How to make this Slow Cooker Italian Sausage and Peppers:

You have two ways to make this recipe. One is using a cast iron skillet and slow cooker and the other way is using only a slow cooker (throw everything in the slow cooker and let it cook by itself). However, if you want my honest opinion, I think the first option is better because the sausages will have a nice crust that you get from sautéing them in the cast iron. This is how I make this Slow Cooker Italian Sausage and Peppers:

  • In a skillet, heat olive oil over medium-high heat. When the skillet is very hot, add sausage links, and cook for about 2 minutes each side. This step is very important to give the sausages a nice crust. Then, place them on a cutting board, slice them and place in the slow cooker.
  • In the same skillet, add onions and cook for about 2 minutes. If you need pour more olive oil and stir constantly. Then add garlic and cook for 30 seconds. Transfer onions and garlic to the slow cooker.
  • Again in the same skillet add mushroom and cook for 2 minutes or until they get a nice golden color. Transfer to the slow cooker.
  • Now in the slow cooker, add bell pepper, tomato sauce, salt and black pepper. Cover and cook for 5 hours on low or 3 hours on high, or until sausages are cooked through and tender.  Top with parsley before serving.

Can sausage and peppers be frozen?

Yes, absolutely! Sausage and peppers freeze very well. Store leftovers in the refrigerator for up to 4 days or freeze for up to 3 months. It’s even more delicious on the second day. Let thaw overnight in the refrigerator and reheat gently on the stove before serving.

How long do sausages take to cook in slow cooker on high?

It will take about 2-3 hours on high and 5-6 hours on low.

Do you have to cook sausages before putting in slow cooker?

No it’s not necessary, but I think if you sauté the sausage in the skillet before putting in the slow cooker, it will add an extra flavour to this dish and the sausage will look delicious.

Can I use pre-cooked sausage to this recipe?

No, I really don’t think it’s a good idea. The best sausage to make this Slow Cooker Italian Sausage and Peppers recipe is the uncooked Italian sausage in its casing and you can use either sweet Italian sausage or hot Italian sausage recipes. It’s totally up to you.
