Nutrition (per serving)
Method
Slice the tomato into thin, even rounds and separate the butter lettuce leaves. Set the produce aside.
Slice the french baguette in half lengthwise. Lightly toast the cut sides until crisp and golden brown.
Thoroughly pat the tuna steaks dry with paper towels to ensure a good crust. Rub all sides with olive oil and season evenly with kosher salt and black pepper. Wash your hands and any surfaces that contacted the raw fish immediately after to prevent cross-contamination.
Heat a dry skillet over high heat until smoking hot. Sear the tuna steaks for 1 to 2 minutes per side. For a rare center, the internal temperature should reach 45°C or 115°F.
Transfer the seared tuna to a clean cutting board and let it rest for 3 minutes to allow the juices to redistribute.
Using a sharp chef knife, slice the rested tuna thinly against the grain.
Spread the black olive tapenade evenly on the bottom half of the toasted baguette. Layer the butter lettuce over the tapenade to create a moisture barrier, followed by the tomato slices and the sliced seared tuna. Top with the remaining baguette half, press down gently, and cut the sandwich in half to serve.
Chef's Notes
- Using a high quality, sushi-grade tuna is essential since the center of the fish will remain raw.
- Patting the tuna completely dry before searing ensures a proper crust forms rather than steaming the fish in its own surface moisture.
- Slicing the tuna against the grain shortens the muscle fibers, resulting in a much more tender bite that is easier to eat in a sandwich format.
- To elevate store-bought tapenade, stir in a squeeze of fresh lemon juice and a few chopped capers for added brightness and acidity.
Storage
Refrigerator: 24 hours — Store components separately. Assembled sandwiches will become soggy and do not keep well.
