The Best Slow-Cooker Sausage Casserole Recipe

I'm a 30-something mum of one living in South Wales and sharing recipes, travel posts, and craft guides.

Why Chose This Recipe?

Do you find you sometimes just don't have time to cook? Do you finish your working day and just want a nice hearty, filling meal? Do you own a slow cooker? (If not, you should!) Well, this recipe is perfect for you.

This is probably one of the simplest and most filling recipes I have cooked for a while in my slow cooker. Plus it's cheap, and although not super healthy, it is fairly good for you as it contains very little fat and plenty of healthy ingredients. It's also great for clearing out your fridge or cupboard as you can easily add a few other ingredients to it if you want.

So this is based loosely on a Poor Man's Cassoulet recipe I found in one of my old slow cooker recipe books, but I have added my own touches and altered it a bit for my own tastes. Believe me, this one will be a big hit with the whole family. The recipe feeds two but you can easily add more sausages and veg to make it enough for four.

2 servings


  • 4 sausages
  • 3 carrots, sliced
  • 1 yellow onion, diced
  • 1 tin kidney beans, drained and Rinsed
  • 1 teaspoon or 2 cloves chopped garlic
  • 4 slices smoked bacon, rindless and sliced
  • 300 ml beef stock (or other)
  • small tin sweet corn, drained


  1. Heat the garlic and onion in a pan with a little oil. Add the bacon and sausages to the pan and cook for a few minutes until sausages are just starting to brown.
  2. Put the carrots, kidney beans, and stock in the slow cooker and set to heat on low.
  3. Once the sausages have browned, add the mix to the slow cooker, cover, and leave it on low for 6-8 hours.
  4. 30 minutes before serving, add the tin of sweet corn and stir well. Replace the lid and let it cook for the 30 minutes.
  5. Serve over rice or with potatoes for a filling, hearty meal!

Variations on the Recipe

  • I added carrots as they happened to be the vegetable I had in the house at the time, you could just as easily add potatoes to the dish or any other root veg.
  • Kidney beans can be replaced with haricot beans, black-eyed beans, or any mixture of beans.
  • If you chopped up the sausage into chunks, this could be served as a thick stew with a nice piece of crusty bread instead.
  • This can also be made as a crock-pot freezer meal—just cook the meat and onions before placing it all in a freezer bag with the other ingredients and the stock and freeze. Pull out the night before and let thaw a little, then bung it in in the morning. Sorted!
