  • Mixing Bowl
  • 9x13 Baking Dish
  • Large Skillet


  • 4 medium Zucchini
  • 1 Bell Pepper chopped
  • 1 Yellow Onion chopped
  • 4 cloves Garlic minced
  • 1 Tablespoon Olive Oil
  • 2 Eggs
  • 1 lb. Turkey ground
  • 2 cups Marinara Sauce
  • 2 cups Mozzarella Cheese shredded
  • ¼ cup Parmesan Cheese grated
  • 1 Tablespoon Italian Seasoning divided
  • ½ teaspoon Black Pepper
  • ½ teaspoon Onion Powder


  • Preheat oven to 400 degrees.
  • Grate the zucchini, place it in a colander, and drain the excess moisture with the back of a spoon.
  • In a mixing bowl, combine the zucchini, eggs, parmesan cheese, black pepper, onion powder, and 1 teaspoon of the Italian seasoning.
  • Press the mixture into a lightly greased 9x13 baking pan and bake for 20 minutes.
  • Meanwhile, heat oil in a large skillet over medium heat. Saute the onion and bell pepper until soft and the onion is translucent.
  • Add the garlic and cook for another minute.
  • Add the ground turkey and cook thoroughly. Stir in the marinara sauce and 1 teaspoon of the Italian seasoning.
  • Remove the zucchini crust from the oven and spread the sauce mixture evenly on top.
  • Sprinkle on the mozzarella cheese and the remaining 1 teaspoon of Italian seasoning. Bake for an additional 20 minutes.


  • Four medium zucchini will produce 4 cups of grated zucchini (firmly pack in the measuring cup).
  • I choose to use a red bell pepper because it contains more beta carotene and vitamin C than a green bell pepper.
