Ingredients
  

For the casserole
  • 2 pounds large shrimp (21–24 count), peeled and deveined
  • 1 tablespoon Old Bay seasoning (plus 1 tablespoon for the cooking water)
  • 1 tablespoon salt for the boiling water
  • 2/3 cup mayonnaise (full fat for best texture; light can work if needed)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon ground black pepper
  • 1 tablespoon butter, plus more for greasing the pan
  • 1/2 cup panko breadcrumbs (for extra crunch)
  • 4 ounces shredded mozzarella (about 1 cup loosely packed)
  • 4 ounces shredded medium cheddar (about 1 cup loosely packed)

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C). Butter a 2 1/2-quart casserole dish.
  2. Bring a large pot of water to a rolling boil. Add 1 tablespoon salt and 1 tablespoon Old Bay.
  3. Add shrimp to the boiling water and cook until opaque, about 30 seconds. Drain immediately and transfer the shrimp to a bowl.
  4. While the shrimp are still warm, add 2/3 cup mayonnaise, 1/2 teaspoon garlic powder, and 1/2 teaspoon ground black pepper. Stir to coat the shrimp evenly.
  5. Mix in the shredded mozzarella and cheddar. Stir gently so the cheese begins to melt into the warm shrimp.
  6. Transfer the mixture to the prepared casserole dish and spread into an even layer.
Topping
  1. Melt 1 tablespoon butter and stir in 1/2 cup panko breadcrumbs until coated. Sprinkle the panko evenly over the top.
Baking
  1. Bake uncovered for 13 to 15 minutes, or until the center reaches 145°F on an instant-read thermometer.
  2. Turn the broiler to high and broil the casserole for 1 to 2 minutes to brown the crumbs. Watch closely to avoid burning.
  3. Remove from the oven and let the casserole rest for 15 minutes before serving to allow the filling to set.

Notes

For a lighter topping, swap half the panko for crushed saltine crackers. For a dairy-free version, use vegan mayo and dairy-free shreds, but expect a different texture.
