A hearty Valtellina mountain mash of roughly crushed boiled potatoes and green beans, enriched with nut-brown butter and onion and finished with melting Valtellina Casera DOP, served hot as a main or alongside local salumi.
Taroz is the protein-and-starch staple of Valtellina's alpine herding culture, made wherever potatoes, green beans, and Casera cheese were available from the mountain huts above Sondrio. The dialect name derives from the verb meaning 'to mash and stir together,' which describes the preparation exactly. Mountain shepherds boiled summer potatoes and green beans in the same pot and combined them with Casera from the alpine huts—a calorie-dense strategy for sustaining hard physical labor in the heights. Valtellina Casera DOP, the cheese that defines the dish, received its EU protected-origin registration in 1996 (its protection consortium having formed the year before); its very name comes from the dialect word for the alpine stone huts where it was aged.
Coarse potato-and-bean mash bound by nut-brown butter and pools of melted Casera; savory and warming, with a low sweetness from the caramelized onion underpinning the earthy starch.
Boiling gelatinizes potato starch granules, which burst and swell to produce the mash's cohesive body. Green bean cellulose resists full breakdown, maintaining textural contrast. Butter and onion undergo Maillard and Strecker reactions, releasing sulfurous aromatic compounds that form the dish's caramelized backbone. Casera's fat and casein, added last over residual heat, emulsify into the starchy base, binding the mash into a glossy, unified mass.
Variations
Borlotti beans replace green beans in some versions for a more robust legume flavor. Lard substitutes butter in the most traditional mountain renditions. A handful of Parmigiano-Reggiano reinforces savoriness. Served alongside Valtellina cured meats, the dish becomes a complete mountain meal.

Ingredients
Serves 4How it's made
7 steps · 15 min
- 15 min
Peel potatoes and cut into 3 cm cubes; trim green beans and cut into 4 cm lengths.
- 215 min
Bring a large pot of salted water to a boil; add potatoes and cook for 15 minutes until just tender.
- 310 min
Add green beans to the same pot and continue boiling for 10 minutes until both are fully cooked.
- 45 min
Drain the vegetables; return to the warm pot and roughly mash the potatoes while stirring the green beans through—aim for a coarse, textured mash, not smooth.
Watch outMash coarse — leave lumps and whole beans; a smooth puree loses the rustic texture that defines taroz.
- 58 min
Thinly slice the onion; melt butter in a skillet over medium heat and fry the onion, stirring frequently, until it turns deep nut-brown, about 8 minutes.
Watch outTake the onion all the way to deep nut-brown, about eight minutes — that caramelized sweetness is the dish's backbone.
- 62 min
Pour the browned onion and all the butter over the mash and fold together thoroughly.
- 75 min
Cut Valtellina Casera into small chunks, scatter over the mash, and fold gently until the cheese melts from residual heat; season with salt and serve hot.
Watch outFold the cheese in off the heat and let residual warmth melt it into strings — direct heat makes it seize and turn oily.
