Method
Heat the olive oil in a large pan. Soften the onion and carrots for 7–8 minutes, then stir in the garlic.
Add the beef mince and cook until browned throughout, breaking up any lumps.
Stir in tomato purée, tomatoes, stock and oregano. Simmer uncovered for 30 minutes, stirring occasionally.
Cook the spaghetti in salted boiling water according to the packet. Reserve a splash of pasta water and drain.
Toss pasta with the sauce, loosening with pasta water as needed. Serve with Parmesan.
