I find keeping the fat of the meat to add it into the sauce adds so much more flavor. Sounds delicious though.
How I do mine is pretty unhealthy but it's really delicious. I pan fry an onion for a little bit, add in the ground beef, salt and pepper, once that's done, I fry garlic with chili flakes, tomatoes, oregano, basil, add in the meat with the fat juice, I had tomato sauce with a couple bay leaves...let it warm up for couple minutes and then simmer.
I add in a little bit of milk, butter and parmesan to give it a bit of a creamy texture but not too much.
It's so good.
