Pour chicken broth over onion mixture and stir until blended, 2 to 3 minutes. Add cabbage and corned beef; cook, stirring frequently, until cabbage is tender, about 20 minutes. Add half-and-half and cook just until liquid is warm but not boiling, about 5 minutes.

Stir half-and-half into the pot; continue to cook just until liquid is warm but not boiling, about 5 minutes.
