Bluefin Tuna with Olive, Cucumber, and Cilantro Relish


This recipe is courtesy of Lost Kitchen chef and owner, Erin French.


  • 3 Kirby cucumbers
  • 1/2 cup pitted mixed olives, cut into a 1/4-inch dice
  • 1/4 cup packed fresh cilantro leaves
  • 2 Tbsp fresh lemon juice, plus lemon wedges for serving
  • 1/4 cup plus 2 tablespoons extra-virgin olive oil
  • Coarse salt and freshly ground pepper
  • 2 Tbsp unsalted butter


  1. Halve cucumbers lengthwise, scoop out and discard seeds, then cut cucumbers into a 1/4-inch dice.
  2. In a small bowl, combine cucumbers, olives, cilantro, lemon juice and 1/4 cup oil; season with salt and pepper. Set aside.
  3. Season tuna steak with salt and pepper. Heat a large, heavy skillet (preferably cast-iron) over high. Add 2 Tbsp oil; when it begins to shimmer, add tuna steak. Sear 1 minute, then flip and cook 30 seconds more. Add 2 Tbsp butter, melt, and cook 1 minute more. Note: we like our tuna cooked rare, if you prefer it cooked more medium feel free to add a couple minutes to your cook time.
  4.  Using a sharp knife cut tuna steak along the bias and serve topped with olive relish.
