Tuna Au Poivre With Roasted Garlic And Corn Mashed Potatoes

  • Yield: 4 servings


  • 1 pound of Yukon Gold Potatoes, washed and quartered
  • Pinch of salt
  • 3 tablespoons butter
  • 1/2 cup heavy cream
  • Freshly ground pepper
  • 1/4 cup roasted garlic
  • 1 ear of corn, grilled or roasted, kernels removed from the cob
  • 4 (10 to 12 ounces) tuna steaks, trimmed
  • Salt
  • 1 cup black peppercorns
  • 1/2 cup plus 1 tablespoon Dijon mustard
  • 2 tablespoons olive oil
  • 1 tablespoon finely chopped fresh parsley leaves


  • Place the potatoes in a saucepan, cover with water and cook over medium-high heat. Season with salt. Bring to a boil, reduce to medium heat and cook until tender, about 12 minutes. Remove and drain. Place the potatoes back in the saucepan over medium heat. Continue to cook for 1 minute, stirring constantly. Add the butter and cream. Using a hand masher, mash until the potatoes are slightly smooth. Season with salt and pepper. Add the garlic and corn. Mix well. Set aside and keep warm. Season the tuna with salt. In a coffee grinder, add the peppercorns and coarsely grind. With a small knife, spread a tablespoon of mustard on one side. Pack the peppercorns into the steak. Turn the tuna over and spread another tablespoon of mustard. Pack the peppercorns into the tuna on the second side. Heat the oil in a large skillet over medium heat. When the oil is hot, add the tuna and sear for 2 to 3 minutes on each side for medium-rare. Place a mound of the potatoes in the center of each plate. Place the tuna on top of the potatoes. Garnish with parsley.
