Instructions

Step 1: Combine Ingredients in the Slow Cooker

Place 1.5 lbs Italian sausage (whole or cut into pieces) in the slow cooker.
Add 2 sliced bell peppers, 1 sliced onion, 3 minced garlic cloves, 1 can (14 oz) undrained diced tomatoes, 1 tsp dried oregano, 1 tsp dried basil, and a pinch of salt and pepper.
Stir gently to combine, ensuring the sausage is nestled into the vegetables and sauce.
Tip: Lightly grease the slow cooker with cooking spray to prevent sticking.

Step 2: Cook

Cover and cook on low for 6–7 hours or high for 3–4 hours, until the sausage is cooked through (160°F/71°C internally for pork sausage) and the vegetables are tender.
Check doneness at the lower end of the time to avoid overcooking, as slow cookers vary.
Tip: Avoid lifting the lid during cooking to maintain consistent heat.

Step 3: Serve

Stir the mixture gently to blend the flavors. Taste and adjust salt, pepper, or herbs as needed.
For sandwiches, slice or leave sausages whole and serve on toasted crusty rolls, spooning the peppers, onions, and sauce over the top. For pasta, slice sausages (optional) and toss with cooked pasta, topping with extra sauce.
Garnish with chopped fresh parsley for a vibrant finish.
Tip: Toast rolls or cook pasta just before serving for the best texture. If the sauce is too thin, cook uncovered on high for 10–15 minutes to reduce.
