The casserole has a thick flavor packed gravy that is so good you will find yourself going back for seconds. It might not look like the tastiest dish, but this proves that looks can be very deceiving.

This dish can be eaten by itself but if you’re looking for something to go with it then I recommend a delicious creamy potato mash or even just some rice. My personal favourite is the potato mash!

If you have leftover sausages, then a good way to use them all up is in this sausage casserole. You will also be able to skip the first step since the sausages are probably already cooked. Simply slice and place in the slow cooker.

Recipe Tips

  • Supposing that you find the sauce is still really runny by the time you’re ready to eat it then you can thicken it up using a bit of cornflour. Simply mix 1 tbsp. cornstarch to 1 ½ Tbsp. of water and then mix this into your sauce. It should thicken up quite a bit. Repeat if you need to make it thicker.
  • If you’re a fan of beans and would like to bulk this out a little, then 400g (14 oz) cannellini beans is an excellent addition to this. Make sure you drain and rinse them before adding it to the slow cooker. Add these when you add the carrot.
  • In the case that you prefer the peas to be bright and green, then add these before you go to serve the casserole. Remember if you’re adding these frozen it will cool down the casserole so you will probably want to make sure it heats back up. Turning the slow cooker to high for fifteen minutes should be long enough to reheat it.
  • Assuming that you love bacon, then you can add some to this dish as well. Merely dice about four slices of bacon and cook off with the onion. This variation will add that amazing bacon flavor we all know and love.
