01. Boil the squid ink spaghetti for 10-12 minutes in salted water. Whilst the pasta is boiling, place the chopped onions and half of the butter in a frying pan and cook on a low-medium heat until the onions soften.
02. Add the rest of the butter, chopped garlic, chilli and prawns and cook on low-medium until the prawns turn pink. Avoid burning the garlic.
03. Add the spaghetti to the frying pan and mix to combine the sauce with the spaghetti. Serve immediately with a squeeze of fresh lemon juice and a sprinkle of parsley. Season with salt and pepper to taste.
