The 23-year-old who featured for the Black Stars at the 2013 African Cup of Nations Tournament in South Africa sealed a permanent move to the Belgrade side after a successful 4 month loan spell where he scored 16 goals.
His new deal will keep him at Belgrade until 2020. He has previously played on loan at Sassoulo, Genoa and Elche after joining Juventus in 2011.
Boake-Yiadom is hoping to return to the Black Stars soon.
