  1. 1

    Prepare the Ahi Tuna

    Pat the Ahi tuna steaks dry with a paper towel. Season both sides with Cajun seasoning, salt, and black pepper.

    In a large skillet, heat the olive oil over medium-high heat until shimmering.

  3. 3

    Blacken the Tuna

    Add the seasoned Ahi steaks to the skillet and cook for about 2-3 minutes on each side until they develop a blackened crust and are cooked to your desired doneness.

    Make the Spicy Soy Mustard Sauce

    In a small bowl, whisk together the soy sauce, Dijon mustard, and lemon juice until well combined.

  5. 5

    Prepare the Butter Sauce

    In a small saucepan, melt the butter over low heat. Stir in the green onions and cook for about 1 minute until fragrant.
