Step‑by‑Step Instructions for Easy Shrimp Casserole
Step 1: Boil the Shrimp
Begin by bringing a large pot of water seasoned with salt to a rolling boil over high heat. Once boiling, carefully add the peeled and deveined shrimp, cooking them for about 2-3 minutes until they turn opaque and pink. Drain the shrimp and immediately cool them under cold running water to stop the cooking process. Set the cooled shrimp aside for later use in the Easy Shrimp Casserole.
Step 2: Prepare the Sauce
In a medium-sized mixing bowl, whisk together the mayonnaise, garlic powder, and black pepper until the mixture is smooth and creamy. This sauce will bring richness to the Easy Shrimp Casserole, so take your time to ensure all ingredients are well combined. Set this bowl aside, as it will be blended with the shrimp shortly.
Step 3: Mix the Shrimp and Sauce
In a large mixing bowl, gently combine the cooked shrimp with the mayonnaise mixture you prepared earlier. Add Old Bay seasoning to the mix, tossing everything together gently until the shrimp are completely coated. This will create the flavorful base for the casserole, ensuring each bite is deliciously seasoned.
Step 4: Preheat the Oven
While you mix the ingredients, preheat your oven to 375°F (190°C). This will ensure your Easy Shrimp Casserole bakes evenly and efficiently. As the oven heats, take a 9×13 inch baking dish and grease it thoroughly with butter or cooking spray to prevent sticking.
Step 5: Assemble the Casserole
Pour the shrimp mixture evenly into the greased baking dish, spreading it out to create an even layer. This step is vital to ensure that every part of the dish receives that creamy flavor. Gently press down to compact the mixture slightly, preparing it for the crispy topping to come.
Step 6: Create the Topping
In a small bowl, combine the panko breadcrumbs, mozzarella, and cheddar cheese. Stir until evenly mixed, then sprinkle this cheesy, crunchy mixture generously over the shrimp layer in the casserole. For added indulgence, you can dot the top with small pieces of butter to enhance browning and flavor.
Step 7: Bake the Casserole
Carefully place the assembled Easy Shrimp Casserole into the preheated oven. Bake for 20-25 minutes or until the topping is golden brown and bubbly, indicating it’s ready. Keep an eye on it towards the end of baking to prevent over-browning.
Step 8: Rest and Serve
Once out of the oven, allow the casserole to rest for about 5-10 minutes. This will make it easier to serve, ensuring the layers set slightly. You will see a delightful bubbling around the edges, and the crispy topping will be hard to resist. Enjoy your family-friendly Easy Shrimp Casserole!
