Noble goes off sauce (9)
I believe the answer is:
bolognese
'sauce' is the definition.
(I've seen this before)
'noble goes off' is the wordplay.
'off' is an anagram indicator.
'noble'+'goes'='noblegoes'
'noblegoes' anagrammed gives 'BOLOGNESE'.
(Other definitions for bolognese that I've seen before include "Pasta dish (from an Italian city)" , "Spaghetti dish" , "See 22" , "Meat and tomato sauce" , "Spaghetti sauce" .)
