In Algeria, Friday is not a day like any other. It is the smell of the broth that has been simmering since morning, the steam of the semolina rising from the couscoussier, the children circling around the kitchen, and the whole family sitting down together around 1 pm. This ritual is not something you replace. It is not something you negotiate. When you are a dialysis patient, the temptation might be to fade away from the family table, to eat "your own separate dish", to turn Friday into a day of deprivation. That would be a mistake — for morale, for family bonds, and even for adherence over the long term.
Our stance is clear: there is no question of giving up the Friday couscous. When you are on haemodialysis, you learn to work around a few nutritional constraints, but the pleasure of eating with your family remains a cornerstone of quality of life. The good news is that Algerian couscous, well thought through, can absolutely fit into a diet adapted to dialysis. The semolina itself is an ally. It is mainly the side elements that call for a little attention: the salt, certain vegetables, certain meats, and the volume of broth served.
In this article, we look concretely at how to keep the ritual intact, without spoiling your test results. No "sad light version", no miracle substitute. Just the right habits, the right proportions, and a few adjustments that whoever cooks for you will quickly take on board — often without anyone around the table noticing the difference.
Why "classic" couscous can cause trouble
Couscous as it is traditionally prepared is not dangerous in itself. It simply combines several elements which, when added together, can push up certain parameters monitored in dialysis. Four main pitfalls to be aware of.
Salt. This is often the first culprit. Broth salted by the ladleful during cooking, smen added at the end of preparation, sometimes a shop-bought stock cube to "lift" the flavour, white bread dipped in the sauce, harissa spread on top. Added together, the total is heavy — especially for someone who has to limit their sodium load and fluid volume between two sessions.
Potassium. K+ is concentrated in several staple ingredients of couscous: potato, tomato purée (very concentrated, precisely), chickpeas, certain green herbs in large quantities, and certain vegetables depending on the portion. For someone whose kidneys no longer filter potassium, this build-up can pose a real cardiac problem.
Phosphorus. It is present in red meat, offal (liver, heart, tongue, which people like to add on a Friday), pulses such as chickpeas, and certain cheeses sometimes set out on the table. Phosphorus, poorly managed over the long term in chronic kidney disease, weakens the bones and the blood vessels.
Fluid volume. The broth is delicious. But a large ladle easily amounts to 200 to 300 ml of liquid. For a dialysis patient who has a restricted fluid intake instruction, two ladles can already harm the interdialytic weight-gain balance.
The semolina: your ally, in sensible moderation
First piece of good news, and it matters: durum wheat semolina is rather your friend. It is relatively low in potassium and phosphorus, it is an excellent source of energy, and it fills you up well. For a dialysis patient who often needs an adequate calorie intake (undernutrition is a real risk in dialysis), semolina plays a useful role.
Go for a generous portion of semolina on your plate. Traditional steam cooking, in two or three passes in the couscoussier, just as it has always been done. Butter or olive oil in a reasonable quantity to "roll" it well: no problem there — we are even looking for a little fat for the calories. It is the base of your Friday plate. The rest comes to sit on top in a more measured quantity.
The broth: where the salt hides
This is probably the point that calls for the most vigilance, and the one that changes the dish the most. The watchword: we add flavour, we do not add salt.
- No shop-bought stock cube. A single cube can represent the equivalent of 1.5 to 2 g of salt. There is no point going without it in everyday life only to salt it heavily on a Friday.
- No smen added at the end of cooking. Traditional smen brings salt and saturated fat. If you are attached to its aroma, a tiny touch at the start of cooking is enough, but not a full spoonful at serving time.
- We add flavour another way, and powerfully. Fresh coriander, parsley, gently softened onion, garlic, turmeric, ras-el-hanout (measured out), a little cumin, a hint of ginger. The broth has plenty of taste — it is not the salt that carries it, it is the spices and herbs.
- We serve a half-ladle, not a large ladle. This simple gesture limits the fluid dose without frustrating anyone: the semolina is already flavoured, and the plate remains a treat.
This work on the broth is a little like during Ramadan: adapting traditional dishes is quite an art, and it is quickly passed on to whoever does the cooking.
The vegetables: the good ones, the "double-cook" ones, the "limit" ones
Not all vegetables are equal in an adapted plate of couscous. Here is a handy mental map.
The good ones (in a moderate portion): courgette, carrot, turnip, butternut squash (yes, contrary to a common belief, it remains edible in a reasonable portion), cauliflower (preferably rinsed in water after cooking). These vegetables, in normal plate quantities, rarely cause trouble.
