How To Make Grilled Tuna Steak Recipe Bobby Flay


  • Fresh flat-leaf parsley: ¼ cup, chopped
  • Fresh ginger: 1 tuber
  • Canola oil (or extra virgin olive oil)
  • Kosher salt
  • Clover honey: 2 tablespoons
  • Tuna: 4 fillets

To keep its inner meat relatively cool, let’s take the tuna out of the refrigerators for about 20 minutes before cooking. 


First, brush the canola oil (or olive oil) on either side of the tuna and season with salt. Then, cook the tuna on the grill (or pan) until its color turns to yellowish-brown and charred on the bottom (about 4 minutes). Next, turn the tuna over, brush it with some oil, and continue cooking for one or two minutes. 

After that, prepare the plates, spray a bit of green peppercorn dressing, and put the tuna fillets on them. Finally, use parsley sprigs and golden-brown fried onion rings to add more flavors and colors to your steaks. For a sweet and spicy flavor, you sprinkle the pink peppercorn on those plates.

A few tips for you when choosing tuna

  • High-quality tuna will range in color, from pink to deep red. If your store displays thinly sliced steaks, look for shiny pieces, about an inch thick, moist, and almost translucent. 
  • Tuna that looks flaky, dry, dull, or brown on the edges will not be fresh. Fresh tuna will have a fresh sea-air smell, and it is moist in appearance, but not overly wet.
  • Let’s store your tuna on the bottom shelf of your refrigerator until you’re ready to use it because it dries out quickly. 
  • Tuna will taste best from May to September when they are in season.
  • You can buy frozen tuna instead of raw tuna to save money.
