Heat 2 tablespoons olive oil in a skillet. Add the onion and sauté until soft and translucent, but not browned, about 3 to 5 minutes. Add a little water to the skillet if needed (this will stop the onions from browning).
Add the chicken livers and white wine. Add the garlic, sage and rosemary. Season with salt and pepper. Simmer a few minutes until the chicken livers are no longer pink.
Add the remaining 2 tablespoons olive oil and toss to combine.
Drop the fresh pasta into the boiling water. Cook until al dente, about 2 minues. Add the pasta to the ragù and toss to combine. Add a little pasta water if needed to loosen the sauce.
Divide amongst bowl. Grate some Parmesan on top of each bowl and serve. Enjoy!
