Ingredients
  

  • 4 medium zucchini grated (approx 4 cups)
  • 2 large eggs lightly beaten
  • 1/2 cup Fresh grated Parmesan cheese
  • 2 cups shredded Italian blend cheese divided
  • 2 teaspoons cracked black pepper
  • 4 ounces Colby Jack cheese (1 cup) shredded
  • 1 pound keto Italian sausage
  • 1 medium onion chopped
  • 8 ounces cremini mushrooms sliced
  • 3 cloves garlic minced
  • 2 roma tomatoes chopped
  • 1 tablespoon Italian seasoning blend
  • pink salt
  • 1 (15-ounce) can crushed tomatoes
  • fresh flat-leaf parsley chopped (for garnish)

Instructions
 

  • Place zucchini in a strainer over a bowl. Sprinkle with salt 1/2 teaspoon salt. Mix in the salt and stand for 15 minutes. Using a clean dish towel, wring out as much moisture as possible.
  • Preheat oven to 400 degrees F.
  • Spray a 13×9-in baking dish with non-stick spray.
  • In a large bowl, combine zucchini with the eggs, Parmesan, and half of the mozzarella and cheddar cheeses. Press into the baking dish. Bake, uncovered, at 400° F for 20 minutes.
  • Meanwhile, cook mushrooms, in a large skillet, over medium heat until they begin to soften, about 5 mins, add the onions and cook for an additional 3 minutes. Add the garlic and crumble the sausage in. Cook until the meat is no longer pink. Add tomato sauce, chopped tomatoes, basil, salt, and pepper, and bring to a bubble, reduce the heat and simmer for 5 minutes, or until the sauce thickens. Spoon into the baking dish, sprinkle with remaining cheeses, and bake 20 minutes longer or until heated through.
  • Remove from the oven and top with the chopped parsley.
