The Old Bailey heard that when investigators searched Brizzi's home in Southwark, south London, PC Semple's DNA was found on the blade of a blender, a cooking pot, chopsticks, on a chopping board and in the oven.
Officers also discovered bite marks on a piece of bone recovered from the kitchen, the jury was told.
Crispin Aylett QC, prosecuting, said: "The defendant cannot have confined himself to dismembering Gordon Semple and disposing of his body either by acid in the bath or else in the dustbins.
"Instead, the prosecution suggest it would be open to the jury to find that the defendant cooked part of his body and ate it."

The 50-year-old later allegedly claimed he disposed of body parts he had been unable to break up by taking them on his bicycle to a quiet spot by the River Thames.
Brizzi said there was still a foot, hand and leg at his flat "which I tried to roast as well", the court was told.
While in the custody suite after his arrest, the Italian allegedly said: "I thought I was getting away with it.
"I had nearly finished but I took a shot (of crystal meth). I was going to finish the job today.
"As you can see, this man was a very big man and all I have left is two buckets."
