What Exactly Is Blackened Seasoning?
Blackened seasoning isn't about burning your food—it's about building layers of flavor. This iconic Louisiana creation typically combines paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, salt, and black pepper. The magic happens when the seasoning caramelizes on high heat, forming a rich, smoky crust.

The Secret Behind That Smoky Crust
The hallmark of blackened fish is its dark, aromatic crust—achieved by searing the fish in a super-hot cast iron skillet. The seasoning doesn’t just stick; it bonds with the surface of the fish through Maillard reaction (that’s science-speak for “flavor explosion”).
Top 7 Redfish Blackened Seasoning Tips
Ready to turn up the heat? Here are seven essential tips to make your redfish pop with flavor:
- Dry the Fish Thoroughly: Moisture is your enemy when you're aiming for that perfect blackened crust. Pat the fillets dry with paper towels before applying seasoning.
- Don’t Skimp on the Oil: Use a high smoke-point oil like canola or grapeseed oil to avoid bitter flavors during searing.
- Heat the Pan Until It Screams: Your skillet should be smoking slightly before adding the fish. If you’re not sweating yet, you’re not ready.
- Crank Up the Ventilation: You’ll create smoke—that’s normal! Turn on the exhaust fan or open a window. Or two.
- Let It Rest: Letting the fish rest for 2–3 minutes after cooking helps redistribute juices and enhances texture.
- Go Easy on Salt: Commercial blends often have plenty of sodium. Taste before salting further.
- Customize the Heat: Adjust the amount of cayenne or add chili flakes to match your spice tolerance.

Blackened vs. Cajun: A Spicy Showdown
Confused about the difference between blackened seasoning and Cajun spice? Here’s a quick comparison to clear things up:
Feature | Blackened Seasoning | Cajun Spice Blend |
---|---|---|
Main Use | Fish & shellfish | Meats & stews |
Heat Level | Moderate to high | Mild to very spicy |
Key Ingredient | Paprika, thyme | Pepper-based heat |
Application Method | Thicker coat for crust | Light dusting |
Typical Result | Dark charred crust | Spiced but lighter finish |
Pairing Suggestions: From Wine to Sides
To balance out the richness and spice, opt for light, fresh sides and crisp wines:
- Sides: Mango salsa, lemon rice, grilled asparagus, or coleslaw with lime
- Beverages: Sauvignon Blanc, Pinot Grigio, or a citrus-infused IPA
- Optional Add-On: A squeeze of lime or dollop of crema to temper the heat

DIY Seasoning: Make It Your Own
Want full control over your flavor destiny? Whip up your own blackened seasoning mix:

Cooking Techniques for Perfect Crust
The method matters when it comes to blackening. Here's how to get that ideal char without overcooking the fish:
- Cast Iron Is King: It holds heat best for even browning.
- No Flipping Allowed: Cook on one side only unless the fillet is thick.
- Timing Is Everything: 3–4 minutes per side for medium-thick fillets.
- Aim for Medium Rare: Redfish stays juicy at medium-rare doneness.
