Sausage, peppers, and onions is an iconic Italian-American food. There’s something so soothing about the hearty flavors in this classic dish. The meat is savory and juicy, the onions and bell peppers are sweet and cooked to the perfect tenderness, and the garlic and marinara sauce is irresistible. This crock pot sausage and peppers recipe has quickly become my go-to when I’m craving this filling and healthy dinner.

Cooking sausage and peppers in the slow cooker ensures that all the ingredients are tender, moist, and not overcooked. It also increases the intensity of the flavors and makes this dinner so easy to make. You’ve got to give it a try. 

Why You’ll Love This Slow Cooker Sausage and Peppers Recipe

I make this hearty comfort food all the time. Here’s why you need to try this crock pot sausage and peppers recipe.

  • Easy. Recipes don’t get much easier than this slow cooker sausage, peppers, and onions. All you have to do is put the ingredients in the slow cooker and turn it on. That’s it! 
  • Healthy. Sausage and peppers might taste like a treat, but it’s actually a very healthy food. I use chicken sausage when I make this recipe, so the dinner is just lean meat, vegetables, and tomato sauce. That’s pretty darn healthy. 
  • Versatile. One of the best things about Italian sausage and peppers is that you can eat it in so many different ways. You can serve this recipe as an entree or as a side dish. I like to add melty mozzarella cheese, and then use the crock pot sausage and peppers in a sandwich. You can also put this slow cooker recipe in a pasta dish, in a wrap, or even in an omelet. 
  • Large batch. The recipe I’m giving you is for 4 people, but you can easily double or triple it. Because the sausage and peppers are cooked in a crock pot, you don’t need to adjust the recipe or the timing if you scale it up. You can make as much of this recipe as will fit in your slow cooker.

Ingredients Needed 

You only need 6 ingredients to make this hearty and healthy classic comfort food. Make sure to check out the recipe card at the bottom of the page to see the exact amounts for each of the ingredients. 

  • Sausage links – I use Italian chicken sausage. 
  • Yellow bell pepper
  • Red bell pepper
  • Onion – A yellow onion is best for this recipe, but a red or white onion will also work.
  • Garlic
  • Marinara sauce 
  • Shredded mozzarella cheese – This is an optional ingredient. 

How to Make Crock Pot Sausage and Peppers

Here’s how to make this super easy sausage, onions, and peppers dinner. You’ll be shocked at how simple this recipe is! 

  • Cut the veggies. Thinly slice the bell peppers and onion, then place in the slow cooker. 
  • Add the seasonings. Put minced garlic in the crock pot, then pour the marinara sauce over the top. Stir to combine.
  • Put the sausage in. Add the Italian sausages on top of the pepper and sauce mixture.
  • Cook. Put a lid on the crock pot and cook on low for 3-4 hours, then serve.
  • Add optional cheese. If you want to add melted cheese, sprinkle the mozzarella over the top of the recipe when it’s done cooking. Put the lid back on, and let the cheese melt for 5 minutes. 

Tips, Tricks, and Variations

These are a few tricks and variations that you can use when making crock pot sausage and peppers.

  • Make consistent cuts. For best results, try to cut all of your peppers and your onion into similarly-sized pieces. The veggies will get tender regardless since you’re using a slow cooker, but the texture will be a lot better if all the veggies are the same size.
  • Mix and match. I used red bell pepper, yellow bell pepper, and Italian chicken sausage for this recipe, but feel free to mix it up. You can use whatever bell peppers you like best, and even add more of them if you want. You can also use pork sausage, or any flavor of sausage that you like.
  • Make it spicy. A lot of people like to add a kick of heat to their sausage and peppers. If that sounds good to you, you can add crushed chili flakes to the recipe, or cut up a fresh jalapeño, or any other type of hot pepper.
