Finely chop the onion, cut the sausages in half and cut the brisket into large chunks.
Add 1-2 tablespoons of olive oil to a large pot and brown the meat on all sides. Use tongs to help you move the meat around for browning.
Once browned, add the finely chopped onion to the meat. Arrange everything so the onion is at the bottom and saute it until soft (about 5 minutes).
Next, add the passata, a pinch of salt and the fresh basil. Cover with a lid and let the ragu simmer gently for 3 and a half hours. Make sure to check the ragu every now and then and give it a stir to stop it from catching on the bottom.
After cooking turn off the heat and serve. See our serving suggestion in the notes.
