Sausage and Lentil Casserole, Slow Cooker Style

Sausage and Lentil Casserole, Slow Cooker Style

I love lentils and beans, and happily – unlike a lot of my other favourite foods – they’re really healthy too. It was a chilly, wet autumn day and this combination seemed just right. Hence the invention of this easy sausage and lentil casserole, slow cooker style.

So I’ve tried to tick the kiddy boxes with this stew, which means a rich, Italian-style tomatoey sauce that’s also quite sweet. A little like her favourite tomato ketchup, which she is in love with. Any recipes based on that kind of flavour seem to go down a storm! Slow cooked lentils are soft and yielding, and thus more pleasing to the young palate. I have stated green lentils, but you could make a red lentil and sausage casserole or use Puy lentils or brown lentils if you like.

I’ve added some herbs, but to impart a subtle hint of flavour rather than an obvious hit. To make this lentil and sausage stew more child-friendly, I’ve not used garlic or pepper, but of course do feel free to add those if you prefer.

How do you make sausage casserole in the slow cooker? Well if your slow cooker pot can be used on the hob, then this is a one pot recipe. Otherwise use a frying pan or saucepan to cook the onion, carrot and sausages, then slice them up before slow cooking. Other than that, there is very little prep time involved in making this.

How to make sausage and lentil stew in the slow cooker

  • Heat a dash of olive oil in the slow cooker pot or a saucepan and add the onion, carrot and whole sausages. Fry on a medium heat, stirring often, for a few minutes until they start to brown.
  • Cut up the sausages. You can do this in the pan, but only if you’re careful and it isn’t the non-stick type. Otherwise, remove to slice before returning to the crock pot.
