Slow Cooker Sausage and Peppers
Slow Cooker Sausage and Peppers is so easy for a one-dish meal, and if you like these ingredients you’ll make this often. And I think cooking sausage and peppers with marinara sauce in the slow cooker adds amazing flavor.
PIN Slow Cooker Sausage and Peppers to try it later!
Slow Cooker Sausage and Peppers is an easy meal inspired by something I used to make in the very early days of my blog! This was when I was a full-time teacher struggling to keep up with the blog. I used to love simply browning Italian Sausage links and throwing them in the slow cooker with 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 a salad.
Recently the idea popped into my head to turn that simple dish into an actual recipe. And sausage and peppers cooked in the slow cooker combines two of my absolute favorite ingredients! I found this easy way to cook them so satisfying that I found myself making it several more times within a few weeks!
And I experimented with making this 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 think slow cookers are having a bit of a comeback in this era of rising food prices, and they’re a great way to make simple inexpensive ingredients taste amazing! If you’re someone who still pulls out the slow cooker once in a while I hope you’ll give Slow Cooker Sausage and Peppers 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 near me. Now I’m a fan of Denmark Foods All Natural Hot Italian Sausage. I buy this in a pack of ten sausages at Kroger, and it only has one net carb per sausage. I use half the package in 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 make this recipe with the 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!

Slow Cooker Sausage and Peppers
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 enjoy this as a low-carb one-dish meal with some Parmesan cheese sprinkled on top!
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
- 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.
- Remove sausage to cutting board and cut each sausage in half lengthwise.
- Heat the rest of the olive oil, add sausage, and brown the cut side of the sausage.
- 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.
- 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.
- While sauce reduces, cut red and green peppers into pieces a little bigger than one inch across.
- 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.
- 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.
- That's it for this easy recipe; enjoy!
- 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.

Glad to hear you are enjoying the recipes. Thanks for letting me know.
I just wanted to drop you a line. I'm new to south beach. I love to cook and your collection of recipes and beautiful pictures are keeping me cooking, healthy and happy. Thanks for everything!
That does sound good with the picante sauce! Glad you are enjoying the recipes.
I have this recipe bookmarked! I changed it up one day. I browned the sausage with olive and onion. Once they were brown, I poured a small jar of Pace pecante sauce over them and let them simmer slowly for about an hour. My husband LOVED it. I used mild sausage and medium pecante sauce (he's not much of a spicy person). But it turned out perfect.
Thanks for all your wonderful recipes!
Thank you for this recipe! We had it the other night and it was super delish!
Kalyn,
I have never been a fan of sausage, but your pic looks inviting. 🙂
Coffeepot, I think I actually prefer the turkey Italian Sausage to the pork ones! Welcome back.
Sher, they are one of my absolute staples.
Meeta, in the oven on low would be fine, or even simmer on the stove on low for an hour or so.
Kalyn, wow! We love sausages here and living in Germany we get so many different varieties. This is an amazing, simple and delicious sounding recipe. I do not have a crockpot but I assume I can do it in the oven at a low temp – right?
Oh boy, come to mama!!! Easy AND delicious. That’s perfect!
Hey Kalyn,
I just had some turkey italian sausage tonight before I read this.
I do like it lower fat and with great taste too.
I have been away too long already and missing all those great ideas of yours.
How fun to get so many nice comments on such a simple recipe. Sometimes simple food is the best. I like everyone’s ideas for variations too.
Brady, glad tohear you liked the Dreamfields pasta, and good luck with the new baby that’s coming.
Hey ya know, that reminds me of a recipe my uncle received from a neighbor years ago. I think it would fit in with these diets ya’ll are talking about too.
Saute slices or hunks of zucchini, hot quick, no completely cook. Add tomato sauce, plain or otherwise. Add crumbled bacon and simmer until done. Serve.
Thanks for the memories!
Yet another great reason to buy that crock pot I’ve been thinking about….
This looks great!
mmm..be great with some onions and peppers 😉
Kalyn-
This has nothing to do with today’s yummy post, but I just wanted to thank you. Last night I made a big pot of what our family calls goulash (ground beef, onions, garlic, stewed tomatoes, some italian seasoning, pasta and corn). Not goulash at all, but I think every family has some version of this. Any how I used the Dreamfield’s pasta for the first time because of your suggestions and we loved it. As you know, we are not South Beachers, but we try to eat healthy. Soon I will have copious amounts of baby weight to lose so I wanted to thank you for all of your wonderful and healthy recipes.
Happy Holidays-
Brady
Kalyn, the first photo looks deliciously incredible! We eat plenty of sausages so this really caught my eyes.
These would be great sliced up and eaten with penne pasta…
