- 12 chipolata sausages

- 600g floury potatoes, (e.g. Maris Piper or King Edward ) cut into chunks
- 400g tin chopped tomatoes (best quality you can afford)
- 200ml hot chicken or vegetable stock (1 stock cube)
- 3 tbsp tomato purée
- 1 tsp dried mixed herbs
- Salt and freshly ground black pepper

Method
- Brown the onions
Heat 1 tablespoon of oil in a large non-stick frying pan over medium-high. Toss in the sliced onion, letting it soften and get a hint of colour for about 4 minutes. This step kicks off loads of flavour, so don’t skip! - Sear the sausages
Tip the onions into your slow cooker, then pop another tablespoon of oil into the same pan. Add the sausages and fry for 4–5 minutes until they’re golden all over. If doing batches, just scoop them across as you go. - Prep the veg
While the sausages are browning, chop the carrots and potatoes. Add them to the slow cooker along with the chopped tomatoes. - Mix the sauce
In a bowl, blend the hot stock with tomato purée and dried herbs. Season generously with salt and pepper, then pour this mixture into the slow cooker. - Add sausages – No stirring!
Lay the browned sausages on top of the veg and tomato mixture, but don’t stir them in. This trick helps them keep their shape and colour. - Slow cook
Pop on the lid. Set to high for 5–6 hours or low for 7–9 hours. You’ll come back to a kitchen that smells absolutely delicious. - Finish and serve
Give everything a gentle stir before serving. Taste for seasoning and adjust if needed. Ladle portions into bowls and enjoy every comforting bite!
Here’s an easy tip: Leftovers taste even richer the next day. Store in the fridge and reheat gently.
