Grilled Tuna Steaks

Perfectly Seared, Simply Delicious
Home / Recipe / Grilled Tuna Steaks

Tuna steaks are meaty, satisfying, and cook faster than most takeaways. Rich in omega-3 fatty acids and complete protein, they support heart health, brain function, and muscle recovery. A simple marinade and hot pan are all you need.

Serves: 2  |
 Cook Time: 11 minutes (plus 15 minutes marinating)
Ingredients
  • 2 fresh tuna steaks (about 180-200g each, 2-3cm thick)
  • 2 tablespoons extra virgin olive oil
  • Zest and juice of 1 lemon
  • 2 garlic cloves, minced
  • 1 teaspoon Dijon mustard (optional)
  • Fresh cracked black pepper
  • Sea salt flakes
  • Fresh herbs (dill, parsley, or basil) for serving
  • Lemon wedges for serving

Directions

  • In a shallow dish, whisk together olive oil, lemon zest, lemon juice, minced garlic, and Dijon mustard (if using). Season with black pepper.
  • Pat the tuna steaks dry with kitchen paper. Place them in the marinade, turning to coat both sides. Cover and refrigerate for 15-30 minutes.
  • Remove the tuna from the fridge 10 minutes before cooking.
  • Heat a griddle pan, barbecue, or heavy-based frying pan over high heat until smoking hot.
  • Remove tuna from marinade, pat dry, and brush lightly with olive oil. Season with sea salt flakes just before cooking.
  • Place the tuna steaks on the hot grill/pan. Do not move them. Cook for 1½-2 minutes on the first side without touching.
  • Flip the steaks and cook for another 1½-2 minutes for rare to medium-rare (the centre should still be pink/red). For medium, cook 3 minutes per side. For well-done, cook 4 minutes per side.
  • Transfer to a plate and let rest for 2 minutes.
  • Slice against the grain into thick slices. Drizzle with fresh lemon juice, scatter with fresh herbs, and serve with lemon wedges.
