04 - 2 tbsp fresh parsley, finely chopped

# Method:

01 - Place grated celeriac and potato in a clean kitchen towel and squeeze firmly to remove as much liquid as possible.
02 - In a large mixing bowl, combine the squeezed celeriac, potato, grated onion, parsley, flour, egg, salt, and pepper. Mix thoroughly until all ingredients are evenly distributed.
03 - Heat 1½ tbsp olive oil in a large non-stick frying pan over medium heat. Scoop a heaped tablespoon of mixture per rösti and gently flatten in the pan. Fry in batches for 4–5 minutes per side until golden and crispy, adding additional oil as needed. Transfer cooked rösti to a paper towel-lined plate and keep warm.
04 - In a small bowl, combine Greek yogurt, harissa paste, lemon juice, and salt. Mix until well blended and adjust seasoning to your preference.
05 - In a clean pan, heat butter or oil over medium heat. Crack eggs into the pan and fry to your desired doneness. Season with salt and pepper.
06 - Arrange cooked rösti on serving plates. Top each rösti with a dollop of harissa yogurt and a fried egg. Garnish with chopped parsley and serve with lemon wedges.

# Expert Advice:

01 -
  • The celeriac brings this subtle, almost nutty depth that makes people pause mid-bite and ask what that flavor is.
  • You get that satisfying crispy-outside, tender-inside texture with actual vegetables doing the heavy lifting instead of relying on potatoes alone.
  • Harissa yogurt is your secret weapon—it transforms breakfast into something that feels restaurant-worthy but takes five minutes to make.
  • Fried eggs on top mean you can eat this for breakfast, lunch, or a casual dinner without anyone questioning your choices.
02 -
  • The single biggest mistake is not squeezing out enough moisture from the grated vegetables—your rösti will steam instead of fry, and you'll end up with a soggy, deflated patty that breaks apart.
  • Don't trust harissa straight from the jar; always taste a tiny bit first because some brands are absolutely fiery while others are almost sweet, and you need to know what you're working with.
  • If your rösti falls apart when you flip it, your oil wasn't hot enough or you tried to flip too early—wait until you see golden brown on the bottom, not just light tan.
03 -
  • Add a tablespoon of cornmeal to the mixture if you're chasing extra crunch—it won't change the flavor but it adds this subtle texture that people notice and love.
  • Sweet potatoes work beautifully if you want something sweeter and slightly earthier; just make sure to squeeze out even more liquid since they're naturally wetter than regular potatoes.
  • Make the harissa yogurt up to an hour ahead and let it sit in the fridge so the flavors have time to meld together properly.
