For the Blackened Ahi Tuna

For the Wasabi Mashed Potatoes

For the Ponzu Butter

Method

Preparation

  1. 1

    Prepare the Wasabi Mashed Potatoes

    Peel and chop the russet potatoes, then boil them in salted water until tender. Drain and return to the pot. Add butter, heavy cream, wasabi paste, and salt. Mash until smooth and creamy. Keep warm.

  2. 2

    Make the Ponzu Butter

    In a small saucepan, melt the butter over low heat. Stir in ponzu sauce and chopped green onions. Heat gently until warm and combined. Remove from heat.

Cooking the Ahi Tuna

  1. 3

    Sear the Tuna Steaks

    Pat the tuna steaks dry and coat both sides with Cajun seasoning. Heat olive oil in a skillet over high heat. Once hot, add the tuna steaks and sear for about 1-2 minutes per side for medium-rare, adjusting time for desired doneness. Remove from heat.

Serving

  1. 4

    Plate the Dish

    On each plate, place a generous scoop of wasabi mashed potatoes, top with the blackened ahi tuna, and drizzle the ponzu butter over the top. Serve immediately.
