Step-by-Step Instructions

Brown the Sausages
Heat olive oil in a skillet over medium-high heat. Sear sausages on all sides until lightly browned. This step enhances flavor and prevents a pale finish during slow cooking.
Prepare the Vegetable Base
Place sliced peppers and onions into the slow cooker, creating an even layer that will absorb the sausage juices.
Add Aromatics and Sauce
Add garlic, crushed tomatoes, tomato paste, chicken broth, Italian seasoning, oregano, paprika, chili flakes, salt, and pepper. Stir gently to combine.
Layer the Sausages
Nestle browned sausages on top of the vegetables and sauce mixture to allow even cooking.
Slow Cook to Perfection
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until sausages are tender and flavors fully developed.
Finish and Adjust Seasoning
Taste the sauce before serving and adjust seasoning if needed. Garnish with fresh herbs for brightness.
