Blackening is a crust, not a burn. The pan has to be genuinely hot and the tuna comes out rare in the middle — that's the whole point of buying good tuna.
Ingredients
For the tuna
- 1 lb yellowfin tuna steak, cut into 1-inch thick steaks (about 4 pieces)
- 2 tbsp olive oil
- 2 tbsp blackening seasoning, store-bought or homemade
- 1/2 tsp sea salt
- 1/2 tsp black pepper
- 1 tbsp lemon juice
Homemade blackening seasoning (optional)
- 1 tbsp paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp dried oregano
- 1/2 tsp dried thyme
- 1/2 tsp cayenne pepper, adjust to taste
- 1/2 tsp salt
- 1/2 tsp black pepper
Preparation
- Pat dry. Paper towels, both sides.
- Season. Brush with olive oil, then coat all sides generously with blackening seasoning, pressing it to adhere.
- Heat the pan. Heavy skillet — cast iron is best — over medium-high until very hot.
- Cook. 1 1/2–2 minutes per side for rare. Outside blackened, inside pink and tender.
- Rest. 3 minutes off the heat.
- Finish. Squeeze lemon over before serving.
Serving
Serves 2–4. Rice and a chopped cucumber-tomato salad works well against the heat.
Pro tips
- Turn the extractor on and open a window. This smokes. That's normal.
- Cast iron holds heat through the sear — nonstick can't get hot enough and won't blacken.
- Two minutes a side, maximum. Cooked through, this is an expensive tuna sandwich.
- The rest matters. Slice straight off the heat and the juices run out onto the board.
- Slice against the grain, in thick pieces.
