Notes

  • Make it Vegetarian: Use 1/2 pound vegetarian Italian sausage, like Beyond Italian Sausage. Chop sausage and fry until heated through before adding marinara, water, cream cheese, and heavy cream.
  • Net carb count will vary depending on the brands of ingredients you use, especially the marinara sauce. I like to use Rao's marinara, which only adds 15g net carbs to this entire dish - 1.25g net carb per serving!
