While you prepare the sauce, cook the pasta according to the package directions.

Cook the onion and garlic in butter until translucent. Once the garlic is cooked, mix in the tomatoes. Then, mix in vodka.

Simmer the sauce for ~7-10 minutes on medium heat or until the vodka is cooked off. If you are using a more liquid form of tomatoes like canned tomatoes, reduce the tomato down first.

Mix in the chilli flakes, cream, and parmesan to thicken the sauce. Simmer for another few minutes. Season with salt and pepper.

Once the sauce is done cooking, mix the pasta in the sauce.

Serve with additional parmesan cheese on top and basil as a garnish.
