This Slow Cooker Italian Sausage & Peppers recipe is an easy family dinner that requires very little hands-on preparation.
The slow cooker does most of the work for you. Simply slice the vegetables, add everything to the crockpot, season it well, and let the gentle heat bring all those delicious flavors together.

🛒 Ingredients
For the Sausage & Peppers
- 5–6 Italian sausage links, mild or hot
- 1 yellow bell pepper, sliced
- 1 green bell pepper, sliced
- 2 red bell peppers, sliced
- 1 large yellow onion, sliced
- 3 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes
- 1 cup tomato sauce or tomato liquid
- 1 teaspoon Italian seasoning
- ½ teaspoon garlic powder
- ½ teaspoon black pepper
- Salt, to taste
For Serving
- 4–6 hoagie rolls
- Mozzarella or provolone cheese
- Fresh parsley, optional
- Extra Italian seasoning, optional
- Grated Parmesan, optional
👩🍳 Instructions
Step 1: Prepare the Vegetables
Start by washing and slicing all of your bell peppers. Remove the seeds and cut the peppers into strips.
Slice the onion and mince the garlic.
Try to keep the pepper and onion slices relatively similar in size so they cook evenly.
Step 2: Build the Slow Cooker
Place the sliced yellow, green, and red bell peppers into the bottom of your slow cooker.
Add the sliced onion and minced garlic.
Pour in the diced tomatoes and tomato sauce.
Give the vegetables a gentle stir to distribute the ingredients.
Step 3: Add the Sausage
Place the Italian sausage links directly on top of the vegetables.
Sprinkle the sausage and vegetables with:
- Italian seasoning
- Garlic powder
- Black pepper
- A little salt
The sausage will release flavorful juices as it cooks, helping create an incredibly tasty tomato and pepper mixture.
Step 4: Slow Cook
Cover the slow cooker with the lid.
Cook on:
LOW: 6–7 hours
HIGH: 3–4 hours
Cook until the sausage is fully cooked through and the peppers and onions are tender.
Cooking times can vary depending on the size of the sausage links and your slow cooker, so check that the sausage has reached a safe internal temperature before serving.
🍅 Slow Cooker Method
The beauty of this recipe is how simple the method is.
As the sausage slowly cooks, its savory juices mingle with the tomatoes, peppers, onions, and garlic. The peppers become soft and sweet, while the onions develop a rich flavor.
The tomato sauce creates a delicious base that can be spooned generously over the sausage when serving.
For an even richer flavor, you can brown the sausage in a skillet before adding it to the slow cooker. This isn’t required, but it can add extra color and a deeper roasted flavor.
🥖 How to Make the Italian Sausage Sandwiches
When the sausage and peppers are ready, it’s time to make the sandwiches!
1. Toast the Rolls
Cut the hoagie rolls open without completely separating them.
Place them under the broiler or in a toaster oven for a few minutes until lightly golden and crisp.
2. Add the Sausage
Place one sausage link inside each toasted roll.
3. Add the Peppers & Onions
Spoon plenty of the tender peppers, onions, and tomatoes over the sausage.
Don’t forget the delicious tomato juices!
4. Add Cheese
Top each sandwich with mozzarella or provolone cheese.
Place the sandwiches under the broiler for a minute or two until the cheese is melted and bubbly.
5. Finish & Serve
Sprinkle with a little Italian seasoning, fresh parsley, or Parmesan cheese if desired.
Serve immediately while hot. 🤤🧀

Cheesy Sausage & Peppers

💡 Helpful Cooking Tips
Don’t overcrowd the slow cooker. Arrange the sausage and vegetables so everything has room to cook properly.
Use colorful peppers. Red, yellow, and green peppers create a beautiful dish with slightly different flavors.
Don’t throw away the sauce. The tomato-pepper juices are one of the best parts of the recipe!
Toast the bread. A crispy hoagie roll provides a wonderful contrast to the tender sausage and vegetables.
Melt the cheese at the end. Adding the cheese just before serving keeps it beautifully melted and gooey.
Let the sausage rest briefly. Allowing it to sit for a few minutes before serving helps keep it juicy.
📖 A Little History
Sausage and peppers is closely associated with Italian-American cooking and has become a beloved comfort-food combination in the United States.
Italian immigrants brought sausage-making traditions and familiar Mediterranean ingredients with them, while American cooks adapted those traditions using locally available peppers, onions, tomatoes, and bread.
Over time, sausage and peppers became especially popular at Italian-American festivals, street fairs, family gatherings, and casual neighborhood dinners.
The combination works so well because the savory sausage pairs beautifully with the sweetness of cooked peppers and onions, while tomatoes add acidity and richness.
Today, sausage and peppers can be prepared in many ways—from a skillet meal to a baked casserole or a slow-cooker dinner like this one.
