Spring Hill Ranch Korean-Style Grilled Tuna Steaks

Wiley P


We have a real difficult time here on the ranch with "tuna" from a can or the ubiquitous tuna casserole our mother used to make. We have found, however, that there is something very special to a lovely tuna steak, grilled to perfection over a hot grill. And when I say "to perfection," I mean cooked on the outside with lots of pink or red left on the inside.

This one includes a Korean-style marinade that can also be used as a basting sauce. Be careful with it, though, as marinating it too long will give you a mushy texture that you really don't want.

How to Make Spring Hill Ranch Korean-Style Grilled Tuna Steaks


  1. In a small mixing bowl or 2-cup measure, whisk together the soy sauce, sesame oil, sugar, sesame seeds, ginger, garlic, salt and pepper.
  2. Place the tuna steaks in a zip-lock bag and pour in the marinade, being sure each steak is coated. Seal the bag, refrigerate, and let the tuna marinate for 1 to not more than 1 1/2 hours, turning it occasionally. DO NOT OVER-MARINATE.
  3. Preheat your grill for high heat. Use a wire brush to make sure your grill is clean of any residue. Use tongs and paper towel to apply a liberal coating of vegetable or canola oil to the grill. You can either discard the marinade or place it in a small pan and boil it down a little to use as for a basting sauce.
  4. Grill the tuna for 1 1/2 to 2 minutes on each side. The "cooked" portion should extend only about 1/4" into the steak on each side, with pink and some red in the center. And trust me, the more red, the better. Please, oh please, do not over-cook this wonderful piece of tuna!
