Recipe Difficulty – Very Easy

Although we seem to be heading into Spring shortly (fingers crossed!), the days still seem to be pretty chilly at the moment and I’m definitely not in the mood for cold salads come lunch time or dinner time yet. This Slow Cooker Sausage Casserole is just what I fancy! It is super warming and filling and is perfect for when the weather is bleak outside and you fancy something comforting. For more comforting slow cooker recipes, definitely also check out my Slow Cooker Carrot and Coriander Soup or my Slow Cooker Vegan Chilli – both of these are bursting with flavour and require minimal prep!

I’m a huge fan of slow cooker recipes at the moment (especially when they are bursting with flavour!). They’re a great win for when time is limited, but you want something wholesome, nutritious and filling. As you can imagine, time isn’t really on my side at the moment with my 4 month old daughter, so I’ve been using my slow cooker more and more recently! Thus this amazing veggie Slow Cooker Sausage Casserole was born! Served with some quick and easy Chickpea Flat Bread to really mop up the sauce, you’ve got a seriously hearty meal on your hands which took no effort at all!

If you don’t have a slow cooker, don’t worry you can still make this recipe on the hob. For further instructions on how to make this recipe without a slow cooker, see the FAQ’s section further below on this page.

Ingredients to make Slow Cooker Sausage Casserole

  • Chopped tomatoes – these provide a great base for the Slow Cooker Sausage Casserole, they provide an acidity which adds depth of flavour and also adds the perfect amount of liquid for the casserole
  • Black beans – these are a great plant-based protein and add the perfect texture for the meat free casserole
  • Chickpeas – are also a great protein and pair really well with the black beans for the sausage and bean casserole.
  • Onion – I’ve used a white onion in this recipe, however you could use a red onion if you preferred
  • Garlic – adding garlic offers a gentle spice and adds more flavour
  • Vegetable stock – adds to the general flavour as well as adding body and depth to the recipe
  • Sausages – I’ve used veggie sausages to keep make this a vegetarian casserole, however if you aren’t vegan or veggies you could use meat sausages
  • Red pepper – This adds some veggies and compliments the flavours. You could use a green or yellow pepper as a substitute
  • Cumin – I love cumin! This is a rich and hearty spice and really enhances the flavour
  • Paprika – this spice provides a round, woody, smokey flavour that really takes this veggie casserole to the next level!
  • Ground coriander – a fresh tasting spice, that is floral and citrusy
  • Chilli powder – this adds a subtly heat to the Slow Cooker Sausage Casserole, but don’t worry it isn’t too overbearing!

Substitutions

  • Pepper – I’ve used a red pepper in this sausage casserole with vegetables, however a green or yellow pepper would also work. You could also add in any other vegetables that need using up, sometimes I add mushrooms or courgettes!
  • Beans – Feel free to substitute the chickpeas or black beans to an alternative of your choice e.g. cannelloni beans. You could even create a Sausage and Baked Bean casserole if you wished!
  • Sausages – I’ve used vegetarian sausages in this recipe to keep it meat free. However, you could use meat sausages if you preferred.
  • Spices – if you don’t have access to all of the spices, don’t worry too much, the flavours would still be there from the stock and other remaining ingredients! However, with all the spices in tow, they really do take the veggie casserole to the next level!

Variations

  • Spicy – This is a mild recipe so that everyone can enjoy it. If you are cooking for someone who is particularly sensitive to spice, feel free to remove the chilli powder. Equally if you wanted to up the heat in this Slow Cooker Sausage Casserole then you can increase this quantity of chilli powder or add some cayenne pepper. You could even add some freshly chopped chillis on top of the veggie casserole. If you like spice then definitely check out my Warming Pasta, it’s so simple to make and has a lovely heat running through it.
  • Deluxe – If you are having dinner guests, this is the perfect hassle free recipe. You can simply forget about dinner whilst enjoying the company of your guests. If you wanted to take this veggie sausage casserole to the next level you could serve it with some Herb Salted Hassel Back Potatoes. Honestly, these Slow Cooker Sausage and Potatoes will totally impress your guests! You could serve it with some brown rice or quinoa and top it with some freshly chopped parsley. For dessert, you could also make my super quick and easy Vegan Rocky Road, which again requires minimal prep… win win!
  • Kid friendly – This is a great recipe to get the children involved in. It is simple and easy for them to follow and they’ll love checking on the slow cooker whilst it’s simmering away. If you wanted to get more creative with kids, I have a great Homemade Sweet Potato Gnocchi recipe which is really fun to do with them. Alternatively, you can’t go wrong with my 5 Ingredient Chocolate Flapjacks!
