Substitutions
To make quiche with potato crust vegetarian do not add the sausage.
You can also make it dairy free by using a plant-based milk and cheese. Although, I haven’t tested the recipe using replacements for milk and cheese.
If you avoid lactose you can use aged cheeses in the filling of the quiche. An example is Parmesan. This cheese is naturally lactose free, because it is aged. During the aging process the bacteria eats up all the lactose. The amount of the lactose is insignificant if the cheese is aged long. Those cheeses have hard, chalky texture and sharp, nutty smell.

Instructions
- Wash and peel three russet potatoes (about a pound and a half). Chop them to big pieces (2 inches each). Place them in a pot with cold water and bring them to a boil. When the water is boiling add salt to taste. Boil for 10-15 minutes or until the potatoes are completely cooked.
- When the potatoes are boiled, drain the water and mash them with a fork. Set aside and allow them to cool off slightly.
- While the potatoes are cooling off preheat your oven to 380F and prepare the filling. In a deep bowl whisk 4 eggs and a ½ cup of milk. Chop the mushrooms, sausage, and green onions and add them to the bowl. Then add the added shredded Gouda and add salt and pepper to taste. Stir well.
- To prepare the crust combine the mashed potatoes with ½ cup grated parmesan, salt and pepper to taste. Using your fingers spread the mixture to the bottom and sides of a round 9 inch pie dish.
- Add the filling to the pie dish and bake for 20-25 minutes or until the quiche is completely set in the center and golden brown. Serve it topped with fresh herbs or chopped green onions (optional).
