Seared tuna steaks, pink in the middle, with a fresh avocado, tomato and lime salsa. Four servings in 21 minutes.
Make Ahead and Storage
Best eaten straight away. Leftover seared tuna keeps in the fridge for up to 2 days; eat it cold, flaked into a salad. The salsa is best fresh, since avocado browns.

-
Make the salsa: toss the avocado, tomatoes, red onion, jalapeño, cilantro, lime juice and the ¼ tsp salt in a bowl. Set aside.
-
Pat the tuna dry. Rub it with the oil and season with the paprika, the ½ tsp salt and the pepper.
-
Heat a heavy frying pan or griddle over high heat until very hot. Sear the tuna for 2 to 3 minutes on each side, until browned outside and still pink in the centre.
-
Rest for 2 minutes, slice across the grain and serve with the salsa alongside.
Worth Knowing
- Add a minute a side if you prefer the tuna cooked through, but expect a drier steak.
- Choose avocados that give slightly when pressed; a hard one makes a bland, crunchy salsa.
- Heat the pan until a drop of water skitters across it before the fish goes in.
Behind the Recipe
The usual way tuna steaks go wrong is overcooking: a steak cooked right through turns dry and mealy, a little like canned tuna. Tuna is lean, so there is little fat to protect it. Hot pan, short time. Sear for 2 to 3 minutes a side, so the outside is browned and the middle is still pink.
The salsa is the cool contrast. Dice the avocado last, so it stays green, and stir in the lime juice at once. A ripe avocado gives slightly when pressed. Dry the tuna thoroughly before it hits the pan, since moisture means steam, not a seared crust. Season just before cooking, not ahead, because salt draws water out of the surface.
Buy tuna from a fishmonger you trust and ask for fish that is suitable to eat rare. Slice across the grain to serve. Spoon the salsa alongside rather than over the top, so the crust stays crisp. Leftover tuna flakes well into a green salad for lunch.
