KFC is giving away free pots of gravy with every order until 3 January if you use its mobile app.
The restaurant said it's all part of the Christmas spirit - with the holiday season being one of the busiest of the year in branches.
"Nothing makes the festive season quite like a bit of gravy, and Christmas is in full swing over here at KFC HQ," the chicken chain said in a statement.
"So, what better way to spread the festive cheer than by giving away free pots of the good stuff."
It added: "Whether you’re looking to dunk, drizzle or drench, we guarantee this’ll put a festive pep in your step and get your tail feathers shaking.
"All you gotta do to get involved is select 'add on a free Regular Gravy' to your order on the KFC mobile app, available for takeaway and drive thru.
"That’s all folks, the Colonel’s got you covered [in gravy]."
KFC is having a gravy filled Christmas this year overall.
It's new festive headliner is a chicken gravy burger.
The new addition to the menu features an Original Recipe chicken fillet, topped a layer of gravy mayonnaise, a slice of melted cheese and a hash brown "gravy boat" for pouring gravy onto.
The hash brown gravy boat has been specially designed to hold gravy - and plenty of it.
And it seems they have good reason to link the holiday season with their gravy - with a remarkable number of British families using KFC gravy with their Christmas Day turkey.
A million pots are sold in the run up to Christmas, a 20% increase from the rest of the year, KFC said.
“Christmas is our busiest time of year, and gravy is part of that,” Senior brand and innovation manager for KFC UK Marcus Buck told Vice.
He added: "People seem to think they’re in on a secret, that it’s their family tradition. There’s pride to it. But in reality, lots of people do it."
