Blackened tuna is a quick flavorful preparation that is great served on its own or served over salad or your favorite veggies. The spicy crust is a flavor bomb in every bite.
How to Sear Blackened Tuna
Blackened Tuna Steaks are one of my favorite ways to prepare tuna. The charred spicy outer crust and the tender rare center are the perfect flavor and textural contrast. Blackened tuna is seared at very high heat in a pan or on a grill using clarified butter (ghee) or a high smoke point oil like avocado oil.
Unlike beef you want to keep the tuna refrigerated until it’s time to sear. you want the tuna to be as cold as possible so you can keep the center rare and develop a crust on the outside. Ensure the pan is hot before adding the oil and seasoning the tuna.
Seasoning Blackened Tuna Steaks
You can use Cajun or Blackening seasoning to season your tuna steaks. Both contain a lot of salt, but I still recommend seasoning liberally so you get the best crust. My absolute favorite seasoning to use for blackening fish is Chef Paul Blackened Redfish Magic. It has the best flavor and spice level, in my opinion.
Best Pan For Searing Blackened Tuna Steak
I am a big fan of using carbon steel pans for high-heat searing. Cast iron also works well, but I find they take a while to heat up. Carbon steel gives you the searing ability but takes a fraction of the time to heat up and cool down. Avoid searing with a nonstick pan due to the fact that they are not designed for high-heat cooking.
Slicing Tuna Steaks
Having a sharp knife is probably the most important thing when slicing tuna. Before slicing, sharpen your knife using honing steel or a handheld knife sharpener. After you sharpen the knife, wipe it off with a damp cloth before slicing. Make small, even slices cutting across the grain of the tuna steak. I also recommend letting the tuna rest for just a minute or two once you have removed the tuna from the pan.
