Fresh or Frozen Tuna Steak
Fresh fish is always preferred for any recipes but unfortunately it is not always ready available, especially if you don't live near the ocean.
- Fresh Tuna: Fresh tuna is delicious and will keep a great texture. Make sure that the steak it's at least 2 cm (¾ inch) thick to get the best result.
- Frozen Tuna: Frozen tuna steaks are a good alternative if you cannot find fresh fish in your supermarket. Make sure you thaw them first before cooking. Better if thawed overnight in the fridge.

Variations
- Asian fusion - Add sesame seeds and a splash of soy sauce to the crust for an umami twist. Serve with a sesame cucumber salad on the side.
- Spicy version - Add a pinch of chili flakes or Aleppo pepper to the crust mix for a gentle kick.
- Herbed crust - Mix in chopped fresh herbs like parsley, basil, or thyme with the crust for extra fragrance and color.
- Baked version - Instead of pan-searing, bake the crusted tuna at 200°C/400°F for about 10-12 minutes for a slightly more well-done result.
Storage & Reheating
Fridge: Store leftover cooked tuna in an airtight container for up to 2 days. Best enjoyed cold or at room temperature-like in salads or grain bowls.
Reheating: Not recommended, as tuna dries out easily when reheated. If needed, reheat gently in a covered pan with a splash of water or broth just until warmed through.
Freezer: This dish is best enjoyed fresh; freezing cooked tuna is not ideal due to texture changes.

📖 RECIPE
Ingredients
Method
- Rub the tuna steaks in extra-virgin olive oil and set them aside. Finely chop the sun-dried tomatoes and the pistachios and mix them together in a small bowl.
- Add the poppy seeds and the breadcrumbs to the bowl and season well with salt and pepper.
- Transfer the mix into a small plate and press the tuna steaks until well coated. If the crust mixture does not adhere properly to the tuna, it means it's either not chopped finely enough or the steaks are too dry.
- Drizzle some olive oil in a pan and when hot add the tuna steaks. Sear for about 1 minute on each side and serve immediately.
