Recipe Information
Ingredients
- 1 pound fresh tuna steak
- 2 tablespoons Cajun seasoning
- 1 teaspoon smoked paprika
- 0.5 teaspoon salt
- 0.5 teaspoon black pepper
- 2 tablespoons olive oil
- 2 tablespoons Dijon mustard
- 2 tablespoons mayonnaise
- 1 tablespoon lemon juice
- 0.5 teaspoon Cajun seasoning (for sauce)
- 1 teaspoon fresh parsley (optional, for garnish)
Instructions
Cut the tuna steak into 1-inch cubes, ensuring uniform size for even cooking.
In a small bowl, combine Cajun seasoning, smoked paprika, salt, and black pepper. Mix well.
Toss the tuna bites in the seasoning mixture until well-coated on all sides.
Heat olive oil in a large skillet over medium-high heat. Once hot, add the tuna bites in a single layer, being careful not to overcrowd the pan.
Sear the tuna bites for 1-2 minutes on each side, depending on your preferred doneness. Aim for a slightly crisp exterior while keeping the center tender and pink.
Remove the tuna bites from the skillet and set aside on a plate lined with paper towels to remove excess oil.
Prepare the Cajun mustard dipping sauce: In a small bowl, whisk together Dijon mustard, mayonnaise, lemon juice, and Cajun seasoning until smooth.
Transfer the tuna bites to a serving platter. Garnish with fresh parsley, if desired, and serve immediately with the Cajun mustard dipping sauce on the side.
