Heat the olive oil and gently soften the onion, carrot, celery and garlic.
Add the beef and cook over high heat, breaking it up, until browned.
Stir in the tomato paste, then pour in the wine and let it reduce.
Add the passata, herbs and a splash of water, then simmer gently for at least 45 minutes until rich and thick, seasoning to taste.
Meanwhile cook the spaghetti in salted boiling water until al dente and drain, reserving a little pasta water.
Toss the pasta with the sauce, loosening with pasta water if needed.
Serve topped with grated Parmesan.
