Sweet Potato Crust Quiche
To get yours, join Sweetashoney Members!
- 2 Sweet Potatoes medium size orange, peeled, finely sliced
- 1 tablespoon Extra Virgin Olive Oil
- 2 Garlic Clove finely chopped
- 1 Onion finely chopped
- 14 oz Frozen Spinach
- ¼ teaspoon Ground Pepper optional
- ½ teaspoon Salt
QUICHE EGG BATTER
- 4 Eggs
- ¾ cup Unsweetened Coconut Milk or milk of your choice
- ¼ teaspoon Ground Nutmeg
- ¼ cup Grated Cheese edam, cheddar, feta
Preheat oven to 360°F (180°C).
Grease a 9-inch (24 cm) round ceramic quiche dish with butter or coconut oil. Set aside.
In a frying pan, under medium heat warm the olive oil.
Add garlic and onion. Fry until fragrant and golden brown. Stir often to prevent the spices from burning.
Add the frozen spinach cover and reduce to low heat. Cook until the spinach is cooked through, soft and tender – about 15 minutes. Adjust with salt and pepper to taste.
Meanwhile, peel the sweet potatoes then use a mandoline Vegetable Slicer to finely slice the sweet potatoes.
Arrange the slices on the pan making sure that you cover all the bottom leaving no empty space. For the border, cut in half the sweet potatoes slices to create a 'flat' bottom it will hold better and create a beautiful crust border.
Prebake the sweet potato crust at 180°C for 15 minutes. This is optional, you can also add the spinach and egg filling directly and bake your quiche – make sure you cover the dish with a piece of foil to ensure the quiche is cooking at the same speed. I prefer to prebake the crust to avoid using a foil – up to you.
Spread the cooked spinach all over the pre-baked sweet potatoes crust. Set aside.
In a medium mixing bowl beat the eggs, almond milk, and nutmeg. Adjust with salt and pepper if desired.
Pour the egg mixture onto the quiche.
Add a handful of grated cheese on the top of the quiche, if desired. If paleo, sprinkle almond meal on top instead of cheese, it gives a delicious crisp on top.
Bake for 25-30 minutes or until the sweet potatoes are soft and the cheese is grilled.
Storage: Store well in the fridge for up to 4 days. Simply leave the quiche in the pan and wrap it with plastic film to prevent the quiche from drying out. Remove in the microwave or hot oven until hot.
Dairy-free option: Replace cheese with 2 tablespoons of almond meal. Sprinkle on top and bake until crispy.
