Shrimp Casserole Recipe Ingredients
For the Casserole
• Shrimp – Use fresh or frozen for the best results; just make sure they are cooked until just opaque for tenderness.
• Mayonnaise – This adds a rich creaminess; Greek yogurt is a great substitute for a lighter option.
• Mozzarella Cheese – Provides that delightful gooey texture; feel free to swap it with any other melting cheese you enjoy.
• Cheddar Cheese – Adds a sharp and tangy flavor; mixing with milder cheese can create a balanced profile.
• Garlic Powder – Enhances the overall flavor; fresh minced garlic can be a perfect substitute if you prefer a bolder taste.
• Old Bay Seasoning – This classic seafood seasoning gives aromatic depth; any other seafood seasoning can work in a pinch.
For the Topping
• Panko Breadcrumbs – Creates a wonderfully crispy layer; regular breadcrumbs can be used but won’t provide the same crunch.
• Butter – Binds the breadcrumbs together while adding richness; olive oil is a fantastic dairy-free alternative.

Step‑by‑Step Instructions for Creamy Shrimp Casserole with Crispy Breadcrumb Topping
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms, take a 9×13-inch casserole dish and generously grease it with butter to prevent sticking. This step sets the stage for your delightful Shrimp Casserole, ensuring a beautifully cooked bottom layer that melds the flavors together.
Step 2: Cook the Shrimp
In a medium pot, bring salted water to a boil and add a dash of Old Bay seasoning for flavor. Gently toss the shrimp into the boiling water and cook for about 30 seconds, or until they turn just opaque. Drain the shrimp and transfer them to a mixing bowl, allowing any excess moisture to escape as you prepare the rest of the casserole.
Step 3: Season the Shrimp
Once the shrimp have cooled slightly, add the mayonnaise, garlic powder, and a sprinkle of black pepper to the bowl. Mix everything gently until the shrimp are generously coated in the creamy mixture, ensuring even flavor distribution. This step is essential for a rich and savory base in your Shrimp Casserole.
Step 4: Add the Cheeses
Fold in the shredded mozzarella and cheddar cheese into the shrimp mixture, combining them until everything is well integrated. This cheesy blend will melt beautifully during baking, creating that gooey, indulgent texture we all crave. Make sure to mix thoroughly so each bite is loaded with deliciousness.
Step 5: Assemble the Casserole
Transfer the shrimp and cheese mixture into your prepared casserole dish, spreading it evenly across the bottom. Take a moment to smooth the top with a spatula for a visually appealing result. This layer serves as the heart of your Shrimp Casserole, showcasing the delicious shrimp and cheese on the plate.
Step 6: Prepare the Topping
In a small saucepan, melt butter over low heat. Once melted, remove from heat and mix in the panko breadcrumbs until they’re lightly coated. This flavorful topping will provide the perfect crunchy contrast to the creamy casserole underneath. Generously sprinkle the breadcrumb mixture over the shrimp-layered casserole.
Step 7: Bake the Casserole
Place the assembled casserole in the preheated oven and bake uncovered for 13-15 minutes. You’ll know it’s ready when the center reaches an internal temperature of 145°F and the edges start to bubble invitingly. The top should be turning a lovely golden hue, signaling the fabulous crust about to delight your taste buds.
Step 8: Broil for Extra Crunch
For that irresistible crispy topping, switch to the broil setting on your oven. Broil the casserole on high for 1-2 minutes, keeping a close eye to prevent burning. This final touch enhances the texture, providing a gorgeous golden crust that contrasts delightfully with the creamy filling of your Shrimp Casserole.
Step 9: Rest Before Serving
Once baked and broiled to perfection, take the casserole out of the oven and let it rest for about 15 minutes. Allowing the dish to sit helps the flavors meld beautifully and makes it easier to serve. As it cools, the delightful aroma will fill your kitchen, inviting everyone to gather around for a truly comforting meal.
