Pastoral deity — dull-looking or a dish? (8)
I believe the answer is:
pandowdy
'a dish?' is the definition.
(type of baked dish)
'pastoral deity dull-looking' is the wordplay.
'pastoral deity' becomes 'Pan' (forest god in Greek myth).
'dull-looking' becomes 'dowdy' (dowdy can mean unattractive or dull).
'pan'+'dowdy'='PANDOWDY'
'or' acts as a link.
(Other definitions for pandowdy that I've seen before include "Apple dessert" , "apple pie" , "pudding" .)
