook my Easy Christmas Vegetable Gratin! All the key Christmas vegetables in one dish. As a bonus this looks much more difficult than it really is…your guests will think you’ve been slaving all morning in the kitchen, when really this takes just 15 minutes prep and then just a little over an hour in the oven. Plus, if you make it in a pretty dish, you can just serve it on the table just as it is…so less washing up to do on Christmas afternoon – hoorah!!
