Cocotte id a pan with a lid, usually in cast iron. The Le Creuset are most likely the more well known one. They can be small or big.

The French Wikipedia article is clearer than the English one : https://fr.m.wikipedia.org/wiki/Cocotte_(cuisine)

Note that a pressure cooker is called a Cocotte minute. Because it cooks quickly.

Cocotte is also a term that can be used for chickens or chicks, but that has nothing to do with cooking utensils.
