This Blackened Cajun Seasoning is packed with the bold, smoky spices used in traditional blackening-a cooking process made famous by Chef Paul Prudhomme in New Orleans. It involves coating meat or fish in melted butter and a Cajun and Creole seasoning mix, then searing it in a hot cast iron skillet until a spicy, flavorful blackened crust forms. You can read more about the method here.

I use this blend to add big, bold flavor to Oven Blackened Salmon, Air-Fryer Seasoned Fries, and Parmesan Panko-Crusted Cod. It's also great on roasted chicken, tossed with veggies, stirred into pasta sauces, or sprinkled over rice and stews-no cast iron pan required.

🍋Ingredients

See recipe card at the bottom of the post for the full list of ingredients and exact amounts.

  • Smoked paprika. Adds deep, smoky flavor. You can use regular sweet paprika as a substitute, but you'll lose the smoky flavor.
  • Garlic powder & onion powder.  A savory base that ties the whole blend together.
  • Dried oregano & thyme. Herbs add earthy flavor to this blackening spice blend. 
  • Chili powder & cayenne pepper. Chili powder is my secret ingredient -- it adds warm, earthy flavor. Cayenne pepper brings a spicy kick, so adjust it to your taste. Start small if you're sensitive to heat.
  • Salt & black pepper. Reduce the salt if you're watching your sodium or plan to heavily salt your dish.

🫐Variations or Substitutions

  • White pepper. Swap out black pepper for white pepper for a more subtle pepper flavor. 
  • Sugar. For a sweet twist, add brown sugar or granulated sugar to the Cajun spice blend. I leave it out of the base blend, then stir some in when I want a sweet-and-spicy flavor. 
  • Dry mustard. For a little tangy, pungent flavor.

🥣How to Make Blackened Cajun Seasoning

🎁Storage

Store blackened Cajun seasoning in a covered jar in a cool, dry place for up to 6 months. For best flavor, use within 3 months.

❓FAQ

What's the difference between Cajun and blackened seasoning?

Both come from Cajun cuisine and bring bold, spicy flavor. Cajun seasoning tends to be a bit spicier and is a go-to for everyday Cajun cooking, while blackened seasoning is made for high-heat searing and usually includes key ingredients like paprika, thyme, and oregano to create a flavorful, spicy crust.

How spicy is blackened cajun seasoning?

It has a moderate kick from the cayenne and chili powder. You can reduce the cayenne for a milder version or bump it up for extra heat.

How should I use Cajun seasoning?

Rub this amazing blackened seasoning mix on your favorite chicken, fish, or shrimp recipes to create a bold, spicy crust-whether you're grilling, pan-searing, or baking. It's also great sprinkled on roasted vegetables, fries, or stirred into dips and sauces.

How long does it last?

Store blackened Cajun seasoning in an airtight container in a cool, dry space away from high temperatures. It has a shelf life of up to 6 months, but for best results, use within 3 months.
