Grilled Tuna with Mint Viniagrette

Fresh tuna steaks need very little help, and this mint vinaigrette knows exactly when to step back and when to shine. The vinaigrette is built from extra-virgin olive oil, fresh lime juice, white wine vinegar, diced Roma tomatoes, minced shallots, and blanched garlic, with chopped mint tying it all together in a bright, herbaceous finish.

Blanching the garlic before mincing is a subtle but smart move. Raw garlic would overpower the delicate mint and tuna, but a quick blanch mellows it just enough to blend into the vinaigrette without disappearing entirely.

The tuna grills about four minutes per side. For steaks with a seared exterior and a pink center, don’t go longer. Overcooked tuna turns dry and chalky fast.

Pro Tips

• Let the tuna come to room temperature for 15 minutes before grilling. Cold fish sticks to the grate and cooks unevenly.
• Oil the tuna, not the grill. A light coat of olive oil and pepper directly on the steaks prevents sticking.
• Make the vinaigrette while the tuna chills so the flavors have time to meld before serving.
• Spoon the vinaigrette over the tuna at the table, not in the kitchen. It looks better and the herbs stay vibrant.

Variations

• Mix chopped fresh basil with the mint for a more complex herbal flavor.
• Swap lime juice for lemon juice and add capers for a Mediterranean direction.
• Serve the vinaigrette alongside seared salmon or grilled swordfish instead of tuna.
