Once the war ended, Krukowski emigrated to Great Britain and the United States. For eight years, he also lived in Argentina, running the music theatre El Nacional together with the composer Jerzy Petersburski. He also worked as the director of the Polish-language Teatr Rozmaitości in Buenos Aires (in 1952 the institution changed its name to Nasz Teatr). After returning to Poland in 1956, Krukowski found employment as the director of Teatr Syrena in Warsaw. In 1959, he also started holding this position in Teatr Buffo. In the 1960s, the café in Hotel Bristol, one of the capital's finest establishments, became the venue for Krukowski's cabaret U Lopka, with performers including Barbara Krafftówna, Bohdan Łazuka and Iga Cembrzyńska.
His memories of the lively pre-war years were published in the books Moja Warszawska (1968) and Mała Antologia Kabaretu (1982). In Z Melpomeną na Emigracji, published posthumously in 1987, Krukowski described his artistic war-time experiences.
The artist was decorated with the Order of Polonia Restituta and the Cross of Merit with Swords. He died in Warsaw, where he is buried next to his wife, the actress Władysława Krukowska, in the Powązki Cemetery.
