Preheat your oven to 375°F.
Place the pie crust in a 9-inch pie dish and prick the bottom with a fork.
In a large mixing bowl, combine eggs, heavy cream, salt, and pepper.
Whisk until the mixture is smooth.
Spread the chopped spinach evenly in the pie crust.
Sprinkle the crumbled bacon and shredded Swiss cheese over the spinach.
Pour the egg and cream mixture evenly over the layered ingredients in the crust.
Ensure everything is well coated.
Bake the quiche in the preheated oven for about 35-40 minutes.
The center should set and the top should turn light golden brown.
