Tuna Steak with Tomato, Caper and Lemon Dressing

There’s a lot to love about a Tuna Steak – even if you’re not a fan of seafood. Even though the flavour can be subtle its oily nature gives it more punch than other fish. Its texture is firm and meaty – even though it flakes it doesn’t fall apart easily. Plus it’s quick to cook, needing little more than 2 minutes per side on a hot griddle. If you’re after a tasty, quick meal then look no further.

I have to admit that I was slightly surpised when, after serving this, Michael commented that he probably preferred tuna steak to beef steak. Though thinking it over he does have a point. I’ve had proportionally more disappointing sirloin or ribeye steaks than I have of tuna (or swordfish). The chances of having to chew your way through a tuna steak are, in my experience, a lot lower.

Much like a beef steak you could serve tuna straight from the pan, with its juices, and it would be a nice meal. Though in the same vein it also lends itself to a well-flavoured sauce. In the past I have served tuna with roasted mediterranean vegetables and a herb dressing. Or alongside a more asian-inspired ginger and garlic sauce.

In this case I wanted something light yet punchy, so chose a warm vinaigrette made with fresh tomatoes, capers, shallot and lemon, alongside olive oil and vinegar. When warmed in a pan the flavours really come together and make a wonderful partner for the fish. The zesty lemon and sharp capers contrasting perfectly with the rich, oily tuna. Perfection.

For the Vinaigrette

  • 1 Shallot peeled and finely chopped
  • 1 clove Garlic peeled and finely chopped
  • 1 Tomato peeled, deseeded and chopped
  • 1 heaped tsp Capers rinsed
  • 1 Lemon juice plus 1 tsp lemon zest
  • 1 tsp Fresh Coriander finely chopped
  • 1 tsp Cider Vinegar
  • 2 tbsp Extra Virgin Olive Oil
  • Pinch Sea Salt Flakes
  • Pinch Freshly Ground Black Pepper

For the Tuna

  • 2 tbsp Olive Oil
  • 2 Tuna Steaks


  • To prepare the dressing, mix all of the ingredients together in a bowl and season to taste. Put to one side until needed.
  • Brush a heavy frying pan or griddle with a little oil, then put over a medium-high heat for a few minutes until smoking hot.
  • Meanwhile brush the tuna steaks with the remaining oil. Carefully lower into the pan then cook for 2 minutes on each side, turning carefully when needed. This should leave the tuna slightly pink in the middle, so if you like it cooked through increase the cooking time slightly.
  • Whilst the tuna is cooking put the dressing into a small pan and heat until warmed through. You don’t want it to cook, but a little heat will allow the flavours to develop.
  • Serve the tuna with a couple of tablespoons of the dressing drizzled over the top. Put the remaining dressing into a small bowl and serve alongside.
