Slow Cooker Sausage Casserole Ingredients
- 2 tsp sunflower oil
- 450g pork sausages (6 to 8)
- 1 large red onion, chopped
- 3 cloves garlic, crushed
- 800g tinned chopped tomatoes
- 400g tinned cannellini beans, drained and rinsed

How to Make Slow Cooker Sausage Casserole
- Brown the sausages: Heat the oil in a large frying pan over medium-high heat. Cook the sausages until browned on all sides, then set them aside.
- Load the slow cooker: Place the browned sausages in your slow cooker. Add the onion, garlic, chopped tomatoes, cannellini beans, tomato purée, Worcestershire sauce, cumin, smoked paprika, stock cube, and carrots.
- Stir and season: Mix everything together until well combined. Season with salt and black pepper. Secure the lid.
- Cook low and slow: Cook on high for 6 hours or on low for 8 hours, until the carrots are tender and the sauce has thickened.
- Serve: Stir well before serving. Cut the sausages into bite-sized pieces with kitchen scissors if you prefer. Ladle into bowls and serve hot.
What Are the Best Tips for Slow Cooker Sausage Casserole?
- Always brown the sausages first: This takes five minutes but adds a huge amount of flavour. It also gives the sausages a firmer texture so they hold their shape during the long cook.
- Choose the right sausages: A good quality pork sausage like Cumberland or Lincolnshire works best. They have a high meat content and hold together well in the slow cooker.
- Add chorizo for extra flavour: Chop about 100g of chorizo and brown it with the sausages. It adds a smoky, spicy depth to the whole casserole.
- Swap the beans: Cannellini beans work well here, but butter beans, haricot beans, or chickpeas are all good alternatives. For a meat-free version, try our vegetarian sausage casserole.
- Skip browning on busy days: If you are short on time, add the raw sausages straight to the slow cooker. The flavour will be milder but the casserole will still taste great.

What Should You Serve on the Side?
This casserole is filling enough on its own, but a few sides make it even better. Creamy mashed potatoes or fluffy white rice will soak up the smoky sauce. A jacket potato is another great option for a bigger meal.
For something lighter, serve with steamed green beans or peas to add colour and freshness. A thick slice of crusty bread or a warm dinner roll is perfect for mopping up the last of the sauce. If you want a starter, a bowl of leek and potato soup pairs well. For another hearty main, try the beef stew and dumplings.
How Should You Store Leftovers?
Let the casserole cool completely, then transfer to an airtight container. It keeps in the fridge for up to 3 days. Reheat in a saucepan on the hob over medium heat, or microwave for 3 to 4 minutes, stirring halfway.
This casserole freezes very well for up to 3 months. Portion into freezer-safe containers before freezing. Thaw overnight in the fridge, then reheat thoroughly on the hob until piping hot.
