I first had blackened tuna a few weeks ago at a buffet in a casino. I am not sure how this was my first time since I have lived in Louisiana for 24 years but it was. Well as soon as I got home...

This was really simple, easy, and, most importatly, absolutely delicious! Warning though: open up your windows and turn off the smoke detectors when cooking this because it does get smokey.

Great recipe. You can also make on the gas grill by using a black iron skillet. Heat the skillet on medium heat for 15 minutes. Half the butter/oil and pour a small amount in skillet. Season ...

I buy the blackening seasoning from the fish market, but have tried both and either way is very good! Although, a small suggestion...Make this on the grill! If you enjoy the air quality in you...

Husband loved it! More salty than spicy, so I think next time I will add cayenne and garlic powder to the Cajun/Creole seasoning to bring up the flavor without over-salting.

We love to make sashami grade tuna this way. (just about every time it's on sale!) It's so quick and delicious. Just a quick tip- get the Cajun seasoning without salt that way you can use lots ...

Fantastic!!! We like our tuna medium rare so we cooked for 2 to 2 1/2 mins. per side and turned out wonderful. Served with black beans and rice and a salad. We will be making this many more ti...

Exceptional! My favorite tuna steak recipe. I use enough cajun seasoning to generously cover the steaks... I don't go by the 2 TBSP. Yummy!
