Begin by cooking the fettuccine pasta according to the package instructions until al dente.
While the pasta is cooking, heat a pan over medium heat and add the pancetta, cooking until it becomes crispy.
Add the chopped onion to the pan and sauté until it becomes translucent.
Once the pasta is ready, drain it and add it to the pan with the pancetta and onion.
Toss in the chopped parsley and basil, mixing everything well.
Finally, sprinkle the pecorino cheese over the pasta and serve hot.
