What Exactly Is Cajun Seasoning?
Cajun seasoning hails from Louisiana, baby! It’s that bold, zesty blend that gives dishes like crawfish étouffée and spicy jambalaya their signature kick. But here’s the thing: it’s more of a flavor profile than a fixed recipe. That means no two brands (or chefs) will have the exact same mix.
Traditional Cajun seasoning usually includes:
- Paprika
- Cayenne pepper
- Garlic powder
- Onion powder
- Black pepper
- Salt
- Oregano
- Thyme

Gluten 101: What Are We Talking About?
Before we answer 'Is Cajun seasoning gluten free?', let's break down what gluten actually is. Gluten is a protein found in wheat, barley, rye, and triticale. For people with Celiac disease or gluten sensitivities, even tiny amounts can cause discomfort, digestive issues, or long-term health problems.
Now, most individual spices like paprika, garlic powder, and black pepper are naturally gluten-free. But here's where things get tricky: some seasonings may contain fillers, anti-caking agents, or other additives that could sneak in gluten.
Is Cajun Seasoning Gluten Free? The Big Reveal
Here’s the short answer: It depends. While many basic Cajun seasonings are gluten-free, store-bought versions can sometimes include wheat-based additives or be processed in facilities that handle gluten-containing products.
So yes, there’s a chance your favorite Cajun seasoning might not be as gluten-free as you think. And if you’re sensitive, that’s a big deal.

How to Read Labels Like a Pro
Label reading is an art—and when it comes to avoiding gluten, you want to master it. Here’s how to play detective in the spice aisle:
- Look for the words 'gluten-free' on the label—bonus points if it's certified.
- Scan the ingredient list for red flags like wheat, barley, rye, or malt.
- Check allergen statements, usually near the end of the packaging. If it says “Contains: Wheat,” steer clear.
- Beware of ‘natural flavors’ or ‘spices’ without specifics—they could hide gluten.
