I recently watched an episode of Cook Yourself Thin where a quiche was made using a potato crust. It seemed like a great idea and one that I couldn’t wait to try out.
A crust made up of shredded potatoes is definitely a healthy alternative to the usual fat-laden pastry crusts I’ve seen used in most quiche recipes. I followed the recipe very closely and did not make too many changes. I had a crisper full of vegetables in the refrigerator, and so I used a little bit of everything for this quiche.
Here’s what I did…
For the crust:
3 potatoes peeled and grated (I used Russet)
2 tsp oil
For cooking in a pan:
2 Tbsp oil
4 cloves of garlic, minced
½ onion, diced
1 tsp red pepper flakes
¼- ½ tsp dried thyme (optional)
4 cups sliced mushrooms,
1 cup chopped red bell pepper
½ cup chopped asparagus
2 cups baby spinach
For the custard:
3 eggs, beaten
¼ cup milk
3 Tbsp freshly grated Gouda cheese
Preheat oven to 400 degrees F. Grease a 9-inch pie dish/plate (I used glass) with some oil. Squeeze all the excess water out of the grated potatoes. Toss grated potatoes with oil, salt, and pepper. Press into an even layer in pie dish, up the sides like a crust. Bake until golden brown at the edges and dry, about 20-22 minutes. Then broil for 2 minutes or so. Watch the crust carefully here so that it does not burn. Let cool.
Lower the oven temperature to 350 degrees F. Heat oil in a large skillet, over medium heat. Add onion and cook until soft. Add mushrooms and cook, stirring, until mushrooms release their liquid and most of the liquid evaporates. Stir in the chopped asparagus and red bell pepper pieces. Cook till the vegetables soften. Add spinach and cook, stirring, just until spinach wilts, let cool slightly.
Whisk together eggs, milk, salt, and pepper. Spread the vegetable mixture in an even layer in the pie dish. I used all but one cup of the cooked vegetable mixture here since I thought it would be a little too much for the quiche. Sprinkle the grated cheese evenly over the vegetable mixture. Carefully pour in egg mixture.
Bake until golden brown and set in the center, about 30-35 minutes. Let cool, and serve warm or at room temperature.
