The combination of sausages and bell peppers is a classic, and when made in the slow cooker, this recipe is full of flavor and comes together easily. A mixture of onions, peppers, garlic, tomatoes, red wine, and Italian seasoning complements the Italian sausage, making for the perfect pasta topping or sandwich filling. It's also delicious eaten all on its own.

Even if the sausage is fully cooked, it does need to be browned before adding to the slow cooker to remove excess fat and achieve a nice color and texture. Then all you need to do is layer the ingredients in your crockpot, wait a few hours, and then enjoy this delicious Italian slow cooker sausage and peppers tonight.

Italian sausage comes in two flavors: hot and sweet. They both contain fennel, garlic, and onion, but the hot also have crushed red pepper flakes. Use the variety you like best.


  • 2 pounds sweet or hot Italian sausages
  • 2 onions (chopped)
  • 2 red peppers (cut into 2-inch pieces)
  • 1 orange or yellow bell pepper (cut into 2-inch pieces)
  • 2 cloves garlic (minced)
  • 1 (14-ounce) can diced tomatoes (undrained)
  • 1 (8-ounce) can tomato sauce
  • 1/2 cup dry red wine or beef broth
  • 1 tablespoon dried Italian seasoning
  • 1/4 teaspoon pepper

Steps to Make It

  1. Gather the ingredients.

  2. Cook the sausage in a heavy skillet over medium heat until browned, turning occasionally.

  3. Layer half of the onions on the bottom of a 4-quart crockpot, then add half of the peppers. Add all of the browned sausage, then the rest of the onions and peppers.

  4. Add the diced undrained tomatoes, tomato sauce, and the red wine to the skillet and cook over medium heat for 2 to 3 minutes, stirring to loosen the brown bits on the bottom of the pan. Pour this sauce over the sausage and peppers in the crockpot.

  5. Cover the slow cooker and cook on low for 6 hours.

  6. Add the dried Italian seasoning and pepper to the crockpot and stir well.

  7. Cover and cook for 1 more hour until the sausage is thoroughly cooked to 160 F (as measured with a food thermometer), and the vegetables are tender.

  8. Serve and enjoy.


You can begin the process of browning the sausage by adding about 1/3 cup of water to the skillet. This starts to cook the sausages and helps them brown more evenly.
