Hello lovelies,

rösti is a little piece of home for me. On Sundays there is often a big pan on our stove, and this time I gave the classic rösti a twist: this sweet potato rösti is made half from sweet potatoes, so it tastes gently sweet and takes on a beautiful orange color. On top go melted Gruyère and a fried egg.

Sweet potatoes end up in my shopping basket all the time in the fall. Besides the rösti, I especially love them in my sweet potato quiche with spinach and feta, another brunch favorite.

The secret of a crispy rösti

Squeezing is what matters most. Put the grated potatoes in a clean kitchen towel and press out as much liquid as you can. The drier the mixture, the crispier the rösti and the better it holds together when you flip it. The regular potatoes matter here, because their starch binds the strands.

When things need to go faster during the week, I like to make my savory chickpea pancakes with vegetables instead of rösti. The batter is mixed in no time, and you do not even need a grater.

For me a fried egg simply belongs on a rösti. If you cannot get enough of it, my savory crêpes with vegetables and fried egg are a second brunch idea.

To flip it, I place a large plate on the pan, turn everything over in one confident move and slide the rösti back into the pan pale side down. It sounds braver than it is, and after the first time it works all by itself.

And if you have sweet potatoes left over, try my sweet potato risotto with dried tomatoes. I would love to hear how the sweet potato rösti turned out for you.

Yours, Verena

TIPS

Verena's notes

Tip from my kitchen: keep the first rösti warm in the oven at 80°C (176°F) while the second one fries, so both reach the table at the same time. In the photos I dusted the fried eggs with a little paprika, which looks pretty and suits the sweet potato. Serve a green salad on the side if you like. The rösti is just as good without cheese, simply leave out the Gruyère.

INSTRUCTIONS

Prepare the potatoes

  1. Peel the sweet potatoes and potatoes and grate them on a coarse grater.
  2. Put the grated potatoes in a clean kitchen towel and squeeze firmly to remove as much liquid as possible.
  3. Finely chop the onion and mix it with the grated potatoes in a large bowl.
  4. Wash the thyme and pick the leaves off the sprigs.
  5. Add the salt, pepper, paprika and half of the thyme and mix everything well.

Fry the rösti

  1. Melt 1 to 2 Tbsp of butter in a large frying pan over medium heat.
  2. Add half of the potato mixture and press it flat with a spatula.
  3. Fry for 10 to 15 minutes until the underside is golden.
  4. Place a large plate or lid on the pan and turn the pan over so the rösti lands on the plate.
  5. Add a little butter to the pan and slide the rösti back in with the uncooked side down.
  6. Fry for another 10 to 15 minutes. Toward the end, sprinkle half of the cheese over it and let it melt under a lid.
  7. Fry a second rösti the same way with the remaining potato mixture and cheese.

Fried eggs and serving

  1. Heat a little butter in a second pan and fry 2 to 4 eggs, as you like.
  2. Top the rösti with the fried eggs, sprinkle with the remaining thyme and serve right away.

GOOD TO KNOW

Frequently asked questions

  • Usually the mixture is too wet, or the rösti was flipped too early. Squeeze the grated potatoes out firmly and only flip once the underside is golden and firm after 10 to 15 minutes. A nonstick pan helps too.

  • For rösti from raw potatoes I use mostly waxy varieties. They hold their shape as they fry and have enough starch to bind the grated sweet potato. Floury potatoes turn soft and mushy more quickly.

  • Yes, but it holds together less well, because sweet potatoes contain less binding starch. In that case mix 1 Tbsp of cornstarch or 1 egg into the mixture and fry 4 small rösti instead of 2 large ones.

  • Gruyère, Appenzeller or a flavorful alpine cheese melt beautifully and suit the gentle sweetness perfectly. If you eat strictly vegetarian, look for cheese made with microbial rennet, because many traditional hard cheeses are made with animal rennet.

  • Grate the potatoes just before frying, otherwise they turn brown. Keep the first rösti warm in the oven at 80°C (176°F) while the second one fries. Leftovers can be fried crisp again in the pan the next day.
