In order to obtain this Trophy you must raise Ignis' cooking skill at least once.
Each time you set up camp Ignis will cook a meal for the group. The more Ignis cooks the more experience he gains. Defeating monsters whom Gladiolus finds meat or other ingredients from or from collecting herbs and vegetables from around the world will prompt Ignis to create a new recipe.
Once you make camp or sleep for the night and the Cooking skill goes up to level 2 you will unlock this Trophy.
