Stefano Brizzi, 50, has been jailed for life for strangling a police officer during a bondage sex session and then attempting to cook and eat parts of his body.
Brizzi admitted he was inspired by his favourite TV series Breaking Bad as he tried to get away with killing 59-year-old Pc Gordon Semple by also dissolving his flesh in an acid bath.
Last month, the former Morgan Stanley IT developer was found guilty of murder by a majority of 10 to two after a jury at the Old Bailey had deliberated for more than 30 hours.
Semple was a "caring and gentle person" and "much loved" by his family, who were left devastated with the news of his murder, the court heard.
The trial had heard that Brizzi met his victim on gay dating app Grindr and arranged a "hot, dirty, sleazy session" at his flat near London's Tate Modern gallery on April 1.
According to Brizzi, Semple died when a dog leash he had been wearing slipped as they played a "strangulation game". But a pathologist concluded that while strangulation was a possible cause of death, it would have taken minutes rather than moments, as the defendant had claimed.
In the days after the killing, Brizzi was caught on CCTV buying buckets, a perforated metal sheet and cleaning products from a DIY store. He then set about dismembering the body, stripping the flesh, burning some in the oven and mixing some with acid in the bath.
Semple's long-term partner, Gary Meeks, reported him missing when he failed to return to their home in Dartford, Kent.
Neighbours complained about the stench coming from Brizzi's flat and eventually called police, who came across the grisly sight of "globules" of flesh floating in the bath, bags containing bones and a part of Semple's head, and pools of human fat in the oven.
Following his arrest, Brizzi admitted killing and trying to dissolve the body of the policeman because "Satan told me to".
Brizzi denied trying to cannibalise parts of Semple by cooking and then biting into a rib found in his kitchen bin. But at his sentencing, the prosecution said an expert odontologist had since confirmed that even though Brizzi claimed not to remember it, he had in fact tried to eat human flesh.
Judge Nicholas Hilliard QC handed crystal meth addict Brizzi life in prison with a minimum of 24 years. Brizzi was also sentenced to seven years for obstructing a coroner, which will run concurrently.
The judge said there were "terrible features" of the case and that Brizzi's drug addiction had ruined his life. He told Brizzi: "Regret you express now for Mr Semple's death has to be seen against what you did over a number of days to his body."
The defendant sat in the dock with his head bowed throughout the hearing.
