Syn Free Ham & Bean Casserole | Slimming World

The campfire stew has been so popular I thought I’d share slow cooker Syn Free Ham & Bean Casserole. This one is so good the first time we made it, we had it again later on in the week.

Only this one you can speed up in the pressure cooker, making it 30 minutes instead of 5 hours. This recipe is formulated for the Instant Pot & if you’re on the market for a new slow cooker, then you might want to pick one up!

It steams, slow cooks, pressure cooks, cooks rice, you can even make cheesecake in it. It even keeps your food warm after t’s finished cooking, until you’re ready to eat. Crazy right?

You can find them on Amazon, and if you want to read more about them, head over to the Instant Pot UK Community on Facebook.


Remember to soak the dry beans over night, and then drain and give them a good rinse.

This is perfect for an SP day too! If you’re not having an SP day you can add some potatoes which will thicken it up a little more – although it’ll be pretty thick anyway.

This is a recipe that’s perfect for the freezer, just chill and freeze into portions.

  1. I made this last night for tea. I soaked the beans the night before and rinsed them off before adding them and the other ingredients to the slow cooker. It was on low for 12 hours so assumed it was cooked. Ate it for tea and me and my partner have been poorly ever since he has stomach ache and we both have nausea and diarrhoea. Can only put it down to this meal as we felt fine beforehand.
    Will not be having this again and possibly put me off gammon for life.

    1. Hi Nikki,

      I’m really sorry to hear you’ve been unwell.

      Food poisoning is usually a consequence of poor hygiene or cross-contamination during preparation, or not making sure food is piping hot before serving. We would never recommend that you cook meat on low in a slow cooker, and you’ll notice that these aren’t the instructions we provide.

      Please make sure your fridge is clean, under 8C and that you store raw meat properly. Hope you’re feeling better soon.

  2. Hmmm…not as delish as I thought but my slow cooker is a bit powerful and I only had 2 tins of beans which I added in an hour before the end. Ended up quite salty and watery- because of the beans. I added cornflour. Flavours good, ham lovely and tender- would be handy to know option for tinned beans! Thanks guys…love your site!

    1. Hi Hannah
      It sounds like there wasn’t anywhere near enough beans in there. As a rough guide half a cup of dried beans will give you about 1 and a half cups when they are cooked. Tinned beans will not expand. Beans are a very starchy food, so if there’s enough in there they will thicken up the stew quite a lot when you blitz the 2 ladles at the end of cooking

  3. Made this for tea today and it is lovely! The ultimate comfort food and so tasty. The kids even liked it too! Really easy to do as well, thank you! X
