This twist on bubble and squeak with a poached egg and hollandaise sauce makes a great brunch dish. Leave out the hollandaise if you like, or if you’re not in the mood to poach eggs you can fry them instead. The easiest way to cook lots of poached eggs together is to cook them one by one, carefully transferring them when cooked using a ladle into a bowl of very cold/iced water to stop the cooking, then gently reheat them in hot (not boiling) water before serving. 

Prep time: 10 minutes

Cooking time: 20 minutes

Ingredients (Serves 4)

1 large leek or 1 large or 2 small onions, finely sliced

Butter or oil for frying

400 grams floury potatoes, cooked & mashed (use leftover potatoes if you like)

200 grams brussels sprouts, cooked & thinly sliced, or another green veg of your choice

sea salt and cracked black pepper

4 eggs

White wine vinegar

For the hollandaise

Splash of white wine vinegar

4 egg yolks

1 tablespoon Dijon mustard

250 grams melted unsalted butter

1 lemon


  1. Cook the leek on a low heat in a knob of butter or a splash of oil, stirring now and then to stop it catching, until softened without colouring. Mix with the potatoes and sprouts, season well, then form into 8 balls and gently flatten slightly into small pattie/burger shapes.
  2. Melt a knob of butter in a non-stick frying pan. Fry the cakes until golden & crispy on both sides, in batches if your pan is not big enough. Keep warm in a low oven while you poach the eggs and make the hollandaise.
  3. Bring a large pan of water to a gentle rolling boil (not bubbling). Add a good splash of white wine vinegar and swirl the water with a wooden spoon into a whirlpool.
  4. Crack one egg into a small bowl or ramekin, then tip it into the pan. Cook for 2½ minutes. (See our tip for poaching more than one egg above). Keep the water in the pan hot for reheating the eggs.
  5. To make the hollandaise, put the egg yolks and a splash of white wine vinegar in a heatproof bowl, one that fits snugly over a pan of simmering water (don’t let the bottom of the bowl touch the water). Whisk constantly over a gentle heat until voluminous. Gradually pour in the melted butter, whisking constantly, until you have a smooth, glossy sauce (you may not need quite all of the butter).
  6. Stir in the mustard, a squeeze of lemon juice and salt to taste.
  7. Reheat the eggs in the hot water, then serve 2 cakes each with a poached egg and drizzle over some of the hollandaise.

Food savvy tip. Eggs have a best before date, after which they are likely still fine to eat. You’ll know if your egg is not safe to eat if it releases an unpleasant odour when cracked. 

Want to know if your egg is still fresh? Float it in a bowl of water. The least fresh will float to the top whilst newer eggs will sink.
