How to cook tuna steak

Tuna is best served slightly pink in the middle, so take care not to overcook it.

Pan fry

Heat a little oil in a frying pan over a high heat. Season the tuna steak and cook for 2 minutes per side. Rest for a few minutes before serving.

Bake

For a more hands-off approach, place tuna steaks in a lightly oiled baking dish and season as desired. Bake in a preheated oven at 200°C/180°C fan/gas mark 6 for 12-15 minutes, depending on thickness and how well cooked you like it.

Barbecue

Brush the tuna steaks with oil and cook over a hot barbecue for 2-3 minutes per side. The high heat creates a delicious char while keeping the centre tender and succulent.

Griddle

A hot griddle pan gives tuna steak attractive chargrill marks and plenty of flavour. Cook for 2-3 minutes per side.

How to prep a tuna steak

With its firm texture and delicate flavour, this versatile fish needs very little preparation to shine. If you're using frozen tuna, defrost it thoroughly in the fridge before cooking. Pat the steaks dry with kitchen paper, then season lightly with salt and pepper just before they hit the heat to help create a beautifully caramelised crust. Tuna also takes well to bold marinades. Try an Asian-inspired mix of soy sauce, toasted sesame oil and a touch of honey, but marinate for no longer than 15 minutes, as the delicate flesh can start to change texture.

What to serve with tuna steak

Tuna steak is the perfect starting point for everything from light lunches to flavour-packed dinners. Try it in a classic tuna niçoise with green beans, olives and soft-boiled eggs, serve it with caponata and butter beans for a Mediterranean-inspired supper, or slice it over sticky rice with avocado and smacked cucumber for a fresh poke bowl. It's also an easy alternative to steak, salmon or chicken in many favourite recipes, from noodle stir-fries and tacos to loaded flatbreads and grain bowls.
