**For the Crust:**

  • 1 tablespoon olive oil
  • 1 tablespoon cornmeal*
  • 2.5 cups grated sweet potato moisture removed and packed (about 1 large sweet potato)*
  • 1 teaspoon salt separated
  • 1 large egg
  • 1 tablespoon garlic powder
  • 1/4 teaspoon ground cloves
  • 1/8 teaspoon ground pepper
  • 3/4 cup super-fine almond flour

**For the Quiche:**

  • 8 large eggs
  • 1/4 cup milk any kind
  • 1/2 teaspoon sea salt
  • 1 large white onion caramelized**
  • 2 cups fresh spinach packed
  • 1 red pepper chopped
  • 1/4 cup sun-dried tomatoes
  • 2 oz. goat cheese crumbled


**For the Crust:**

  • Preheat oven to 425°F and grease a 9-inch circular pan (a 2.5-inch deep cast iron pan works well) with olive oil and sprinkle with cornmeal to prevent sticking.
  • Peel and grate the sweet potato using a cheese grater.
  • Transfer the grated sweet potato to a bowl, sprinkle with 1/2 teaspoon salt, and let it sit for 15-20 minutes to draw out moisture.
  • Remove excess moisture from the sweet potato by squeezing it with paper towels.
  • In a medium-sized bowl, combine the sweet potato with the remaining salt, egg, garlic powder, cloves, pepper, and almond flour. Mix thoroughly.
  • Press the sweet potato mixture into the greased pie pan to form a crust covering the bottom and halfway up the sides.
  • Bake the crust at 425°F for 20 minutes.

**For the Quiche:**

  • Allow the crust to cool while prepping the vegetables. Prepare 2 cups of packed spinach, caramelize a large white onion, and chop a red pepper.
  • Whisk together eggs, salt, and milk in a medium bowl.
  • Layer caramelized onion, spinach, and red pepper on the cooled crust, then pour the egg mixture over the veggies.
  • Top with sun-dried tomatoes and goat cheese.
  • Cover with foil and bake at 425°F for 20 minutes. Remove foil and bake for an additional 10-15 minutes until set.


  • You can substitute almond flour for cornmeal to make this recipe grain-free.
  • If using a 10-inch pan, add 2 extra large eggs to cover the vegetables.
