Ingredients
- 2 lbs large shrimp (21–24 count), peeled and deveined
- 1 Tbsp Old Bay Seasoning
- 1 Tbsp salt (for boiling water)
- 2/3 cup mayonnaise
- 1/2 tsp garlic powder
- 1/2 tsp ground black pepper
- 1 Tbsp butter, plus more for greasing the dish
- 1/2 cup panko breadcrumbs
- 4 oz shredded mozzarella cheese
- 4 oz shredded medium cheddar cheese
Instructions
- Preheat the oven to 375°F (190°C). Grease a 2½-quart casserole dish or oven-safe skillet with butter.
- 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 about 30 seconds, just until opaque. Remove shrimp with a strainer and transfer to a large mixing bowl.
- Let the shrimp cool for a few minutes, then drain or blot excess moisture with paper towels.
- Add mayonnaise, garlic powder, and black pepper to the shrimp and stir to coat. Mix in mozzarella and cheddar cheese.
- Transfer the mixture to the prepared casserole dish and spread evenly.
- Melt 1 Tbsp butter and mix with the panko breadcrumbs until evenly moistened. Sprinkle over the top of the casserole.
- Bake uncovered for 13–15 minutes, or until the internal temperature reaches 145°F. Broil for 1–2 minutes to brown the breadcrumbs.
- Let rest for 15 minutes before serving. Serve warm or at room temperature.
Notes
- Use freshly grated cheese for the best melting and texture.
- Don’t overcook the shrimp—only 30 seconds is needed in boiling water.
- This casserole transports well and tastes great at room temperature.
- You can substitute different cheeses like Monterey Jack or Gruyère for a twist.
