A large baking potato roasted whole until the skin crisps, then split open and the steaming flesh mashed right in the jacket with butter and shredded kaşar cheese into a smooth, salty base. The potato is then heaped with a long row of cold and warm toppings chosen at the counter — sweetcorn, pickles, olives, Russian salad, sausage, sautéed vegetables — and finished with squeezes of ketchup and mayonnaise. It is Istanbul's defining street snack, sold from glass-fronted carts along the Ortaköy waterfront.
The word kumpir traces through the Balkans to the German Kartoffel, a marker of the dish's roots in southeastern European baked-potato cookery rather than old Ottoman cuisine. Its modern Turkish form took shape in the Ortaköy district on the European shore of the Bosphorus, where stuffed-potato carts proliferated in the early 1990s and turned a humble baked potato into a build-your-own street meal. From Ortaköy the format spread to seaside promenades and squares across Turkey over the following two decades. It is a recent street-food creation, not a traditional regional dish.
The skin crackles and the inside is pure cloud — whipped potato gone glossy with butter and stringy with melted kaşar before a single topping lands. Then comes the chaos: cold tang of pickles and corn, salt of olives and sausage, the slick of two sauces, all forked up together with the warm cheesy base. No two mouthfuls are the same, and it is eaten straight from the foil with a plastic fork, leaning on the seawall.
Everything depends on mashing the flesh while it is still oven-hot: the residual heat is what melts the shredded kaşar into long strands and lets the butter emulsify into a smooth purée rather than a lumpy mash. The skin must be baked dry and firm — often given a final blast or a turn on a hot plate — so it holds its shape as an edible bowl under a heavy, wet load of toppings. Cold toppings go on last and unmixed so they keep their crunch against the warm base instead of going limp.
Variations
The Ortaköy waterfront stalls are the reference, offering twenty or more toppings; a basic version stops at butter, kaşar and corn, while a loaded one piles on sucuk, Russian salad, sautéed mushrooms, peas, pickled cabbage and several sauces. Some carts offer a spicy build heavy on jalapeño and sucuk; a vegetarian build skips the sausage entirely. Outside Istanbul the topping range narrows but the buttered cheese base stays constant.

Ingredients
Serves 2How it's made
6 steps · 1 hour 10 min
- 160 min
Scrub large baking potatoes, prick the skins and bake whole at 200°C until the skin is crisp and the inside is fully soft.
Watch outBake until the skin is genuinely crisp and firm — it has to hold as an edible bowl under a heavy wet load, so a soft, pale skin will slump and leak.
- 22 min
Slit each potato lengthwise without cutting through the base, opening it like a pocket.
- 34 min
Add a knob of butter and a handful of shredded kaşar to the hot flesh and mash it inside the skin until smooth and stringy.
Watch outMash the butter and kaşar into the flesh while it's still oven-hot — the residual heat is what melts the cheese into long strands; let it cool and you get a lumpy mash.
- 42 min
Season the base with salt and spread it level to form a bowl.
- 54 min
Spoon over the chosen toppings — sweetcorn, pickles, olives, Russian salad, sausage, sautéed vegetables — in rows.
- 62 min
Finish with ketchup and mayonnaise and serve straight away in foil with a fork.
