We used coarsely ground beef cheek, which makes an exceptional sauce — but it needed a full 3 hours of simmering to fully break down. If you use ground chuck, plan on 2½ hours total. The longer it goes, the better it gets either way.
Whole milk stirred in near the end and cooked until evaporated is what makes bolognese silky rather than acidic. It’s counterintuitive but essential to the authentic recipe. Don’t leave it out and don’t add it early.
This batch is spoken for — two rigatoni nights and the stuffed peppers use all of it. If you want a freezer stash, make a double batch and freeze the second half in zip-lock bags. Bolognese keeps in the freezer for 3 months and thaws overnight in the fridge. This is a Sunday project that pays dividends all week.
