A style of cooking by a French chef called Michel Guerard
Cooking isn't a loanword from French, but "cuisine" is.
I think you are referring to what is called a croque en bouche.
home cooking is translated "cuisine familiale" in French
The French word for cooking is cuisinière
They are called french fries because of the way they are cut and the way they are cooked. In cooking, a long thin cut is called a french cut, and then of course they are fried, so you get french fries. I wouldn't be surprised to find out they were once called french cut fried potatoes and it just got shortened along the way.
Creoles are what the french were called after the Louisiana Purchase. Some chose to stay, and their style of cooking was widely adapted by the Americans, since it tasted so delicious.
