Canh khoai mỡn — Vietnamese taro soup — is a home-style dish rarely found on restaurant menus. It's a thick, comforting soup made with taro root, pork ribs, and sometimes pork offal, flavored with fish sauce and garnished with scallions. In San Diego, you're most likely to find it at restaurants that cater to homesick Vietnamese diners who want home cooking.
Phuong Trang top-pick
With over 200 dishes on the menu, Phuong Trang is your best bet for finding canh khoai mỡn in San Diego. The taro is properly soft and starchy, dissolving slightly into the broth to create that characteristic thick consistency. The pork ribs are fall-off-the-bone tender. It's served as a side soup or part of a family-style meal. Ask your server — it may be listed under "home-style soups."
Ngon Ngon To Go best-value
Ngon Ngon's takeout-focused menu includes a rotating selection of Vietnamese home-cooking dishes, and canh khoai mỡn occasionally appears as a special. The taro soup here is unpretentious and warming, exactly like what you'd get at a Vietnamese home kitchen. The advantage of Ngon Ngon is that you can grab it alongside other home-style dishes for a complete meal.
Mien Trung Restaurant hidden-gem
Mien Trung's central Vietnamese kitchen occasionally offers canh khoai mỡn, particularly during cooler months. The soup is home-style, with starchy taro that's been simmered until nearly melting, tender pork ribs, and a broth that's been seasoned with the right amount of fish sauce. It's comfort food, Vietnamese-grandmother style.
