Going the traditional route with pastry or opting for a frozen option aren’t the only ways to provide your quiche with a crust — you can also try a savory, crisp potato crust.
A potato crust adds a layer of heartiness to quiche and boasts the added nutrition from the root veggies, including fiber, vitamins C and B6, potassium, and calcium.
You can use fresh or leftover mashed potatoes to create a sort of “dough” and then spread it on a pie plate the same way you would with traditional dough.
You can also go au gratin style for your crust by thinly slicing potatoes on a mandolin and layering and overlapping them as a crust in your pie plate before pouring in your egg filling.
Lastly, you can use prepped shredded potatoes and create a sort of crust around your pie plate by brushing them with butter and baking before layering in other ingredients.
