  • 2 tablespoons coconut oil
  • 1 medium shallot, minced (about 1/4 cup)
  • 2 cloves garlic, minced (about 1 tablespoon)
  • 1 tablespoon cassava flour
  • 1 1/2 cups coconut milk

To make the filling

  1. Bring 2 quarts water to boil in a large pot and add 1 teaspoon salt. Add cauliflower and cook for just 2-3 minutes, until lightly tender. Drain into a colander and rinse with cold water and allow to dry as much as possible.

To assemble and bake

  1. Arrange cauliflower in a 3 quart casserole or gratin dish.
  2. Pour coconut milk mixture over cauliflower and mix gently to insure all cauliflower is evenly coated.
  3. Sprinkle the topping evenly over the filling.
  4. Bake for about 10 minutes, or until golden brown on top and sauce is bubbling.
