  • sunflower oil
  • sausages 8 (apple, sage and mustard flavours all work well)
  • potatoes 3, large
  • thyme 3 sprigs, leaves stripped
  • grainy mustard 2 tbsp
  • English mustard powder 2 tsp
  • egg 1, beaten


  • onions 2, thinly sliced
  • butter 25g
  • brown sugar 1 tbsp, any kind
  • plain flour 2 tbsp
  • chicken or vegetable stock 500ml
  • Worcestershire sauce 1 tbsp


  • Step 1

    Heat the oven to 180C/fan 160C/gas 4. Brush 1 tbsp oil over a shallow roasting tin, about a4-sized, or a round ovenproof pan, about 20-22cm across.

  • Step 2

    Brown the sausages in 1 tsp oil for 5 minutes or until golden. Grate the potatoes (no need to peel them), put into a clean tea towel and squeeze out as much water as you can. Tip into a bowl and mix in the thyme, half the grainy mustard, all the mustard powder, the egg and ½ tsp salt plus some black pepper. Tip into the roasting tin and add the sausages. Brush a little oil over the potato and bake for 45-50 minutes until the sausages and potato are crisp, golden and cooked through.

  • Step 3

    While the sausage röstis are baking, make the gravy. Put the onions and butter in a frying pan and cook gently until really soft and starting to caramelise – about 20-30 minutes. stir in the sugar, and brown over a higher heat for a couple of minutes, then stir in the flour, mixing until it has blended in. Gradually stir in the stock, followed by the remaining 1 tbsp grainy mustard and worcestershire sauce. Bring to a simmer and bubble, then reduce until it has a good consistency. Season to taste. Scoop the sausage röstis straight from the tin and serve with green veg and plenty of gravy.
