Cook the pasta according to the directions on the box. Aim to have it ready around the same time as the sauce.
Cook the onions in a skillet, then add the garlic, followed by the celery and carrots. Sauté for 5 minutes.
Increase the heat and add the ground beef. Cook for about 10 minutes, breaking it up as it browns.
Add the tomatoes and herbs to the ground beef mixture. Season with salt and pepper and simmer for 25 minutes.
Serve the Bolognese sauce over the cooked rigatoni. Top each plate with a sprinkle of pecorino romano and fresh parsley.
