Spinach and Feta Quiche

Spinach and Feta Quiche with Sweet Potato Crust

The food served on our tables has never been more analyzed and talked about before. Nowadays, more and more people are turning to healthier lifestyles, which include healthier dietary habits as well.

People have adopted various eating styles in the pursuit of health and wellness, so consumers became interested in foods that meet the needs of their specific eating patterns, such as gluten-free, vegan, paleo or keto-friendly.

Therefore, we decided to suggest a gluten-free alternative to your favorite quiche, and you will love it!

Instead of the classic crust out of white flour, you can now use sweet potatoes, and reap all their health benefits!

Sweet potatoes are abundant in fiber, vitamins, and minerals. They also improve eye health, may improve brain function and strengthen immunity, promote gut health, and are reported to have cancer-fighting properties.

This lighter version of the classic feta quiche dish contains low-fat milk and fresh spinach, which additionally enrich the flavor and boost its nutritional value.

Vegans can make their own homemade almond feta cheese to use in the recipe:

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


Place the almonds in 2 cups of extra hot water, and leave them to soak for two hours. Next, skin them, and blend them with 1 ½ cups water in a food processor.

Add the rest of the ingredients, and blend until you get a smooth paste. Leave it in the fridge for a few hours to firm up, or overnight, for a thicker mixture.

It may not last as long as other kinds of cheese, so refrigerate it and use within 4 to 5 days.
