Criticise Figaro as tiresome part (5)

I believe the answer is:

roast

'criticise' is the definition.
(I've seen this before)

'figaro as tiresome part' is the wordplay.
'part' says the answer is hidden in the clue.
'ROAST' can be found hidden inside 'figaro as tiresome'.

(Other definitions for roast that I've seen before include "Traditional Sunday lunch" , "open-air party in US" , "Oven-cook, tease" , "Heavily criticise" , "Traditional Sunday joint?" .)

I've seen this clue in The Sun.
