For the pangrattato, heat a frying pan to medium-high heat. Add in olive oil, and once the oil is hot, add in the garlic and breadcrumbs and fry until golden. Season with a pinch of salt. You want to balance this so there is no residual oil left but the breadcrumbs are not too dry either.
Remove the fried breadcrumbs from the pan and place onto a piece of paper towel to drain any excess oil.
Bring to boil a large pot of salted water. Add spaghetti into the boiling water and stir to ensure it doesn’t stick to itself. Cook until al dente.
Heat a large frying pan to medium-high heat. To create the sauce, add olive oil to the pan and heat it until it begins to smoke. Place chilli and garlic in a medium stainless-steel bowl and pour hot oil over them.
Strain the pasta, leaving a small amount of pasta water in the pot. Combine the pasta, pasta water, sauce and parsley in the pan and mix.
Serve pasta with a drizzle of olive oil, lemon zest and a generous amount of pangrattato on top.
