The Jennifer Saunders and Joanna Lumley sitcom, which has been revived for two 20th anniversary specials, is expected to feature in the channel's Christmas Day schedule alongside Doctor Who, EastEnders and Strictly Come Dancing.
David Jason's first new BBC comedy in 20 years, The Royal Bodyguard, will also air over the winter period.
Despite The Royle Family taking a break this Christmas, actress Sue Johnston will still be seen on BBC One in one-off comedy Lapland.
Elsewhere, Ray Winstone, Gillian Anderson and David Suchet star in an adaptation of Great Expectations, while Stephen Fry, Victoria Wood and Christopher Eccleston lend their talents to The Borrowers.
