Cajun seasoning
Also known as cajun spice, cajun rub, blackening seasoning
Quick answer
A Louisiana seasoning built on paprika, cayenne, garlic, onion and dried herbs. Distinct from Creole seasoning, which is generally more herb-forward — a difference frequently collapsed outside Louisiana.
In essentially every version: Paprika, Cayenne pepper, Garlic powder, Onion powder, Black pepper, Oregano, Thyme.
2distinct versions are recorded below. None of them is presented as the correct one, because there isn’t one.
What goes in it
The defining core first, then the versions. Roles are recorded so it is clear what each ingredient is doing.
| Ingredient | Role | How essential |
|---|---|---|
| Paprika (ground) | colour | defining |
| Cayenne pepper (ground) | heat | defining |
| Garlic (powder) | savoury depth | defining |
| Onion (powder) | savoury depth | defining |
| Black pepper (ground) | heat | usual |
| Oregano | supporting aromatic | usual |
| Thyme | supporting aromatic | usual |
The main axis of variation is heat and salt. Commercial blends are usually heavily salted, so a recipe written for a home blend will over-salt a dish if a packet is used at the same rate. The Cajun and Creole distinction is real: Creole seasoning generally carries more dried herbs and sometimes paprika-forward sweetness, while Cajun is more pepper-driven. Outside Louisiana the two names are used almost interchangeably, which is worth noting rather than reproducing.
The versions
Each attributed, with how firm its proportions are stated plainly.
Unsalted home blend
contemporary commonCommon domestic practice · proportions representative · medium confidence
An unsalted base so that salt can be judged separately — the more controllable option for cooking.
| Ingredient | Parts | Share |
|---|---|---|
| Paprika | 4 | 33% |
| Garlic powder | 2 | 16% |
| Onion powder | 2 | 16% |
| Black pepper | 1 | 8% |
| Cayenne pepper | 0.5–2 | 10% |
| Oregano | 1 | 8% |
| Thyme | 1 | 8% |
The cayenne range is deliberately wide: this is the component people most reasonably differ on.

Salt-forward, as most retail blends are. Recorded so that the difference from a home blend is visible rather than surprising.
| Ingredient | Parts | Share |
|---|---|---|
| Salt | 3–6 | 40% |
| Paprika | 3 | 27% |
| Garlic powder | 1 | 9% |
| Onion powder | 1 | 9% |

Using it
Rubbed on generously and cooked over high heat, often in a very hot dry or lightly buttered pan for blackening. Check whether your blend contains salt before salting the dish separately.
Savoury and pepper-driven, with sweet red-pepper body from the paprika, a herbal backbone and a clean building heat. Designed to form a crust under high heat, which is the basis of blackening.
Medium to hot, depending almost entirely on the cayenne proportion.
- Blackened fish
- Chicken
- Prawns
- Rice dishes such as jambalaya
- Roast potatoes
- Corn
Scaling: Scales linearly and keeps well. Making it unsalted and salting separately gives far more control across different dishes.
What to use it on
Chicken
StrongThe blend is designed for high-heat cooking and chicken takes it directly. The paprika forms a crust and the cayenne provides heat that chicken's mildness does not fight.
If you have none
Paprika with Cayenne pepper and Black pepper
Good matchUse: ~1× by volume — About four parts paprika to one part cayenne and one part black pepper, at the same total volume. Add garlic powder and dried oregano or thyme if you have them.
Cajun seasoning is not a mysterious blend — paprika for colour and body, cayenne for heat, black pepper, garlic and herbs. This gets most of the way there. The herbs are what separate a passable version from a good one, and the salt level is yours to set, which is usually an improvement over the packet.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| close | close | very close | similar |
Works for
- Blackened fish and chicken, where the paprika crust is the point
- Prawn and shellfish dishes
- Rice dishes, gumbo and jambalaya
Does not work for
- Anywhere the packet was providing the salt, since this brings none
- Recipes wanting the full herb profile without adding oregano and thyme
Cuisine: Stays in Louisiana. The distinction between Cajun and Creole seasoning turns largely on the herbs, so leaving them out drifts towards a plain paprika rub.
Taco seasoning with Cayenne pepper and Oregano
SituationalUse: ~1× by volume — Equal volume of taco seasoning with a pinch of cayenne and a pinch of dried oregano stirred in.
A cupboard answer rather than a good one. Both are paprika-led American blends, but taco seasoning carries a great deal of cumin, which Cajun seasoning does not, and the result reads as Tex-Mex rather than Louisiana. Adding cayenne restores the heat and oregano some of the herb character; the cumin cannot be removed.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | partial | close | less |
Works for
- Blackening or a quick rub where only the paprika crust matters
- Emergencies, having accepted the dish will taste of cumin
Does not work for
- Gumbo, jambalaya and dishes where the Louisiana identity is the point
- Anything already containing cumin, which will become dominant
Cuisine: Moves the dish from Louisiana to the Texas-Mexico border. Recognisable to anyone who knows either.
The better answer is the from-scratch reconstruction recorded separately on this page. This one is for when the cupboard has a packet and nothing else.
Storage
Good for: 6–18 months (typically 12 months)
Cool, dark, dry, airtight.
A faded blend is a quality matter; hard caking from moisture is a reason to discard.
Allergens and safety
Culture and origin
Louisiana, from the rural Acadian (Cajun) cooking tradition. The packaged seasoning is a twentieth-century commercial development built on that tradition rather than a historical artefact of it.
Louisiana
Cajun and Creole cooking are distinct traditions with different histories — rural Acadian and urban New Orleans respectively — and their seasonings differ accordingly. Treating the words as synonyms erases a real distinction that matters locally.
