Preheat the Oven: Preheat your oven to 375°F (190°C).

Prepare the Filling: In a large mixing bowl, combine the softened cream cheese, sour cream, shredded cheddar cheese, hot sauce, and Worcestershire sauce. Mix until smooth and creamy.

Add the Ham and Onion: Stir in the diced ham and chopped green onion, ensuring they are evenly distributed throughout the mixture.

Whisk the Custard: In a separate bowl, whisk together the heavy cream and eggs until well combined. Gradually fold the egg mixture into the cheese and ham mixture.

Assemble the Quiche: Place the pie crust in a deep 9-inch pie pan. Pour the filling into the crust, spreading it evenly.

Bake: Place the quiche on the center rack of the preheated oven. Bake for 35–40 minutes, or until the filling is set and the top is lightly golden. A knife inserted in the center should come out clean.

Cool and Serve: Allow the quiche to cool for 5–10 minutes before slicing. Serve warm and enjoy!
