Step 1

Put the mince and onion in a large non-stick frying pan and fry together over a medium–high heat for about 4 minutes, stirring and squishing against the side of the pan with a couple of wooden spoons to break up the mince as much as possible.

Step 2

Add the garlic and cook for 1 minute more.

Step 3

Tip the mince and onions into the slow cooker and add the mushrooms, tomatoes, stock, tomato purée and herbs. Season with salt and lots of freshly ground black pepper.

Step 4

Cover the slow cooker with its lid and cook on high for 4–5 hours or low for 6–8 hours.

Step 5

When ready, serve the Bolognese sauce with freshly cooked spaghetti, some grated cheese and basil, if you like.
