Method

  • step 1

    Heat oven to 180C/160C fan/gas 4. Toss the bread with 1 tsp oil, season, then scatter over a baking sheet. Bake for 10-12 mins or until crisped and golden.

  • step 2

    Rub 1 tsp oil, half the lemon zest, some salt and plenty of black pepper over the tuna steaks. Set aside.

  • step 3

    Gently heat the remaining oil in a non-stick frying pan. Add the anchovies and garlic, and cook for 1 min, mashing the anchovy to create a purée. Scrape into a into a large bowl, then stir in the mayo, buttermilk, mustard, Worcestershire sauce and parmesan, plus the rest of the lemon zest and 1 tbsp lemon juice to make a loose dressing. Tumble the leaves into the dressing and massage well to make sure they are well coated. Leave for 5 mins so that the dressing begins to soften the cavolo nero.

  • step 4

    Wipe out the frying pan and set over a high heat. Sear the tuna for 2-3 mins each side until just pink in the middle, or longer if you prefer. Let it rest on a plate for 1-2 mins. Pile the dressed cavolo nero onto plates, top with the fish, then scatter with the shaved parmesan and croutons. Drizzle with a little more extra virgin olive oil, if you like, then serve with the rest of the lemon, cut into wedges.

Just tried this and it was a great success. I used a tbsp of yogurt and splash of milk since I didn’t have the buttermilk.

Really good recipe. I prefer a more robust dressing so it was two anchovies and two cloves per steak.

Used cream as no buttermilk and kale works as well. I blanched it before adding which had the benefit of loosening the sauce. New firm favourite!

Didn’t bother with the croutons and used romaine lettuce roughly torn, instead of the cavolo nero, as that is what I had. Absolutely delish!

Half the Lemon Zest

andrewJSY

Great dish! But a little too much lemon zest, can over power, would suggest half the lemon.
