Preheat the oven to 375˚F and butter a 9x13 baking dish.
Arrange the shrimp in the baking dish in a single layer. Set aside.
In a mixing bowl, combine the softened butter, breadcrumbs, sherry, garlic, shallot, parsley, salt, pepper, paprika, and cayenne; mash and mix until thoroughly combined.
Spoon the breadcrumb mixture over the shrimp.
Bake for 22 to 25 minutes or until the top is golden brown.
Remove the shrimp from the oven and let it rest for a couple of minutes.
Sprinkle with fresh parsley and serve.
Notes
Shrimp: Use jumbo shrimp for best results, but if using smaller shrimp, watch them closely to prevent overcooking and toughness.
Sherry Alternatives: I prefer dry sherry for this recipe, but white wine, lemon, or lime juice are acceptable substitutes.
Thawing Shrimp: For frozen shrimp, thaw them thoroughly and always pat dry before cooking.
Make The Topping in Advance: Make the buttery breadcrumb topping a day ahead, keep it in the fridge, and let it warm to room temperature for easy crumble before assembly.
