You probably already have most of the spices you need to make this right in your spice cabinet!
This blend is great when used in this recipe for Instant Pot Red Beans and Rice and so much more!
Some of the flavors/foods you find most in Cajun Cuisine are paprika, garlic, thyme, cayenne, bay leaf, seafood, rice, and sausage.
The sweetness and molasses flavors of the brown sugar are great when used with pork or seafood, like in this Cajun Salmon.I would only add the brown sugar on a per recipe basis, not in the entire jar.
Just like any store-bought seasoning, keep this Cajun Blend in an airtight container in your spice cabinet.
