Ingredients
Scale
Tuna Preparation
- 2 x 180 – 200g (6.5 – 7oz) tuna steaks (skinless, boneless, 2.5-3cm / 1-1.2″ thick)
- 1 tsp olive oil
- 1/4 tsp sea salt
- 1/8 tsp black pepper
- 2 tsp olive oil or oil spray (for skillet)
Sauce Vierge
- Sauce Vierge (French salsa/vinaigrette for fish)
- Chervil sprigs or small flat leaf/curly parsley leaves (optional)
- Small edible flowers (optional)
Instructions
- Prepare resting tray: Place a wire rack on a tray to rest the tuna steaks after cooking. This allows air circulation and helps the tuna cool evenly without sogginess.
- Oil and season tuna: Drizzle half of the olive oil over the tuna steaks. Smear the oil evenly over one side, then sprinkle with half the sea salt and black pepper. Flip each steak and repeat the oil and seasoning on the other side to ensure even flavor.
- Heat skillet: Preheat a skillet, preferably one with grill lines, over high heat until it is smoking hot. A very hot pan is essential to achieve searing and attractive grill marks.
- Oil skillet (if required): If your skillet is not well-seasoned, lightly brush the surface with olive oil or remove it from the heat and spray with oil. Be cautious to avoid flare ups or smoke inhalation during this step.
- Cook first side: Place one tuna steak in the skillet and cook for exactly 45 seconds without moving it to allow searing and grill lines to develop. Repeat one steak at a time for best results.
- Rotate for grill lines: Turn the steak 45 degrees and continue cooking the same side for another 45 seconds to create cross-hatched grill marks.
- Cook other side: Carefully flip the tuna steak and cook the second side for one minute or until the internal temperature reaches 48°C / 118°F for rare doneness.
- Rest: Transfer the tuna from the skillet onto the prepared wire rack. Allow it to rest at room temperature for 5 minutes to cool slightly and make slicing easier, preserving the texture and flavor.
- Plating up with Sauce Vierge: Place the tuna steaks on a serving board or plate with the criss-cross grill lines facing up.
- Slice, if desired: Using your fingers to support the edges to prevent crumbling, slice the tuna into 4-5 thick pieces. Arrange the slices on the plate slightly angled or separated so the rare interior is visible.
- Sauce Vierge: Spoon the Sauce Vierge over the tuna slices, making little piles of tomato and vinaigrette on the fish and plate to add fresh acidity and sweetness.
- Finishing touches: Drizzle a little more olive oil over the plated tuna, then garnish with chervil sprigs and edible flowers for an elegant presentation.
Notes
- Use fresh, high-quality tuna steaks about 2.5-3cm thick for optimal searing and texture.
- Sauce Vierge is a tangy French salsa made with olive oil, fresh tomatoes, herbs, and lemon juice—perfect for seafood.
- Allowing the tuna to rest on a wire rack prevents sogginess and lets it cool to room temperature, making it easier to slice.
- Be cautious when oiling a hot skillet to avoid flare-ups or burns; it’s safer to oil before heating or immediately after removing from heat.
- Cooking one steak at a time ensures proper searing and temperature control.
- Use a thermometer to check tuna internal temperature for precise doneness; 48°C / 118°F yields rare, moist tuna.
- When slicing, hold the edges gently to avoid breaking the seared surface, preserving the beautiful crust and texture.
