Skrei with Tomato and Basil Sauce

40 min
2 portions

February and March are peak season for fresh skrei — here it gets the southern European treatment with cherry tomatoes, garlic, and basil. Ready in 40 minutes and genuinely delicious.

Instructions

  1. 1

    Halve the cherry tomatoes and finely chop the garlic.

  2. 2

    Heat a frying pan with olive oil, add the tomatoes and garlic, then turn the heat down and let them simmer gently in the oil for about 10 minutes until soft.

  3. 3

    Pour in the fish stock and bring it to a boil.

  4. 4

    Chop the basil and stir it into the tomatoes along with the chili flakes, lemon juice, and lemon zest. Season with sugar, salt, and pepper.

  5. 5

    Cut the skrei fillet into four equal pieces and season both sides with salt and pepper.

  6. 6

    Fry the fish pieces in a pan with olive oil until nicely browned on one side. Now add the tomato sauce and let everything simmer together for 3 minutes until the fish is cooked through.

Tips from the kitchen

  • Skrei is leaner than regular cod and overcooks fast. Brown it on one side, then let it finish in the sauce for those 3 minutes and pull it off the heat the moment it flakes apart easily.
  • Keep the tomatoes on low when they simmer in the oil. You want them collapsing into a soft sauce, not frying hard and going bitter around the edges.
  • Add the basil and lemon zest at the end, off the heat or just before the fish goes in. Cook them too long and you lose the fresh sharpness that cuts through the fish.
  • Pat the skrei dry with paper towel before you season and fry it. Wet fish steams instead of browning, and you want a bit of color on that one side.
  • The teaspoon of sugar is there to balance the acidity from the tomatoes and lemon. Taste before you add it, since some cherry tomatoes are sweet enough already.

Ways to vary it

  • If you have capers or a few chopped olives around, stir a spoonful into the sauce for a saltier, more southern Italian feel.
  • A handful of baby spinach wilted into the tomatoes just before the fish goes in works nicely if you want more greens on the plate.
  • Swap the basil for fresh oregano or a mix of both if that's what you have. Oregano gives it a slightly more rustic edge.

Storage & leftovers

Best eaten the day you make it, since the skrei dries out on reheating. Leftovers keep in the fridge for up to two days in a sealed container. Warm gently in a pan with a splash of water or stock over low heat, just until heated through. I wouldn't freeze it, the fish goes mealy.

What to serve with it

Crusty bread to mop up the sauce is all you need, though boiled new potatoes or a simple green salad work too.
