Low Syn Slow Cooker Sausage Casserole | Slimming World

The first thing to mention is that the syn value of this Low Syn Slow Cooker Sausage Casserole will vary depending on the type of sausages you use. You could even make it syn free by using the Slimming World Syn-free Pork Sausages from Iceland.


For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

This classic one pot winter warmer is packed full of flavour. It’s so easy you can just throw it in the slow cooker in the morning and have it ready for dinner when you get in. You don’t even have to serve it with anything. There’s potato, butter beans and a fair bit of speed in there too. Of course there’s nothing to stop you adding even more!


This recipe makes quite a lot of casserole. So if you’re not going to use it all up in one sitting you can always keep it in the fridge for lunch the next day. Or you could pop it in the freezer and for another time.

If you use something like M&S Skinny Range sausages, which are half a Syn per sausage it means this Low Syn Slow Cooker Sausage Casserole will work out at 1 syn per portion.

However, you can use any sausage you like, just adjust the Syns accordingly.

We’ve been on the hunt for a new meat supplier for a while now. As you know, we used to use Musclefood, but not anymore! We’ve found a company that not only has a better moral compass but also has some of the best quality meat we've seen in a long time.

Protein Food Shop is a family run business, and really care about where their meat comes from. They also produce Slimming sausages that in my opinion, are the best “diet” sausages we’ve ever had.

You can grab their sausages in a few of our hamper deals, you really should give them a try.


We even have a special Sausage selection box! Their full-size sausages come in at 1 Syn each, and Chipolatas at 0.5 Syns each.

Either are PERFECT for this  recipe Low Syn Slow Cooker Sausage Casserole.

The Instant Pot

What can I say about the Instant Pot? It’s like a like a slow cooker/pressure cooker hybrid, and it’s probably one of our favourite, and most used kitchen gadgets.


If you’ve never heard of it you really should go and check it out over on Amazon. Imagine the best Slow Cooker in the world, then times that by a hundred. There’s not much that it can’t do!

It’s a slow cooker and a pressure cooker, which means you could cook recipes like this Low Syn Slow Cooker Sausage Casserole in no time at all.


Remember the pressure cookers of old that would splutter and rock, and make all sorts of scary noises? None of that with the Instant Pot. Just set the time, close the lid and let it do it’s thing. The keep warm setting can be used to keep your food hot once it’s finished cooking! How good is that?

  1. This was lovely. With the leftovers I added Spinach and extra Butter beans. Making this for taster night this week at SW!

  2. Hi,

    What is the cooking method for an instant pot? I bought one on the back of your recommendation and I’ve only cooked with it once 🙈

    Many thanks,

    1. Hi Sue
      Yes, you can use whatever sausages you prefer, frozen or fresh. Just remember to adjust the Syns accordingly

    1. Hi Stephen
      Did you mean the Instant Pot? If yes, I would brown the sausages using the saute function first, then set aside briefly while you add the other ingredients to the pot. Put sausages back in and use manual setting for about 15 minutes. Hope this helps.

    1. Hi Jasmine
      This will work well in the oven. You’ll need an ovenproof casserole dish with a lid, or you can cover tightly with foil. It will take 1 – 1.5 hrs at around 180’C fan oven.
      Just keep an eye in case you need to add any more liquid, as it will evaporate more quickly than in the slow cooker.
      Hope that helps.

    1. Hi Gayle
      You can use passata, but you might also need to add some extra speed veg to bulk it out a bit, as you’ll be losing the bulk from the tinned tomatoes. 🙂

  3. Just made this with Linda McCartney sausages at 1/2 syn each. Used veggie stock and Henderson’s relish to make a delicious filling vegan meal. Enjoyed by the whole family 🙂

    1. Hi Dave
      No, step 1 says all ingredients except the sausages, butterbeans and stock pot!
      The butter beans are added once, at step 4. 👍🏻

  4. Made this today using Heck sausages, browned them before adding with the butter beans, absolutely delicious, Thankyou for another fab recipe 😊

    1. Hi Catherine
      If you scroll down to the recipe card at the bottom, you’ll see that the sausages are added in step 2. No need to brown them first! 🙂
