This slow cooker sausage casserole recipe is one of my all-time favourites. There’s something SO comforting about a sausage casserole, especially when it’s able to slow cook and be ready for you once you get home!
Loved by the whole family, this sausage casserole is flavoured with thyme, paprika, tomatoes and garlic. A rich base of carrots, onion and peppers make the dish feel light, whilst being rich and comforting, too.
I love to serve this recipe with crusty bread and creamy mashed potatoes. You can freeze any leftovers you have, or keep them in the fridge for up to 2 days.
How to make sausage casserole in the slow cooker
Scroll down for full ingredient list and recipe card
1. Peel the carrot and onion. Then slice the carrot, onion and peppers into bite-sized pieces.
2. Add oil to a large, non-stick pan
3. Add in the onions and carrots
4. Cook until the onions begin to brown, about 5 minutes – stirring often
5. Then transfer to your slow cooker pan
6. To the same pan you cooked the onions and carrots in, add in the sausages. You want to brown the sausages on each side – which usually takes 2 mins a side. Make sure to brown them as much as you like as they won’t get any browner once transferred to the slow cooker.
7. Once browned, crush in the garlic gloves
8. Then add in the sugar, salt, thyme, paprika, tomato puree and chicken stock cube
9. Pour in the tinned tomatoes, and 100ml of water. 100ml of water is one quarter (1/4) of the tin, so I tend to just use the tin to measure this out
10. Stir all together
11. Then transfer to the slow cooker, and add in the earlier chopped peppers
12. Turn the slow cooker to high for 3 hours, or low for 6 – then serve!
