- 1 Tbsp Old Bay Seasoning
- 1 Tbsp salt for cooking water
- 2/3 cup mayonnaise
- 1/2 tsp garlic powder
- 1/2 tsp ground black pepper
- 1 Tbsp butter plus extra to grease the pan
- 1/2 cup panko breadcrumbs
- 4 oz shredded mozzarella cheese
- 4 oz shredded medium cheddar cheese
Instructions
Prep the Oven and Dish
- Preheat the oven to 375°F.
- Grease a 2 1/2-quart casserole dish (or a 9x9 square dish, 9-inch pie pan, or deep 10-inch skillet) with butter.
Cook the Shrimp
- Bring a large pot of water to a boil. Add 1 Tbsp salt and 1 Tbsp Old Bay Seasoning.
- Add the shrimp and cook for 30 seconds, just until opaque and cooked through.
- Remove the shrimp using a strainer and transfer to a large mixing bowl.
- Let the shrimp cool for a few minutes, then drain any excess water from the bowl (use a paper towel if necessary).
Prepare the Filling
- To the shrimp, add mayonnaise, garlic powder, and black pepper. Stir to coat the shrimp evenly.
- Sprinkle in the shredded mozzarella and cheddar cheeses, and stir again to combine.
- Transfer the shrimp mixture to the prepared casserole dish, spreading it evenly.
Make the Topping
- In a separate bowl, melt 1 Tbsp butter and stir in the panko breadcrumbs until evenly moistened.
- Sprinkle the breadcrumbs over the shrimp mixture.
Bake the Casserole
- Bake uncovered at 375°F for 13-15 minutes, or until the center reaches 145°F (use an instant-read thermometer).
- Broil for 1-2 minutes to brown the breadcrumbs.
- Let the casserole rest for 15 minutes before serving. It can be served warm or at room temperature, making it a great dish for transport.
