Potato rosti with sour cream and caviar

Rosti usually involve both grating and frying – both of which can seem like a step too far, I know. And honestly, boiled new potatoes cut in half lengthwise and smothered with sour cream and caviar are a delicious alternative. But I’m looking for crunch, so I persevere.

And while I can’t think of a short cut for the grating – though a food-processor will do the job, providing the grater attachment can be located, by which time it would usually have been quicker for me just to grate the potato in the first place – but the frying? Totally.

I bake my rosti in a thin layer in the bottom of muffin tins. This has the added bonus of creating lots of rosti at the same time that are all the same shape – perfect for a party canapé.

Potato Rosti (makes enough for about 12 muffin tin sized rosti – depending on the size of the potato – you might get a few more)

Rosti illustration for rosti and caviar canapé recipe2 baking potatoes
1 large white onion
Salt and pepper
Vegetable oil (about 1 tbsp)
Butter (about 1 tbsp)
1 cup of sour cream
1 small tub of black caviar (I use the cheap stuff because it’s really no more than a salty accent)
Muffin tin – I find the rosti crunch up better in my metal tin

  • Pre-heat the oven to 425
  • Grate the potatoes into a bowl
  • Peel the onion, cut in half and grate into the bowl
  • Season generously with salt and pepper
  • Tip into a tea towel and wring out until as dry as possible
  • Wipe a thin layer of oil around the muffin tins to stop the rosti from sticking
  • Press a tbsp of potato mixture firmly into the bottom of each hole (it should come about 1cm up the side of the tin)
  • Put a tiny knob of butter on top (about ¼ tsp) – (the butter helps the rosti brown, but add to much and they’ll be greasy)
  • Bake for about 30 – 40 minutes, depending on the thickness of the potato and the size of the tin – I make mini fairy cake tin ones that take 20 mins, whereas my silicone muffin tray takes 40 and sometimes longer
  • Turn out so that the bottom is now the top
  • Top with a blob of sour cream and a little pile of caviar

If you can make that you can make this:

  • Swap out the caviar for smoked salmon
  • Or smoked fish
  • Mix chopped chives and a squeeze of lemon into the sour cream
  • Mix chopped chives a squeeze of lemon, chopped dill and chopped smoked salmon into the sour cream
  • Add a few tsp of thyme into the potato mix
  • Use garlic oil instead of the oil and butter
  • Top with crispy bacon slices and poached eggs for breakfast
  • Take the onion out of the mixture and instead cut a small red onion into rings and place a ring into the bottom of each muffin tray before topping with the potato. When you turn them out, they’ll have a dark onion ring adorning the top
