  • 2 packs Italian Sausage (10 Sausages either hot or mild)
  • ½ cup water
  • 24 or 25.5 oz Low Carb Marinara Sauce (with no added sugar) *see list below of sauce options
  • 1 ½ cup mozzarella cheese
  • ¼ cup Parmesan Cheese
  • ¼ tsp Italian seasonings
  • ¼ tsp garlic powder
  • ½ tsp basil seasoning
  • pepper


  • Brown Italian sausage links in a skillet set over medium heat on both sides.
  • Add ½ cup water and simmer on low with the lid on for 8 min.
  • Put sausages in a greased 9 x 13 casserole dish.
  • Pour 24 oz marinara sauce over the top.
  • Sprinkle 1 ½ cup shredded mozzarella cheese and ¼ cup Parmesan cheese over top of your sausages.
  • Sprinkle seasoning on top of cheeses.
  • Bake in a 375°F oven and for 18 minutes, then move to the top rack of the oven for the last 2 minutes. If you like the cheese extra bubbly and browned, you can turn the oven to broil for the last minute but watch closely!
