Slow Cooker Sausage Casserole – French Style

This slow cooker sausage casserole takes inspiration from French food.

Slow cooker sausage casserole French style

This unashamedly British casserole takes inspiration from the French cassoulet – a haricot bean dish flavoured with sausages, poultry and often pork or bacon. Cassoulet has its origins in French peasant food – a way of flavouring beans when that’s all you can afford to feed your family. In a more modern British fashion, this casserole uses beans to pad out a pound of sausages so it feeds more people, or has some left for another meal.

In choosing vegetables I was influenced by the French mirepoix, a combination of onions, carrots and celery, roasted or sauteed to provide a flavour base for soups and stews. As I wanted a convenient slow cooker meal, however, I simply cut the vegetables into even chunks and slung them in. If you prefer rib celery to the root celeriac you can use that instead, but we are not fond of it.

The finished dish tasted nice and meaty, with a definite sweetness from the celeriac and carrots. It was aromatic, and filling without being too heavy. Definitely one to make again!

  • 1 lb pork sausages
  • 5 large carrots
  • 4 small onions
  • 1 celeriac root
  • 2 cans haricot beans
  • 1 can cannellini beans
  • 1 desert spoon each of stock powder, cornflour, garlic, dried tarragon
  • on at 10:50


  1. Slice the peel from the celeriac root and cut it into even sized chunks, a centimetre or two across.
  2. Peel and dice the carrots and onions. Place the vegetables in the slow cooker.
  3. Open the cans of beans and drain them. Add them to the slow cooker.
  4. Chop the sausages into chunks - 3 or 4 chunks per sausage - and add them to the slow cooker.
  5. Mix the seasoning ingredients together and add a little water to make them into a paste. Add this to the slow cooker, and mix well.
  6. Boil the kettle and add boiling water so it comes up to around an inch below the top of the food. Place the lid on, and cook on low for around 7 hours.
  7. If the sauce needs thickening, turn it up to high for a few minutes while you set the table.
