1 tablespoon minced fresh sage leaves, plus whole leaves for garnish
Directions
In a large pot or Dutch oven, heat the olive oil over medium-high heat. Add the pancetta, carrot, celery, and onion, and cook until softened, about 5 minutes. Add the tomato paste and mix into the vegetables until well combined. Add the rosemary and garlic and cook until fragrant, about 2 minutes.
Drain the soaked beans and add to the pot along with the chicken broth. Bring to a boil, then reduce the heat to a simmer. Add the rind of Pecorino Romano.
Cook, stirring occasionally, until the beans are tender, about 40 minutes. Mash some of the beans with the back of a spoon.
Add the pasta and minced sage and cook another 10 minutes until pasta is al dente. Add more broth as needed.
Season with salt and pepper to taste. Sprinkle with whole sage leaves and grate cheese on top to serve.
