Bring a pot of water to a boil and cook the pasta according to the package instructions. Adding some salt to boiling water before cooking pasta to enhance its flavour. Using a slotted spoon, transfer the pasta and drain well.
In the meantime, heat a large frying pan over medium-high heat, melt the butter and warm up the oil. When hot, sauté the garlic until slightly brown and add the pancetta. Continue for a few minutes then add the broccoli rabe. Continue sautéing until broccoli pieces are tender. Adjust with pepper.
Add the pasta into the broccoli mix and combine gently until the pasta is well coated with the mixture.
Transfer to a platter. Sprinkle with the pomegranate seeds and Parmesan. Serve hot.
