Hello autumn! And welcome back bonfires and woolly sweaters and casseroles my old friends.

You know I love a slow cooker recipe, but we can get stuck in a rut with the kinds of meat we’re using (if you’re indeed a meat-eater).

SO I needed to try and make a sausage casserole in the slow cooker!

Mainly because sausages are such a big hit with the whole family, are versatile, inexpensive and ideal for keeping in the freezer.

This Slow Cooker Sausage Casserole is SO GOOD on all counts.

Wholesome beans and a thick, rich tomato sauce. Totally satisfying, hearty and delicious. I hope you love it as much as we do!

How we came up with this recipe

A version of a Slow Cooker Sausage Casserole has been here on the site since 2021.

The original version included fried chorizo, which I love, but this year I really wanted to update the recipe slightly to make it more affordable. (Of course, you could still add chorizo pieces if you wanted.)

So, this recipe uses sausages and vegetables, along with cannellini beans for added nutrients, making a complete meal.

If you’d like a non-slow cooker version, you could try my tasty Sausage Casserole with Cider and Bacon, which cooks in the oven instead.


What to serve with Sausage & Bean Casserole

  • Baked potatoes
  • Rice
  • Potato wedges
  • Cous cous – Love this as it’s super speedy.
  • Add sliced chillis or chilli sauce
  • Mashed potatoes
  • Homemade chips

Slow Cooker Sausage Casserole Ingredients

  • Sunflower oil
  • Sausages – Leave them whole or chop up if you like
  • Red onion – I sometimes use pre-chopped frozen onions for speed, but you can use fresh too
  • Garlic – Same as above
  • Tinned chopped tomatoes
  • Cannellini beans – Tinned
  • Tomato puree
  • Cumin
  • Sweet smoked paprika – Be careful not to use HOT smoked paprika. The outcome will be very different! 
  • Beef stock cube
  • Carrots
  • Sea salt and freshly ground black pepper

Top tips

Sausages

I like to use sausages with a high meat content (97% if you can get it) without too many other flavourings as there’s already a lot in the sauce. If you use smaller sausages like chipolata sausages, just reduce the cooking time slightly.

FAQs

Can I cook this in the oven instead?

Sure. Cook at 160C for about an 1 hour or until the sausages is soft and tender.

Which slow cooker do you use?

I love this one (available to buy on Amazon) as it has a pan that you can use on the hob to brown your meats first and then transfer straight into the cooker. It’s very lightweight too.

Can I make this with veggie sausages?

Yes! It’s an ideal vegetarian option if you swap the pork sausages for veggie ones.

Do I really need to brown the sausages?

No, you don’t. I like to brown them for colour when serving but it’s not necessary.

Slow Cooker Sausage Casserole {EASY recipe!}

With a rich tomato and bean sauce with added veggies, this easy Slow Cooker Sausage Casserole is a hearty midweek dinner.
Prep Time: 10 minutes
Cook Time: 6 hours
Total Time: 6 hours 10 minutes
Servings: 4 People

Ingredients 

  • 2 tsp Sunflower oil, Olive oil is fine too
  • 454 g Sausages, Usually 6 or 8 sausages
  • 1 Large Red onion, Peeled and chopped. See notes
  • 3 Cloves Garlic, Peeled and crushed. See notes
  • 800 g Tinned chopped tomatoes, x2 tins
  • 400 g Tinned cannellini beans, Drained and rinsed
  • 2 tbsp Tomato puree
  • 2 tsp Cumin
  • 2 tsp Sweet smoked paprika, See notes
  • 1 Beef stock cube
  • 300 g Carrots, Peeled and chopped
  • Sea salt and freshly ground black pepper, To taste

Instructions 

  • Pan fry the sausages until browned all over. (If your slow cooker pan is the type that can be used on the hob too, you can do this in the pan.)
  • Add all of the other ingredients into the slow cooker, give it a good stir and put on the lid.
  • Cook on HIGH for 6 hours or LOW for 8 hours.
  • Stir everything well and serve. (I like to cut up the sausages using scissors before serving.)

Notes

Onions and garlic: I use pre prepared frozen, chopped here. An onion weighs about 150g, so replace with that pre chopped weight. Garlic is about 5g per clove so I use 15g (3 teaspoons).
Sweet smoked paprika: Be sure to use SWEET Smoked, not HOT. The outcome will be very different if you mix them up!
If you want to add chorizo: Simply add about 100g to the pan at the same time as you’re frying off your sausages.

    I’m officially a fan, Sarah! This is the third recipe I tried from this site and just like the previous two, this one’s perfect. So simple and so flavoursome. Already looking forward to my leftovers lunch tomorrow!

    Absolutely LOVE this recipe. I cut the sausages up before frying them off. Perfect with a jacket potato – great slow cooker winner for us.

  3. 5 stars
    Made this tonight without the celery and it was so good!!! I put the peppers in at the beginning. Was so tasty!!

  4. My not very adventurous two year just inhaled this! I could cry watching how much he was enjoying it, as we were eating exactly the same! Served with cheesy garlic flatbread – easy and delicious!

  5. 5 stars
    Delicious! Made this with a load of cocktail sausages I had picked up cheap. Great flavour. Served with potato wedges for tea and then served leftovers with melba toast as a lunch. Love how your recipes are so simple to put together but are full of flavour. Thank you.

  6. Oh my word. Put this in the slow cooker today and had this evening. Wow. Winter warning food at its best but there’s only me so I halved the amounts and I’ve still got leftovers to freeze. Very tasty and will be making again. Win win.
