This is a really simple recipe, which is a good thing, but because of the simplicity, how it "turns out" depends largely on the quality of your ingredients. I bought a cheap piece of tuna and us...

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 ...

This recipe was great. It was my first time making fresh tuna and I will make it again. I sprayed the pan with olive oil flavored spray to reduce calories and fat, then added the butter.

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...

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...

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 ...

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!
