Cajun Seasoning Recipe

This homemade Cajun seasoning blend is smoky, savory, bold, and packed with classic Louisiana-inspired flavor. Made with smoked paprika, celery salt, garlic, herbs, and cayenne, this easy spice mix is perfect for blackened chicken, seafood, fries, vegetables, and more.

If you cook any amount of Cajun food at home, having a reliable homemade Cajun seasoning recipe in your back pocket changes everything. This blend comes together in about two minutes, uses pantry staples you likely already have, and delivers more depth and better spice level control than anything from a store shelf.

This is honestly one of the most popular spice blends on my website and a personal favorite. I love it on my blackened chicken (watch the Instagram video that has had over 25 million views collectively), my Cajun ribs, and added to various Cajun or Creole dishes on my website. It’s also fantastic over veggies, on these country potatoes, and over popcorn.

Why This Recipe Works

• Smoked paprika as the base gives this blend a deep, slightly sweet foundation that regular paprika cannot replicate, and lets you dial up smokiness without adding liquid smoke.
• Double the heat sources using both cayenne pepper and red pepper flakes means you get layered heat that builds instead of one-note spice.
• Both garlic powder and onion powder round out the savory backbone, which is the signature of authentic Cajun cuisine from New Orleans and across the United States.
• You control the salt level because it is built in but adjustable, unlike most Cajun seasoning brands, where salt dominates the ingredient list.

Ingredients

The Spice Blend

• Smoked paprika (the bulk of this mix of paprika brings color and smokiness)
• Celery salt (a nod to classic New Orleans and Creole cuisine flavor profiles- if you don’t have this, use Kosher salt) 
• Garlic powder
• Onion powder
• Black pepper
• Dried oregano
• Dried thyme
• Cayenne pepper
• Red pepper flakes (this is what separates a great Cajun seasoning mix from a flat one)
• Mustard powder

Substitution Notes

• Salt-free version: Omit the celery salt. This works well if you are watching sodium or plan to use the blend on already-seasoned proteins.
• White pepper can replace half the black pepper for a slightly sharper, more peppery finish common in older Creole seasoning blends.
• Chile de árbol (finely ground) can swap in for part of the cayenne if you want more fruity heat with less raw burn.
• For more smokiness: Double the smoked paprika.
• For restaurant-style salt level: Increase the celery salt by half a teaspoon.

How to Make Homemade Cajun Seasoning

Step 1: Measure Your Spices

Add all spices to a small bowl or directly into a wide-mouth spice jar. Measuring each one before combining makes it easy to adjust on the fly if you want to increase the quantity of heat or decrease the quantity of salt before the final blend.

Step 2: Whisk or Shake to Combine

If using a bowl, whisk everything together until the spice blend is uniform in color. If using a jar, seal it and shake well for 20 to 30 seconds. No clumps, no uneven pockets of cayenne.

Step 3: Store and Use

Transfer to an airtight spice container and store in a cool, dry place. This Cajun spice blend keeps well for up to 6 months, though the spice level will be strongest in the first few months.

Tips and Variations

How much heat should you expect? As written, this blend lands at a medium spice level. It has a noticeable kick from both cayenne pepper and red pepper flakes, but it is not overwhelming. If you are sensitive to heat, start by reducing the cayenne to half a teaspoon and skip the red pepper flakes until you find your comfort level.

Scaling up: This cajun seasoning recipe scales easily. Double or triple the batch to keep a large jar on hand. A bigger batch stored properly tastes the same as a small one.

What to use it on: Beyond the Cajun food recipes on this site, this blend works on chicken wings, shrimp, salmon, roasted potatoes, fries, popcorn, burgers, and roasted vegetables. Any time you want bold, savory, slightly smoky heat, reach for this.

Why skip the best Cajun seasoning brands at the store? Most commercial options are heavy on salt and light on actual spice complexity. When you make your own, you get a full cajun seasoning blends experience without filler, free shipping gimmicks, or special offers clouding which product is actually good.

Creole vs. Cajun seasoning: People use these terms interchangeably, but there are differences. Creole cuisine from New Orleans tends to be more refined and often includes white pepper and more herbs. Cajun cooking is more rustic and paprika-forward. This recipe leans toward Cajun but pulls from both traditions, making it incredibly versatile across Cajun food and Creole cuisine dishes alike.
