How to Make Crockpot Sausage and Peppers Recipe
Step 1: Combine Ingredients in the Crockpot
Start by placing everything except the fresh basil and parmesan cheese into your crockpot. This means the crushed tomatoes, garlic, oregano, salt, black pepper, Italian sausages, sliced bell peppers, and sweet onions all go in together. Use a gentle hand to mix the ingredients just enough for the flavors to start to mingle. This layering is what builds the complexity of the dish as it cooks.
Step 2: Slow Cook to Perfection
Cover your crockpot and set it to cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours if you’re short on time. The goal here is to let the sausages cook through fully while the peppers and onions soften, releasing their sweetness and blending perfectly with the tomato sauce. The slow simmer allows all the flavors to develop and marry, turning simple ingredients into something truly magical.
Step 3: Final Touches Before Serving
Once everything is cooked and you can smell that incredible aroma filling your kitchen, remove the lid. Sprinkle sliced fresh basil and shredded parmesan cheese over the top—these fresh, vibrant additions brighten up the rich sauce and add a beautiful finishing touch.
How to Serve Crockpot Sausage and Peppers Recipe

Garnishes
Beyond just the fresh basil and parmesan the recipe suggests, consider adding a drizzle of good-quality olive oil or a sprinkle of red pepper flakes if you love a bit more heat. Fresh herbs like parsley or oregano can also enhance the color and flavor for a truly tempting presentation.
Side Dishes
This Crockpot Sausage and Peppers Recipe shines when paired with simple sides like crusty bread or warm sub rolls that are perfect for soaking up the flavorful sauce. Alternatively, serving it over pasta, like spaghetti or rigatoni, turns this into a hearty Italian-inspired meal that’s both comforting and satisfying.
Creative Ways to Present
You can also turn this dish into a loaded sandwich by piling the sausages and peppers into toasted hoagie buns topped with melted provolone or mozzarella cheese. Or, try the mixture as a filling for a savory crepe or alongside creamy polenta for a rustic twist that will impress your guests.
Make Ahead and Storage
Storing Leftovers
Leftover Crockpot Sausage and Peppers store beautifully in an airtight container in the refrigerator for up to 3 to 4 days. The flavors tend to deepen even more after a day, making it just as delicious when reheated.
Freezing
This dish freezes well, too. Just portion it into freezer-safe containers or bags and it will keep for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the fridge for the best texture and flavor.
Reheating
Reheat gently on the stovetop over low heat or in the microwave until warmed through. If it looks a bit thick, stir in a splash of water or broth to loosen the sauce. Be sure to sprinkle on some fresh basil and parmesan again for that fresh, just-cooked touch.
FAQs
Can I use different types of sausage for this recipe?
Absolutely! While Italian sausage is classic for this dish, you can use chicken sausage, turkey sausage, or even a spicy chorizo to customize the flavor to your liking. Just adjust cooking times if necessary to ensure they are fully cooked.
Do I have to peel the garlic for the crockpot?
Yes, peeling the garlic cloves is best for this recipe. Minced peeled garlic blends nicely into the sauce and releases its flavor fully during the slow cooking process.

The recipe itself is naturally gluten-free if you serve the sausage and peppers over gluten-free pasta or enjoy them on gluten-free rolls. Always check your sausage labels to ensure they don’t contain any gluten fillers or additives.
How spicy can this dish be made?
You control the heat by your choice of sausage and how much black pepper or red pepper flakes you add. Opting for hot Italian sausage or adding extra crushed red pepper flakes will amp up the kick for those who love spicy dishes.
