Heat a large saucepan on low heat and add olive oil
Add the onion, carrots, celery, garlic and the thyme leaves. Fry for about 10 minutes until it softens.
Increase the temperature to medium-high heat and add the mince, stirring until it browns
Add the tomatoes, dried herbs, bay leaf, tomato puree, chilli powder, stock cube and pepper. Add more salt only if required as the stock may have enough salt. Bring to the boil, reduce and let it simmer for an hour to an hour and a half. You will have a rich, thick sauce
When the sauce is almost cooked , add in your cream. Boil the spaghetti and mix into the sauce. Serve with a sprinkling of parmesan and basil leaves
