There’s a full recipe card below with the quantities and instructions, but here are the main ingredients and ideas for any substitutions:

Gluten Free Sausages: Most supermarket sausages tend to be gluten free in the UK, but not all of them. Always double check to make sure the sausages you’re using are safe.

I love Lincolnshire sausages in this recipe but something like a chorizo sausage or a caramelised onion one would be a great twist. The Sainsbury’s Taste The Difference ones are my go-to but Tesco, Lidl, Asda, Aldi, Morrisons and brands like Heck all have plenty of gluten free sausages to choose from.

Baked Beans: As far as I’m aware, most baked beans are gluten free but always double check. I just used cheap, own-brand supermarket baked beans but you can use Heinz if you like!

Tinned Tomatoes: This helps to bulk out the casserole and give it a nice flavour. I do love using tinned tomatoes because they’re so cheap and easy to find.

Bacon Lardons: These are essential for getting a lovely smoky, salty flavour in this gluten free sausage casserole.

Red Pepper: I always like to add extra veg to a dish where I can and red peppers work so well with the tomato flavours of this casserole. You can use any colour pepper you like or omit them completely if you prefer.

Vegetable Boullion: I use this boullion a lot in my recipes as it’s completely gluten free. You could crumble in half a gluten free vegetable stock cube if you prefer, but I find the gluten free stock cubes don’t tend to crumble too easily.

Gluten Free Worcestershire Sauce: I use the Tesco Free From Worcestershire Sauce but I believe Henderson’s Relish is also gluten free.

Dijon Mustard: Most dijon mustard is gluten free but always double check. English mustard usually contains wheat flour so make sure you avoid this.

I also use smoked paprika, red onion and garlic to flavour this gluten free sausage and beans casserole.

How to make gluten free sausage casserole

Making this gluten free sausage casserole in the slow cooker honestly could not be any easier!

I like to fry off the bacon before adding it as it makes it nice and crispy, so you may as well brown the sausages at the same time.

It’s not necessary to do this but they won’t brown in the slow cooker so I think it adds a bit of colour.

Then it’s simply a case of chucking everything in the slow cooker together and letting it work it’s magic.

You can shove it all in before work and then come home to the most amazing-smelling sausage and bean casserole ever.

Which slow cooker do you use?

I use a Crockpot 3.7-litre slow cooker I was gifted from a family member – I think this is the newer model of mine.

I’m addicted to making things in the slow cooker at the moment, including my chickpea and potato curry and my slow cooker pulled pork.

I know a lot of people are worried about the cost of living and looking for cheaper alternative to turning on the gas or electric oven.

The good news is slow cookers are actually pretty efficient to run!

I’ve done a bit of research online and it looks like a slow cooker costs roughly 16p a day to run, compared to 87p a day for an electric cooker.

What if I don’t have a slow cooker?

If you don’t have a slow cooker you can make this gluten free sausage casserole in the oven or on the hob.

To do this, cook the sausages and bacon as per step 1 in the recipe, then add them back into a lidded casserole dish with all the other ingredients.

Preheat the oven to 180C / Gas Mark 4 and then place the dish, with the lid firmly on, in the oven for an hour.

Or cook it on the hob for around 40 minutes until the sausages are cooked through.

But ultimately this recipe is made for the slow cooker so I’d definitely recommend it as the best and most efficient way to make it!
