Put a large pan of salted water on to boil for the pasta.
Meanwhile, heat the oil in a large frying pan (skillet) over a medium heat. Add the chorizo and cook for 5–6 minutes, stirring often, until lightly browned and slightly crisp. Remove from the pan with a slotted spoon and place in a bowl. There will be oil left in the pan from cooking the chorizo.
1 tablespoon olive oil, 200 g (7oz) chorizo, chopped into
By now the water for the pasta should be boiling. Cook the bucatini, as per the packet instructions (usually about 10 minutes). Once cooked, drain, reserving a cup of the cooking water.
300 g (10½oz) bucatini
Meanwhile, add the onion, salt and pepper to the frying pan with the chorizo oil and cook for 5 minutes, stirring often, until the onion starts to soften.
1 onion, 1/4 tsp salt, ½ tsp ground black pepper
Add the garlic, chilli flakes and tomato purée. Cook for a further 2 minutes, stirring.

Add the canned tomatoes and stock. Bring to the boil and then simmer for 5 minutes.
400 g (14oz) can finely chopped tomatoes, 120 ml (½ cup) chicken stock
Add the cooked chorizo back to the frying pan, along with the drained bucatini and Parmesan. Stir together and heat for another 2 minutes. Add splashes of the pasta cooking water if you want to loosen the sauce.

Notes
Swap out the bucatini for your favourite pasta. Tagliatelle or linguine work really well.
