Duchess Cauliflower Casserole
Makes 6 servings (1/2 cup each)
20 ounces frozen riced cauliflower
2 tablespoons heavy cream [sub coconut cream]
1 tablespoon unsweetened coconut milk
1 large egg, separated
1/2 teaspoon sea salt
A pinch of garlic powder
4 tablespoons melted unsalted butter [sub ghee], divided
Preheat the oven to 450 degrees Fahrenheit.
Heat riced cauliflower in a large saucepan until thawed and most of the excess liquid has evaporated. Remove from heat and puree in a food processor until a mashed potato consistency is reached.
Whisk together heavy cream, coconut milk, egg yolk, sea salt, and garlic. Stir this mixture into the mashed cauliflower along with 2 tablespoons of the melted butter until well combined.
Grease a small casserole dish and spread the cauliflower mash evenly in the dish.
Whisk together the egg white, remaining 2 tablespoons of melted butter, and a pinch of sea salt. Pour 1/2 to 3/4 of the egg white mixture on the top of the cauliflower mash. Tilt the pan and allow the egg white mixture to flow into the corners and all over the top until evenly coated. Use the flat side of a sharp knife to carve a diamond pattern into the top of the casserole, pressing only about 1/4 inch into the surface.
5. Place in the preheated oven on the middle rack and bake for 25-30 minutes, turning 1/2 way through cooking. Bake until the crust is a nice golden brown. Remove from oven and allow to rest for about 15-20 minutes before serving.
