Blackened Tuna Recipe. Whole blackened tuna steak or blackened tuna bites.

Have you ever made something you think is so simple and then people go nuts for it?  This fresh tuna recipe is one of those.

It is so funny that you can spend 2 hours on a dish and think it is going to be a hit. Then meh, no one really says anything. But then, you throw something together in 10 or 20 minutes and its talked about and requested for years!  Am I right? What the heck people, lol! 

Another one of those easy recipes that is always a hit and the recipe is asked for is this Hot Onion Dip. Minutes to assemble with items almost always on-hand and inexpensive to make. People go crazy, ha!

How to make Blackened Tuna Bites

These Blackened Tuna Bites simple yet amazing. The better the tuna, the better the bite! You can also keep the fish whole and make Blackened Tuna Steak. If tuna is a favorite, you have to try Spicy Tuna with Crispy Rice, my children and niece all say its on of the best things they have ever tasted (which makes me happy!)

So many people have asked how to make them or asked to have me make them for them ever since. I personally must have sold a ton of Blackened Redfish Magic by Paul Prudhomme (which is the seasoning I usually use on this).

Ingredients to make Blackened Tuna

  • Fresh tuna steaks
  • Blackening seasoning (my favorite is Blackened Redfish Magic)
  • Oil for cooking such as Avocado or Olive oil

Variations

  • Instead of making tuna bites, you can keep the tuna steaks whole and make blackened tuna steaks as an entrรฉe.
  • Swap blackening seasoning for Cajun seasoning. Similar, Cajun just had more of a kick.

Tips

  • The better the quality and freshness of your tuna steaks, the better the taste.
  • Coat the tuna after cutting into chunks, coating well to toss.
  • Use a nonstick skillet.
  • Heat the pan, add the oil, once oil is hot add tuna. Use tongs to gently move each piece so that all sides get a quick sear.
  • Cook to your preference of medium, well done or more on the rare side (again quality tuna comes into play if you opt for more rare).

Which Seasoning should I use?

For the Tuna Bites I swear by Chef Paul Prudhomee Blackened Seafood Blackened Redfish Seasoning and I use it for this, however any Cajun seasoning will work.

You can call these blackened tuna bites or spicy tuna bites, I call them de-lic-ious!

  1. I took a seafood grilling class last night at the Viking Cooking School in Atlantic City. I wish these had been on the menu. They look amazing!

  2. Go ahead and add me to your list of people who go CRAZY over a simple delicious recipe. I made these tonight and they were ahhhmaaazing! Simple, quick, easy, delish! And thanks for turning me onto Chef Paul's Seafood Magic, I will be making these again and again and again.....

  3. I made these with cilantro lime infused olive oil. Wonderful! Best tuna I have ever had! I put the cubes on skewers and grilled them on a grilling mat. Seasoning was Slap Your Mamma on two sides of the cubes. They were so good that I didnโ€™t even use the sauce (which is also good).

    1. Hi Tracy, YOu could warm them up the following day and/or enjoy them on a salad however in my opinion they are best freshly made.
