Ingredients
- 2 tuna steaks, 180g (6.3 oz) each, 4 cm (1.6 inches) thick
- 30 ml (2 tbsp) extra virgin olive oil
- 2 cloves garlic, thinly sliced
- 1 lemon, cut into wedges
- 8 fresh basil leaves
- 4 sprigs fresh thyme
- 1 tsp sea salt
- 0.5 tsp black pepper
- 0.25 tsp dried red chili flakes
- 1 tbsp capers, drained
- 60 ml (0.25 cup) dry white wine
Instructions
-
Pat the tuna steaks completely dry with paper towels and season both sides evenly with sea salt and black pepper 2 minutes before cooking.
-
Heat 15 ml (1 tbsp) olive oil in a large stainless steel skillet over high heat until it shimmers and just begins to smoke, approximately 2 minutes.
-
Carefully place the tuna steaks in the hot skillet and sear without moving for 2 minutes until a golden brown crust forms on the bottom.
-
Flip the steaks and sear the opposite side for 2 minutes, then transfer to a warm plate to rest for 3 minutes.
-
Reduce heat to medium and add the remaining 15 ml (1 tbsp) olive oil to the same skillet along with sliced garlic, thyme sprigs, and red chili flakes.
-
Toast the garlic and herbs for 45 seconds until fragrant, then add the white wine and capers, scraping the bottom of the pan with a wooden spoon to deglaze.
-
Simmer the pan sauce for 1 minute until reduced by half, then tear in the fresh basil leaves and remove from heat.
-
Divide the rested tuna steaks between two plates and spoon the warm garlic-caper sauce over each steak, finishing with a squeeze of fresh lemon juice and a drizzle of extra virgin olive oil.
Substitutions
- Substitute capers with pitted green olives for a briny alternative with similar sodium content
- Replace white wine with vegetable broth for an alcohol-free pan sauce
- Use rosemary sprigs instead of thyme for a more robust Mediterranean herb profile
- Swap basil with fresh oregano to maintain Italian authenticity
Tips
- Purchase sushi-grade tuna and keep it refrigerated until the moment of cooking for optimal texture and safety
- Do not overcook tuna beyond 2 minutes per side—the interior should remain cool and translucent for best flavor and texture
- Use a heavy-bottomed stainless steel skillet rather than non-stick to achieve a proper golden crust through the Maillard reaction
- Bring all ingredients to room temperature 5 minutes before cooking to ensure even searing
