Slow Cooker Sausages in Onion Gravy

This slow cooker sausages in onion gravy recipe features a delicious homemade gravy that you can make just a few simple ingredients.

Slow Cooker Sausages and Onion Gravy

By the end of cooking, you will have some lovely juicy sausages and rich onion gravy. It’s an excellent combination that is likely to please all your friends and family. I do highly recommend cooking some sides to go with this dish.

You may be thinking that you can easily do this dish in a frypan in just a few minutes, but you will miss out on all the lovely slow-cooked flavors of this recipe.

This dish is yet another classic that goes excellent with some mashed sweet potato. You will have the classic bangers and mash dish. If you have two slow cookers, you can make the mashed potato in one and this sausage dish in another.

Other sides that go great with this recipe. For example, something like fried or oven baked chips go great on the side. Even something like cauliflower cheese will go great on the side.

Sausages and Onion Gravy with Peas and Mashed Potato

The sausage that you use is entirely up to you. I made use of some Italian beef sausages, but smoked sausage such as Kielbasa or chorizo will work nicely as well.

You should find that this recipe will feed roughly four to six people, but this will depend on how many sides you make. You can easily double or triple the recipe to feed more people.

Any leftovers are worth keeping as they will reheat the next day nicely. Heat in the microwave or frypan for the best results.

I have spent a bit of time and put together a video that goes through the steps making this delicious sausage meal. You can find the video right below, otherwise there is a written recipe right underneath it.

Recipe Tips

  • You can use a gravy powder instead of our homemade gravy. Use ¼ cup of gravy powder and use water instead of chicken stock. You will no longer need the cornstarch mixture. Add the gravy powder at the start of cooking.
  • Add some mushrooms if you want an onion and mushroom gravy. Simply add these at the start along with the onion. The result will be just as delicious, if not better.
  • I highly recommend that you brown the sausages before adding them to the slow cooker. It helps reduce the amount of fat produced while slow cooking and will help the sausage keep a nicer texture. With that said, if you're low on time, you can skip this step.
  • To get a deep brown color to your gravy, you can use a drop or two of Parisian essence. This ingredient is readily available in Australia but might be harder to come by in other countries.
  • If you love gravy, then you can always add extra vegetables. Carrots will cook nicely if you add them at the start. If you want peas, then add these at the end, so they don't discolor.
