Grilled Yellowfin with Mango-Papaya Relish

Grilled yellowfin tuna is at its best when you keep the cooking simple and let the fish itself do the talking. A quick rub of ground coriander, oil, salt, and white pepper is all the seasoning the steaks get before they hit the grill. The interior should stay pink and tender, like a rare steak, while the outside develops a quick char crust.

The relish is the show. Half the fresh mango and papaya get pureed into a smooth golden base while the rest stays in small dice for texture and visible color. A splash of lemon juice keeps the fruit bright, and cilantro pulls it into clear tropical-Asian territory. Spoon a generous puddle on the plate next to the tuna so each bite gets a forkful of both. The cool sweet-tart fruit plays against the meaty char of the grilled fish.

Pro Tips

• Use sushi-grade or sashimi-grade tuna if you want it rare in the center. Lower grades should be cooked through for safety.
• Pat the steaks dry before oiling. Wet tuna steams instead of searing on the grill grates.
• Get the grill screaming hot before adding the tuna. Cool grates produce grey, overcooked fish before any crust can form.
• Grill 1 to 2 minutes per side for rare, 3 to 4 minutes for medium. Yellowfin overcooks fast and turns dry.
• Make the relish at least 30 minutes ahead so the flavors mingle, but pull it from the fridge 10 minutes before serving so it is not painfully cold against the hot fish.

Variations

• Use pineapple and mango in place of papaya for a different tropical fruit profile.
• Add minced jalapeno or red pepper flakes to the relish for heat.
• Swap the tuna for halibut, salmon, or mahi-mahi for a different fish under the same relish.
