Ingredients
- 2 lbs large shrimp
- 1 Tbsp Old Bay Seasoning (plus 1 Tbsp salt for the cooking water)
- 2/3 cup mayonnaise
- 1/2 tsp garlic powder
- 1/2 tsp ground black pepper
- 4 oz shredded mozzarella cheese
- 4 oz shredded medium cheddar cheese
- 1 Tbsp butter (plus more to grease the pan)
- 1/2 cup panko bread crumbs
Instructions
- Step 1: Preheat your oven to 375°F (190°C). Grease a 2 1/2 quart casserole dish or skillet with butter to prevent sticking and add flavor.
- Step 2: Bring a large pot of water to a boil. Add 1 tablespoon of salt and 1 tablespoon of Old Bay Seasoning to the boiling water. Add the shrimp and cook for about 30 seconds or just until they turn opaque and are cooked through. Immediately strain the shrimp and transfer them to a large mixing bowl. Allow to cool for a few minutes, then drain off any excess liquid by pouring it out or blotting with a paper towel.
- Step 3: To the shrimp, add mayonnaise, garlic powder, and ground black pepper. Stir well to coat all the shrimp evenly. Next, sprinkle shredded mozzarella and cheddar cheeses onto the shrimp and stir gently until combined. Transfer this mixture evenly into the prepared casserole dish.
- Step 4: Melt 1 tablespoon of butter in a separate bowl or measuring cup. Stir in the panko bread crumbs until they are evenly moistened with butter. Evenly sprinkle the breadcrumb mixture over the shrimp in the casserole dish.
- Step 5: Bake the casserole uncovered at 375°F (190°C) for 13 to 15 minutes, or until the center reaches 145°F (63°C) when checked with an instant-read thermometer. Then switch your oven setting to broil and broil for 1 to 2 minutes to brown the breadcrumb topping, creating a crispy golden crust.
- Step 6: Remove the casserole from the oven and let it rest for 15 minutes before serving. The dish can be enjoyed warm or at room temperature.
Tips & Variations
- Substitute the mayonnaise with Greek yogurt for a lighter version without losing creaminess.
- Add a pinch of cayenne pepper to the shrimp mixture for a subtle spicy kick.
- Use fresh breadcrumbs instead of panko for a different texture in the topping.
- Swap mozzarella or cheddar with your favorite cheeses like pepper jack or gouda for new flavor twists.
Storage
Store any leftovers covered in the refrigerator for up to 3 days. To reheat, warm the casserole in the oven at 350°F (175°C) until heated through to maintain the crispy breadcrumb topping. Microwaving is quicker but may soften the crust.
