Blackening is a technique, not just a seasoning - it's about a pan hot enough to char the spice crust nearly black in under three minutes without cooking the inside past medium. That means real heat, more than most home stoves are comfortable putting out. If you can do this over an open flame or an outdoor burner, do it there instead.
What you need
- 2 redfish fillets, skin off, patted bone dry
- 3 tbsp Gulf Coast Blackening
- 2 tbsp neutral oil
- 4 tbsp unsalted butter
- Lemon wedges, to serve
How it goes
- Pat the fillets completely dry - any surface moisture steams the fish instead of blackening it.
- Coat both sides heavy in Gulf Coast Blackening, pressing it in so it forms a real crust, not just a dusting.
- Get a cast iron skillet properly smoking hot over high heat with the oil, well past the point that feels comfortable - this is not a recipe for a timid burner.
- Lay the fillets in dry, away from you. Do not move them.
- Sear 2 to 3 minutes until a dark crust forms, then flip.
- Once flipped, drop the butter into the pan around the fish and let it melt and start to brown - butter after, never before, or you're blackening burnt fat instead of the blend.
- Baste with the browned butter for the final minute, then pull and serve with lemon. The fillet should read 130-135F internal and will finish carrying over off the heat.
Worth knowing
- Crack a window or take this one outside. There is no version of proper blackening that doesn't make smoke.
- This technique works the same on chicken breast or shrimp if redfish isn't available - same heat, same timing adjustments for thickness.
- A thin metal spatula makes the flip cleaner than a thick one, which can tear the crust.
Pit note. It's the blend that blackens, not the fat. Butter goes in after the flip, not before.
