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)

Directions

Step 1

Cut the tuna steak into 1-inch cubes, ensuring uniform size for even cooking.

Step 2

In a small bowl, combine Cajun seasoning, smoked paprika, salt, and black pepper. Mix well.

Step 3

Toss the tuna bites in the seasoning mixture until well-coated on all sides.

Step 4

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.

Step 5

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.

Step 6

Remove the tuna bites from the skillet and set aside on a plate lined with paper towels to remove excess oil.

Step 7

Prepare the Cajun mustard dipping sauce: In a small bowl, whisk together Dijon mustard, mayonnaise, lemon juice, and Cajun seasoning until smooth.

Step 8

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.
