How to Make It
In a large saucepan, heat the olive oil until shimmering. Add the onions, garlic, rosemary and crushed red pepper and season with salt and pepper. Cover and cook over moderately high heat, stirring occasionally, until just softened, about 5 minutes. Uncover and cook over moderately low heat, stirring occasionally, until the onions are very soft and lightly caramelized, about 15 minutes longer. Stir in the beans, parsley and water and simmer until stewy, about 5 minutes. Stir in the cheese and season with salt and pepper. Serve warm or at room temperature.
