What “Blackened” Means

Blackening is a classic Louisiana cooking technique popularized in New Orleans. The fish is coated in a bold spice blend and cooked in a very hot skillet, creating a flavorful, slightly smoky crust.

The outside develops that signature dark char while the inside stays flaky and tender.

How to Make Blackened Fish Tacos

1. Prepare the Spice Blend

Mix all spices together in a small bowl.

2. Season the Fish

Pat fish dry and brush with olive oil. Coat generously with the blackening seasoning.

Let rest for a few minutes, then flake into chunks.
