Casserole rises with cooking (5,4)
I believe the answer is:
irish stew
'casserole' is the definition.
(I've seen this before)
'rises with cooking' is the wordplay.
'cooking' indicates an anagram (cook can mean to falsify or distort).
'rises'+'with'='riseswith'
'riseswith' anagrammed gives 'IRISH STEW'.
(Other definitions for irish stew that I've seen before include "Mutton/onion/potato dish" , "Mutton and vegetable dish" , "Traditional meat dish" , "Fare" , "Pale broth, usually of lamb and mixed vegetables" .)
