Preparation
Turn the oven on high heat (375°F, 190°C).
2. Line a 9-inch pie plate with the rolled-out pie crust. After you poke the bottom with a fork, trim the edges if necessary. Cook the crust for 8 to 10 minutes, or until it turns a light golden color. After taking out of the oven, place aside.
Blend the eggs, heavy cream, whole milk, salt, pepper, and nutmeg in a large bowl until thoroughly blended.
4. Until uniformly distributed, stir in the grated Gruyere, Swiss, and cheddar cheeses.
5. Once the pie crust has been prebaked, pour the egg mixture into it.
6. After the oven is warmed, bake the quiche for 30–35 minutes, or until the filling sets and the top starts to turn a slight golden color.
Step7: Take the quiche out of the oven and allow it to cool for five to ten minutes before cutting it into slices and serving.
