  • 2 pounds sweet Italian sausage
  • 3 medium bell peppers thinly sliced (red, orange, yellow, green, or a mix)
  • 2 medium yellow onions thinly sliced
  • 1 (25 ounce) jar marinara sauce

Optional serving suggestions:

  • 6 sausage rolls or hoagie rolls, 1 pound cooked pasta (any shape), garlic bread, shredded Italian cheese blend, parmesan cheese, cooked spaghetti squash, or cauliflower rice


  • Add the sausage, bell peppers, onion, marinara, and salt to a 6-quart slow cooker.
  • Stir to combine, then cover. Cook on high for 4-5 hours or low for 7-8 hours. Do not uncover during this time.
  • Carefully remove the sausage and slice into 1-inch pieces. Add back to the slow cooker and stir. Taste, and adjust seasoning if desired.
  • Serve warm on rolls, over pasta, with bread, cooked spaghetti squash, or cauliflower rice.


Because of the salt in the marinara and sausages, this recipe does not call for additional salt. However, because sausage and marinara brands differ in sodium, I suggest tasting the sauce at the end and adding salt if desired. For a low sodium option, use low sodium marinara.
