Mackerel with Roasted Beetroot, Lambs Lettuce, Lentils and Horseradish Dipping Sauce
I managed to source some fresh horseradish from my local farmer’s market. So I relished (excused the pun!) the opportunity to make something with a horseradish flavour without mayonnaise or vinegar in it.
Serves 2
50 mins
4 raw beetroot
1 tbsp olive oil
Salt and Pepper
60g lentils
Sprig of thyme
4-5 parsley stalks
Fresh horseradish (4 tsp when finely grated)
4 tsp chopped parsley
3 tbsp full fat probiotic yoghurt
50g lambs lettuce
1 lemon
2 tsp extra virgin olive oil
4 fresh mackerel fillets (skin left on)
1 tbsp olive oil
Salt and Pepper
- Preheat the oven to 180C
- Chop the leafy tops off the beetroot and scrub away mud under the tap.
- Chop off top and tail and slice away any rough edges. Cut into about 6 wedges per beetroot.
- Place in a baking tray with a drizzle of olive oil. Toss with your hands so all the wedges are covered. Spinkle with salt and pepper. Place in the oven for 35-40 minutes until cooked through turning halfway through.
- Boil the kettle
- Put lentils in with thyme, parsley stalks and half a litre of hot water, bring to the boil and simmer for 25 – 30 minutes until the water is absorbed, the lentils are cooked through but not mushy.
- Grate the horseradish, chop the parsley and add to the yoghurt for your dipping sauce.
- Dress the lambs lettuce with the juice of half the lemon and extra virgin olive oil
- 8 minutes before everything is ready heat up a frying pan on the hob with 1 tbsp of olive oil.
- After 3 minutes turn down to medium and add the mackerel one fillet at a time, skin side down, pushing down with a fish slice so it doesn’t curl up. Once all are added, squeeze over the juice of the other lemon half and sprinkle with salt and pepper. Cook for 3 – 4 minutes until the top is almost all white then flip over and cook the other side for 1 minute.
- Remove all from heat. Arrange the lambs lettuce on plates, sprinkle with lentils, add beetroot and fish. Drizzle over some dipping sauce but put the rest in a little bowl for dipping!
- Delicious and healthy!


Hi, Fab blog! I have just set up mine, but still in the very early stages! Just making efforts to link in with fellow bloggers to improve our followers and get the word out there for us both. Beetroot is a fab product! There is a picky on my first blog of a beetroot dish and just shows what can be done! I would appreciate you having a peek at my blog, as I have just published my first post. Feel free to like, comment, follow or just take a peek. Thank you 🙂
