01 - Set oven to preheat at 350°F.
02 - Fit the pre-made pie crust into a 9-inch pie dish, pressing gently to conform to the shape. Set aside.
03 - Heat butter or oil in a skillet over medium heat. Add finely chopped onion, diced bell pepper, and minced garlic. Cook until vegetables soften, about 5 minutes.
04 - Add peeled and deveined shrimp to the skillet and cook for 3 to 4 minutes until pink and opaque. Remove from heat and allow to cool slightly.
05 - In a large bowl, whisk together heavy cream, eggs, mayonnaise, Worcestershire sauce, Old Bay seasoning, salt, and pepper until fully combined.
06 - Incorporate sautéed vegetables, cooked shrimp, shredded cheddar cheese, and chopped parsley into the cream mixture. Stir thoroughly to ensure even distribution.
07 - Pour shrimp filling into prepared pie crust. Level the surface with a spatula.
08 - Transfer to preheated oven and bake for 30 to 40 minutes, or until the filling is set and the top is golden brown. Shield crust edges with foil if they brown too quickly.
09 - Remove pie from oven and let cool for 15 to 20 minutes before slicing. Garnish with parsley and lemon wedges as desired.
