Preheat your oven to 350°F (175°C) and line a pie pan with the pie crust.
Evenly spread the cooked and crumbled sausage across the bottom of the crust. Top it with the diced Velveeta cheese and grated Monterey Jack cheese.
In a medium bowl, whisk together the eggs, heavy cream, sour cream, Worcestershire sauce, dried parsley, onion powder, garlic powder, salt, and pepper.
Pour the egg mixture over the sausage and cheese in the pie crust.
Bake the quiche in the preheated oven for approximately 1 hour or until set.
Allow the quiche to rest for 15 minutes before slicing and serving. Get ready to savor each flavorful bite!
