A standard packet of chicken bouillon contains about 2 teaspoons of granulated bouillon, which is equivalent to 1 cube or 4.5 grams. This amount will vary depending on the brand and type of bouillon you purchase, so it is important to read the label carefully before adding this ingredient to your dish. When reconstituted with water according to package instructions, each packet yields approximately one cup (8 fluid ounces) of chicken broth or stock.
