Ingredients

  • 2 pounds Italian sausage (mild or hot, whole or sliced)
  • 1 tablespoon olive oil
  • 1 large yellow onion (sliced)
  • 3 bell peppers (red, green, yellow – sliced)
  • 3 garlic cloves (minced)
  • 1 (14.5 oz) can diced tomatoes
  • 1 (8 oz) can tomato sauce
  • 1 teaspoon Italian seasoning
  • ½ teaspoon salt (or to taste)
  • ½ teaspoon ground black pepper
  • Optional: crushed red pepper flakes (to taste)

Instructions

  1. In a skillet over medium heat, heat olive oil and brown the sausages on all sides (about 5-6 minutes). This step is optional but adds flavor.
  2. Place the sausages in the bottom of the slow cooker.
  3. Top with sliced onions, bell peppers, and garlic.
  4. Pour diced tomatoes and tomato sauce over the vegetables.
  5. Sprinkle with Italian seasoning, salt, pepper, and red pepper flakes if using.
  6. Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the sausage is fully cooked and the vegetables are tender.
  7. Serve hot over rice, pasta, or in toasted hoagie rolls.

Notes

  • Browning the sausages first adds extra flavor but can be skipped if you’re short on time.
  • Use sweet or hot Italian sausage based on your preference.
  • Leftovers can be stored in the fridge for up to 4 days or frozen for up to 3 months.
  • Add more crushed red pepper if you prefer it spicier.
