Bolognese is not grey mince in a jar of sauce. It is browned beef, a slow simmer, and enough time for the fat and tomato to become one thing. Lean Beef Mince 400g is a pan for two to three. Fresh Lean Beef Mince - 2x 400g is the week-night double pack. Five 400g packs or the dry-aged burger mince are for batch cooking. Shop lean beef mince and beef mince for the full set.
Brown it properly
A 400g pack wants a wide pan, not a tiny saucepan. Heat oil, add the mince in a single layer, and leave it alone for 3 to 4 minutes so it actually colours. Break it up, stir, and brown another 3 minutes. If you stir from the first second you get steamed grey crumbs and a watery sauce that never tastes of beef. Salt after the first colour, not before, or the meat weeps. A chopped onion, carrot and celery go in next, 8 minutes until soft, then garlic, tomato puree, and a tin of tomatoes or a carton of passata. A splash of milk is the old Italian trick to soften the acid; a splash of stock if it looks tight.
Simmer times
Forty-five minutes at a lazy bubble is the minimum. Ninety minutes is better. Lid ajar, stir every 15 minutes, add a splash of water if it catches. You are not trying to reduce it to paste; you want a sauce that coats pasta without a puddle. If you used Fresh Lean Beef Mince - 5 x 400g and browned in two batches, simmer in a big pot and freeze in 400g tubs. Lean mince will look less oily than supermarket 20% mince; that is the point. If the sauce seems dry, it needs time and a little liquid, not a lump of butter.
The dry aged mince pack is a richer Bolognese if you want burger-shop depth in a pasta sauce. Same method, same times; it will brown faster because of the fat, so watch the pan.
What not to do, and what to serve
Do not dump raw mince into cold sauce. Do not cook it for ten minutes and call it done. Tagliatelle or a thick spaghetti, not a soup pasta. Leftovers are better on day two, and they freeze for three months. If you want chilli or cottage pie from the same shop, the same 400g packs work; Bolognese is just the long tomato version of a well-browned mince. From fresh beef you can add a small diced pack if you want a mixed sauce, but mince is the texture Bolognese wants.
Brown, simmer, wait. That is a butcher’s Bolognese, and it starts with the right 400g pack, not a pale supermarket tray.
