Croissants D'ilithium was a dish in the 24th century. It was served with cream cheese and tomatoes.

It was offered on the menu at the French Café des Artistes in Paris, France on Earth. In 2364, Captain Jean-Luc Picard visited the holographic recreation of this café including the menu. (TNG: "We'll Always Have Paris")

The name of this dish was an in-joke from the art department.
