A storied Lomellina risotto in which frogs caught from the rice-paddy irrigation channels are long-simmered into a golden broth, then boned; the meat and stock together build a Carnaroli risotto finished with white wine, butter and Grana Padano — a peasant classic still celebrated at Sartirana's September Sagra della Rana.
The Lomellina plain (Pavia province) sits at the heart of Italy's rice belt; its paddy fields and irrigation ditches historically teemed with frogs. Specialist frog-hunters, the Ranè of Magherno, worked the marshes nocturnally to supply Milan and Pavia markets by dawn. As early as 1474, Bartolomeo Platina's De honesta voluptate — which drew on the recipes of Maestro Martino da Como — documented frog cookery in the Po Valley; the creatures were the peasant worker's lean-protein substitute for meat on fast days. The marriage of frog with locally grown rice was organic: by the 19th century risotto con le rane was the showpiece of Lomellina wedding feasts and harvest banquets. Widespread pesticide use after the 1950s decimated wild frog populations, turning the dish into a celebrated rarity; Sartirana Lomellina keeps the memory alive with its annual September sagra.
Faintly gamey, mineral-sweet broth underlies every grain; the boned frog meat is tender and mild as rabbit, dissolving into the velvet of a butter-finished mantecatura.
Simmering whole frog carcasses draws collagen from cartilage and connective tissue into gelatin, building natural body in the stock. Carnaroli rice has a high amylopectin-to-amylose ratio; as hot broth is absorbed ladle by ladle, starch granules gelatinize progressively and release free amylose that thickens the cooking liquid. Off-heat mantecatura folds cold butter into the starch-thickened liquid, forming a stable oil-in-water emulsion that coats each grain without added cream.
Variations
Some Lomellina cooks finish with lemon zest and flat-leaf parsley for brightness. A drier version uses only boned frog meat with a vegetable soffritto and no separate broth step. Fried frog legs served alongside the risotto — as at the historic Torradello trattoria — represent the older restaurant format.

How it's made
7 steps · 30 min
- 110 min
Clean and skin the frogs; separate the legs from the bodies, setting both aside.
- 245 min
Place frog bodies in cold water with onion, carrot, celery and parsley; bring to a simmer and cook 45 minutes; strain the broth and keep hot over low heat.
Watch outKeep the frog stock at a gentle simmer, not a hard boil — a rolling boil turns it cloudy instead of drawing clean gelatin from the bones.
- 310 min
Bone the meat from the simmered legs and bodies; reserve.
- 45 min
In a wide saucepan, sauté finely diced white onion in butter over medium heat until translucent; add the boned frog meat, season and sauté 2 minutes.
- 53 min
Add Carnaroli rice; stir and toast until the grains turn opaque, about 2 minutes; deglaze with dry white wine and stir until absorbed.
- 618 min
Add warm frog broth one ladle at a time, stirring constantly, waiting for each addition to absorb before adding the next; cook 16–18 minutes until the rice is al dente.
Watch outAdd broth one ladle at a time and wait until each is absorbed before the next — this is what coaxes the starch out for creaminess; the rice should finish al dente.
- 73 min
Remove from heat; fold in cold diced butter and grated Grana Padano vigorously (mantecatura); cover and rest 1 minute, then plate immediately.
Watch outBeat in the cold butter off the heat, hard and fast — the vigorous stir is what emulsifies it glossy; on the flame it splits into grease.
