How to Make Creamy Shrimp Casserole with Cheddar, Mozzarella, and Panko Breadcrumb Topping Recipe
Step 1: Prepare the Oven and Casserole Dish
Start by heating your oven to 375°F (190°C). Grease your casserole dish generously with butter. This step ensures your casserole doesn’t stick and helps the edges get golden and deliciously crisp.
Step 2: Cook the Shrimp
Bring a large pot of salted water to a boil and add the Old Bay seasoning for extra flavor. Drop in the shrimp and cook them until opaque, which should only take about 30 seconds. Quick cooking keeps the shrimp tender and juicy. Drain thoroughly and transfer the shrimp to a large mixing bowl to cool slightly.
Step 3: Combine the Creamy Mixture
Add mayonnaise, garlic powder, black pepper, shredded mozzarella, and cheddar cheese to the shrimp. Stir everything together gently but thoroughly to make sure every piece of shrimp is coated with this rich, cheesy blend. The mayo and cheeses create a dreamy, velvety texture that acts like a flavorful glue.
Step 4: Assemble the Casserole
Pour the shrimp and cheese mixture into your prepared casserole dish, spreading it out evenly. This will give you that perfect harmony of flavors in every forkful.
Step 5: Prepare the Panko Breadcrumb Topping
Melt some butter in a small bowl and mix it with the panko breadcrumbs until they’re coated and ready to crisp up in the oven. Sprinkle this golden topping evenly over the shrimp mixture. That buttery crunch is the final touch that transforms this casserole from comforting to unforgettable.
Step 6: Bake and Rest
Bake uncovered for 13 to 15 minutes, until the casserole is bubbling hot and the breadcrumb topping has turned a beautiful golden brown. Once out of the oven, let it rest for 15 minutes to allow the flavors to settle and the casserole to firm up slightly for perfect slicing and serving.

Garnishes
To brighten each bite, garnish with some fresh chopped parsley or a sprinkle of chopped chives. These herbs add a fresh pop of color and a gentle herbal note that cuts through the rich creaminess. A wedge of lemon on the side also makes a fantastic option for those who like to squeeze a bit of citrus zing onto their seafood.
Side Dishes
This casserole pairs beautifully with crisp green salads or roasted vegetables like asparagus or broccoli, which provide a refreshing and textural contrast. For a heartier meal, serve alongside buttery mashed potatoes or fluffy rice to soak up every last bit of the creamy sauce.
Creative Ways to Present
Try serving the casserole in individual ramekins for a charming presentation at dinner parties or potlucks. You can also layer the shrimp mixture into a large baking dish, then swirl in some spicy marinara or add a sprinkle of parmesan for an Italian-inspired twist that will wow your guests.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate for up to 3 days. The casserole remains delicious, and the flavors continue to meld, making for a delightful next-day meal.
Freezing
This shrimp casserole freezes well if you want to prepare in advance. Cover tightly with plastic wrap and aluminum foil, then freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
Reheat leftovers in a 350°F (175°C) oven until warmed through and the breadcrumb topping regains some crispness, about 15 minutes. Avoid the microwave if possible to keep the crust crunchy and the shrimp tender.
FAQs
Can I use frozen shrimp for this casserole?
Absolutely! Just be sure to thaw the shrimp completely and pat them dry before cooking to maintain the best texture and prevent extra wateriness in your casserole.
Is there a substitute for mayonnaise?
You can try using sour cream or Greek yogurt as a lighter alternative, though it will slightly alter the texture and flavor. The richness of mayonnaise really helps achieve that creamy consistency.
Can I add vegetables to this casserole?
Yes! Chopped spinach, peas, or even diced bell peppers can be mixed in to add color and nutrition without compromising the cheesy, shrimp-forward flavor.
What if I don’t have Panko breadcrumbs?
Regular breadcrumbs can work, but panko is preferred for its extra crunchiness and light texture. You might also try crushed crackers or toasted nuts for a creative twist.
How spicy is this casserole?
It’s mildly spiced thanks to Old Bay seasoning and black pepper, designed to enhance the shrimp’s flavor without overwhelming it. You can always add extra if you prefer more heat.
