How to Make Slow Cooker Italian Sausage and Peppers
-
Prepare the vegetables: Wash and slice the bell peppers into thick strips, thinly slice the onion, and mince the garlic. The colorful medley will bring your dish to life!
-
Brown the sausages: Heat olive oil in a large skillet over medium-high heat and brown the sausages for 2–3 minutes per side. This step will lock in those lovely flavors and create a beautiful sear.
-
Layer the veggies: Place half of the sliced bell peppers and onions in the bottom of a 6-quart slow cooker. This forms a cozy bed for the sausages to rest on.
-
Add the sausages: Arrange the browned sausages in a single layer over the vegetables. The sausages should be nestled comfortably, ready to soak up the flavors.
-
Top with remaining veggies: Scatter the remaining bell peppers, onions, and minced garlic around and over the sausages. This adds texture and bursts of freshness to the dish.
-
Mix the sauce: In a mixing bowl, combine crushed tomatoes, diced tomatoes, tomato paste, chicken broth, and all the seasonings: Italian seasoning, oregano, basil, smoked paprika, garlic powder, black pepper, salt, and optional red pepper flakes. Stir well to create a harmonious blend.
-
Pour the sauce: Spread the tomato mixture evenly over the sausages and vegetables, gently shaking the slow cooker insert to help distribute the sauce. Everything should be beautifully coated!
-
Cook it low and slow: Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the peppers are tender and the sausages are fully cooked. The longer, the better—flavors will deepen!
-
Check for doneness: Use a meat thermometer to ensure chicken sausages reach 165°F (74°C) and beef sausages reach 160°F (71°C). This step is key for food safety!
-
Thicken the sauce (if needed): If the sauce is too thin, remove the lid and cook on HIGH for another 15–20 minutes, stirring gently. This will help achieve a luscious consistency!
-
Serve with love: Spoon the rich tomato sauce over the sausages and adjust the seasonings, if necessary. Taste testing ensures perfection before serving!
-
Garnish: Sprinkle with fresh chopped parsley and serve warm directly from the slow cooker. That finishing touch brings vibrancy to your dish!
