Helpful Tips
- Browning the sausages in a skillet before adding them to the crockpot enhances their flavor and texture. It’s worth the extra step for that rich, caramelized taste.
- Cut the bell peppers into uniform strips to ensure they cook evenly and look great when served. Consistent sizes also ensure perfect texture in every bite.
- Add red pepper flakes for heat or use sweet sausage for a milder version. Adjust the spices to suit your family’s preferences.
- Fresh garlic adds depth and richness to the sauce. Mince it finely for even distribution and maximum flavor.
- Place the peppers and onions at the bottom of the crockpot to create a flavorful base, and layer the sausages on top. This helps distribute the juices evenly.
- Opt for high-quality canned tomatoes for the best flavor. Fire-roasted tomatoes are a great option for added smokiness.
- Resist the urge to open the lid while cooking, as this can affect the temperature and extend the cooking time. Let the crockpot do its job undisturbed!
Optional Ingredients
- Mushrooms: Add sliced mushrooms for extra umami and texture. They soak up the sauce beautifully.
- Zucchini: Include chopped zucchini for a light, fresh addition to the dish. It’s a great way to sneak in some extra vegetables.
- White Wine: Deglaze the skillet with white wine after searing the sausages for added depth of flavor. The wine adds a subtle tangy note to the sauce.
- Cheese: Sprinkle shredded mozzarella or Parmesan over the dish before serving for a cheesy finish. Melted cheese makes everything better!
- Balsamic Vinegar: Add a splash of balsamic vinegar to the sauce for a tangy, slightly sweet note. It elevates the flavor profile.
- Fresh Herbs: Garnish with fresh basil or parsley for a burst of color and flavor. Herbs add a finishing touch that makes the dish look and taste amazing.

How to Enjoy Crockpot Sausage and Peppers?
Always arrange this dish carefully when serving. My favorite way is to serve the sausages and peppers over a bed of fluffy white rice or creamy mashed potatoes. The sauce soaks into the base, creating an incredibly satisfying bite that warms you from the inside out.
Pair this dish with a simple green salad and a slice of garlic bread for a complete and balanced meal. The freshness of the salad complements the richness of the sausages and sauce, while the bread is perfect for mopping up every bit of the delicious tomato sauce. For an extra indulgent touch, add a dollop of sour cream or a sprinkle of grated cheese on top.
You can also serve it as a sandwich. Place the sausages and peppers in a toasted hoagie roll, top with melted provolone or mozzarella, and enjoy a hearty, portable meal that’s perfect for parties or lunches on the go. It’s a guaranteed crowd-pleaser that always leaves guests asking for the recipe.
Recipe Variations
Spicy Sausage and Peppers: Use hot Italian sausage and extra red pepper flakes for a fiery version of this dish. It’s perfect for those who love a little heat.
Vegetarian Version: Replace the sausage with plant-based sausage or grilled tofu and add extra vegetables like eggplant or zucchini. This variation is just as hearty and flavorful.
Cheesy Sausage Bake: Transfer the cooked sausage and peppers to a baking dish, top with shredded mozzarella, and broil until bubbly. It’s a great way to enjoy a cheesy twist.
Creamy Sausage and Peppers: Stir in a few tablespoons of heavy cream or mascarpone cheese for a rich, creamy sauce. This version is ultra-indulgent.
Herb-Infused: Add fresh rosemary or thyme to the crockpot for an aromatic twist. The herbs elevate the dish with a delightful fragrance.
Tex-Mex Twist: Replace the tomato sauce with salsa, add black beans, and serve with tortillas for a southwestern-inspired version. It’s a flavorful fusion everyone will love.
How to Store
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop until warmed through. For an extra fresh touch, add a sprinkle of fresh herbs before serving.
For longer storage, freeze the sausage and peppers in individual portions. Let the dish cool completely before transferring to freezer-safe containers. To reheat, thaw overnight in the refrigerator and warm in a skillet or microwave. The flavors deepen over time, making it even tastier the next day. This recipe is as convenient as it is delicious!
