How to Make Slow Cooker Sausage and Peppers
Step 1: Brown the Sausages
Heat olive oil in a large skillet over medium-high heat. Add the sausage links and cook for about 2 minutes per side, just until they develop a nice brown color. They don’t need to be cooked through as they’ll finish in the slow cooker.
Step 2: Prepare the Vegetables
While the sausages are browning, add the sliced bell peppers, onions, minced garlic, Italian seasoning, salt, and pepper to your slow cooker. Toss everything together until the vegetables are evenly coated with the seasonings.
Step 3: Assemble in the Slow Cooker
Pour the marinara sauce evenly over the seasoned vegetables. Once the sausages are browned, place them on top of the vegetable mixture in the slow cooker.
Step 4: Slow Cook to Perfection
Cover and cook on Low for 4-5 hours or on High for 2-3 hours. The sausages should be completely cooked through, and the vegetables should be tender but not mushy.
Step 5: Serve and Enjoy
Remove the sausages and vegetables from the slow cooker and serve with your preferred sides. Spoon the sauce generously over everything.
Pro Tips for Making the Recipe
- Brown the sausages first: This extra step is worth the flavor development, but if you’re in a rush, you can skip it and add 30 minutes to the cooking time.
- Cut vegetables uniformly: Slice the peppers and onions to similar sizes so they cook evenly.
- Don’t overcook: While slow cooking is forgiving, vegetables can become too soft if cooked too long. If you need to extend cooking time, use the “warm” setting.
- Layer properly: Placing the sausages on top of the vegetables allows them to steam rather than boil, giving them a better texture.
- Use fresh ingredients: Fresh bell peppers and onions will hold their shape better than frozen ones.

Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for 3-4 days. The flavors actually improve after a day as they continue to meld together.
Freezing
This dish freezes beautifully! Cool completely, then transfer to freezer-safe containers or bags. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently in a covered skillet over medium-low heat until warmed through. You can also microwave in 1-minute intervals, stirring between each, until heated to your liking. For larger portions, reheat in the oven at 325°F in a covered dish with a splash of water to maintain moisture.
FAQs
Can I use frozen peppers and onions in this recipe?
Yes, you can use frozen peppers and onions, but be aware that they’ll release more liquid during cooking. To compensate, reduce the marinara sauce by about 1/4 cup. The texture of frozen vegetables will also be softer in the final dish, but the flavor will still be delicious.
What’s the best way to prevent the vegetables from getting too mushy?
For firmer vegetables, cook on Low rather than High setting. You can also add the peppers halfway through the cooking time if you prefer them to have more texture. Another trick is to slice the vegetables slightly thicker than you might normally.
Can I add potatoes to this recipe?
Absolutely! Small baby potatoes or quartered red potatoes make a wonderful addition. Place them at the bottom of the slow cooker since they take longer to cook than peppers and onions. You might need to add an extra 30 minutes to the cooking time.
Is it necessary to brown the sausages before adding them to the slow cooker?
While not strictly necessary, browning the sausages adds significant flavor through the Maillard reaction and gives them a better texture. If you’re short on time, you can skip this step, but the final dish won’t have quite the same depth of flavor.
This Slow Cooker Sausage and Peppers recipe transforms simple ingredients into an incredibly satisfying meal with minimal effort. The combination of tender sausages, sweet peppers and onions, and savory marinara creates a classic Italian-American dish that’s sure to become a regular in your meal rotation.

Ingredients
- 1 tbsp olive oil

- 6 cloves garlic (minced)
- 1 tbsp Italian seasoning
- 1/2 tsp sea salt
- 1/4 tsp black pepper
- 1 1/2 cups marinara sauce
Instructions
- Brown the Sausages: Heat olive oil in a large skillet over medium-high heat. Once hot, add the sausage links and cook for about 2 minutes per side, just until browned on the outside. Don’t worry about cooking them through as they’ll finish cooking in the slow cooker.
- Prepare the Vegetable Base: While the sausages are browning, combine the sliced bell peppers, onions, minced garlic, Italian seasoning, salt, and black pepper in your slow cooker.

- For a cheesy variation, sprinkle shredded mozzarella or provolone over the dish during the last 15-20 minutes of cooking.
