Ingredients
  

  • Main
  • 4 tuna steaks 6 oz / 170 g each, about 1-inch thick
  • 2 tbsp 30 ml olive oil (or avocado oil)
  • Salt and black pepper to taste
  • Marinade
  • 2 tbsp 30 ml fresh lemon juice
  • 2 cloves garlic minced (or 1 tsp garlic powder)
  • 1 tsp 5 g dried oregano or 1 tbsp fresh oregano, chopped
  • 1 tsp 5 g paprika (optional, for color and smokiness)
  • 1 tbsp 15 ml soy sauce or tamari
  • Garnish & Sauce
  • 2 tbsp 8 g fresh parsley, chopped
  • 1 tbsp 15 ml extra virgin olive oil
  • Lemon wedges for serving
  • Optional Add-Ins
  • 1 tsp chili flakes for spice
  • 1 tsp capers or lemon zest for tangy flavor

Method
 

  1. Follow this step-by-step guide to achieve perfectly grilled tuna steaks.
  2. Preparing the Tuna
  3. Pat Tuna Dry
  4. Use a paper towel to pat the tuna steaks dry.
  5. This ensures even searing and prevents sticking.
  6. Season the Tuna
  7. Brush both sides with olive oil, sprinkle salt and pepper evenly.
  8. Let it rest 5 minutes at room temperature for better flavor absorption.
  9. Making the Marinade
  10. Combine Ingredients
  11. In a bowl, whisk together lemon juice, garlic, oregano, paprika, and soy sauce.
  12. Ensure the mixture is smooth and aromatic.
  13. Marinate the Tuna
  14. Place tuna steaks in a shallow dish and pour marinade over them.
  15. Cover and refrigerate for 15-30 minutes.
  16. Pro Tip: Avoid marinating more than 30 minutes to prevent the acid from breaking down the tuna.
  17. Grilling the Tuna
  18. Preheat the Grill or Pan
  19. Preheat a grill pan or outdoor grill to 220°C / 425°F.
  20. Brush lightly with oil to prevent sticking.
  21. Grill the Tuna
  22. Place steaks on the hot grill. Grill 2-3 minutes per side for medium-rare (visual cue: grill marks appear, edges firm but center still pink).
  23. Use tongs to gently flip without pressing.
  24. Check Doneness
  25. Tuna should be firm on the outside but slightly translucent in the center.
  26. Optional: use a thermometer, medium-rare = 50°C / 122°F internal temperature.
  27. Rest the Tuna
  28. Remove from grill and let rest 3 minutes.
  29. This locks in juices and enhances flavor.
  30. Tips and Tricks for Perfect Tuna
  31. Slice Against the Grain
  32. For best texture, slice tuna steaks against the grain when serving.
  33. Add Garnish & Serve
  34. Drizzle extra virgin olive oil and sprinkle fresh parsley on top.
  35. Serve with lemon wedges and your favorite Mediterranean sides.
  36. Troubleshooting
  37. Overcooked tuna: Grill faster at high heat and avoid leaving on the grill too long.
  38. Sticky tuna: Pat dry and lightly oil the grill or pan.
  39. Storage and Reheating
  40. Fridge: Store grilled tuna in an airtight container for up to 2 days.
  41. Reheat: Warm gently at 150°C / 300°F for 5-7 minutes or serve cold in salads.
