Quick answer

To make blackening seasoning, whisk two tablespoons of paprika with one tablespoon each of garlic powder and onion powder, two teaspoons of cayenne, one teaspoon each of dried thyme, dried oregano, salt, black pepper, and white pepper. To use it: dip fish or chicken in melted butter, coat heavily, and sear in a dry cast iron pan hotter than feels reasonable.

What it is

What is blackening seasoning?

Blackening is a technique wearing a seasoning's name. The blend itself is close kin to Cajun and Creole shakers, paprika in the lead, real cayenne presence, garlic, onion, herbs, and two dark peppers. What makes it blackening seasoning is the method it was built for: the protein is dipped in melted butter, coated thickly, and dropped into a dry cast iron pan at maximum heat, where the butter and spices cook instantly into a near-black, deeply savory crust while the inside stays just done.

The crust is not char. It is milk solids browning and spices toasting in the same violent instant, which is why the color is mahogany-black and the flavor is toasted, not bitter. The technique demands honesty about heat: a merely hot pan steams the coating into wet spice paste. This is a preparation for an open window, a roaring vent, or better yet, an outdoor burner.

The recipe

What goes in blackening seasoning?

2 tbsp
Paprika
×
1 tbsp
Garlic powder
×
2 tsp
Cayenne
×
1 tsp each
Thyme + oregano

Paprika at the top and cayenne at a full two teaspoons, this blend is supposed to arrive hot. The thyme and oregano toast into the crust, and the three-pepper spread, cayenne, black, white, is straight from the Louisiana playbook.

Method

How do you make blackening seasoning?

  1. Whisk everything together and jar it sealed. Good for four months.
  2. Heat a dry cast iron pan over high until it just begins to smoke, ten minutes on a home burner is not too long.
  3. Dip fish fillets, chicken breast pounded even, or shrimp in melted butter.
  4. Press the seasoning on generously, both sides, a full coat, not a dusting.
  5. Sear two to three minutes per side for fish, until the crust is deep brown-black and the inside just cooked. Expect drama and smoke, that is the technique working.
Blackened, not burnt The line between the two is what is browning. In blackening, butter solids and spices toast at high speed into a crust that tastes deep and savory. Burnt is what happens without the butter dip or with a pan left past smoking into scorching. The butter is the safety and the flavor at once.
Cook's notes

What should you know before making blackening seasoning?

History

Where did blackening seasoning come from?

Blackening belongs to Paul Prudhomme, whose blackened redfish at K-Paul's Louisiana Kitchen in New Orleans became one of the defining restaurant dishes of the 1980s. The craze ran so hot that Gulf redfish stocks buckled under demand and regulators moved to restrict the catch. The technique survived on other fish and on chicken, and the spice blend became a permanent American shelf item.

FAQ

Common questions.

What is the difference between blackening and Cajun seasoning?

The jars overlap heavily, paprika, cayenne, garlic, herbs. Blackening seasoning is really defined by its technique: butter dip, heavy coat, and a nearly smoking cast iron pan. Any good Cajun or Creole blend can blacken if used that way.

Why did my blackened fish come out soggy instead of crusted?

The pan was not hot enough. Blackening needs cast iron at the edge of smoking so the butter and spice coat sets instantly. A medium-hot pan steams the coating instead. Preheat longer than feels polite.

Can I blacken without cast iron?

Cast iron or carbon steel, yes, nonstick, no. Nonstick coatings cannot take the temperature this technique requires. If neither pan is available, use the same blend under a broiler set high, close to the element.
