Sesame-Crusted Tuna Steak

This sesame-crusted tuna is all about contrast: crisp nutty crust outside, tender rare centre inside. It cooks in minutes, making it ideal for a fast but impressive dinner with rice, greens or a sharp salad.

Method

15m5m20m
  1. Pat the tuna steaks dry and season lightly with salt and pepper.
  2. Mix soy sauce, lime juice, sesame oil, ginger and garlic in a shallow dish. Coat tuna lightly, then leave for 10 minutes.
  3. Combine black and white sesame seeds on a plate. Press each tuna steak into the seeds so all sides are evenly coated.
  4. Heat neutral oil in a heavy hob pan over high heat until just smoking.
  5. Sear tuna for 45 to 60 seconds per side for rare (or 90 seconds for medium-rare), keeping the centre pink.
  6. Rest for 1 minute, then slice and serve with spring onions and any extra lime.

Ingredients

  • Black Pepper, to taste
  • 2 tbsp Soy Sauce
  • 1 Garlic Clove grated
  • 2 Spring onions finely sliced, to serve
  • 1 tbsp Neutral Oil for searing
  • 1 tsp Fresh Ginger finely grated
  • 2 tbsp black sesame seeds
  • 2 tbsp White Sesame Seeds
  • 4 x 150 g tuna steaks sashimi-grade if possible
  • Salt, to taste
  • 1 tbsp Lime juice
  • 1 tsp Sesame Oil

Notes

Use very fresh tuna and avoid overcooking to keep the centre silky.
A scorching-hot pan is key for a crisp sesame crust without drying the fish.
If preferred, skip marinating and just brush the tuna lightly before searing.
