Both Creole and Cajun cooking terms are used interchangeably. However, Cajun seasoning is a basic blend mix: use garlic powder, onion, black pepper, and Cayenne pepper. While creole seasoning goes a bit further than these basic spices with more herbs ranging from oregano to basil and paprika.
3 Tablespoons onion powder
3 Tablespoons garlic powder
1 ½ Tablespoons black pepper
1 ½ Tablespoons white pepper

½ - 1 Tablespoons cayenne pepper (adjust to suit taste buds)
1 1/2 Tablespoons oregano
1 Tablespoon dried parsley
1 1/2 Tablespoons dried thyme
1 1/2 Tablespoons dried basil
Combine all the ingredients thoroughly and store airtight.
