Richly seasoned stew shown in red-top abroad (6)
I believe the answer is:
ragout
'richly seasoned stew' is the definition.
(I've seen this before)
'red-top abroad' is the wordplay.
'red-top' becomes 'rag' (both can mean a tabloid newspaper).
'abroad' becomes 'out' (abroad can mean away or out).
'rag'+'out'='RAGOUT'
'shown in' acts as a link.
(Other definitions for ragout that I've seen before include "food ..." , "Seasoned stew of meat and vegetables" , "Spicy meat stew" , "Rich stew" , "Spicy dish" .)
