Begin by thinly slicing the 4 garlic cloves and set aside.
Bring a pot of water to boil, and add a pinch of salt. Add the dry spaghetti and cook till al dente (about 10-12 minutes). Follow instructions on packet for best results.
In a pan, heat the olive oil over a small fire/heat and add the sliced garlic. Add a pinch of salt and the red chili flakes. The garlic should be sizzling very lightly, and toss occasionally to ensure they don't burn.
Once the pasta is cooked, toss directly into the garlic, chili, oil mixture. Mix well and allow the pasta to be well coated.
Garnish with some parsley and serve!
