Ingredient List (Serves 8)

For the Shrimp Mixture:

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
½ tsp garlic powder
½ tsp ground black pepper
4 oz shredded mozzarella cheese
4 oz shredded medium cheddar cheese

For the Topping:

1 Tbsp butter (melted)
½ cup panko breadcrumbs

Additional Needs:

Butter for greasing the pan

Step-by-Step Directions

1. Prep the Oven and Dish

Preheat your oven to 375°F.
Lightly grease a 2 ½-quart casserole dish (or a 9×9 pan, pie pan, or deep skillet) with butter.

2. Cook the Shrimp

Bring a large pot of water to a boil. Add 1 Tbsp salt and 1 Tbsp Old Bay Seasoning.
Carefully add the shrimp to the pot 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 slightly, then drain any excess water from the bowl (use a paper towel if needed).

Pro Tip: Ensure the shrimp are completely thawed and patted dry before cooking to avoid excess moisture.

3. Prepare the Filling

To the shrimp, add the mayonnaise, garlic powder, and black pepper. Stir until the shrimp are evenly coated.
Sprinkle in the shredded mozzarella and cheddar cheeses. Mix gently until combined.
Transfer the mixture into the greased casserole dish, spreading it evenly.

4. Make the Topping

In a small bowl, melt 1 Tbsp butter. Add the panko breadcrumbs and stir until they are evenly moistened.
Sprinkle the breadcrumbs over the shrimp mixture.

5. Bake the Casserole

Place the casserole dish in the preheated oven and bake uncovered for 13-15 minutes, or until the center reaches 145°F (use an instant-read thermometer).
To achieve a golden crust, broil the dish for an additional 1-2 minutes.

6. Rest and Serve

Let the casserole rest for 15 minutes before serving. This allows the flavors to meld and ensures the topping stays crisp.

Pro Tips and Variations

Cheese Options: Swap mozzarella or cheddar for Parmesan or Gruyère for a more gourmet flavor.
Topping Twist: Mix in grated Parmesan or dried herbs with the panko breadcrumbs for extra flavor.
Make Ahead: Prepare the shrimp mixture in advance and refrigerate for up to 3 days. Add breadcrumbs just before baking.

Common Mistakes to Avoid and How to Perfect the Recipe

Even though this shrimp casserole recipe is simple, here are a few common mistakes to watch out for:

Overcooking the Shrimp
- Why It’s a Problem: Shrimp can become rubbery if cooked too long.
- Solution: Cook them for only 30 seconds until opaque and immediately transfer them out of the hot water.
Excess Liquid in the Casserole
- Why It’s a Problem: Excess moisture can lead to a watery casserole.
- Solution: Thoroughly pat shrimp dry with paper towels and drain any liquid before combining ingredients.
Uneven Breadcrumb Topping
- Why It’s a Problem: Certain spots may brown faster than others or stay pale.
- Solution: Spread breadcrumbs evenly and check the casserole frequently during broiling.
Skipping the Resting Time
- Why It’s a Problem: Serving immediately may result in a runny texture, as the dish hasn’t set.
- Solution: Allow the casserole to rest for 15 minutes to let the flavors meld and topping stay crisp.
Using the Wrong Cheese
- Why It’s a Problem: Some cheeses don’t melt evenly or pair well with shrimp.
- Solution: Stick to mozzarella, cheddar, Parmesan, or Gruyère for a smooth and flavorful finish.

Side Dish Pairing Tips

For Lighter Meals: Pair the casserole with a fresh salad or sautéed vegetables to keep the meal balanced.
For Indulgent Occasions: Add starchy sides like mashed potatoes or buttery rolls for a hearty spread.
Wine Pairing: Serve with a crisp white wine, such as Sauvignon Blanc or Chardonnay, to complement the shrimp’s delicate flavors.

Recipe Tips for Success

Ingredient Variations
- Add cooked bacon bits or diced jalapeños for an extra punch of flavor.
- Swap the cheddar for Gruyère or Parmesan to elevate the dish’s cheesiness.
Breadcrumb Topping Twist
- Mix grated Parmesan or a pinch of dried Italian herbs into the breadcrumbs for added depth.
Make Ahead Convenience
- Prepare the shrimp filling up to 3 days in advance and store it in the fridge. Add the breadcrumb topping just before baking.
Serving Warm or Room Temperature
- This dish is excellent served warm but also holds up well at room temperature, making it ideal for potlucks or transport.
Balance the Flavors
- If you prefer a lighter flavor, reduce the mayonnaise to ½ cup or replace part of it with Greek yogurt.

Storage and Reheating Instructions

Storing Leftovers
- Store leftover casserole in an airtight container in the refrigerator for 2–3 days.
Reheating
- For the best results, reheat in a 350°F oven for 10–12 minutes until warm.
- Alternatively, use an air fryer to revive the crispy breadcrumb topping.
- Avoid microwaving, as it can make the shrimp rubbery and the breadcrumbs soggy.
Freezing Note
- While freezing is possible, the creamy filling may separate when thawed. For best results, enjoy the casserole fresh.
