A Rio de Janeiro steakhouse institution: a thick-cut filet mignon seared in butter and crowned with a generous heap of golden fried garlic chips. It comes plated with white rice, farofa (toasted cassava flour), batata portuguesa (par-boiled then fried potato rounds), and often a fried egg. The fried garlic is the whole point — pungent, crisp and nutty against the rich beef. It remains one of the defining lunch-counter dishes of the old Carioca downtown.
The dish is firmly Carioca and most associated with Restaurante Cosmopolita in Rio's Lapa district, which opened in 1924 and earned the nickname 'Senadinho' (Little Senate) as a haunt of politicians and diplomats during the Getúlio Vargas era of the 1930s and 1940s. It is named for Oswaldo Aranha (1894-1960), the Rio Grande do Sul statesman who served as Vargas's Minister of Finance and later Foreign Minister, and who in 1947 presided over the UN General Assembly session that voted on the partition of Palestine. By the traditional account he ate regularly at Cosmopolita and liked his steak topped with plenty of fried garlic; staff began calling the plate by his name and the kitchen added it to the menu. The naming story is folklore rather than documented fact, and the rival Café Lamas (founded 1874) also claims paternity. What is consistent across sources is the Vargas-era Rio setting and that the cut, originally rump (alcatra), later standardized to filet mignon.
A tall medallion of filet mignon, seared dark outside and pink within, hidden under a mound of garlic sliced thin and fried to pale gold. Each chip is crisp and snaps with a sweet-pungent, faintly nutty bite that cuts the buttery beef. Around it sit fluffy white rice, the dry toasty crumble of farofa, and crisp-edged rounds of fried potato; break the fried egg, when it comes, and the yolk runs into all of it. At Cosmopolita the steak arrives still sizzling in its iron skillet, butter and meat juices smoking.
The garlic carries the dish, and it is unforgiving: sliced thin and even, then fried gently at a moderate temperature, around 150C, never screaming hot. Garlic is high in sugars and low-temperature browning runs fast, so it tips from golden to bitter in seconds; you pull it pale because carryover heat keeps it darkening off the oil. The filet is seared hard in butter and a little oil to build a Maillard crust while the inside stays pink and tender, the cut prized for its softness. The Portuguese potatoes are par-boiled first so the centres cook through before the outsides crisp in the fat.
Variations
The cut has shifted over time from the original alcatra (rump) to today's standard filet mignon, with some houses using contra-filé (strip). The farofa is usually farofa de ovos, enriched with egg and onion. The fried egg on top is common but not universal. Cosmopolita and Café Lamas are the historic Rio addresses; the dish now appears on steakhouse menus across Brazil and in São Paulo.

Nail the fried garlic: sliced thin and even, fried gently at moderate heat and pulled out pale, because it keeps darkening off the oil and tips from sweet to bitter in seconds.

How it's made
6 steps · 35 min active + 10 min waiting
- 18 min
Slice 6 cloves of garlic thin and even. Fry gently in oil over moderate heat until pale gold, then lift out onto paper before they darken; they crisp as they cool.
Watch outPull the garlic the instant it turns pale gold; it will keep darkening off the heat.
- 215 min
Peel and slice the potatoes into rounds. Par-boil until just tender, drain and dry well, then fry in hot oil until crisp and golden. Salt and set aside.
- 310 min
Season the filet steaks with salt. Sear in a hot skillet with butter and a little oil, a few minutes a side, until a dark crust forms and the centre is pink. Rest briefly.
Watch outA dark crust means the pan was hot enough; the center should stay pink and springy.
- 46 min
Toast the cassava flour with a little butter, chopped onion and a beaten egg until dry, loose and golden to make the farofa.
- 53 min
Fry the eggs sunny-side up if using.
- 63 min
Plate the steak, heap the fried garlic over it, and serve with white rice, the farofa, the fried potatoes and a fried egg.
