A Sizzling History Lesson

The story begins in the 1980s, when Louisiana chef Paul Prudhomme introduced the world to blackened fish. He wasn’t just cooking — he was performing culinary alchemy by searing seasoned fillets in a super-hot cast-iron skillet until they formed a smoky, crispy crust.
This technique and its signature seasoning quickly became a sensation across America. The seasoning itself is a bold mix of herbs and spices designed to withstand high heat while delivering layers of flavor that linger long after the first bite.

Pro Tips for Using Blackened Seasoning Like a Chef
Using blackened seasoning isn't just about slapping it onto fish and hoping for the best. Here are some tried-and-tested tips that will take your dishes from good to *“Wait…did I really make that?”*
- Use a Cast-Iron Skillet: It holds heat better than any other pan, which is essential for achieving that signature blackened crust.
- Don’t Overseason: A thick layer of seasoning helps create the crust, but too much salt can overpower the dish.
- Pat Dry First: Moisture is the enemy of the blackening process. Dry your protein thoroughly before applying the seasoning.
- Use High Smoke-Point Oil: Canola or grapeseed oil works best for getting that perfect sear without burning.
- Open Windows or Turn On the Fan: It gets smoky in here — literally!
- Rest Before Serving: Letting the fish rest for 5 minutes ensures juices redistribute evenly.
