Ingredients
  

  • 2 pounds Italian sausage links
  • 1 yellow onion
  • 2 cloves garlic minced
  • 2 red peppers seeded and sliced about ¼-inch thick
  • 2 yellow peppers seeded and sliced about ¼-inch thick
  • 1 green pepper seeded and sliced about ¼-inch thick
  • 1 tablespoon Italian seasoning
  • 24 ounces marinara sauce

Instructions
 

  • Pour the marinara sauce into the slow cooker insert and set it to high. Cover and let it warm up while prepping the other ingredients.
  • Heat a large skillet over medium-high heat and sear the sausage links until golden brown on the outside, turning occasionally. No need to cook them through. If the sausages are lean, add a little oil to prevent sticking. Transfer them to the slow cooker, placing them on top of the sauce.
  • Cook the sliced onions over medium heat until soft, about 8 minutes. Add minced garlic and stir for another minute until fragrant. Transfer the mixture to the slow cooker, spreading it over the sausages.
  • Evenly distribute the sliced bell peppers over the onion layer. Sprinkle with Italian seasoning.
  • Cover and cook on high for 3 hours or low for 5 hours, until the sausages reach an internal temperature of 165°F.
  • Serve in toasted buns with cheese, over pasta, or with creamy polenta for a comforting meal.

Notes

Chef Jenn's Tips

  • Want more spice? Use hot Italian sausage instead of mild.
  • Searing the sausage adds flavor but can be skipped if short on time.
  • For a thicker sauce, remove the lid in the last 30 minutes of cooking to let some liquid evaporate.
  • The flavors deepen overnight, making leftovers even tastier!
