  • Prep Time: 5 mins
  • Cook Time: 45 mins
  • Total Time: 50 mins

Yield: Serves 4



Zucchini “crust”:

  • 2 large zucchini, grated and moisture squeezed out (this is key!! squeeze out the water!)
  • 1 egg
  • 1/4 cup coconut flour (I haven’t tested another flour)
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • Sea salt and black pepper to taste


  • 1 lb ground meat of choice (sausage, turkey, chicken and pork all work so well!)
  • 2 cups red sauce of choice
  • 1 cup shredded mozzarella cheese (can use dairy-free too)
  • Red pepper flakes and basil for topping if desired


  1. Preheat oven to 400 degrees and grease a 10-12 inch cast iron skillet or 9×9 baking dish
  2. In a large bowl, mix together zucchini crust ingredients together until fully combined
  3. Add to skillet and press down with your hands or spatula to make “crust” then bake in oven for 20-25 minutes (until it gets a little golden!)
  4. Meanwhile, cook the meat in a large skillet until cooked (no pink!)
  5. Turn off heat and add in sauce and mix well
  6. Add the meat/sauce topping on top of zucchini crust then sprinkle cheese on top and bake in oven for 20-25 minutes and add any pepper flakes or basil if using
  7. Serve while warm!


*Store leftovers in fridge for 5 days. I don’t recommend freezing this

**Squeezing out moisture from zucchini is so key! If this is skipped, the crust will be a bit watery
