Set your oven to preheat at 375°F (190°C).
Heat a large skillet over medium-high and add the bacon. Cook, turning occasionally, until crispy and golden brown, about 10 minutes. Once cooked, transfer the bacon to a paper towel-lined plate to drain, then chop into small pieces once cooled.
Gently press the pie crust into a 9-inch pie dish, ensuring it fits snugly, and set it aside for later use.
In a bowl, whisk together the eggs, cream, hot pepper sauce, Worcestershire sauce, salt, and pepper until smooth and well combined.
Layer the spinach evenly over the bottom of the pie crust. Add the bacon, Cheddar cheese, and green onion on top, then pour the egg mixture over everything. Finish by sprinkling Parmesan cheese on top for a golden, flavorful finish.
Bake the quiche in the preheated oven for 35 to 45 minutes, or until the top is golden and slightly puffed, and a knife inserted into the center comes out clean.
