The first, called Family Super Food, will be on the subject of "healthy eating for the family", and the second, Jamie’s Christmas, will be "a long awaited Christmas book".
The news breaks a pattern where Oliver traditionally only publishes one title per year in the autumn season. The release date for each new book publishing in 2016 has yet to be disclosed.
Louise Moore, managing director of Michael Joseph, said: “It is every publisher’s dream to have an author like Jamie and to have two books in one year is truly a gift for us and his fans. I can’t wait to eat from the Family Super Food book, and Christmas is such a stressful time for the cook in the family, so who better to hold your hand through the most important meal of the year.”
