Boil spaghetti in salted water as per package directions until al dente. Reserve cup of the pasta water before draining the pasta.
While the pasta is boiling, heat a large pan or skillet and add the diced bacon to it. Cook till the bacon is slightly crisp and light brown. Remove bacon on a plate with a slotted spoon, reserving bacon fat in the pan. Leave the flame on.
Add olive oil to the pan, if using, along with the chopped garlic. Saute for a minute or so and add the chili flakes. Cook for 30 seconds and add the reserved pasta water. Bring this to a boil and continue boiling till the liquid reduces by half.
Add spaghetti, salt and bacon to the pan, and cook till the liquid is reduced to a thick sauce which coats the pasta. Stir in parsley and let it rest for five minutes before serving.
