Ingredients List

• 2 lbs large shrimp (21-24 count), peeled and deveined
• 1 tablespoon Old Bay Seasoning
• 1 tablespoon salt (for cooking water)
• ⅔ cup mayonnaise
• ½ teaspoon garlic powder
• ½ teaspoon ground black pepper
• 1 tablespoon butter (plus extra for greasing the dish)
• ½ cup panko breadcrumbs
• 4 ounces shredded mozzarella cheese
• 4 ounces shredded medium cheddar cheese

Step-by-Step Directions

1. Preheat the Oven and Prep the Dish

Preheat your oven to 375°F (190°C). Grease a 2 ½-quart casserole dish (or similar-sized pan) with butter to prevent sticking and enhance flavor.

2. Cook the Shrimp

Bring a large pot of water to a boil. Stir in 1 tablespoon salt and 1 tablespoon Old Bay Seasoning. Add the shrimp and cook for about 30 seconds, just until the shrimp turn opaque. Remove the shrimp using a strainer and transfer to a large mixing bowl. Let them cool slightly and drain any excess water using a paper towel if necessary.

3. Prepare the Filling

In the bowl with shrimp, add the mayonnaise, garlic powder, and black pepper. Stir until shrimp are evenly coated. Fold in the shredded mozzarella and cheddar cheeses to evenly distribute throughout the shrimp mixture.

4. Assemble the Casserole

Spread the shrimp and cheese mixture evenly into the greased casserole dish, ensuring shrimp and cheese are evenly spread.

5. Prepare the Topping

Melt 1 tablespoon butter in a small bowl. Stir in the panko breadcrumbs until fully coated. Sprinkle the buttered breadcrumbs evenly over the shrimp mixture.

6. Bake and Finish

Bake uncovered in the preheated oven for 13 to 15 minutes, or until the casserole reaches an internal temperature of 145°F. For a perfectly golden topping, switch the oven to broil for 1 to 2 minutes, watching closely to prevent burning.

7. Rest and Serve

Remove the casserole from the oven and let it rest for 10 to 15 minutes before serving. This allows the cheeses to set and flavors to meld together beautifully.

Serving Suggestions

This shrimp casserole offers a rich, creamy texture that pairs well with lighter, refreshing sides. Its cheesy base and buttery breadcrumb topping make it hearty, so it benefits from crisp salads, roasted vegetables, or bright citrus flavors to balance the meal.

For casual dinners, serve shrimp casserole straight from the baking dish with a sprinkle of freshly chopped parsley or chives. A squeeze of fresh lemon over the top brightens the richness, enhancing the natural sweetness of the shrimp.

At holiday gatherings or potlucks, present shrimp casserole alongside a medley of complementary sides. Its versatility allows you to pair it with everything from starches like rice or potatoes to crisp green salads or roasted vegetables. Whether served buffet-style or plated individually, shrimp casserole stands out as the centerpiece dish, drawing in seafood lovers and cheese enthusiasts alike.

If you’re serving it at a brunch, consider adding a seafood-friendly aioli or garlic butter drizzle to add an extra layer of flavor. For elegant presentations, garnish each serving with fresh dill or a sprinkle of Old Bay Seasoning to tie everything together.

Common Mistakes to Avoid

Perfecting shrimp casserole relies heavily on proper shrimp handling and attention to detail during assembly. Here are the most common mistakes and how to avoid them:

• Overcooking the Shrimp
  Shrimp cooks quickly, and overcooking leads to a rubbery texture. Boil shrimp for no more than 30 seconds before transferring them to the casserole. They will finish cooking in the oven.
• Using Pre-Cooked Shrimp
  Pre-cooked shrimp may seem convenient but can become overcooked and rubbery during baking. Fresh or thawed raw shrimp yields the best texture.
• Skipping Proper Draining
  Shrimp naturally release water during cooking. If excess moisture is not removed before assembling the casserole, the dish can become watery. Always pat shrimp dry thoroughly.
• Using Pre-Shredded Cheese
  Pre-shredded cheese often contains anti-caking agents that prevent smooth melting. Freshly shredded mozzarella and cheddar melt better and offer a creamier result.
• Skipping the Broil Step
  The final broil is essential for achieving the perfect golden, crispy breadcrumb topping. Monitor closely to avoid burning, but do not skip this step.
• Using the Wrong Pan Size
  A 2 ½-quart casserole dish works best to ensure even cooking and proper cheese coverage. A dish that’s too deep may prevent even heat distribution, while a dish that’s too shallow can lead to overcooked edges.
• Adding Breadcrumbs Too Early
  For the crispiest topping, add buttered breadcrumbs just before baking. Preparing them too far in advance can lead to soggy breadcrumbs.

Recipe Tips and Tricks

Making shrimp casserole is simple, but a few key tips can elevate it from good to exceptional. Proper ingredient preparation, strategic layering, and careful cooking times make all the difference.

• Choose Large Shrimp
  Larger shrimp hold their texture better during both boiling and baking. Smaller shrimp can become overcooked or lost in the cheese filling.
• Freshly Grate Your Cheese
  Pre-shredded cheese contains additives that prevent it from melting smoothly. Grating mozzarella and cheddar directly from the block ensures even melting and the perfect gooey texture.
• Pat Shrimp Dry Thoroughly
  Excess moisture can result in a watery casserole. After boiling the shrimp, pat them dry with paper towels to remove lingering water.
• Add Breadcrumbs at the Last Minute
  To ensure maximum crispiness, avoid adding the buttered panko topping until just before baking. This keeps the breadcrumbs from absorbing moisture from the casserole filling.
• Customize with Vegetables
  If you want to make this dish even heartier, consider adding sautéed mushrooms, baby spinach, or finely chopped bell peppers. Cook vegetables first to remove excess moisture.
• Broil for Perfect Color
  The final broil step ensures the breadcrumbs turn perfectly golden and crisp. Keep the casserole on the center rack and monitor closely to avoid burning.
• Test for Doneness
  A quick check with an instant-read thermometer can help ensure your shrimp casserole reaches 145°F, the safe internal temperature for shrimp.

Storage and Reheating Instructions

Proper storage keeps leftovers tasting fresh while preserving the shrimp’s tender texture and the casserole’s creamy consistency.

• Refrigeration
  Store leftover shrimp casserole in an airtight container. It will keep well in the refrigerator for up to 3 days. Avoid leaving it at room temperature for more than 2 hours.
• Freezing
  Although shrimp can become rubbery after freezing and reheating, you can freeze fully cooked shrimp casserole if needed. Wrap tightly in plastic wrap and foil or place in a freezer-safe container. Freeze for up to 1 month. Thaw in the refrigerator overnight before reheating.
• Reheating in the Oven
  For best results, reheat shrimp casserole in a preheated oven at 350°F. Cover loosely with foil to prevent drying out. Bake until warmed through, about 15 minutes. Remove the foil for the last few minutes to crisp up the breadcrumb topping.
• Reheating in the Air Fryer
  Individual portions can also be reheated in the air fryer at 325°F for 5 to 7 minutes. This method helps restore the breadcrumb topping’s crunch.
• Avoid Microwaving
  The microwave can make shrimp tough and rubbery while causing the cheese to separate. Use oven or air fryer methods whenever possible.
