Quiche is a favorite of many, but for some, the classic crust is not compatible. Swap out the white, processed flour with sweet potatoes for a healthy and gluten-free option.
Choose potatoes roughly the same size and diameter for more uniform cuts. To make slicing easier and quicker, try using a mandolin or a food processor.
Spinach & Feta Quiche with Sweet Potato Crust
- 2 medium sweet potatoes
- ½ cup onions, sliced
- 1 bag fresh baby spinach
- 1/4 teaspoon salt
- ½ cup milk of choice
- ¼ teaspoon black pepper, fresh ground
- ¼ teaspoon crushed red pepper
- 4 eggs
- 2 egg whites
- ⅓ cup feta cheese, crumbled
- Cooking spray
Prepare the crust
- Preheat the oven to 350F.
- Peel sweet potatoes and cut into ⅛ inch slices.
- Coat a 9-inch pie plate with cooking spray. Layer with sweet potatoes. Around the edges, cut the slices in half to fit.
- Coat the potatoes with cooking spray.
- Bake in the oven at 350F for 20 minutes or until tender.
- Remove pan from oven and place pan on a wire rack.
Prepare the Filling
- Turn oven up to 375F.
- On the stove, heat a large skillet on medium.
- Add oil and onions and saute them for 3 minutes; then add the spinach and saute for another 3 minutes.
- Then remove the onions and spinach from heat to let cool.
- Meanwhile, combine the milk, salt, pepper, eggs, and egg whites in a bowl. Whisk.
- Arrange spinach mixture in the crust and pour egg mixture over top. Sprinkle with feta cheese.
- Bake at 375F for 30 minutes or until the egg mixture is set.
- Let stand for 5 minutes.
- Cut into 8 wedges and serve.
Serve your quiche for any meal. As a breakfast dish, add a side of fruit salad. For lunch or dinner, pair with a hearty chicken or vegetable soup or my favorite: bacon-wrapped asparagus. Double your recipe for leftovers.
Recipe Swaps
For an alternative, dietary-restricted option, use nondairy milk such as almond or cashew milk. Make sure to avoid oat milk unless it’s certified gluten-free. For a feta cheese alternative, try Violife Feta Block or try your hand at your own fresh-made version.
Vegan Almond Feta Cheese
- 1 ½ cups of raw almonds
- ¼ cup nutritional yeast
- ⅓ cup lemon juice
- ¼ cup olive oil
- 2 cloves garlic
- ⅓ cup + 4 tsp water
- Salt to taste
Instructions
- Soak the almonds in 2 cups of extra hot water for 2 hours.
- Skin almonds.
- Add the almonds and 1 ½ cups water into a food processor. Blend until it becomes a smooth paste.
- Add other ingredients and process until smooth. Add 1 tablespoon of extra water at a time if needed.
- Refrigerate for a couple of hours to firm up. For a thicker mixture, allow to refrigerate overnight.
Notes
As you begin processing, the mixture may look more like a nut milk. It will firm up as the nuts are processed and break down. Use less water to keep a firmer texture. When the processing is done, add the cheese to a small container and allow it to firm up overnight. The texture won’t be the same as cow’s milk feta, but the difference is a small price to pay if the dairy version will wreak havoc on your insides.
Refrigerate and use within 4 to 5 days as the raw nuts and softness means it may not last as long as other cheese you’re used to. To freeze, split into separate, well-sealed containers and toss in the freezer.
