You can make my delicious sausage and bean casserole using basic store cupboard ingredients – it’s so simple to throw together.

Start by browning the sausages and add them to your slow cooker. Then all you have to do is add the other ingredients and your slow cook does the rest.

Here at the Kitchen Shed we love our comfort food, whether a humble beef stew or a Madras beef curry. But when the weather is miserable outside, Slow Cooker Sausage Casserole is guaranteed to warm you up. And it’s my go to recipe for feeding a crowd on a budget.

It has gone down really well on Bonfire night alongside my Slow Cooker Jacket Potatoes. OH moans about cupboard space, but sometimes it’s really handy that I’ve accumulated three slow cookers.

Why you’ll love this recipe

Here’s why this is the Best Slow Cooker Sausage Casserole Recipe.

  • Flavour packed – sausages simmered with vegetables, beans and a spiced tomato sauce deliver a rich and satisfying casserole. Hearty enough to serve as a one pot meal, it’s a real crowd pleaser and easy on the pocket too.
  • No waste – leftovers can be kept in the fridge or frozen. Yet more good news, sausage casserole tastes even better the next day !
  • Easy to make – 10 minutes prep, add everything to the slow cooker and set and forget.
  • It’s adaptable – make it vegetarian and use meat free sausages with vegetable stock. I often use Richmond meat free sausages.

What equipment do I need ?

  • 6 to 8 person slow cooker – I used my 6.5 litre ( 7 quart ) Crock Pot.

What Ingredients do I need ?

A few staple ingredients and vegetables deliver a hearty, satisfying Slow Cooker Spicy Sausage Casserole.

Carrots, celery, passata, red onions, red peppers, beans, paprika, stockpot, thyme, garlic, tomato puree, seasoning and sausages on a work top.
  • Sausages – I used Cumberland but we also love using Richmond meat free sausages. Lincolnshire, chipolata or Toulouse, it’s entirely up to you. Any good quality sausage you have to hand will work just fine.
  • Onions – I’ve used red onion for its sweetness but feel free to swap out for brown onion.
  • Vegetables – I’ve used carrot, celery and red peppers cut into chunks.
  • White beans – I’ve used a mix of cannellini and butter beans. Haricot or even a Borlotti still deliver the goods.
  • Garlic – I’ve used freshly crushed cloves but garlic puree works well.
  • Tomato puree / paste – adds extra richness to the tomato sauce.
  • Stock – I’ve used a beef stock pot mixed with hot water. Equally, swap for a stock cube – beef, chicken or vegetable.
  • Seasoning – I’ve used freshly ground black pepper and sea salt.
  • Herbs – I’ve used freshly chopped thyme. If using dried thyme half the amount.
  • Paprika – I’ve used regular paprika to add a spicy sweet and peppery taste.

  • Brown the sausages. Browning the sausages at the beginning adds lots of extra flavour. Plus, it firms up the skin a little which helps prevent the sausages falling apart during cooking.

I don't have a slow cooker, but I cooked at low heat for a long time, and it turned out delicious. I loved the color. Paprika gives a delicate yet defined flavor. I added a pinch of cayenne pepper and OMG! This is definitely my kind of recipe!

Thanks Hayley, pleased to hear you enjoyed the flavour. We often use meat free sausages in the casserole as part of our aim to eat meat free at least four times a week and they're just as tasty.
