Slow Cooker Sausage and Peppers

Slow Cooker Sausage and Peppers is so easy for a slow cooker main dish, and if you like sausage and peppers you’ll want to make this often. I love this for a tasty one-dish meal with about 10 net carbs, but add zucchini noodles, a salad, or pasta if you prefer.

PIN Slow Cooker Sausage and Peppers to try it later!

Back when I was a full-time elementary school teacher struggling to keep up with this blog, I had a favorite dish I’d make for Weekend Food Prep by simply browning Italian Sausage links and throwing them in the slow cooker with a jar of low-sugar marinara sauce to cook for a couple of hours. Then I’d take one of the sausages to school to eat for lunch with some kind of side salad or zucchini noodles.

Recently the idea popped into my head to turn that super simple dish into more of an actual recipe! And this new recipe for Slow Cooker Sausage and Peppers is still extra easy to make and only has five ingredients. And it’s also something that’s great to make on the weekend and eat leftovers during the week.

I found this easy combination so satisfying that after I tried it once I found myself making it several more times within a few weeks, and I absolutely loved it for a low-carb main dish with my favorite Italian flavors. And I experimented with it enough times to come up with a tip for an easier way to brown the sausage on all sides, which is essential for getting the best flavor.

I do think slow cookers are having a bit of a comeback in this era of rising food prices, and they can be a wonderful way to make simple inexpensive ingredients taste great! If you’re someone who still pulls out the slow cooker once in a while I hope you’ll give this a try!

What Sausage did I use for Slow Cooker Sausage and Peppers?

For many years I always used Jenni-O Turkey Italian Sausage when I cooked Italian Sausage, but then it disappeared from the stores by me, and I was mourning it for a long time! Now I’m a fan of Demark Foods All Natural Hot Italian Sausage, which comes in a pack of ten sausages at Kroger, and only has one net carb per sausage. I use half the package for this recipe and freeze the other half to make it again later. You can use any brand of pork, turkey, or chicken sausage that you prefer, and either hot or sweet Italian sausage will be good.

What pasta sauce did I use for Slow Cooker Sausage and Peppers?

I’d love to use my own marinara sauce if I had some in the freezer, but most often I make this with the Rao’s Pasta Sauce (affiliate link) I’m so fond of. And all the Rao’s sauce varieties are super low in carbs! If you can’t find Rao’s where you shop, look at the nutritional information and pick the sauce with the lowest amount of sugar you can find!

I’d enjoy this recipe just served in a bowl as an easy one-dish meal. If you want something more, this would be amazing served with Zucchini Noodles. Or serve with something like Lemon Parmesan Kale Salad or Spring Mix Salad for an easy dinner!

Slow Cooker Sausage and Peppers

Prep Time 30 minutes

Cook Time 1 hour 30 minutes

Total Time 2 hours

Slow Cooker Sausage and Peppers is about as easy as it gets for a five ingredient slow cooker main dish, and this is delicious! I usually eat this as a one-dish meal with some Parmesan cheese sprinkled on top, but add some zucchini noodles or pasta if you like.

Ingredients

• 5 links Italian Sausage (see notes)
• 2 T olive oil
• one 24 oz. jar Rao's Marinara Sauce (see notes)
• 2 large red bell peppers
• 1 large green bell pepper

Instructions

1. Heat half the olive oil in a non-stick frying pan over medium-high heat, add sausages, and cook until they're nicely browned on both sides. They won't be cooked through.
2. Remove sausage to cutting board and cut each sausage in half lengthwise.
3. Heat the rest of the olive oil, add sausage, and brown the cut side of the sausage.
4. Put sausage on cutting board and cut into pieces when it's cool enough to handle. Put sausage pieces in slow cooker and turn to LOW.
5. Add the pasta sauce to the frying pan and simmer about 10 minutes so sauce is slightly reduced. Use the turner to scrape any sausage bits off the bottom of the pan.
6. While sauce reduces, cut red and green peppers into pieces a little bigger than one inch across.
7. Add peppers to slow cooker.When sauce has reduced by about 1/4 pour over sausage and peppers in the slow cooker and stir to combine.
8. Put lid on the slow cooker and cook on LOW about 1 1/2 hours for peppers that are still slightly crisp, or a bit longer if you prefer softer peppers.
9. That's it for this easy recipe; enjoy!
10. This will keep on the fridge for at least a week. It can also be frozen, although the peppers will soften when they're frozen. And I bet you won't have any left to freeze anyway!

Notes

Use pork, turkey, or chicken sausage, whichever you prefer. Either sweet or hot Italian Sausage will be delicious prepared this way. I used Denmark Foods All Natural Italian Sausage (from Kroger) with only 1 net carb per sausage.

I always use Rao's Pasta Sauce (affiliate link) for this recipe, and that's the lowest-carb sauce I have found. If your store doesn't have Rao's look for a sauce that's low in sugar.

Historical Notes for this Recipe:

I first started cooking Italian Sausage in the slow cooker with low-sugar marinara sauce back in 2006, when I was a full-time teacher who needed easy recipes to take for lunch to school. In 2023 that recipe was updated into this version that combined it into Slow Cooker Sausage and Peppers for a one-dish meal.
