No, poultry seasoning and chicken rub are not the same thing. Each blend uses different herbs and spices and they are often used to create very different end results. The main ingredient for poultry seasoning is sage, and often this is used in aromatic recipes such as soups and stuffings. The main ingredient for chicken rub is paprika, but rubs will often include cayenne, cumin, and/or chili powder as well. Typically chicken rubs are used to create a BBQ-style flavor and are great for grilling or air frying.
