Step-by-Step Instructions

Step 1: Cook and dry the potatoes

Place the whole, unpeeled potatoes in a large pot and cover with 4 qt (3.8 L) cold water. Add 2 tbsp (30 g) kosher salt. Bring to a boil, then reduce to a steady simmer and cook until a knife slips in easily, 20–25 minutes. Drain well. Return potatoes to the hot pot and let them steam-dry over the residual heat for 3–5 minutes. This drives off moisture for lighter dumplings.

Step 2: Rice and cool

While still warm enough to handle, peel the potatoes (the skins should slip off easily). Rice them through a potato ricer onto a baking sheet or mash very smoothly, avoiding lumps. Spread into an even layer and let cool until just warm to the touch, about 10 minutes. Cooler potatoes absorb less flour, so resist rushing this step.

Step 3: Make the dough

Scrape the cooled potatoes into a large bowl. Add the egg, 1 tsp fine sea salt, and the pepper. Sprinkle 1 1/3 cups (170 g) flour over the top. Using a fork or your hands, gently fold until a soft dough forms. If it clings to your hands, dust in 1–3 tbsp more flour—only as much as needed. Do not knead heavily; overworking develops gluten and makes kopytka tough.

Step 4: Shape the dumplings

Lightly flour your work surface. Divide dough into 4 pieces. Roll each into a rope about 3/4 inch (2 cm) thick. Cut into 1-inch (2.5 cm) pieces on a slight diagonal to echo the traditional “little hoof” shape. If you like, lightly press each piece with the back of a fork to create ridges. Arrange on a floured tray and dust the tops so they don’t stick.

Step 5: Boil in batches

Bring a large pot of well-salted water (it should taste like the sea) to a gentle simmer, not a hard boil. Add a batch of kopytka, stir once to prevent sticking, and cook until they float, then 1 minute more (about 2–3 minutes total for each batch). Lift out with a slotted spoon to a lightly oiled tray. Repeat with remaining dumplings.

Step 6: Option A — Buttered breadcrumbs

Melt 4 tbsp (56 g) butter in a large skillet over medium heat. Add breadcrumbs and a pinch of salt (and garlic powder if using). Cook, stirring, until deeply golden and nutty, 3–5 minutes. Add the hot kopytka to the skillet and toss to coat, warming 1–2 minutes. Off heat, fold in 3 tbsp parsley and lemon zest. Serve immediately with extra parsley and black pepper.

Step 7: Option B — Creamy mushroom sauce

Heat 2 tbsp butter and 1 tbsp olive oil in a wide skillet over medium-high until foaming. Add mushrooms in an even layer and cook undisturbed 3–4 minutes, then stir and continue until browned and their liquid evaporates, 6–8 minutes total. Season lightly with salt. Add shallot and cook 1 minute; add garlic 30 seconds. Deglaze with white wine; simmer until almost dry, 1–2 minutes. Stir in broth, cream, and thyme; simmer gently until lightly thickened, 4–6 minutes. Season to taste with salt, pepper, and lemon juice. Fold in hot kopytka and warm 1–2 minutes. Finish with parsley.

Step 8: Serve and enjoy

Plate kopytka generously. For the breadcrumb version, add an extra spoonful of toasted crumbs on top. For the mushroom version, spoon extra sauce and mushrooms over the dumplings. Sprinkle fresh parsley and cracked pepper. Serve hot.

Pro Tips

• Dry equals fluffy: Steam-dried, just-warm potatoes need less flour, yielding pillowy dumplings.
• Use a ricer if possible: It guarantees a smooth, lump-free base and a lighter texture.
• Add flour sparingly: Start with the measured amount and add only enough to tame stickiness.
• Simmer, don’t boil hard: A gentle simmer prevents the dumplings from breaking.
• Test one: Boil a single piece; if it holds but feels gummy, add 1–2 tbsp more flour to the dough.

Variations

• Brown butter and sage: Toss cooked kopytka in 5 tbsp sizzling brown butter with crisped sage leaves and a squeeze of lemon.
• Onion-bacon topping: Sauté 4 oz (115 g) diced bacon until crisp; add 1 small sliced onion and cook until golden. Toss with kopytka and parsley.
• Cheesy “leniwe”-inspired: Replace half the potato with drained farmer’s cheese or ricotta, reduce flour by 2–3 tbsp, and proceed as directed.

Storage & Make-Ahead

Shape kopytka and freeze in a single layer on a parchment-lined sheet until solid, 2–3 hours. Transfer to a freezer bag for up to 2 months. Cook from frozen directly in simmering salted water; add 1 minute to cook time. Cooked kopytka keep 3 days in the fridge; reheat by pan-frying in a little butter until golden. Breadcrumbs can be toasted 2 days ahead; cool and store airtight. Creamy mushroom sauce keeps 3 days chilled; rewarm gently and loosen with a splash of broth or water.
