  • 400 grams Spaghetti
  • 6 Strips Bacon diced
  • 1 teaspoon Olive Oil optional
  • 6 - 7 Cloves Garlic finely chopped
  • 3/4 teaspoon Chili Flakes
  • 1/4 cup Parsley fresh , finely chopped


  • 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.
