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. This 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.


Serves 3-4 (you may need more sausages if cooking for older children than me).

  • 6 sausages (preferably good quality, this will prevent them from disintegrating in the slow cooker during the long cooking time)
  • 2 red onions, chopped
  • 1 yellow pepper, chopped
  • Half a large sweet potato, chopped
  • 400 g tin of chopped tomatoes
  • 1 tbsp tomato purée
  • 250 ml boiling water
  • 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.Slow Cooker Sausage Casserole 
  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.

  1. 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

      1. In Canada.
        I searched and found Knorr Beef Stock Pot – a concentrated beef stock in the UK. Not really / readily available here or the US. In Canada (but not the US) Unilever / Knorr sells Homestyle Stock Bouillon (a broth) which looks similar (and very high in sodium) and I have not seen in stores, though I will now look. Bouillon cubes – dehydrayed bouillon (Canada & US) / Stock cubes (UK) might be able to be made to work …
