Ingredients

  • 1 tbsp olive oil
  • 1 lb fresh Italian sausage links - nitrate-free (or 6 medium Italian sausage links in their casing)
  • 1 medium onion cut into 1/4-inch-wide strips
  • 3 cloves garlic
  • 8 oz (227) white mushroom sliced
  • 2 red bell pepper cut into 1/4-inch-wide strips
  • 1 1/2 cup any tomato sauce (I prefer homemade tomato sauce or you can use 28oz can of crushed tomatoes)
  • Coarse salt and ground black pepper to taste
  • Fresh parsley for garnishing

Instructions

  • Over medium-high, heat olive oil in a large skillet. Add sausage links, and cook for about 2 minutes each side, just until they get brown (but the sausage will not be cooked though).

Notes

  • Click HERE to watch the web story. 
  • For an easier clean-up, use a slow cooker liner. 
  • I like using red bell peppers as they're sweeter. You can also use orange or yellow bell peppers.
  • To save prep time, buy pre-sliced mushrooms. 
  • Do not skip searing the ingredients in your skillet before adding to the slow cooker. It adds a ton of flavor to the overall dish.
  • To store: Store leftovers in the refrigerator for up to 4 days in an airtight container.
  • To reheat: Reheat leftovers on the stove or microwave.
  • To freeze: Once cooled, you can freeze the recipe for up to 3 months. Make sure to fully thaw in the fridge before reheating.
