Ingredients

There’s a full recipe card below with the quantities and instructions. But here are the main ingredients for this easy slow cooker sausage casserole.

• 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.
• Baked Beans: 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: Canned tomatoes are easy to find and a great cheap ingredient.
• Bacon Lardons: Essential for that smoky flavour – or use chopped streaky bacon.
• 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.
• 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.
• Spices and Aromatics: I also use smoked paprika, red onion and garlic to flavour this gluten free sausage and beans casserole.

How to make slow cooker sausage and bean casserole

Making this slow cooker sausage and bean casserole in the slow cooker honestly could not be any easier! But here are some step-by-step photos to guide you.

I like to fry off the bacon before adding it to the slow cooker 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. I find it also deepens the flavour of the casserole!

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.

How to make Sausage Casserole in the oven

If you don’t have a slow cooker you can make this gluten free baked bean and 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!

Storing and Freezing

Can you reheat sausage casserole leftovers? Of course you can! Any leftovers can be kept in the fridge for up to 3 days and reheated thoroughly before eating.

You can also portion this casserole up and freeze it for up to 6 months. I recommend labelling it when freezing!

Then simply defrost and reheat, or even reheat thoroughly from frozen, before eating.
