Tuna steak for dinner? Yes please!

Who doesn’t love a nice tuna steak? Well, if you had asked me about 10 years ago, I would have probably raised my hand (weird, eh?). Growing up in Romania, fresh fish was a rare treat for us during my childhood, and for many years all I ever knew about tuna was that it comes in a can. And that it is rather bland. But things have changed when I moved to London and found here what I call ‘the fish heaven’. Or what is more commonly known as Billingsgate Fish Market.

If you follow me on Instagram, you probably know that cooking fish is my new obsession. And how could it not be – with so many varieties of fish available here. ¬†Over time I’ve been pretty much experimenting with every fish that I found in supermarkets. On my first night trip to Billingsgate fish market – the place where most London restaurants source their fish from – was when I first bought fresh tuna. I can still remember that excitement when I got home and cooked it.

Grilled tuna steak by chef Adam Gray at the Great British Chefs Cook School

Besides cooking my own dishes, there’s nothing I love more other than watching great chefs cook and learning from them. I have always believed that as a chef there is no such thing as ‘I know it all’. There’s always something new to learn form other chefs but also from people around us.

The Great British Chefs Cook School is a great opportunity to learn from some of the greatest chefs in Britain. At last week’s event I met Adam Gray – the executive chef of Skylon Restaurant in London. I absolutely loved his passion for healthy food and his no-nonsense approach to cooking good food. The cooking lesson was all about respecting the ingredients and making an exquisite dinner that not only looks good on a plate, but it is healthy and above all, full of flavour.

The dish demonstrated by Adam was grilled tuna steak with Asian-style coleslaw. What you need to know about tuna steak, is that it only has to be cooked for a couple of minutes on each side. You need a very hot pan (a griddle pan would be ideal, but a cast iron pan would work just as well) and just some seasoning on the fish (salt, pepper and a bit of oil). The garnish – Asian-style coleslaw is a healthier take on the classic coleslaw, as it is not made with mayonnaise, but with an olive oil, lemon and soy sauce dressing. I actually enjoyed it more than the classic coleslaw: the red cabbage was full of flavour and the dressing was light and fresh – perfect for the summer. Some lightly grilled tender stem broccoli will complete the dish, bringing more flavour, a crunchy texture and a bright green colour.
