Beetroot & Lemon Zest Home Cured Trout

I planned to make beetroot and lemon cured salmon for Christmas day.

I planned a great many trootI planned to have a practice run a month or two in advance, trying out two different cures and choosing the one which worked best. No trial run happened. I planned to ask for more advice on recipe variations from expert friends. In the end I turned to recipes found on the internet and had a mild panic about which one to follow. I planned to order one enormous and gorgeous wild salmon fillet in advance. I failed to do so and went with what I could find in Waitrose at the last minute. But the wild Alaskan salmon they’d stocked a few weeks previously was nowhere to be seen, and the farmed salmon looked particularly insipid.

And that’s how I ended up buying two Loch Melfort trout fillets instead. The trout simply looked far more appealing and I decided, with no knowledge to back it up whatsoever, that it would work just as well as salmon for my purposes!

Having found a great many recipes for beetroot cured salmon online, I narrowed my choices down to Nigel, Jamie and Barney (from BBC Good Food).

All three offer fairly similar recipes and techniques featuring the salmon itself, salt, sugar and raw beetroot. Jamie and Nigel add citrus zest and vodka to theirs. Jamie and Barney include a little horseradish too. What varies most in their recipes are the proportions of beetroot, salt and sugar to salmon and how long to apply the cure. Jamie and Nigel both have almost the same salt to salmon ratio, but Nigel calls for more sugar and much more beetroot. Barney’s recipe calls for more sugar than salt and far less of everything against the salmon. Jamie recommends curing the fish for 48 hours, Nigel suggests 2 to 4 days and Barney stretches from 3 days up to a week.

I dithered between the three recipes for a frankly ridiculous number of hours before basing my ratios on the box size of salt I’d purchased, and what my trout and beetroot weighed!

I needn’t have worried so much. The finished trout was both beautiful and delicious. The purple-red and orange colours made it very festive for our Christmas day table but would also make this a lovely recipe to prepare for Valentine’s day.

Beetroot & Lemon Zest Home Cured Trout (or Salmon)


  • 1.5 kg boned fillets of trout or salmon , skin on
  • 350 g coarse crystal sea salt
  • 200 g demerara sugar
  • 900 g raw beetroot
  • 2 lemons , zested


Scale the recipe up or down depending on the weight of your fish.


  • Grate the raw beetroot; no need to remove the skin first. I used a food processor which seemed to release a lot of juice. If the beetroot is very wet, drain using a sieve, to remove excess liquid.
  • Weigh the sugar and salt, and add the grated lemon zest. Combine with the grated beetroot and mix well.
  • In a large dish, lay out a piece of cling film and spread a thin layer of the curing mix over it. Lay the fish, skin side down, on the cling film.
  • Put a much thicker layer of the curing mix over the flesh side of the fillet, making sure all the flesh is covered. As I had two equally sized fillets, I laid the second one flesh side down over the first, and then added a last thin layer of curing mix over the skin of the second fillet. If you only have one fillet, divide your curing mix accordingly, using the majority on the flesh side of the fish.
  • Wrap the cling film around the fish and add two or three further layers of cling film to ensure that the fish is securely wrapped.
  • Weigh down the fish with a flat tray and something heavy on top and place in the fridge.
  • Once a day, check the fish and pour away any liquid that has collected in the dish. You don’t need to unwrap the cling film – the liquid seems to find its way out. After draining, turn the fish over, replace the weights, and return to the fridge.
  • I allowed my fish to cure for 4 days. Based on Nigel, Jamie and Barney’s recipes for salmon, I’d imagine that a period of anywhere between 2 to 7 days would work.
  • Once wiped clean, the final purple-red colouring of the cured trout will be revealed. Mine had a somewhat mottled effect where more or less colour from the beetroot had stained the flesh.
  • Slice the fish just before serving. I did my best to cut reasonably thin and even slices, slicing the knife downwards at an angle and then along the skin.

The beautiful purple-red staining had penetrated reasonably well into the flesh, and looked glorious against the bright orange.

The trout was simply served with lemon wedges, sour cream and undressed rocket leaves.


The second fillet, which was wiped clean at the same time of the first, then re-wrapped in cling film and left in the fridge for another day and a half, seemed to be even darker than the first, though they had both cured for the same length of time. Once back home, I removed the flesh from the skin in four pieces which were individually wrapped and frozen.

I have wanted to cure my own fish for the longest time, but was always put off by worries of getting it wrong and ruining perfectly good fish. I’m glad that everyone I talked to about it encouraged me to have a go as it was very worthwhile and definitely rewarding. It was also far easier than I imagined!

Do have a go and let me know how you get on!

    Oh great! Been looking for another thing to do with trout. Our cleaner at work loves to fish for them but hates eating them so gives them to us! We have LOADS in the freezer. Thanks x


    Lucky you! I’ve been told that trout doesn’t need as long to cure as salmon, though mine was fine, but you may find that the 7 days in Barney’s salmon recipe is too long for trout. Let me know how you get on!

    Oh this is enchantingly pretty. I have to say that pink and orange is one of my favourite colour combinations – it screams happiness in my mind! I knew about beetroot cures, but I think the addition of lemon has won it for me. Gorgeous!

    BTW, Nigel, Jamie and Barnie sounds like an idea for a kids’ tv programme!

    Eeek no, am not a fan of dill. Can eat it in small quantities but dill pickles and dill cures are my very least favourite.
