There are hundreds of ways you can serve this delicious dish. I will just go through just some of the ideas of what you could do.

Depending on what you feel like eating, you can eat these on top of some potato mash, rice or even zucchini pasta.

Sausage and Peppers

You can have this dish in a hot dog roll or something similar. To make it even better, add some Swiss or cheddar cheese to the bread roll.

A side dish such as scalloped potatoes is excellent if you rather eat the sausage and peppers without a bread roll or mashed potato.

Even though this is usually a lunch or dinner dish, you can easily have this as a breakfast. It will go pretty well with some hash browns, eggs, and some bacon.

Recipe Tips

  • To ensure that this recipe is gluten-free check the ingredients of the sausages.
  • For the best results, I highly recommend mixing up the type of bell peppers you’re using. This particular recipe I used a red and green bell pepper. Using a variety of different colored peppers gives you not only a great combination of colors but also flavor.
  • Browning of the sausages is completely optional, but I highly recommend doing it to reduce the amount of oil in the final dish. You will also find that it does help add a bit of a different texture to the sausages.
  • If you can’t get your hands on Italian sausages, then any kind of fat sausage will do. Just keep in mind the fattier the sausage is, the more fat will pool in the slow cooker. Simply just skim this off at the end of cooking.
  • For a little bit more flavor, you can add a splash of red wine to the sauce.
  • Other types of sausages will work fine in this recipe. For example, you can try using something like chorizo or kielbasa instead.

Note: I use a 5.5L (6 Quart) slow cooker (Amazon | Walmart) for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.

    Loved the deep rich flavors of the sauce. Think I was a bit cheap on the sausages as they didn’t turn out as well.
