Arroz Mamposteao

It is a Puerto Rican comfort dish made by sautéing day-old white rice with stewed beans, sofrito, and garlic. It was born as a practical way to repurpose leftover rice and beans into a new, hearty meal.

Puerto Rican stewed pink beans (habichuelas guisadas) are the classic choice, though red kidney beans are also common. The beans are simmered with sofrito, tomato sauce, and seasonings before being folded into the fried rice.

Day-old refrigerated rice is strongly preferred because it is drier and fries up into separate, lightly toasted grains. Freshly made rice tends to turn soft and mushy in the pan, the same problem that plagues fried rice generally.

Arroz con gandules cooks raw rice and pigeon peas together in one pot with sofrito, while mamposteao combines already-cooked rice with already-stewed beans in a skillet. Mamposteao also typically uses pink beans rather than the pigeon peas central to arroz con gandules.

A Puerto Rican sofrito built on ajíces dulces (sweet peppers), culantro (recao), garlic, onions, and peppers is the flavor backbone of the dish. Jarred brands like Goya sofrito are a common shortcut in Puerto Rican households.
