This isn’t my first foray into making snags in the slow cooker, first there was the Slow Cooker Curried Sausages and then there was this Slow Cooker Sausage and Bean Hotpot  and now this warming casserole.

I think what I love most about this recipe is that it’s so versatile. You can use any sausages you like but I find that it’s good quality, thick sausages work best. You can also take liberties with the veg, use whatever you have to hand.

The serving possibilities are also almost endless, we like it best with mash but it also goes great with baked potatoes or crusty bread to mop up all those delicious juices!

How to

  1. Heat the oil in a large pan and fry the onion and garlic over a low heat for about 5 minutes or until softened.
  2. Spoon the onion mixture into the slow cooker. Add the carrots to the pan and fry for a couple of minutes. Add to the slow cooker.
  3. Brown the sausages in the same pan, ensuring they get a good colour all over because they won’t brown in the slow cooker.
  4. When the sausages are well browned, add to the slow cooker along with the sweet potato, pumpkin and the tinned tomatoes. 
  5. Add the tomato paste to the pan along with 1 cup (250ml) boiling water, swirl around to get all the flavour and add to the slow cooker.
  6. Add the herbs and stock pot and season with pepper. Don’t add any salt because the stock cube/pot usually have a high salt content.
  7. Cook for 4 hour on HIGH or for 8 hours on LOW.
