Recipe Difficulty – Very Easy

Why this recipe works

This Slow Cooker Sausage Casserole is just what I fancy during the colder months! It is super warming and filling and is perfect for when the weather is bleak outside and you fancy something comforting. 

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. 

If you don’t have a slow cooker or crock pot, 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

1. 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.
2. Black beans – these are a great plant-based protein and add the perfect texture for the meat free casserole.
3. Chickpeas – are also a great protein and pair really well with the black beans for the sausage and bean casserole.
4. Onion – I’ve used a white onion in this recipe, however you could use a red onion or yellow onion if you preferred.
5. Garlic – adding garlic offers a gentle spice and adds more flavour.
6. Vegetable stock – adds to the general flavour as well as adding body and depth to the recipe.
7. Sausages – I’ve used meat-free sausages, however if you aren’t vegan or veggie you could use meat sausages. See my section below about sausage recommendations. If you have any Sausage Pasta.
8. Red pepper – This adds some veggies and compliments the flavours. You could use a green or yellow pepper as a substitute. If you have any spare then make my Red Pepper & Tomato Soup.
9. Cumin – I love cumin! This is a rich and hearty spice and really enhances the flavour.
10. Paprika – this spice provides a round, woody, smokey flavour that really takes this veggie casserole to the next level!
11. Ground coriander – a fresh tasting spice, that is floral and citrusy.
12. 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, carrots or courgettes!
• Beans – Feel free to substitute the chickpeas or black beans to an alternative of your choice e.g. cannelloni beans or tin of butter beans. You could even create a Sausage and Baked Bean casserole if you wished!
• Stock – instead of vegetable stock you could opt for chicken stock or beef stock if you have this to hand.
• 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.
• Deluxe – If you are having dinner guests, this dish is the perfect hassle free recipe. You can simply forget about dinner whilst enjoying the company of your guests. For an extra umami hit you could add a few drops of worcestershire sauce or a squeeze of tomato puree to much a very rich tomato sauce.
• 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.

What Sausages to use in a casserole

This comes down to personal preference. I love making these with chicken sausages or meat-free sausages. If opting for pork sausages go for high meat content without too much other flavourings as they won’t need it.

Leftovers

This is a great recipe of meal prep! Store any cooled leftovers in an airtight container in your fridge for up to 3 days, or for up to 3 months in a freezer. You could also portion servings out into individual containers for meal-prep ahead of a busy week. If cooking from frozen, allow to defrost fully, before gently reheating on the hob or slow cooker until piping hot.
