In the US, recipes that are not just a list of ingredients, which would be most recipes, are covered by copyright.[0]
"Copyright protection may, however, extend to substantial literary expression—a description, explanation, or illustration, for example—that accompanies a recipe or formula or to a combination of recipes, as in a cookbook."
Note that 'substantial' here doesn't mean it needs to be novella length. A simple description of the steps involved would be enough.
