The Ultimate Slow Cooker Spag Bol

Spaghetti bolognese is a real Italian classic. Every home chef needs a good spag bol recipe in their repertoire, and we believe that slow cooking is the best way to make this classic.

Some upfront work in the pan is important for this recipe. You need to slightly crisp the pancetta or bacon lardons, soften the veg and brown the minced beef. Reducing the wine is also important. Just remember, when slow cooking, there’s no need to use an expensive bottle wine!

We find this works equally well on a high 3-4 cook and a 7-8 hour cook. Just work out your timings for when you want to eat, then you can set and forget the slow cooker.

After the slow cook, it almost goes without saying… serve with spaghetti and plenty of parmesan cheese. A sprinkle of freshly chopped parsley goes a long way too.
