A roast dinner that’s low in potassium, phosphate, and salt. It's also high in protein so makes a great hearty post-dialysis meal.


1 medium chicken, approx 1.5-1.7kg (100g of cooked chicken per person)

1 small onion, roughly chopped

1 lemon, halved

Cracked black pepper

1 teaspoon dried sage

4 medium potatoes (approx. 500g) peeled and cut into four

2 tablespoons olive oil

1 sprig rosemary

250g swede, peeled and chopped into chunks

40g unsalted butter

250g spring greens, shredded, or carrots, peeled and chopped

250ml low-salt chicken stock

15g plain flour


  1. Step 1

    Heat the oven to 180°C/ 160°C fan/ gas mark 4. Put the chopped onion into the bottom of a roasting tray. Stuff the lemon halves into the cavity of the chicken and sit the chicken on top of the onions. Season the chicken with black pepper and the dried sage, then rub into the skin. Roast the chicken in the oven for 1 hour and 20 minutes.

  2. Step 2

    Put the potatoes into a pan of cold water and bring it to the boil. Cook until the potatoes are soft, then drain in a colander. Shake the potatoes to rough the edges up a little. Cover with a tea towel to trap any remaining steam.

  3. Step 3

    Heat another roasting tin with olive oil in the oven for 5 minutes, then remove and add the par-boiled potatoes, turning them to coat in oil. Add the rosemary and return to the oven for 45 minutes.

  4. Step 4

    Add the swede to a saucepan of cold water and boil until soft, then drain and return the swede to the pan. Add the unsalted butter and black pepper to taste and mash, then keep warm until serving. 10 minutes before serving, add the shredded spring greens or chopped carrots to a saucepan of water and boil until cooked. Once cooked through, drain and discard the water.

  5. Step 5

    Take the chicken out of the oven, remove from the roasting tin and allow any juices to drain back into the tray. Set the chicken to one side and allow to rest for 15 minutes. Put the roasting tin over a low heat on the hob and stir in the flour. Cook until the juices have absorbed. Add the stock slowly, stirring until the gravy thickens. Strain and set aside.

  6. Step 6

    Remove the potatoes from the oven. Serve the chicken, potatoes and vegetables on warm plates and pour the gravy over the top
