Start by rinsing the large fresh shrimp under cold water to ensure they are clean. Once rinsed, pat them dry thoroughly with paper towels, which is crucial for achieving a nice sear. Set the shrimp aside while you prepare the flavorful sauce.

In a large skillet, melt 4 tablespoons of butter over medium heat. Allow it to foam slightly but be careful not to let it brown.

Add the minced garlic and chopped onion to the skillet with the melted butter. Sauté these for 3-4 minutes, stirring frequently, until you notice the onion becoming translucent and fragrant.

Stir in Worcestershire sauce, fresh lemon juice, hot sauce, paprika, cayenne pepper, black pepper, and salt into the skillet. Let this mixture simmer for 2-3 minutes.

Add the prepared shrimp to the skillet, ensuring they are thoroughly coated in the saucy mixture. Cook the shrimp for about 5-7 minutes, stirring gently until they turn pink and opaque.

Remove the skillet from heat and transfer the shrimp to a serving dish. Garnish generously with freshly chopped parsley and serve immediately.
