how to make Shrimp Casserole

Ingredients

2 pounds large shrimp (21-24 count), peeled and deveined
1 tablespoon Old Bay seasoning, plus 1 tablespoon salt for cooking water
2/3 cup mayonnaise
1/2 teaspoon garlic powder
1/2 teaspoon ground black pepper
1 tablespoon butter, plus more to grease the pan
1/2 cup panko bread crumbs
4 ounces shredded mozzarella cheese
4 ounces shredded medium cheddar cheese

Directions

Preheat your oven to 375°F (190°C). Grease a 2 1/2 quart casserole dish with butter.
In a large pot, bring salted water to a boil. Add the Old Bay seasoning.
Add the shrimp to the boiling water and cook until they turn opaque, about 30 seconds. Drain the shrimp and transfer them to a bowl.
In the bowl with the shrimp, add the mayonnaise, garlic powder, and pepper. Stir to coat the shrimp evenly.
Add the shredded mozzarella and cheddar cheese to the bowl and stir again to combine.
Transfer the shrimp mixture to the prepared casserole dish.
Melt the butter and mix it with the panko bread crumbs. Sprinkle this mixture evenly over the shrimp.
Bake the casserole uncovered for 13-15 minutes, or until the center reaches 145°F. Broil for 1-2 minutes to brown the crumbs if desired.
Let the casserole rest for 15 minutes before serving.
