These marinated and grilled tuna steaks cook up quickly on an indoor grill, whether an electric model or a grill pan. They're easy enough for a weeknight but special enough for company and are quick and easy to make.  If you like your grilled tuna very rare (as I do), be sure to buy it as fresh and of as high quality as possible, from a reputable fishmonger. If you're new to indoor grilling, be sure to check out my Indoor Grill Cooking Tips.

Tip: To easily prepare the fresh ginger, use the edge of a spoon to scrape the peel off a knob of ginger and grate it with a microplane grater or the fine grating blades of a box grater. Or, opt for jarred grated ginger, sold in the Asian section of supermarkets.

Cooking Equipment Needed: Liquid measuring cup, chef's knife, cutting board, measuring spoons, citrus juicer, countertop grill or grill pan, tongs, small saucepan, whisk.

What You'll Need

  • 1/2 cup low-sodium soy sauce
  • 1/4 cup chopped scallions, white and light green part
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon sesame oil
  • 1 teaspoon grated fresh ginger
  • 4 tuna steaks, about 6 ounces each
  • 1/2 cup sesame seeds, white and black combined, or white only
  • 1/2 teaspoon cornstarch

How to Make It

  1. In a large zip-top bag, combine the soy sauce, chopped scallions, lemon juice, sesame oil and fresh ginger. Swish everything around in bag until it's combined. Add the tuna steaks, turning within the bag to coat them completely with the marinade. Press the excess air of the bag, seal, and marinate in the refrigerator for about 20 minutes.
  2. Preheat a countertop contact grill to "Sear" or the highest temperature setting. Place the sesame seeds on a plate or a shallow dish. Remove the tuna steaks from marinade bag, brushing the scallions off the steaks and reserving the marinade. One at a time, coat the steaks in sesame seeds on all sizes, pressing the seeds into the steak so they'll stick.
  1. Spray the grill plates lightly with nonstick spray and place the steaks on the grill, closing the cover so the top grill rests evenly on the steaks. Do not press down. Grill for about 3 minutes (longer if you prefer your tuna cooked through). Remove from grill and keep warm. If you are using an open grilling surface, carefully flip the tuna steaks with a pair of tongs after 3 minutes and cook for 3 minutes on the other side.
  2. Meanwhile, pour the marinade into a small saucepan and bring to a boil. Add the cornstarch, stirring with a whisk. Cook for about 3 to 4 minutes, until the sauce thickens.
  3. To serve, slice the tuna steaks on the diagonal into thin slices. Fan the slices on a plate and drizzle with the sauce.