The potato case — the technique that changes everything. Potato is not forbidden, it just calls for a double cooking that significantly lowers its potassium:
- Peel and cut into small cubes.
- Soak them for 2 to 3 hours in plenty of water (this water is thrown away).
- Then cook them in a large amount of water that is also thrown away before adding them to the dish (or serving them).
This step, which we can call "worked potato", removes a good part of the initial K+. It is the habit to pass on to the person who cooks for you.
To limit:
- Chickpeas are rich in potassium and phosphorus (even more so before soaking). Rather than a big handful, we put a small amount "for the look" on the plate, and that is all — always after a long soak and cooking in water that is thrown away.
- Tomato purée is very concentrated in K+ (that is the logic of a concentrate). Prefer a single teaspoon in the broth, and instead add a small piece of fresh tomato for the colour.
The meat: what we choose on a Friday
The Friday couscous can perfectly well stay meat-based, you simply choose with care.
- Red meat (mutton, lamb): it remains possible, but in a limited portion, well trimmed of fat, and favouring a lean cut. Mutton fat brings phosphorus and saturated calories that you do not need in large quantities.
- White meat (chicken): an excellent alternative every other Friday. Less phosphorus, easier to digest, lighter on the kidneys and the overall balance.
- Offal (heart, liver, tongue, tripe): much enjoyed in Algeria, but very rich in phosphorus and potassium. For a dialysis patient, we keep them occasional and in a small portion.
- Merguez: very salty and fatty. To be limited firmly, not every Friday.
The portion: the real gesture that changes everything
This is undoubtedly the most important rule of all, and the simplest to apply: the plate is served by the cook, not self-service. Couscous from a shared communal dish where everyone helps themselves can lead, without anyone realising it, to double portions of chickpeas, broth and meat.
Picture the ideal plate of a dialysis patient on a Friday:
- 50% semolina (the base, generous)
- 25% mixed vegetables (courgette, carrot, turnip, a little squash, worked potato)
- 15% meat (chicken or trimmed mutton)
- 10% "decorative" chickpeas (a small handful, no more)
- A half-ladle of broth (flavoured, lightly salted)
This distribution lets you enjoy everything without excess on any one pillar. No one feels punished at the table, and your parameters do not shoot up.
The accompaniments: harissa, lben, lemon
The rituals that surround couscous count as much as the dish itself. We can keep them, in an adapted dose.
- Harissa: a small touch is perfectly fine (little salt on a small quantity, lots of taste). We simply avoid spreading a big spoonful.
- Lben (buttermilk): it is the traditional companion, but it is rich in phosphorus and potassium. Prefer a small glass occasionally rather than a jug shared throughout the meal.
- Water or a light herbal tea as the main drink, rather than fizzy or sugary drinks that bring nothing and push up interdialytic weight gain.
- Lemon squeezed over the plate: no problem at all, and it lifts the flavours without salt.
The Friday desserts: kalb el louz, makroud, baklava
On a Friday, the table often carries on with a tea and a sweet treat. We do not cut it out, we portion it.
Rather than going through three small servings of different pastries, choose half a portion of a single dessert that you truly love — a kalb el louz, a makroud, a piece of baklava. The pleasure is complete, while the load of sugar, phosphorus and calories stays reasonable.
Another perfectly respectable option every other Friday: a fresh fruit such as an apple or a pear, which are among the best-tolerated fruits in dialysis in a moderate quantity. Citrus fruits in a small quantity may also be suitable depending on your test results.

Adjust the quantities according to your dietary prescription and your personal tolerance.
At the ESSAADA Clinic, we work with you
Every patient on a haemodialysis pathway has their own targets: your dry weight, your blood test results, your residual renal function, your comorbidities, your age, your level of physical activity — all of this shapes what you can allow yourself. During your nephrology consultation, your doctor sets these markers with you, and dietary follow-up can be arranged according to your needs.
To better understand the background to all these dietary adaptations, you can read our feature Understanding kidney failure again. Keeping the pleasure of food, eating with your family, enjoying the Friday couscous: this is not a luxury, it is an essential part of "living well" with long-term dialysis. A patient who keeps sharing family rituals is a patient who follows their treatment better, and who is generally doing better.
Any other questions about food, drinks, sweet treats, the daily bread? Our FAQ brings together concrete answers to questions that our dialysis patients and their families in Sidi Bel Abbès often ask us. Do feel free to consult it, and to discuss each adaptation with your nephrologist.
This recipe is a basis for adaptation, not a prescription. Your tolerated amounts of salt, potassium, phosphorus and fluid are set by your nephrologist according to your test results. Adjust them in line with their recommendations.
