Slow Cooker Sausage Casserole 

Slow Cooker Sausage Casserole 

Now autumn is here I love to be able to use the slow cooker to make my family warming and nutritious slow cooked meals, packed with vegetables. I may occasionally wax lyrical about the convenience of throwing your ingredients in the pot in the morning and coming back after a day at work (or play) to a cooked meal. You just can’t beat it! This slow cooker sausage casserole is the perfect way to use up any vegetables lurking in the bottom of the fridge too.

Slow Cooker Sausage Casserole 


I make the basic slow cooker sausage casserole quite often for my family, as it is one of the children’s favourites, adapting it to whatever vegetables I have on hand, and sometimes adding a tin of cannellini beans or a handful of red lentils. We tend to serve it with pasta or rice as my two aren’t big fans of mash. It always goes down well and warms us up on a damp chilly day.

We love the rich tomato-based gravy that you get after the long slow cook. Dipping a bit of bread in there to soak it all up when your plate is clear is one of the best bits! And using up all those veggies in this comforting and warming dish is just ideal. It is great to come home to a dish like this which has been left cooking all day while you are out, especially in colder weather.

  • sausages (preferably good quality this will prevent them from disintegrating the slow cooker during the long cooking time)
  • 2 red onions chopped
  • 1 yellow pepper chopped
  • 0.5 of large sweet potato chopped
  • 400 g tin chopped tomatoes
  • 1 tbsp tomato purée
  • 250 ml boiling water
  • 1 rich beef stockpot
  • 1 tsp dried rosemary
  • 2 tsp dried oregano
  • Cornflour to thicken if needed
  1. Brown the sausages on all sides over high heat in a dry pan. Place them in the slow cooker.
  2. Add the remaining ingredients, mix and cook on high for 4-5 hours or on low for 8 hours.
  3. An hour before serving, check if the sauce is thick enough. If not, make a paste using 1 tbsp cornflour and a little water, then stir the paste into the pot and let it cook for the last hour, to thicken.

I am so excited to start using my slow cooker again. I love the addition of sweet potato in your recipe. I love finding ways to add sweet potatoes to any recipe.


You are the slow cooker queen! I love the idea of this. Only really use my slow cooker for slow cooking meat but a casserole needs to be done. Looks so simple but yummy xx

I made this over the weekend and it was a winner with my DH who isnt much of a sausage casserole fan. He liked that it had sweet potato instead of regular. Trying the slow cooked lighter lasagne today!


Made this tonight, I used cannelloni beans & red lentils as suggested and served with mash & broccoli. Love that you don’t have to do much cooking before putting everything in slow cooker! Quick, easy & delicious! My 2 young daughters even ate it – finally a meal I can cook that the whole family will eat! Look forward to trying some more of your recipes!!
