Cook pasta: Bring a pot of heavily salted water to the boil and cook your pasta el dente. Follow the instructions on the back of the pasta packet for al dente pasta and drain your pasta 2 minutes before the suggested cooking time as it will continue to cook when it’s stirred through the sauce. Reserve 1/2 - 1 cup of pasta water.
Fry aromatics: While the pasta cooks, begin your sauce. In a large frypan on a medium heat, bring the olive oil to heat and fry the onions and garlic for 3 - 4 minutes or until fragrant and translucent. Stir occasionally to avoid the garlic from burning. Add the oregano and chilli flakes and fry for a further 2 minutes.
Fry tomato pasta & vodka: In the same pan on a high heat, fry the tomato paste for 2 - 3 minutes or until it has caramalised, turned a deep red colour and is almost sticking to the pan. Turn the heat to medium and add the vodka. Cook until 80% of the liquid has been absorbed.
Add cream: Add in the cream and cook for 1 minute on a medium heat or until the cream has foamed and is bubbling. Turn the heat to low and stir the cream through the sauce with a pinch of salt.
Finish sauce: Add the cooked pasta to the pan and stir through with the parmesan and butter. Slowly incorporate the pasta water until a silky and glossy texture forms. Finish off with an extra sprinkling of cheese, chilli flakes and the burrata (if using). Serve immediately.
