Preheat oven to 375 F.
If the pie shell instructions recommend pre-baking, follow those directions. For a filled quiche, pre-baking the shell for10-15 minutes can help prevent a soggy bottom. Remove from oven and set aside.
In a large mixing bowl, whisk the eggs until lightly beaten.
Add the cream and a pinch of salt and pepper; whisk until well combined.
Stir in the diced ham and shredded cheese, ensuring the fillings are evenly distributed.
Place the prepared pie shell on a baking sheet (to watch any potential spills) and pour in the egg mixture. Be careful not to overfill.
Bake for 40-45 minutes, or until the center is set and no longer jiggly. The edges should be light golden brown. A knife inserted near the center should come out mostly clean.
Let the quiche rest for at least 10-15 minutes before slicing and serving. This allows the filling to set further and makes it easier to cut.
